This Nutrient Balance Reverses Brain Aging

The right balance between omega-3 and omega-6 fatty acids may help promote healthy cognitive aging, new research finds.

While we are used to hearing about the benefits of the fatty acids in fish and fish oils, that is only half the story.

Omega-6 fatty acids can come from nuts, seeds and other oils.

Typically, Western diets have too much omega-6 and not enough omega-3.

Together, a balance of these fatty acids may help to reduce age-related decline and maintain the integrity of cortical structures.

Ms Marta Zamroziewicz, who led the research, said:

“We studied a primary network of the brain — the frontoparietal network — that plays an important role in fluid intelligence and also declines early, even in healthy aging.
In a separate study, we examined the white matter structure of the fornix, a group of nerve fibers at the center of the brain that is important for memory.”

The researchers examined the levels of polyunsaturated fatty acids in adults aged 65 to 75, along with their brain structure.

The best balance of fatty acids for brain health.

Ms Zamroziewicz explained that it takes more than just fish and fish oils to keep the brain healthy with age:

“A lot of research tells us that people need to be eating fish and fish oil to get neuroprotective effects from these particular fats, but this new finding suggests that even the fats that we get from nuts, seeds and oils can also make a difference in the brain.”

A second study found a link between a balanced amount of omega-3 and omega-6 fatty acids and greater memory preservation in older adults.

Ms Zamroziewicz explained:

“These findings have important implications for the Western diet, which tends to be misbalanced with high amounts of omega-6 fatty acids and low amounts of omega-3 fatty acids.”

Professor Aron Barbey, who co-authored the study, said:

“These two studies highlight the importance of investigating the effects of groups of nutrients together, rather than focusing on one at a time.
They suggest that different patterns of polyunsaturated fats promote specific aspects of cognition by strengthening the underlying neural circuits that are vulnerable to disease and age-related decline.”

The study was published in the journal Nutritional Neuroscience (Zamroziewicz et al., 2017).

8 Healthy Ways to Boost Energy

Your food and beverage choices can have a big effect on your energy levels throughout the day, an expert says.

As our energy levels decrease because of our overstressed lifestyles, many people look for a quick fix to combat fatigue.

Energy drinks mask the symptoms of fatigue and dehydrate the body. The majority of energy drinks contain excess sugar, high levels of caffeine and other stimulants.

Relying on caffeine and energy drinks makes us feel worse in the long run by causing our system to crash.

Continued fatigue decreases the immune system, making us more susceptible to depression and illness.

So what to do? Exercise, sleep and reducing stress are important in fighting fatigue. But our eating habits also directly affect energy levels. And nutrition can affect energy levels throughout the day.

Here are some tips on healthy ways to boost your energy:

Drink water

The body needs water – multiple glasses a day.

Being hydrated is an easy and inexpensive way to increase energy levels. You don’t need vitamin water or sports drinks; they only add extra unneeded calories. Keep a fresh water source with you at all times and drink throughout the day. Add lemons, limes or oranges for taste variety.

Eat breakfast

This is the meal that sets the stage for the entire day. Studies show that breakfast helps keep you alert, starts your metabolism for the day and keeps you satisfied until lunch.

But a healthy breakfast is the key. Good options include whole-grain cereals, breads, fruit and lean protein instead of doughnuts, pastries and white breads. A hard-boiled egg sliced into a whole wheat pita, oatmeal with fruit, and whole-grain toast with natural peanut butter are all healthy choices.

Don’t forget protein

Not consuming enough protein during the day can be a primary reason for fatigue. Protein-based foods provide the body with fuel to repair and build tissues. Protein takes longer than carbohydrates to break down in the body, providing a longer-lasting energy source. You can find protein in poultry, fish, lean red meat, nuts, milk, yogurt, eggs, yogurt, cheese and tofu.

Keep your carbs smart

Carbohydrates are the body’s preferred source of fuel. Pick whole grains like cereal, brown rice and whole wheat bread, and avoid sweets, which cause energy to plummet. Many processed carbohydrates contain little to no fiber. Always read the nutrition label.

Snacks are important

If you let yourself get too hungry between meals, your blood sugar falls, and you get lethargic. Keep your blood sugar and energy level steady during the day by consuming snacks. Choosing the right snacks prevent peaks and valleys in energy.

