Everyday Items That May Be Hindering Your Health

Everyday items could be causing everything from mood swings to infertility and even cancer.

Chemicals found in plastic water bottles, lipsticks, tampons, receipts and even tap water are wreaking havoc on people’s hormones, which is linked to a growing number of health problems.

Research published earlier this week reveals more than 90 percent of receipts contain the so-called ‘gender-bending’ chemical Bisphenol A (BPA) and its ‘healthier alternative’ Bisphenol S (BPS), which are associated with autism, ADHD, type 2 diabetes, premature births and early onset of puberty, reports the Daily Mail.

Researchers from the Michigan-based non-profit organisation The Ecology Center analyzed 207 paper receipts from a variety of businesses collected between January and April 2017.

However despite their health concerns, such chemicals are frequently added to day-to-day products to provide scent and extend their shelf life.

In a piece for Healthista, editor Anna Magee speaks to reproductive experts, nutritional therapists and dentists on how to avoid such chemicals and detox your life.

Most of us take the mood swings, grumpiness and weight gain of fluctuating hormones for granted.

Yet toxic chemicals in our everyday lives could be making things worse.

Known as ‘xenoestrogens’, these substances, which are found in plastics, cosmetics, sanitary products, receipts and even tap water can mimic the hormone oestrogen and are linked not only to middle-aged spread but also reproductive problems, learning difficulties and even cancer.

Dr Channa Jayasena, a clinical senior lecturer and consultant in reproductive endocrinology at Imperial College London, said: ‘We know little about such hormone altering chemicals but our increasing exposure to them is a cause for concern.

“The risk of these endocrine-disrupting chemicals is enormous and we’re just at the start of learning what they do.
“My concern is that by the time we work out what they actually do, they might be causing diseases we don’t know about.”

So, what can you do? Start by identifying the sources of fake oestrogens in your life and take simple steps to detox them.

Water bottles and other plastics

Dr Jayasena said: “Chemicals in plastics behave like oestrogen in our systems when they reach our bloodstream.”

Chief offender is BPA found in plastic containers, water bottles and linings for tinned foods and drinks. A 2016 study revealed that two out of three canned foods tested positive for BPA.

A survey by the US Centers for Disease Control found that 93 per cent of the population had measurable amounts of BPA in their systems.

According to the Food Standards Agency, there is European legislation in place which sets a maximum limit on BPA from plastics, however, such risks are being re-evaluated by European authorities due to new scientific information emerging on the dangers of such exposure.

BPA and other xenoestrogens not only effect our waistlines but also our reproductive systems.

Dr Jayasena said: “Men’s sperm counts have decreased dramatically in the last decade and we’re now looking at the part hormone disrupting chemicals in our packaging, food and water play in this.”

Dr Sara Gottfried, a US gynaecologist and author of “The Hormone Cure” and new book, “Younger: The Breakthrough Programme to Reset our Genes and Reverse Ageing”, added: “Many problems are co-related with BPA from weight gain to endometriosis and breast cancer.

“This and other xenoestrogen chemicals build up in the body, accelerating ageing and hindering weight loss.”

While some companies market plastic products as “BPA-free”, substitute chemicals, known as BPS and BPF, may be just as dangerous.

A study in April this year by the Endocrine Society in the US found that exposure to BPS could increase the aggressiveness of breast cancer, while a paper published in Environmental Health Perspectives in 2015 reviewed 32 studies on the subject and found that all three chemicals are hormone disruptors linked to problems such as weight gain and reproductive issues.

• How to detox

Dr Gottfried said: “Heat, microwave use, dishwasher use or leaving a plastic water bottle in the sun can all release such chemicals.

“Avoid microwaving your food with cling film over it or while it’s in plastic containers.
“Use stainless steel water bottles where you can, cook and store food in glass, ceramic or stainless steel, and use glass or microwave-safe ceramics for microwaving.
“If you must use plastic containers, don’t heat them up”.

She also recommends people try and avoid tinned food or rinse their contents carefully before eating.

BPA is found in plastic water bottles, containers, and linings for tinned food and drinks.

Tap water, fruit and vegetables

Dr Jayasena said: “Xenoestrogen chemicals are in our water supply, fruit and vegetables thanks to their use in farming.”

For example, while DDT, a pesticide with proven hormone-disrupting effects, has been banned, glyphosate, a similar xenostrogen chemical linked to breast cancer and obesity, which is found in the common garden weedkiller Round Up, is still commonly available.

