Cognitive Enhancers:

Smart Nutrients for Boosting Brain Health

by:  Kimberly Pryor

 

The brain is mission control on our journey through life, sending sensory impulses through nerves that register as sensations. The brain is the driving force behind who we are, the center of consciousness, thought, memory, reason, judgment and emotion.

This large, soft nerve tissue mass cradled within the cranium is the primary center for regulating and coordinating body activities. Anyone who has lost his or her car keys or forgot to pay the power bill is reminded of the importance of this bundle of neurons sitting atop our heads. Loved ones of Alzheimer’s disease or dementia patients also are all too aware of the vulnerability of the aging brain.

Clearly, as we grow older, supporting optimal brain health is a priority. Consequently, implementing nutritional strategies to nourish our mental resources can prove helpful.

 

Acetyl-L-Carnitine

Acetyl-L-Carnitine (ALC) enhances production of the memory-enhancing neurotransmitter acetylcholine and participates in cellular energy production, a process especially important in neurons. Animal studies show that ALC reverses the age-related decline in the number of neuron membrane receptors.

Cognitive function is controlled by the central nervous system, which in turn is controlled by the cholinergic system, a collection of cells that either produce or are stimulated by the neurotransmitter acetylcholine. Two types of receptors respond to acetylcholine to trigger intracellular communication, memory processing and higher cognitive functions. The enzyme acetylcholinesterase rapidly breaks down acetylcholine, which is why a class of drugs known as acetylcholinesterase inhibitors are frequently used to treat cognitive decline. By blocking acetylcholinesterase, these inhibitors stop acetylcholine breakdown, an action thought to improve cognitive health.

ALC may work together with acetylcholinesterase inhibitors to increase their effectiveness in patients normally unresponsive to these drugs. Italian researchers performed an open study to evaluate ALC’s effect (2 grams per day orally for 3 months) combined with one of two acetylcholinesterase inhibitors in 23 patients with mild Alzheimer’s disease.1

When the acetylcholinesterase inhibitors were given alone, the patients experienced a 38 percent response rate to the drugs. The response rate rose to 50 percent when the patients were also treated with ALC. This led the researchers to conclude that the combination of ALC with the drugs may be “a useful therapeutic option in Alzheimer’s disease patients.�?/FONT>

In another evaluation of ALC’s effects, Stanford researchers reanalyzed data from a 1996 double-blind, placebo-controlled study that included 334 subjects diagnosed with probable Alzheimer’s disease.2 Both the ALC group and the placebo group exhibited the same mean rate of change on the Alzheimer Disease Assessment Scale. However, when the researchers analyzed the patients by age group, younger subjects experienced a significant benefit from ALC treatment. Patients 61 years of age and younger appeared to benefit most from ALC. The researchers concluded, “ALC slows the progression of Alzheimer's disease in younger subjects.�?/FONT>

In a meta-analysis investigating the double-blind, randomized, controlled clinical trials of acetyl-L-carnitine versus placebo researchers concluded that ALC can benefit Alzheimer’s patients.3 They looked at studies that used subjects with mild cognitive impairment and mild Alzheimer’s disease. All the studies included in the analysis lasted from 3 to 12 months and the daily dose varied between studies from 1.5 to 3 grams per day. The analysis showed that subjects treated with acetyl-l-carnitine experienced significant improvement on various measures of disease symptoms compared to subjects taking a placebo. ALC’s beneficial effects included improvement in intelligence, aptitude, behavior, and emotional reactions. The researchers noted ALC’s benefits at the first, three-month assessment and the benefits increased over time.