Combine complex carbs with a protein and/or fat for lasting energy. The protein and fat slow the breakdown of sugar into the blood, preventing fatigue. Snacks also can prevent overeating at mealtimes. A few examples of smart snack choices are yogurt with fruit, mixed nuts, veggies with hummus, pears with almond butter, whey protein shake or blueberries with a cheese stick. Plan ahead!

Omega-3 fatty acids

Studies have shown that omega-3 fatty acids reduce inflammation, combat depression and improve mood and memory. Try to focus on omega-3 fats from food rather than supplements. Excellent sources include salmon, tuna, walnuts, flax seeds, leafy greens and hemp seeds.

Magnesium

Almonds, walnuts and Brazil nuts are rich in magnesium, a mineral important in converting carbohydrates into energy. Other good sources of magnesium include whole grains and dark green vegetables.

Don’t skimp on calories

Skimping on calories decreases your metabolism and causes you to feel lethargic. Keep your energy levels high and increase metabolism by meeting your caloric needs each day. Whole foods are preferred over supplements to obtain protein, fiber, vitamins and minerals instead of one or two single nutrients. Consume a variety of foods for overall health but also to keep your energy levels high.

7 Nutrients Your Brain Needs To Stay Young

Perhaps you remember hearing your parents or some other authority figures telling you that fish is brain food. What they meant was that fish contains nutrients called omega-3 fatty acids that have been shown to enhance or improve brain function and help it to stay young.

For those of you who don’t care for fish or who don’t consume animal products, there are various supplements you can take to get your omega-3s. But omega-3s are not the only good brain nutrients; there are numerous others that can help your brain stay young and a wide variety of foods in which to find them. For example, the B vitamins (aka, B-complex) are a group of nutrients that work in sync to support and promote brain health.

In fact, the brain needs a constant supply of nutrients to support optimal function, from energy metabolism for its billions of neurons to the synthesis of neurotransmitters, propagation of nerve impulses, and other brain activities.

Here we look beyond the B vitamins to omega-3s and six other nutrients that your brain needs to stay young and functioning at an optimal level. These nutrients, along with a diet rich in these nutrients, regular exercise, avoidance of smoking, stress management, and sufficient sleep all have a role in maintaining a healthy brain.

Omega-3 fatty acids

According to researchers, omega-3 fatty acids have demonstrated an ability to improve cognitive function. A 2017 Brazilian systematic review, for example, found that omega-3 fatty acid supplements in mild Alzheimer’s disease may be helpful when there is slight brain function impairment. A mouse study reported that animals given omega-3 supplements demonstrated an improvement in cognitive function (i.e., object recognition memory, localized and spatial memory) as they got older.

In addition to cold water fish, omega-3 fatty acids are also found in walnuts, chia seeds, flax seeds, hemp seeds, and sea vegetables. Omega-3 supplements are available as fish oil, krill oil, and algae-based.

Cocoa flavanols

Dark chocolate is the source of brain-friendly phytonutrients called cocoa flavanols. In a three-month study, researchers discovered that individuals who consumed a high cocoa flavanol diet showed a boost in the area of the brain associated with memory loss and aging.

Cocoa powder is made by fermenting, drying and roasting cacao beans. The flavanols have been shown to lower blood pressure, fight cell damage, prevent blood clots, and improve blood flow to the brain.

To reap the brain-boosting benefits of cocoa flavanols, choose dark chocolate (organic preferred) and enjoy a small amount (about one ounce) several times a week or even daily. A 2012 study of adults with mild cognitive impairment showed that those who consumed cocoa flavanols daily benefits from improved thinking skills as well as lower blood pressure and improved insulin resistance.

Magnesium

The mineral that is associated with more than 300 biochemical activities in the human body plays a key role in cognitive health. Low levels of magnesium have been proposed as having a stake in the development of Alzheimer’s disease, but further research is needed. We know from mouse research that an increase in magnesium in the brain provides substantial protection of the synapses in models of Alzheimer’s disease and “hence it might have therapeutic potential for treating Alzheimer’s disease.”

Be sure to include lots of foods rich in magnesium in your diet, including green leafy vegetables, cruciferous vegetables, nuts, and whole grains.

 

Anthocyanins

You may recognize these antioxidants as being especially plentiful in blueberries, but others berries harbor them as well. Anthocyanins are associated with enhanced signalling of neurons in the brain’s memory regions. In one study, adults who consumed wild blueberry juice daily showed improvements in memory; namely, word list recall and paired associate learning, as well as reduced depressive symptoms and glucose levels, both of which can have a negative impact on cognitive function.

