Can Green Tea Help Prevent Alzheimer’s Disease?

Green tea is touted as an amazing superfood replete with many healing benefits, from its anti-cancer properties to its heart health boosting compounds. So it is no surprise that green tea has been linked with the prevention of Alzheimer’s disease. But new research found that it may offer more protection than originally believed.

Green tea is high in antioxidants that fight off harmful free radicals. By some estimates the antioxidants found in green tea may be 20 times more potent than vitamin E, which is a proven brain health booster. But new research shows that green tea is even better than just its amazing antioxidants.

According to a new study by scientists at McMaster University in Hamilton, Canada, and published in the Journal of the American Chemical Society found that epigallocatechin gallate (EGCG) has yet another health benefit—it stops beta amyloid plaques linked to Alzheimer’s from forming. Beta amyloid plaques have long been known as causal factors in Alzheimer’s but finding ways to stop the harmful plaques from forming has been the task of many researchers. Beta amyloid plaques disrupt communication between brain and nerve cells, creating the memory loss and dementia, which are the trademark signs of Alzheimer’s disease.

This new research found that EGCG in green tea effectively prevented plaques from being able to damage healthy cells. While the exact mechanism by which EGCG achieves this protection is not fully clear, the discovery is an exciting one into brain health and Alzheimer’s disease.

This ground-breaking research offers hope to the 50 million people worldwide who already suffer from Alzheimer’s disease since EGCG may slow the plaque’s progression and therefore the disease’s progression as well. It may also help anyone looking to prevent the disease, which is probably most people.

This research supports earlier research in the medical journal Brain Research that also found that green tea consumption can help prevent Alzheimer’s disease. Other research in the American Journal of Medicine found that regular tea consumption can cut the risk of cognitive decline in half, which is impressive by anyone’s standards.

While the research is still quite early so it is not clear exactly how much green tea or its protective compound EGCG is needed to reap the brain protective effects, most experts agree that a few cups of green tea daily should be helpful with brain health. Earlier research published in the American Journal of Epidemiology found that people who drank two or more cups of tea each day were less likely to develop Parkinson’s disease. The benefits were not linked to tea’s caffeine content which is lower than the caffeine found in coffee.

To make green tea: add one or two teaspoons of green tea leaves to a cup of boiled water, preferably in a tea strainer. Let steep for five minutes. Pour over ice if you prefer a cold beverage.  And don’t worry—it contains a lot less caffeine than coffee or black tea. Green tea contains about 55 mg of caffeine per cup while coffee typically contains between 125 and 200 mg per cup.

If you’re not a big fan of the taste of green tea, try it blended with other types of tea, such as ginger or lemongrass. You can also try icing it with some stevia to sweeten the beverage and a squeeze of fresh lemon juice for a delicious green tea lemonade.

You Say Turmeric, I Say Curcumin

Either way, we say healthy

Who doesn’t love the flavours and aromas that turmeric imbues our lives with? But we can also thank this delicious spice for some powerful therapeutic properties. Find out what this yellow jewel can do for you.

If you’ve eaten curry, you’ve likely consumed turmeric. Not only does this spice lend its flavour and yellow colour to delicious curry dishes; it’s also played an important role in ancient medical practices like Ayurveda and traditional Chinese medicine.

Curcumin, found in supplement form at your natural health store, is the active ingredient of the turmeric plant. Over the last few decades, the extract curcumin has been the subject of wide-ranging scientific research for its medicinal properties.

The colour of health may be yellow

Prized for its yellow hue and medicinal properties for, reportedly, 4,000 years, turmeric’s unique qualities are found in its curcuminoid components. Extracted from the turmeric (Curcumin longa L.) plant, curcumin research has uncovered plenty of reason to turn (to) yellow.

Burns and scalds

While you’re in the kitchen cooking up a batch of your favourite curry, you may have occasion to remember that the curcumin in that turmeric you’ve just added to the pan is also useful in a gel to help heal minor burns and scalds.

Research says:

The effectiveness of curcumin gel on the skin is, according to the author of a recent study, related to its powerful anti-inflammatory properties. Research subjects who were treated with a topical curcumin gel after suffering minor burns had less pain and inflammation and improved healing with less than expected scarring—even no scarring in some cases.