Vinpocetine

Vinpocetine increases the brain’s blood circulation. Animal studies have shown vinpocetine can reduce the loss of neurons due to decreased blood flow. In three studies of older humans with memory problems associated with poor brain circulation or dementia-related disease, vinpocetine produced significantly more improvement than a placebo in attention, concentration, and memory.4

In a 2003 review of double-blind, randomized vinpocetine studies, researchers assessed vinpocetine’s efficacy and safety in the treatment of patients with cognitive impairment due to vascular disease, Alzheimer’s disease, mixed (vascular and Alzheimer’s disease) and other dementias.5

The three studies included in the review—all performed before the 1990s—involved 583 people with dementia treated with vinpocetine or placebo. The results showed that vinpocetine treatment did exert some benefits at 30 mg per day and 60 mg per day compared with placebo. Because the number of patients treated for 6 months or more was small, and only one study extended treatment to one year, the reviewers stated that they would like to see longer term, larger studies to validate vinpocetine’s potential benefit.

Vinpocetine’s ability to protect neurons is well researched. In Hungary, vinpocetine has become a reference compound in the pharmacological research of cognitive deficits caused by low oxygen (hypoxia) and ischemia. Early experiments with vinpocetine indicated five main actions: (1) selective enhancement of brain circulation and oxygen use without significant alteration in systemic circulation, (2) increasing the brain’s tolerance toward hypoxia and ischemia, (3) anticonvulsant activity, (4) inhibitory effect on phosphodiesterase, an enzyme critical for the breakdown of cyclic adenosine monophosphate, a nucleotide important in a variety of metabolic responses to cell stimuli and (5) improvement of blood properties and inhibition of “sticky�?platelets. Later studies in various laboratories confirmed the above effects, suggested vinpocetine also works by influencing sodium and calcium-dependent communication between neurons and clearly demonstrated that vinpocetine offers significant and direct neuroprotection both under in vitro and in vivo conditions.6

 

Huperzine-A

Huperzine-A is a potent inhibitor of acetylcholinesterase, the enzyme that breaks down the memory-boosting neurotransmitter acetylcholine. Huperzine-A crosses the blood-brain barrier smoothly, and tends to gravitate toward acetylcholinesterase. It has been approved as the drug for Alzheimer’s disease treatment in China. Clinical trials of huperzine-A in elderly patients with age-associated memory loss are underway in the U.S.7

Extracted from club moss, huperzine-A (Huperzia serrata) has demonstrated both memory enhancement and neuroprotective effects in animal and clinical trials. Recently it has undergone double-blind, placebo-controlled clinical trials in patients with Alzheimer's disease, significantly improving cognitive function and the quality of life.8-9

In one study, 202 patients with the diagnosis of possible or probable Alzheimer’s disease were randomly divided into two groups. One group of 100 subjects received 400 micrograms huperzine-A per day for 12 weeks; another group of 102 subjects received a placebo. The results indicated that huperzine-A-treated patients experienced a significant improvement of cognition, behavior, mood and quality of life compared to subjects on the placebo. Mild adverse effects such as insomnia were reported in three percent of the patients.10

 

Pyroglutamic Acid

Pyroglutamic acid is an amino acid present in large amounts in the human brain,cerebrospinal fluid, and blood. Pyroglutamic acid is known to support cognitive function and improves memory and learning in rats.

In a randomized, double-blind trial, pyroglutamic acid was compared with a placebo for assessing its efficacy in treating memory deficits in 40 aged subjects.11 Twenty subjects were treated with pyroglutamic acid and 20 with placebo over 60 days. Memory functions were evaluated at baseline and after 60 days of treatment by evaluating performance on six memory tasks. Pyroglutamic acid subjects experienced significant improvement. According to the researchers, “The results suggest that pyroglutamic acid is effective in improving some verbal memory functions in subjects affected by age-related memory decline.�?/FONT>

 

Galantamine

One of the newest and most promising cognitive-enhancing substances is galantamine. Studies have indicated galantamine can offer cognitive support to Alzheimer’s disease and dementia patients.

In one study investigating galantamine’s effect on behavioral symptoms in Alzheimer’s disease, researchers analyzed data from 2,033 subjects with mild-to-moderate AD who had participated in one of three randomized, double-blind, placebo-controlled trials.12 In these trials, which lasted from 3, 5, and 6 months, 686 subjects had received treatment with placebo and 1,347 subjects received treatment with 16 mg, 24 mg, or 32 mg of galantamine per day.