In a 2017 study, experts showed that daily blueberry consumption for six weeks by adults with cognitive decline was associated with an improvement in neural response. In addition to blueberries, you can include other foods that provide a good amount of anthocyanins, such as cranberries, black raspberries, blackberries, cherries, eggplant, black rice, red cabbage and muscadine grapes.

EGCG and theanine

The one food that nearly exclusively contains these two ingredients—epigallocatechin gallate and L-theanine–is green tea (Camilla sinensis). Although there are more than 700 compounds in green tea, EGCG and theanine are the ones responsible for improving brain health. Traces of EGCG are also found in apples, carob powder, hazelnuts, onions, pecans, and plums.

EGCG is a potent antioxidant that can pass through the blood-brain barrier and address the free radicals that can destroy brain cells. This polyphenol also has anti-inflammatory powers, which is critical since free radicals trigger brain inflammation, which in turn speeds up brain aging and contributes to memory loss, depression, and anxiety.

The impact of the amino acid L-theanine on cognition also has been shown in various studies. A review of 49 human intervention studies showed that L-theanine has “clear beneficial effects on sustained attention, memory, and suppression of distraction.” The only food sources of L-theanine are black and green teas.

Phosphatidylcholine

This mouthful of a compound is a source of the dietary nutrient choline, which is a member of the B-complex family. Recent research involving phosphatidylcholine explored its impact on brain structure in 72 healthy older adults. The researchers found that higher blood levels of phosphatidylcholine was linked to improved cognitive flexibility.

Although the exact ways phosphatidylcholine benefits the brain and cognitive function are not fully understood, experts suggest it may that the nutrient supports brain membranes, contributes to the production of neurotransmitters that promote and support cognition, or reduce inflammation in the brain. In any event, dietary sources of phosphatidylcholine include egg yolks, raw organic dairy, wheat germ, cruciferous vegetables, and meat.

Be sure to add a lot of these foods to your diet every day to keep your brain young.

Five Foods That May Increase Your IQ

A healthy diet as you’re growing up may help you have a higher IQ, while a diet high in processed foods, fat and sugar may result in a lower IQ, according to a study published in the Journal of Epidemiology & Community Health in February 2011. Many of the same foods typically recommended for a healthy diet may also be good for your IQ.

Fish and Omega-3 Sources

Omega-3 fats, found in many types of fish and seafood, walnuts and flaxseeds, are important for infant brain development. An article published on the Association for Psychological Science website notes that children given omega-3 fats have higher IQs than those who don’t consume much of these essential polyunsaturated fats. These healthy fats may also help protect against dementia as you get older. Oysters are also a good seafood choice, because they’re rich in zinc. Zinc deficiency may adversely affect brain development, according to a review article published in Frontiers in Human Neuroscience in 2013.

Children and pregnant women are particularly sensitive to contaminants in fish, so choose those that are high in omega-3 fats but low in contaminants, such as wild salmon, sardines, Atlantic mackerel, mussels and rainbow trout for the recommended two servings per week of seafood to maximize benefits while minimizing risks.

Fruits and Vegetables

Antioxidant-rich fruits and vegetables, such as leafy greens and orange and red fruits and vegetables, may help protect your brain function and your memory as you age because of the beta-carotene and vitamin C they contain.

A diet rich in herbs, legumes, raw fruits and vegetables and cheese resulted in a higher IQ in children than a diet that included higher amounts of sweet and salty snacks, according to a study published in the European Journal of Epidemiology in July 2012.

Another study, published in the Journal of Child Psychology and Psychiatry in 2009, came to a similar conclusion, showing that children who ate higher amounts of fruits, vegetables and home-prepared foods had higher IQs.

Iron-Rich Foods

Iron-deficiency anemia may impair your attention span, IQ and ability to concentrate, so eat plenty of iron-rich foods. Increasing iron intake only appears to help IQ when children are deficient in iron, however, according to the Frontiers in Human Neuroscience article. Iron-rich foods include lean meats, oysters, beans, tofu, spinach, sardines and fortified breakfast cereals.

Other Protein-Rich Foods

Diets higher in protein and lower in fat may help improve your concentration because of the dopamine your body releases with protein consumption. Soy protein may be particularly helpful, since it also contains lecithin, which may improve memory and brain function. Lowfat dairy products, lean meats and poultry, eggs, nuts, seeds and legumes are all nutritious sources of protein.