Arthritis pain

People who suffer from joint pain and swelling from arthritis, either from osteoarthritis or rheumatoid arthritis, may be able to find some relief with curcumin’s ability to reduce inflammation. And it may help them get around much more easily.

Research says:

Clinical studies have shown a positive effect of curcumin on reducing pain and improving physical function and quality of life for osteoarthritis patients through its anti-inflammatory and cartilage-protective qualities. Preliminary evidence suggests that curcumin may also have the same effect for people with rheumatoid arthritis.

Cancer

In countries where people eat curcumin at levels of about 100 mg to 200 mg a day over long periods of time, there are low rates of certain types of cancer. Curcumin seems to have a powerful effect on cancer cells. In some cases curcumin has shown the ability to step in and reduce the ability of cancer cells to transform, grow, and spread to other parts of the body.

Research says:

The promising results in laboratory studies have inspired researchers all over the world to continue the search for the exact mechanism by which curcumin could help prevent and even offer therapeutic benefits for certain types of cancer. Researchers, in a recent review of years of curcumin studies, suggest that future studies should take a more holistic approach to account for turmeric’s chemically diverse constituents that may synergistically contribute to its potential benefits.

Ulcerative colitis

There is currently no known cure for ulcerative colitis, an inflammatory bowel disease that affects the lining of the large intestine (colon) and rectum. One of the goals of treatment is to prevent relapses of its symptoms and promote remission. This is something that curcumin seems to be able to help with.

Research says:

A Cochrane Database systematic review of studies into curcumin’s effectiveness for maintenance of remission in patients with ulcerative colitis (UC) in 2014 concluded that curcumin may be a safe and effective adjunctive therapy for maintenance of remission in “quiescent” UC.

Alzheimer’s disease?

Elderly villagers in India, where turmeric is a dietary staple, have the lowest rate of Alzheimer’s disease in the world; and researchers have been keen to determine if curcumin may play a role in this. They were intrigued because of curcumin’s antioxidant and anti-inflammatory properties.

Research says:

Though plenty of studies have focused on exploring this possibility, so far there’s no concrete evidence that curcumin is effective in combatting or preventing Alzheimer’s disease. The research continues, though, since laboratory studies have shown some intriguing and promising possibilities.

How To Beat Alzheimer’s: Neurologists Devise A Plan To Protect Yourself And Even Reverse Early Symptoms

How To Beat Alzheimer’s: Neurologists Devise A Plan To
Protect Yourself And Even Reverse Early Symptoms

As a high-powered lawyer at the top of her game, Evelyne had always been efficient, authoritative and in control.

But when she reached 60, she reluctantly began to accept that her mind wasn’t as sharp as it once had been.

She found herself increasingly confounded by a nagging sense of confusion and exhaustion — and started second-guessing some of her decisions.

But when Evelyne found herself going completely blank in the middle of an important presentation, she knew something was very wrong.

Evelyne is typical of the thousands of patients we have seen over the course of the 20 years we have spent studying Alzheimer’s disease.

As a neurologist husband-and-wife team, together we run the prestigious Memory and Ageing Centre at Loma Linda University in California — a hospital that is dedicated to cutting-edge research into the condition.

As doctors at the very peak of our profession, we have worked at some of the world’s leading hospitals and have dedicated our careers to finding a cure for this devastating disease.

While other chronic conditions such as heart disease, diabetes, cancer and strokes are in decline, cases of Alzheimer’s disease are rising.

It’s now the leading cause of death in the UK — overtaking heart disease in 2016. Indeed, for many of us the question is no longer if we will get the disease, but when.

Today, women over 60 in the UK are twice as likely to get dementia as breast cancer, and the risk of developing it doubles every five years after the age of 65.

By 2025, there will be more than one million people in the UK with dementia.

But now, thanks to years of exhaustive research, we firmly believe we have found a scientifically backed way to reduce your risk and keeping your brain sharper for longer.

Our method could even help to reduce some of the symptoms of dementia after it has started to develop.