Round Up is one of many pesticides used in Britain that is made from chemicals with endocrine-disrupting effects, the residues of which leech into our tap water and rivers, and remains on the skin of fruit and vegetables.

• How to detox

Dr Gottfried recommends people drink filtered water, using carbon to absorb impurities and contaminants. Reverse osmosis filters can remove more chemicals but require fitting to taps at home and can be expensive.

Nutritional therapist Daniel O’Shannessy, who is also director of Bodhimaya Health Centre, says people can remove pesticides from the skin of fruit and vegetables by soaking them in water and a tablespoon of apple cider vinegar before cooking.

They can also check websites such as the Environmental Working Group (ewg.org) for their “dirty dozen” and “clean fifteen”; lists of the most and least contaminated produce.

More than 90 percent of receipts contain the so-called ‘gender-bending’ chemical BP.

Receipts, sanitary products and napkins

Dr Gottfried said: “The shiny coating on receipts is giving you a dose of BPA every time you touch it and we know the skin absorbs such chemicals almost as well as when we ingest them.”
France is seeking an EU-wide ban on till receipts containing BPA, with most of its receipts being marked “sans BPA”.

Such sources of synthetic oestrogens contribute to your overall toxic load, increasing your risk of oestrogen dominance.

Other paper sources of synthetic oestrogens include sanitary towels and tampons, which contains xenoestrogens called dioxins – and are linked to fertility, immune issues and endometriosis – as well as table napkins, which may be coated in BPA.

• How to detox

Try and go receipt free, and look for organic or dioxin-free sanitary products that have not been bleached or dyed. Also opt for unbleached, uncoated napkins.

Dental fillings

BPA is used in plastics, with the resins making composite fillings.

A 2010 study published in the Journal of Dental Hygiene found that BPA was found in the saliva of all 30 dental patients surveyed, while further research in 2012, published in the journal Paediatrics, found that children fitted with fillings made from a substance containing BPA show more behavioural problems compared to their peers.

• How to detox

Dentist James Goolnik of Bow Lane Dental Group, said: “Composite fillings are the least expensive [around £200 a tooth (NZD $380)] of all fillings after mercury and, as mercury has so many confirmed dangers, many people opt for composite.

“But while many contain synthetic oestrogen chemicals such as BPA, it’s now possible to ask for BPA-free composite fillings”.
“Alternatively, porcelain won’t contain toxic chemicals, is tooth coloured, more durable than composite and is about £500 (NZD $952) a tooth.
“If the filling isn’t visible, the best option is gold as it virtually lasts forever, is kinder to your tooth and also contains no toxic chemicals but at around £800 (NZD $1,523) a filling, it’s pricey.
“I still wouldn’t recommend having plastic fillings removed because of the BPA effect as the removal process not only leads to more tooth tissue being damaged it can aggravate the release of more chemicals into the system.”

Cosmetics

That lipstick you cannot live without could be adding to your ostrogen load.

In the 1990s, chemicals known as parabens in body creams, lipsticks, scrubs, shampoos and more were identified as xenoestrogens, while in 2004, British researcher Philippa Darbre found them in breast cancer cells.

Likewise, a family of chemicals known as sulphates also have an oestrogen-like effect on the body and are responsible for create lathers in shampoos, body washes, detergents and soaps.

• How to detox

Dr Gottfried said: “Ignore labels such as chemical-free, ‘natural’ or ‘for sensitive skin’ as these have no regulated meaning.

Instead, opt for organic skincare and make-up, or products that are sulphate- and paraben-free.

Perfumes and scented candles

Dr Gottfried said: “Many commercial perfumes and scented candles contain phthalates, a class of chemicals found in a surprising number of common household products such as shampoos, deodorants, body washes, hair gels and nail polishes.
“There’s little doubt phthalate chemicals are a key contributor to the inability to lose weight caused by oestrogen dominance.
“Research into the effects of phthalate is ongoing but we know they cause birth defects in male foetuses, are associated with poor egg quality and early menopause in women, and may also be linked to breast cancer and type-2 diabetes”.

• How to detox

Look for phthalate-free cosmetics and unscented candles, ideally made from soya wax.

High-grade essential oils in water used with an oil burner are also a great alternative to scented candles.