After analyzing the data, researchers determined that, compared to placebo-treated subjects, galantamine-treated subjects experienced statistically significant improvements in such symptoms as hallucinations, anxiety, apathy and aberrant motor behaviors.

Galantamine also may alleviate some of the cognitive symptoms of schizophrenia, according to a small study, although larger trials are needed to confirm these results.13

 

Choline and Phosphatidylserine

Because the neurotransmitter acetylcholine plays an important role in brain health, supplementing with substances that boost acetylcholine levels may support healthy memory. CDP-choline and phosphatidylserine have both been shown to boost acetylcholine levels.

A review of cognitive enhancing substances in the November-December 2003 issue of the journal Nutrition, noted that, in animals, phosphatidylserine attenuated many neuronal effects of aging and restored normal memory on a variety of tasks.14
In older adults with probable Alzheimer’s disease, a single study failed to demonstrate positive effects of phosphatidylserine on memory performance. For older adults with moderate cognitive impairment, however, phosphatidylserine has produced consistently modest increases in recall of word lists. Phosphatidylserine also produced consistent benefits on a number of memory tests in a subset of normal adults who performed more poorly than their peers at baseline.

Most of the earlier research, conducted with bovine phosphatidylserine, showed phosphatidylserine could indeed alleviate some of the cognitive decline seen in dementia patients. A more recent, smaller study using soy-derived phosphatidylserine yielded similar results.15

Phosphatidylserine also has been shown to act as a powerful cortisol-lowering agent. High cortisol levels, often seen as we age and with exposure to chronic stress, have been implicated in cognitive decline, so phosphadtidylserine’s cortisol-lowering properties can play an important role in alleviating the negative effects stress can have on memory.16

 

Conclusion

A discussion of every cognitive enhancing nutrient is beyond the scope of this article. The nutrients profiled above are some of the most effective memory supporting natural substances available. Combining the nutrients mentioned above with other cognitive enhancers such as DMAE, phenylalanine, and ginkgo biloba may help the brain function at its maximum capacity.

Lignans linked to better cognitive function

 

30/05/2005 - Consumption of lignans could help preserve cognitive function in postmenopausal women and decrease their risk of developing Alzheimer’s disease, according to researchers at the Julius Center for Health Sciences and Primary Care in Utrecht, The Netherlands.

Several studies over the past five years have presented evidence that cognitive decline can be a precursor to Alzheimer's, in which diet is thought to be a contributing factor.

When women experience the menopause, their natural estrogen levels decline gradually over two to ten years. The presence of estrogen receptors in the central nervous system indicates its role in cognitive function, but the side effects of estrogen replacement therapy (ERT) may include increased risk of breast cancer and cardiovascular disease, and vaginal bleeding.

Given these drawbacks, interest has been piqued in the effects of phytoestrogens obtained from the diet, which may provide the same benefits as ERT, without the risks.

But according to the Dutch researchers, whose study is published in the Journal of Nutrition (135, 5:1190-1195, 2005), data on the relationship between phytoestrogens and cognitive function are still sparse.

They set out to examine how dietary intake of two phytoestrogens, lignans and isoflavones, in the typical Western diet may affect cognitive function in postmenopausal women.

The main dietary sources of lignans are oil-seeds, linseeds, broccoli and berries. Isoflavones occur in soy products, beans, peas, nuts, tea and coffee.

The study involved 394 healthy postmenopausal women who had an intact uterus, at least one intact ovary and had not used hormonal replacement therapy since their last menstrual period. Of these women, 196 experienced a natural menopause between 1969 and 1979 and 207 between 1987 and 1989.

Their intake of phytoestrogens during the year prior to enrollment in the study was estimated by a validated food frequency questionnaire. Cognitive function was assessed by a mini-mental state examination (MMSE), which involved questions and tasks associated with orientation, registration, attention, calculation, recall and language.

Since diagnosis of dementia was not the aim, the cut-off score for intact cognitive function was relatively high �?26 or more out of a possible 30. After adjustment for confounders, women who consumed higher levels of lignans performed better in the MMSE, and the results were more pronounced amongst the women who experienced menopause between 1969 and 1979.