Get Plenty of B Vitamins and Choline

Foods containing folate, vitamin B-12 and choline may also help keep your brain healthy, limiting your risk for dementia, depression and neurological disorders. They are also important for cognitive development, so if children don’t get enough of these vitamins they may have a lower IQ. Folate is available in fortified breakfast cereals, spinach, beef liver, rice, asparagus, black-eyed peas, Brussels sprouts and avocado, and most animal-based foods contain vitamin B-12. Good sources of choline include beef, eggs, scallops, salmon, chicken breast, cod, shrimp, Brussels sprouts and broccoli.

How to Naturally Increase Testosterone in Men

Testosterone is a hormone that is secreted in both men and women. It is responsible for sex drive, as well as protein processing for muscle mass development and strength. Testosterone declines with age, illness and poor nutrition in both genders, though this change may be more marked in men. Synthetic hormone replacement therapy can cause adverse side effects. A natural way to raise the body’s testosterone levels safely include supplementing the diet with specific nutrients and physical exercise.

Step 1

Take a B-complex vitamin supplement that includes folic acid, vitamin B5, vitamin B6 and vitamin B12 to increase testosterone production. These nutrients are important in protein and fat metabolism for the manufacture of this hormone. Eat foods that contain these vitamins, including avocados, eggs, fish and wheat germ.

Step 2

Increase the mineral zinc in your diet to raise testosterone levels and sperm production in the body. Take a daily zinc supplement according to the dosage on the label. Eat foods like shellfish, prawns and oysters that are high in this mineral.

Step 3

Take a 500 mg of fish oil once or twice every day, as recommended by your doctor. Fish oil contains omega 3 fatty acids and other nutrients which help to decrease sex hormone binding globulin, or SHBG. SHBG is a protein that captures or binds to testosterone in the blood, lowering availability of the hormone.

Step 4

Get regular strenuous exercise, such as resistance training, weight lifting and endurance running to increase testosterone levels. Decreasing excess body fat helps to decrease estrogen and raise testosterone production in men. As little as 20 minutes of physical activity, four times a week can improve hormone production.

Step 5

Eat foods that increase testosterone production. These include eggs, tomatoes, red peppers, cruciferous vegetables, alfalfa sprouts, apples and pineapples.

Step 6

Reduce saturated fat, sugary and processed foods from your diet. These foods reduce testosterone levels in the body, leading to low libido, loss of muscle mass and other effects.
Warnings

Lower than normal levels of testosterone production may be an indication of a disorder. If levels of this male hormone do not improve with natural methods, a blood test by your doctor can help determine whether there is an underlying cause.

Additionally, fish oil and other supplements may not be beneficial in all cases.

Tips

Ensure that you get adequate restful sleep each night. Sleeping less than the recommended 6 to 8 hours per night increases stress hormones, which lowers testosterone production. Additionally, learn to manage stress levels in healthy ways to naturally increase testosterone. Hormone replacement therapy may be required for some men with low testosterone levels. Consult your physician about treatment options.

Nutritional Strategies to Ease Anxiety

According the National Institute of Mental Health, anxiety disorders are the most common mental illness in the United States. That’s 40 million adults—18% of the population—who struggle with anxiety. Anxiety and depression often go hand in hand, with about half of those with depression also experiencing anxiety.

Specific therapies and medications can help relieve the burden of anxiety, yet only about a third of people suffering from this condition seek treatment. In my practice, part of what I discuss when explaining treatment options is the important role of diet in helping to manage anxiety.

In addition to healthy guidelines such as eating a balanced diet, drinking enough water to stay hydrated, and limiting or avoiding alcohol and caffeine, there are many other dietary considerations that can help relieve anxiety. For example, complex carbohydrates are metabolized more slowly and therefore help maintain a more even blood sugar level, which creates a calmer feeling.

A diet rich in whole grains, vegetables, and fruits is a healthier option than eating a lot of simple carbohydrates found in processed foods. When you eat is also important. Don’t skip meals. Doing so may result in drops in blood sugar that cause you to feel jittery, which may worsen underlying anxiety.

The gut-brain axis is also very important, since a large percentage (about 95%) of serotonin receptors are found in the lining of the gut. Research is examining the potential of probiotics for treating both anxiety and depression.

Foods that can help quell anxiety

You might be surprised to learn that specific foods have been shown to reduce anxiety.