Three ways to detox excess oestrogen

Simple lifestyle measures can help, according Daniel O’Shaunnessy, a nutritional therapist at the Bodhimaya Health Centre.

• Eat flaxseeds

Constipation can lead to hormonal imbalances by slowing down the passing of hormones from food and water through the gut. Flaxseeds contain fibre that helps ease this.

Try a tablespoon soaked overnight in a glass of water and then added to smoothies, porridge or taken neat.

• Eat broccoli

Cruciferous vegetables, such as broccoli and cauliflower, help detoxify fake oestrogen from the liver.

• Take a probiotic

This will help balance the beneficial microflora in your gut, which can help increase motility, meaning you eliminate toxins faster.

Selenium: What It Does and Where To Find It

Selenium Protects a Specific Type of Interneurons in The Brain

Exactly 200 years ago, the Swedish scientist Jöns Jacob Berzelius discovered the trace element selenium, which he named after the goddess of the moon, Selene. Besides its industrial applications (chemical industry, production of semiconductors and toners), selenium is an essential trace element and indispensable for humans, many animals and some bacteria. A team led by Dr. Marcus Conrad, research group leader at the Institute of Developmental Genetics (IDG) at Helmholtz Zentrum München, showed for the first time why selenium is a limiting factor for mammals.

Scientific ‘by-catch’ solves decades-old mystery

The scientists have been investigating for years the processes of a novel type of cell death, known as ferroptosis. In this context, the enzyme GPX4, which normally contains selenium in the form of the amino acid selenocysteine, plays an important role.

In order to better understand the role of GPX4 in this death process, we established and studied mouse models in which the enzyme was modified,” said study leader Conrad. “In one of these models, we observed that mice with a replacement of selenium to sulfur in GPX4 did not survive for longer than three weeks due to neurological complications.”

In their search for the underlying reasons, the researchers identified a distinct subpopulation of specialized neurons in the brain, which were absent when selenium-containing GPX4 was lacking. “In further studies, we were able to show that these neurons were lost during postnatal development, when sulfur- instead of selenium-containing GPX4 was present,” stated first author of the study, Irina Ingold.

Furthermore, the scientists were able to show that ferroptosis is triggered by oxidative stress, which is known to occur for instance during high metabolic activity of cells and high neuronal activity. “Our study demonstrates for the first time that selenium is an essential factor for the postnatal development of a specific type of interneurons,” said Dr. José Pedro Friedmann Angeli, a scientist at the IDG, describing the results. “Selenium-containing GPX4 protects these specialized neurons from oxidative stress and from ferroptotic cell death.”

Thus, the study explains why certain selenoenzymes are essential in some organisms, including mammals, whereas they are dispensable in other organisms, such as fungi and higher plants. In future investigations, study leader Marcus Conrad and his team aim to investigate how ferroptosis is triggered in cells. As a long-term goal, he wants to elucidate the role of ferroptosis in various disease conditions in order to be able to alleviate diseases, such as cancer or neurodegeneration, which are currently difficult to tackle.

10 Foods Rich in Selenium

Selenium Function

This important nutrient is vital to immune system function. Selenium works in conjunction with vitamin E, vitamin C, glutathione and vitamin B3 as an antioxidant to prevent free radical damage in the body. It’s thought to help prevent cancer by affecting oxidative stress, inflammation and DNA repair. Selenium has been found to be important to male fertility; increasing selenium levels leads to improved sperm motility. There is preliminary research that suggests that selenium supplementation may also help with asthma symptoms, but more studies are needed.

Selenium Deficiencies

Deficiencies of selenium can occur in areas where soil content of this mineral is low. Diets high in refined foods may also lead to deficiency, as selenium can be destroyed by food processing. Taking anti-inflammatory drugs may reduce the body’s supply of selenium.

Low selenium levels can contribute to autoimmune problems, such as psoriasis and thyroid disease. Low levels have also been tied to stomach, throat and prostate cancers, although more research is needed to determine if this is a cause or a result of the disease. Some studies suggest that selenium deficiency is linked to mood disorders. There’s indication that deficiencies in selenium may contribute to the progression of viral infections.