The key is a personalised lifestyle plan, which we’ve called the Alzheimer’s Solution — the name of our books.

It identifies your individual risk of getting the disease and then helps you to minimise these risks through simple tweaks to your lifestyle.

Our plan focuses on five key areas that can really make a difference: diet, exercise, sleep, stress and brain training (exercises shown to help boost the brain, such as Sudoku or learning a language).

Throughout our careers we’ve treated thousands of patients and helped them to reverse some of the symptoms of dementia and added years to their lives.

Take Evelyne. Just two months after her first visit to us, tests showed that her short-term memory had improved by 30 per cent and her attention score by 50 per cent.

In a very short space of time, she was seeing a reversal of some of her symptoms.

So how does our plan actually work?

When we started on this quest for an Alzheimer’s cure, we assumed any solution would come in the form of a pill.

But after conducting one of the most comprehensive reviews ever into scientific studies that show the causes of dementia, we are convinced that many cases can be put down to a poor diet consisting of heavily processed food — with an emphasis on sugar and meat — combined with a sedentary, sleep-deprived and stressful lifestyle.

What’s more, the data we looked at (which comprised thousands of studies) convinced us that lifestyle changes that are beneficial to the heart and kidneys also appear to be beneficial to the brain.

That’s why our Alzheimer’s Solution works. It draws on 15 years’ worth of published research from around the globe.

We’ve guided thousands of people through the highly personalised process of lifestyle change throughout our careers — and the overall effects have been profound.

Jerry, for example, came to us with an early diagnosis of vascular dementia, desperate for a solution. We looked in detail at his lifestyle — and then prescribed exercise.

He started pedalling very gently on a stationary bike in front of his TV each day and saw immediate improvements in his mood and memory.

This spurred him on to make further lifestyle adjustments. He decided to take steps to improve his sleep, diet and stress levels — and within a year, a scan of his brain showed rather profound improvements.

‘I was stuck in a parallel universe,’ he told us. ‘But now I’m back with everyone else.’

He is proof that our plan works. And to say these findings changed the course of our lives as doctors would be a complete understatement.

Our discoveries have wholly altered the way that we think about dementia, cognitive health and the future of Alzheimer’s treatment.

There may still be no cure for Alzheimer’s but, with the right advice, we can be mentally active for longer, reverse the debilitating symptoms of the disease and ultimately add more happy, healthy years to our lives.

The best part is that our plan is so simple you can make immediate changes in the sure knowledge that you are launching your own personal fight against Alzheimer’s disease.

1. We found that eating meat is bad for your brain, which requires vegetables, fruit, pulses, grains and healthy fats to thrive.

We therefore recommend a plant-based diet low in sugar, salt and processed foods.

2. Physical exercise increases both the number of brain cells and the connections between them. We suggest maintaining an active lifestyle that incorporates movement every hour — not just a quick stop at the gym after an otherwise sedentary day at the office, for example.

3. Chronic stress puts the brain in a state of high inflammation, causing structural damage and impairing its ability to clear toxins. We recommend meditation, yoga, breathing exercises and time outside.

4. Restorative sleep is essential for health so it’s important to aim for seven to eight hours a night.

5. Puzzles and other complex activities protect your brain against decline.

Social support and engagement with your community can also have a clear and undeniable influence on the way in which your brain ages.

And activities such as playing music are great for challenging and engaging many of the brain’s capacities.

Health Tip Tuesday

Neurobics for your mind. Get your brain fizzing with energy. American researchers coined the term ‘neurobics’ for tasks which activate the brain’s own biochemical pathways and to bring new pathways online that can help to strengthen or preserve brain circuits.

Brush your teeth with your ‘other’ hand, take a new route to work or choose your clothes based on sense of touch rather than sight. People with mental agility tend to have lower rates of Alzheimer’s disease and age-related mental decline.

Can Gut Bacteria Affect Alzheimer’s Disease?

New research finds the microbes in your gut may play a major role in escalating the chronic brain disease.

A raft of recent studies has shown that the microbiome is a factor in the development of obesity, type 2 diabetes, asthma, and cardiovascular disease. Now, we can add Alzheimer’s disease to the list.