  • In mice, diets low in magnesium were found to increase anxiety-related behaviors. Foods naturally rich in magnesium may therefore help a person to feel calmer. Examples include leafy greens such as spinach and Swiss chard. Other sources include legumes, nuts, seeds, and whole grains.
  • Foods rich in zinc such as oysters, cashews, liver, beef, and egg yolks have been linked to lowered anxiety.
  • Other foods, including fatty fish like wild Alaskan salmon, contain omega-3 fatty acid. A study completed on medical students in 2011 was one of the first to show that omega-3s may help reduce anxiety. (This study used supplements containing omega-3 fatty acids). Prior to the study, omega-3 fatty acids had been linked to improving depression only.
  • A recent study in the journal Psychiatry Research suggested a link between probiotic foods and a lowering of social anxiety. Eating probiotic-rich foods such as pickles, sauerkraut, and kefir was linked with fewer symptoms.
  • Asparagus, known widely to be a healthy vegetable. Based on research, the Chinese government approved the use of an asparagus extract as a natural functional food and beverage ingredient due to its anti-anxiety properties.
  • Foods rich in B vitamins such as avocado and almonds

These “feel good” foods spur the release of neurotransmitters such as serotonin and dopamine. They are a safe and easy first step in managing anxiety.

Walnuts

Are antioxidants anti-anxiety?

Anxiety is thought to be correlated with a lowered total antioxidant state. It stands to reason, therefore, that enhancing your diet with foods rich in antioxidants may help ease the symptoms of anxiety disorders. A 2010 study reviewed the antioxidant content of 3,100 foods, spices, herbs, beverages, and supplements. Foods designated as high in antioxidants by the USDA include:

  • Beans: Dried small red, Pinto, black, red kidney
  • Fruits: Apples (Gala, Granny Smith, Red Delicious), prunes, sweet cherries, plums, black plums
  • Berries: Blackberries, strawberries, cranberries, raspberries, blueberries
  • Nuts: Walnuts, pecans
  • Vegetables: Artichokes, kale, spinach, beets, broccoli
  • Spices with both antioxidant and anti-anxiety properties include turmeric (containing the active ingredient curcumin) and ginger.

Achieving better mental health through diet

Be sure to talk to your doctor if your anxiety symptoms are severe or last more than two weeks. But even if your doctor recommends medication or therapy for anxiety, it is still worth asking whether you might also have some success by adjusting your diet. While nutritional psychiatry is not a substitute for other treatments, the relationship between food, mood, and anxiety is garnering more and more attention. There is a growing body of evidence, and more research is needed to fully understand the role of nutritional psychiatry, or as I prefer to call it, Psycho-Nutrition.

Best Supplement To Improve IQ By 10%

Docosahexaenoic acid (DHA) — an omega-3 fatty acid — can improve IQ by 10%, new research finds.

People in the study, who were aged over 65, were given 2g/day of DHA for a year.

A control group was given a placebo of corn oil.

The high quality study involved 240 Chinese individuals.

Their IQ and other measures of cognitive function were tested after 6 and 12 months.

The study’s authors explain the results:

“…oral DHA supplementation (2 g/d) for 12 months beneficially affected global cognitive function, specifically participants’ performance on the Information and Digit Span tasks.”

Brain scans also revealed changes in the hippocampus, an area of the brain critical for memory.

The study’s authors write:

“The hippocampus is a critical brain region for memory formation and plays important roles in the consolidation of information from short-term memory to long-term memory and spatial navigation.
[…]
Our results suggest that 12-month DHA supplementation significantly increased hippocampus volume.
Notably, we observed a 6.13% volume increase in the left hippocampus, a 1.89% increase in the right hippocampus, and a 0.29% increase in total hippocampus.”

omega3
Best supplement for older adults
with mild cognitive impairment (MCI).

Best supplement combination?

The use of omega-3 to prevent dementia has provided some mixed results.

B vitamins also seem to be important in warding off cognitive decline.

A recent study found that B vitamins combined with omega-3 can help slow mental decline in older people with memory problems.

The study’s first author, Dr Abderrahim Oulhaj explained the results:

‘We found that for people with low levels of Omega-3, the vitamin supplements had little to no effect.
But for those with high baseline Omega-3 levels, the B vitamins were very effective in preventing cognitive decline compared to the placebo.’

Other studies, though, have been less positive about the benefits of omega-3 for cognitive decline.

It is likely that the combination of nutrients — including both B vitamins and omega-3 will turn out to be the crucial factor.

The study was published in the Journal of Alzheimer’s Disease (Zhang et al., 2016).