10 Selenium Food Sources

The selenium content in foods depends on the concentration of selenium in the soil where the crops were grown. The following foods are generally considered good sources of selenium:

  • Brazil Nuts
  • Sunflower Seeds
  • Fish (tuna, halibut, sardines, flounder, salmon)
  • Shellfish (oysters, mussels, shrimp, clams, scallops)
  • Meat (Beef, liver, lamb, pork)
  • Poultry (chicken, turkey)
  • Eggs
  • Mushrooms (button, crimini, shiitake)
  • Grains (wheat germ, barley, brown rice, oats)
  • Onions

Recommended Daily Allowance

  • Children (under 3): 20 mcg
  • Children (4-8): 30 mcg
  • Children (9-13): 40 mcg
  • Adolescents (14-18): 55 mcg
  • Adults 19 and older: 55 mcg
  • Pregnant women: 60 mcg
  • Lactating women: 70 mcg

Toxicity

Exceeding 400 mcg per day can lead to selenium toxicity. Side effects may include hair loss, white spots on fingernails, fatigue, dizziness, nausea and nerve damage. There’s some evidence that high selenium levels may increase the risk of squamous cell skin cancer. Another well controlled study found a correlation between higher levels of selenium and an increased risk of developing type-2 diabetes.

Because of the possibility of toxicity, selenium supplements are controversial. The safest way to ensure a sufficient level of selenium in the diet is by eating a variety of selenium rich foods, like those listed above. Brazil nuts can be very high in selenium and should only be eaten occasionally. One Brazil nut can supply a whole day’s requirement of selenium, although this can vary depending on soil conditions. A multivitamin that contains some selenium is safe for most people to take and can help to fill the gap in a diet that is lacking.

Gum Disease Tied to Yet Another Deadly Illness

Add one more reason to why you should brush and floss regularly: Gum disease bacteria are now tied to higher odds of esophageal cancer.

The study tracked the oral health of 122,000 Americans for 10 years. It found that the presence of two types of bacteria linked with gum disease may hike the risk of the cancer.

The presence of one oral bacterium in particular, called Tannerella forsythia, was tied to a 21 percent increase in the odds of developing esophageal tumors, said a team led by Jiyoung Ahn. She is associate director for population science at NYU Langone Health in New York City.

Gum disease has already been linked in numerous studies to a heightened risk of the number one killer, heart disease. But an expert in esophageal cancer who reviewed the new findings stressed that researchers can’t yet prove a causal link to esophageal tumors.

“What is not clear is whether the presence of these bacteria or the resultant periodontal disease is primarily responsible for the development of cancer,” said Dr. Anthony Starpoli, associate director of esophageal endotherapy at Lenox Hill Hospital in New York City.
Still, Starpoli believes specialists should “consider a proper evaluation of the oral cavity as well as the remainder of the digestive tract in the hope of early diagnosis of esophageal cancer.”

Esophageal cancer is the eighth most common cancer and the sixth leading cause of cancer death worldwide, the study authors noted. Because it’s often only diagnosed at an advanced stage, five-year survival rates are between 15 to 25 percent.

Ahn said, “Esophageal cancer is a highly fatal cancer, and there is an urgent need for new avenues of prevention, risk stratification, and early detection.”

The news from the study wasn’t all bad: The investigators found that some types of mouth bacteria were associated with a lower risk of esophageal cancer.

Learning more about the bacteria communities living naturally in the mouth “may potentially lead to strategies to prevent esophageal cancer, or at least to identify it at earlier stages,” Ahn noted in a news release from the American Association for Cancer Research.

One other expert agreed.

“The study suggests that there are some oral bacteria that may contribute to the development of this highly deadly cancer but also, and very importantly, suggests that some bacteria may provide a protective effect,” said Dr. Robert Kelsch. He’s an oral pathologist at Northwell Health in New Hyde Park, N.Y.

“Knowing which bacteria are good and which are bad could lead to preventive treatments or serve as predictors of risk of development of this cancer,” Kelsch said.

Ahn added that good oral health – including regular tooth brushing and dental visits – may help protect against gum disease and health conditions associated with it.

The study findings were published Dec. 1 in the journal Cancer Research.=

Gut Bacteria ‘Boost’ Cancer Therapy

Bacteria living in the murky depths of the digestive system seem to influence whether tumours shrink during cancer therapy, say French and US researchers.

They tested the microbiome – the collection of microscopic species that live in us – in cancer patients.
Two studies, in the journal Science, linked specific species and the overall diversity of the microbiome to the effectiveness of immunotherapy drugs.

Experts said the results were fascinating and held a lot of promise.

Our bodies are home to trillions of micro-organisms and the relationship between “us” and “them” goes far beyond infectious diseases.