A new study, published in Scientific Reports, has shown that certain gut microbiota may speed up the development of the chronic brain disease.

Researchers studied both healthy and diseased mice and found that those with Alzheimer’s had a different composition of gut bacterium. Healthy mice also had a lower level of beta-amyloid plaque in their brains than the mice with Alzheimer’s. (Beta-amyloid plaques are the lumps of protein fragments that form at nerve fibers, creating tangles leading to neuroinflammation.)

To further test the connection between intestinal flora and Alzheimer’s disease, researchers placed microbes from mice suffering from Alzheimer’s into germ-free mice. The result? The germ-free mice given the gut microbes from the mice with Alzheimer’s developed more beta-amyloid brain plaques than those who received bacteria from healthy mice.

“The results mean that we can now begin researching ways to prevent the disease and delay the onset,” researcher Frida Fåk Hållenius, PhD, of Sweden’s Lund University Food for Health Science Centre, says in a press release. “We consider this to be a major breakthrough as we used to only be able to give symptom-relieving antiretroviral drugs.”

‘TAKE CARE OF YOUR MICROBIOME, IT’LL TAKE CARE OF YOU’
The findings open the door to testing new preventive and therapeutic strategies — such as dietary modification — on bacteria’s role in Alzheimer’s disease development.

In November 2016, for example, Iranian researchers found that probiotics helped improve memory in people suffering from severe Alzheimer’s disease. Although the sample size was small (60 participants) and the study lasted only 12 weeks, the results indicate that eating microbiome-boosting foods may improve memory in those who are cognitively impaired.

“If you take care of your microbiome, it’ll take care of you — and that’s all the way up to your brain,” says leading Alzheimer’s researcher Rudolph Tanzi, PhD.

To reduce your Alzheimer’s risk, Tanzi advises avoiding eating processed and other inflammation-promoting foods, which negatively affect gut microbial communities, and focusing on real food.

This Type of Exercise May Guard Against Dementia

People who worked out on a bike, a treadmill, or the elliptical showed improvement in their memory and problem solving skills after six months, a new study found.

Working out is good for you in more ways than we can count, but a new study may have uncovered a new perk for people with memory problems.

Researchers from the Wake Forest School of Medicine found that aerobic exercise appears to boost thinking skills and brain volume in adults diagnosed with mild cognitive impairment, a condition that sits in between normal age-related memory decline and more serious dementia. Stretching routines also increased brain volume over a six-month period, but had no noticeable impact on brain function.

The study was presented today at an annual meeting of radiologists in Chicago, and hasn’t yet been peer-reviewed or published.

Researchers used a new MRI technique to measure both volume and shape changes in specific areas of the brain, which are both important indicators for tracking the development of dementia.

At the start of the study, the researchers performed MRI scans on 35 people with mild cognitive impairment, which is a risk factor for Alzheimer’s disease. The participants were then divided into two groups and assigned to four weekly sessions of either stretching exercises or aerobic activity—walking on a treadmill, cycling on a stationary bike, or training on an elliptical machine. After six months, the researchers did a second MRI scan and compared the two sets of scans.

Both groups showed increases in most gray matter regions of the brain, including the temporal lobe, which supports short-term memory. But those increases were greater in the group that walked, pedaled, or spent time on the elliptical.

“Even over a short period of time, we saw aerobic exercise lead to a remarkable change in the brain,” said lead investigator Laura D. Baker, PhD, associate professor of gerontology and geriatric medicine at Wake Forest, in a press release.

People in the stretching group had less total brain volume increase, and their brain scans also showed signs of “directional deformation”—shape changes possibly related to volume loss—within the brain’s white matter. The researchers believe these hard-to-detect signs could be early indicators of dementia. “Directional changes in the brain without local volume changes could be a novel biomarker for neurological disease,” co-author Jeongchul Kim, PhD, said in a press release.

In an abstract presented at the conference, the researchers concluded that aerobic exercise “could preserve or possibly even improve brain volumes” in people with early cognitive problems.