The microbiome is involved in digestion, protection from infection and regulating the immune system.

  • Gut bugs ‘help prevent allergies’
  • Parkinson’s disease ‘may start in gut’

Both studies were on patients receiving immunotherapy, which boosts the body’s own defences to fight tumours.

It does not work in every patient, but in some cases it can clear even terminal cancer.

Survival

One study, at the Gustave Roussy Cancer Campus in Paris, looked at 249 patients with lung or kidney cancer.

They showed those who had taken antibiotics, such as for dental infection, damaged their microbiome and were more likely to see tumours grow while on immunotherapy.

One species of bacteria in particular, Akkermansia muciniphila, was in 69% of patients that did respond compared with just a third of those who did not.

Boosting levels of A. muciniphila in mice seemed to also boost their response to immunotherapy.
Meanwhile, at the University of Texas MD Anderson Cancer Center, 112 patients with advanced melanoma had their microbiome analysed.

Those that responded to therapy tended to have a richer, more diverse microbiome than those that did not.

And they had different bacteria too. High levels of Faecalibacterium and Clostridiales appeared to be beneficial, while Bacteroidales species were bad news in the study.

‘Game-changing’

Tissues samples showed there were more cancer-killing immune cells in the tumour of people with the beneficial bacteria.

The team then performed a trans-poo-sion, a transplant of faecal matter, from people to mice with melanoma.

Mice given bacteria from patients with the “good” mix of bacteria had slower-growing tumours than mice given “bad” bacteria.

Dr Jennifer Wargo, from Texas, told the BBC: “If you disrupt a patient’s microbiome you may impair their ability to respond to cancer treatment.”
She is planning clinical trials aimed at altering the microbiome in tandem with cancer treatment.
She said: “Our hypothesis is if we change to a more favourable microbiome, you just may be able to make patients respond better.
“The microbiome is game-changing, not just cancer but for overall health, it’s definitely going to be a major player.”

Promising

Mark Fielder, president of the Society for Applied Microbiology and professor of medical biology at Kingston University, said the study showed the importance of understanding the micro-organisms that call our bodies home.

He told the BBC: “It’s really interesting and holds a lot of promise, we need to do more work but there are exciting glimmers here in treating some difficult diseases.
“Some claim the microbiome is the answer to everything, I don’t think that’s the case.
“But once we understand more, it could be that microbiome manipulation is important in changing people’s health.”

Dr Emma Smith from Cancer Research UK, said: “It’s fascinating.

“One of the big challenges for using immunotherapies to treat cancer is understanding which patients will respond, and this research is a step towards helping doctors to identify these people.”

Garlic: Proven Health Benefits

Garlic (Allium sativum), is used widely as a flavoring in cooking, but it has also been used as a medicine throughout ancient and modern history; it has been taken to prevent and treat a wide range of conditions and diseases.

Garlic belongs to the genus Allium and is closely related to the onion, rakkyo (an onion found in Asia), scallion, chive, leek, and shallot. It has been used by humans for thousands of years and was used in Ancient Egypt for both culinary purposes and its health and therapeutic benefits.

This article will look at the potential health benefits of garlic and cover any research that supports the claims.

In this article:

  1. Garlic for food and medicine – a brief history
  2. Garlic is used widely today for its therapeutic properties
  3. Health benefits of garlic – scientific studies


Fast facts on garlic

  • In many countries, garlic has been used medicinally for centuries.
  • Garlic may have a range of health benefits, both raw and cooked.
  • It may have significant antibiotic properties.

 

Garlic for food and medicine – a brief history

Garlic has been used all over the world for thousands of years. Records indicate that garlic was in use when the Giza pyramids were built, about 5,000 years ago.

Richard S. Rivlin wrote in the Journal of Nutrition that the ancient Greek physician Hippocrates (circa. 460-370 BC), known today as “the father of Western medicine,” prescribed garlic for a wide range of conditions and illnesses. Hippocrates promoted the use of garlic for treating respiratory problems, parasites, poor digestion, and fatigue.

The original Olympic athletes in Ancient Greece were given garlic – possibly the earliest example of “performance enhancing” agents used in sports.

From Ancient Egypt, garlic spread to the advanced ancient civilizations of the Indus Valley (Pakistan and western India today). From there, it made its way to China.

According to experts at Kew Gardens, England’s royal botanical center of excellence, the people of ancient India valued the therapeutic properties of garlic and also thought it to be an aphrodisiac. The upper classes avoided garlic because they despised its strong odor, while monks, “…widows, adolescents, and those who had taken up a vow or were fasting, could not eat garlic because of its stimulant quality.”

Throughout history in the Middle East, East Asia, and Nepal, garlic has been used to treat bronchitis, hypertension (high blood pressure), TB (tuberculosis), liver disorders, dysentery, flatulence, colic, intestinal worms, rheumatism, diabetes, and fevers.

The French, Spanish, and Portuguese introduced garlic to the New World.

Garlic is used widely today for its therapeutic properties

Currently, garlic is widely used for several conditions linked to the blood system and heart, including atherosclerosis (hardening of the arteries), high cholesterol, heart attack, coronary heart disease, and hypertension.

Garlic is also used today by some people for the prevention of lung cancer, prostate cancer, breast cancer, stomach cancer, rectal cancer, and colon cancer.

It is important to add that only some of these uses are backed by research.

A study published in the journal Food and Chemical Toxicology warned that short-term heating reduces the anti-inflammatory effects of fresh raw garlic extracts. This may be a problem for some people who do not like or cannot tolerate the taste and/or odor of fresh garlic.

Health benefits of garlic – scientific studies

Below are examples of some scientific studies published in peer-reviewed academic journals about the therapeutic benefits (or not) of garlic.

Lung cancer risk

People who ate raw garlic at least twice a week during the 7 year study period had a 44 percent lower risk of developing lung cancer, according to a study conducted at the Jiangsu Provincial Center for Disease Control and Prevention in China.

The researchers, who published their study in the journal Cancer Prevention Research, carried out face-to-face interviews with 1,424 lung cancer patients and 4,543 healthy individuals. They were asked about their diet and lifestyle, including questions on smoking and how often they ate garlic.

The study authors wrote: “Protective association between intake of raw garlic and lung cancer has been observed with a dose-response pattern, suggesting that garlic may potentially serve as a chemo-preventive agent for lung cancer.”

Brain cancer

Organo-sulfur compounds found in garlic have been identified as effective in destroying the cells in glioblastomas, a type of deadly brain tumor.

Scientists at the Medical University of South Carolina reported in the journal Cancer that three pure organo-sulfur compounds from garlic – DAS, DADS, and DATS – “demonstrated efficacy in eradicating brain cancer cells, but DATS proved to be the most effective.”

Co-author, Ray Swapan, Ph.D., said “This research highlights the great promise of plant-originated compounds as natural medicine for controlling the malignant growth of human brain tumor cells. More studies are needed in animal models of brain tumors before application of this therapeutic strategy to brain tumor patients.”

Hip osteoarthritis

Women whose diets were rich in allium vegetables had lower levels of osteoarthritis, a team at King’s College London and the University of East Anglia, both in England, reported in the journal BMC Musculoskeletal Disorders. Examples of allium vegetables include garlic, leeks, shallots, onions, and rakkyo.

The study authors said their findings not only highlighted the possible impact of diet on osteoarthritis outcomes but also demonstrated the potential for using compounds that exist in garlic to develop treatments for the condition.

The long-term study, involving more than 1,000 healthy female twins, found that those whose dietary habits included plenty of fruit and vegetables, “particularly alliums such as garlic,” had fewer signs of early osteoarthritis in the hip joint.

Potentially a powerful antibiotic

Diallyl sulfide, a compound in garlic, was 100 times more effective than two popular antibiotics in fighting the Campylobacter bacterium, according to a study published in the Journal of Antimicrobial Chemotherapy.

The Campylobacter bacterium is one of the most common causes of intestinal infections.

Senior author, Dr. Xiaonan Lu, from Washington State University, said, “This work is very exciting to me because it shows that this compound has the potential to reduce disease-causing bacteria in the environment and in our food supply.”

Heart protection

Diallyl trisulfide, a component of garlic oil, helps protect the heart during cardiac surgery and after a heart attack, researchers at Emory University School of Medicine found. They also believe diallyl trisulfide could be used as a treatment for heart failure.

Hydrogen sulfide gas has been shown to protect the heart from damage.

However, it is a volatile compound and difficult to deliver as therapy.

Because of this, the scientists decided to focus on diallyl trisulfide, a garlic oil component, as a safer way to deliver the benefits of hydrogen sulfide to the heart.