What’s more, the researchers also reported that over a six-month period, participants in the aerobic exercise group improved in tests that measure executive function—a set of thinking processes that include working memory, reasoning, and problem solving—while the stretching group showed no change.

That doesn’t mean stretching didn’t help in some way, the authors say, especially when compared to completely sedentary behavior. It does suggest, however, that aerobic activity may be a better bet for overall brain functioning.

Plenty of previous research has tied exercise to better brain outcomes in older adults; a 2014 Canadian study, for example, found that brisk walking (but not resistance training, balance exercises, or muscle toning) was associated with enlargement of the hippocampus. Aerobic exercise may have some competition when it comes to brain health, however. Last month, an Australian study found that women who lifted weights regularly had better cognitive function than those who did regular stretching and calisthenics.

This newest study, although small and preliminary, is in line with previous research suggesting that “any type of exercise can be beneficial,” said Kim—good news for older adults who perhaps can’t get out and walk, ride, or otherwise break a sweat. However, he added, “If possible, aerobic activity may create potential benefits for higher cognitive functioning.”

Keep Busy! Stay Sharp!

Study suggests a full schedule may enhance your mental prowess

By Amy Norton    HealthDay Reporter   WebMD News from HealthDay

TUESDAY, May 17, 2016 (HealthDay News) – Although people complain when their schedule gets too busy, new research suggests that being overbooked might actually be good for the brain.

The study of older adults found that those with packed schedules tended to do better on tests of memory, information processing and reasoning.

Researchers said the findings don’t prove that “busyness” makes us smarter. For one, sharper people may seek out more mental stimulation. These people may also have more resources, such as higher incomes, that allow them to lead active lives.

On the other hand, past research has found that learning new skills can improve older adults’ overall mental acuity, said study leader Sara Festini.

“We think it is likely that being busy is good for your cognition,” said Festini, a researcher with the Center for Vital Longevity at the University of Texas at Dallas.

She and her colleagues reported the findings in the May 17 online issue of Frontiers in Aging Neuroscience.

The results are in line with those from many previous studies, the researchers said.

Past research has found that older adults who are more active — mentally, physically or socially — tend to have better mental function and a lower risk of dementia. In fact, the Alzheimer’s Association recommends all three types of activity for maintaining better brain health.

According to Festini, busyness could be a proxy for people’s “cognitive engagement” in daily life.

For the study, she and her colleagues had 330 men and women rate their “busyness” levels — asking questions such as, “How often do you have too many things to do each day to actually get them all done?” The study volunteers were between 50 and 89 years old.

The researchers also gave the volunteers a battery of tests that gauged memory, information processing speed, reasoning and vocabulary.

Overall, the study found, the busier people were in their daily lives, the better their test performance — especially when it came to remembering specific events from the past. The findings were not explained by age or education level.

Still, there are other potential explanations for the connection, said Debra Fleischman, a professor of neurological and behavioral sciences at Rush University Medical Center, in Chicago.

“Occupation, income, ethnicity and race are all important factors that can influence accessibility to resources that support an active lifestyle,” said Fleischman, who wasn’t involved in the study.

Plus, she added, people’s health – physical and mental – could affect both their daily activities and their scores on tests of memory and thinking (“cognition”).

Festini said she was interested in studying the subject because people often talk about their tight schedules, but there’s little research on how our “busyness” relates to health.

On one hand, a packed schedule could cause unhealthy levels of stress; on the other, busy people may have more “effortful engagement” with life, the researchers suggested.

According to Fleischman, it would be interesting to know whether the busy study participants were stressed out by their schedules. And that, she noted, could vary by age.

Older adults might tend to see a hectic schedule as a good thing – a sign that they have purpose in life, Fleischman said. But, she added, it’s possible that younger people could view busyness in a more negative light.

The current findings say nothing about the types of activities that are related to sharper mental skills, Fleischman pointed out. But past studies have already shown there may be benefits from physical exercise, mental tasks — such as crossword puzzles and reading — and social activities, she said.

“Daily activity is important to promote cognitive health in people over age 50,” Fleischman said.
Festini agreed. “[This study] provides further motivation to seek out additional activities and to keep learning new skills throughout adulthood,” she said.