In experiments using laboratory mice, the team found that, after a heart attack, the mice that had received diallyl sulfide had 61 percent less heart damage in the area at risk, compared with the untreated mice.

In another study, published in the Journal of Agricultural and Food Chemistry, scientists found that garlic oil may help protect diabetes patients from cardiomyopathy.

Cardiomyopathy is the leading cause of death among diabetes patients. It is a chronic disease of the myocardium (heart muscle), which is abnormally thickened, enlarged, and/or stiffened.

The team fed diabetic laboratory rats either garlic oil or corn oil. Those fed garlic oil experienced significantly more changes associated with protection against heart damage, compared with the animals that were fed corn oil.

The study authors wrote, “In conclusion, garlic oil possesses significant potential for protecting hearts from diabetes-induced cardiomyopathy.”

Human studies will need to be performed to confirm the results of this study.

High cholesterol and high blood pressure

Researchers at Ankara University investigated the effects of garlic extract supplementation on the blood lipid (fat) profile of patients with high blood cholesterol. Their study was published in the Journal of Nutritional Biochemistry.

The study involved 23 volunteers, all with high cholesterol; 13 of them also had high blood pressure. They were divided into two groups:

  • The high-cholesterol normotensive group (normal blood pressure).
  • The high-cholesterol hypertensive group (high blood pressure).

They took garlic extract supplements for 4 months and were regularly checked for blood lipid parameters, as well as kidney and liver function.

At the end of the 4 months, the researchers concluded “…garlic extract supplementation improves blood lipid profile, strengthens blood antioxidant potential, and causes significant reductions in systolic and diastolic blood pressures. It also leads to a decrease in the level of oxidation product (MDA) in the blood samples, which demonstrates reduced oxidation reactions in the body.”

In other words, the garlic extract supplements reduced high cholesterol levels, and also blood pressure in the patients with hypertension. The scientists added that theirs was a small study – more work needs to be carried out.

Prostate cancer

Doctors at the Department of Urology, China-Japan Friendship Hospital, Beijing, China, carried out a study evaluating the relationship between Allium vegetable consumption and prostate cancer risk.

They gathered and analyzed published studies up to May 2013 and reported their findings in the Asian Pacific Journal of Cancer Prevention.

The study authors concluded, “Allium vegetables, especially garlic intake, are related to a decreased risk of prostate cancer.”

The team also commented that because there are not many relevant studies, further well-designed prospective studies should be carried out to confirm their findings.

Alcohol-induced liver injury

Alcohol-induced liver injury is caused by the long-term over-consumption of alcoholic beverages.

Scientists at the Institute of Toxicology, School of Public Health, Shandong University, China, wanted to determine whether diallyl disulfide (DADS), a garlic-derived organosulfur compound, might have protective effects against ethanol-induced oxidative stress.

Their study was published in Biochimica et Biophysica Acta.

The researchers concluded that DADS might help protect against ethanol-induced liver injury.

Preterm (premature) delivery

Microbial infections during pregnancy raise a woman’s risk of preterm delivery. Scientists at the Division of Epidemiology, Norwegian Institute of Public Health, studied what impact foods might have on antimicrobial infections and preterm delivery risk.

The study and its findings were published in the Journal of Nutrition.

Ronny Myhre and colleagues concentrated on the effects of Alliums and dried fruits, because a literature search had identified these two foods as showing the greatest promise for reducing preterm delivery risk.

The team investigated the intake of dried fruit and Alliums among 18,888 women in the Norwegian Mother and Child Cohort, of whom 5 percent (950) underwent spontaneous PTD (preterm delivery).

The study authors concluded, “Intake of food with antimicrobial and prebiotic compounds may be of importance to reduce the risk of spontaneous PTD. In particular, garlic was associated with overall lower risk of spontaneous PTD.”

Garlic and the common cold

A team of researchers from St. Joseph Family Medicine Residency, Indiana, carried out a study titled “Treatment of the Common Cold in Children and Adults,” published in American Family Physician.

They reported that “Prophylactic use of garlic may decrease the frequency of colds in adults, but has no effect on duration of symptoms.” Prophylactic use means using it regularly to prevent disease.

Though there is some research to suggest that raw garlic has the most benefits, other studies have looked at overall allium intake, both raw and cooked, and have found benefits. Therefore, you can enjoy garlic in a variety of ways to reap its advantages.