Establishing a reason for this difference was outside the scope of this study but possible explanations were put forward by the researchers, such as some other age-related mechanism. The 1969 to 1979 group had a mean age of 69.2 years, compared with 63.5 years for the 1987 to 1989 group.

"An alternative explanation is that the protective effect of endogenous estrogens on the nervous system us dependent on cumulative time of exposure rather than on actual levels of intake," they wrote.

However the researchers could establish no relationship between isoflavone intake and cognitive function �?an apparent contradiction to the findings of a study published in Psycopharmacology in 2001, which concluded that isoflavones from soy may indeed positively effect cognition.

Other research underway in The Netherlands is investigating lignans' potential to alleviate the effects of age-related conditions in men.

Earlier this month Acatris http://www.acatris.com released the results of an animal study suggesting that flax lignans may help treat benign prostate hyperplasia, a condition said to affect more than half of all men over the age of 50. A human clinical study to test the theory further is expected to take place later this year, and will also look at the effect of lignans on hair loss.

 If You Want to Keep Your Brain Healthy You Need This Nutrient

Older people who eat food containing high amounts of folate, which is found in many leafy green vegetables and fruits, can cut their risk of developing Alzheimer's disease by more than half.

This may eventually lead to a means of keeping Alzheimer's at bay. Right now, there is no preventive therapy for the neurological disease.

Ten-Year Study

A 10-year study showed that people who consume at least 400 micrograms of folate a day (the recommended daily allowance of the vitamin) experienced a 55 pecent lower risk of developing the disease..

Folate reduces blood levels of homocysteine, a substance that can injure brain cells. Foods rich in folate include oranges, broccoli, spinach and bananas.

Alzheimer's Association  http://www.alz.org/news/05q3/081205.asp  August 12, 2005  

Dr. Mercola's Comment:

I first noted the importance of eating whole foods with high amounts of folate to prevent Alzheimer's disease five years ago. This new study is yet more evidence of this. Green leafy vegetables, strawberries, liver, kidney, nuts and other folate-rich foods can all help keep the nerve cells of your brain from being damaged.

The results of this study mirror the findings of one I posted last month about high amounts of folic acid slowing the cognitive decline that comes with aging .

Fresh vegetables, especially dark green, leafy ones, and strawberries are some of your best natural sources of folic acid. Eating plenty of fresh, uncooked vegetables is the natural way to ensure you are receiving an ideal daily dose of folic acid (and hundreds of other known and unknown nutrients).

However, it's also important to understand that we all require different amounts of vegetables to stay healthy. Some people need to consume as much as 300 percent more vegetables than others. The amount of vegetables your body requires depends on your body's specific metabolic type. While we all need vegetables to stay healthy, your metabolic type should determine the type and amount.

Can vitamins help prevent Alzheimer's disease?

Many HSI members are well aware that an elevated level of homocysteine (an amino acid) increases the risk of heart disease and other cardiovascular problems. And they also know that foods and supplements rich in vitamins B6, B12, and folate can help reduce homocysteine.

Less well known, however, is a demonstrated link between high homocysteine and an increased risk of Alzheimer's disease (AD) and dementia.

So we return to the original question: Can vitamins (specifically, the ones mentioned above) help prevent Alzheimer's disease?

--------------------------------------------
Predicting decline
--------------------------------------------

Last year, researchers from the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University recruited more than 320 healthy older men from a Veterans Affairs study on aging. At baseline, all of the men completed food-frequency questionnaires, and blood was drawn from each subject to measure B vitamins and homocysteine. Over the following three years the men took occasional tests to monitor cognitive function.

At the conclusion of the study, researchers reported these results:

      •  
        High homocysteine levels were associated with a decline in recall memory

      • High folate levels were significantly linked to verbal fluency

      • Subjects with elevated folate levels had fewer declines in spatial copying (a drawing test that measures the brain's ability to understand and reproduce geometric figures)


Writing in the American Journal of Clinical Nutrition, the USDA authors concluded that, "Low B vitamin and high homocysteine concentrations predict cognitive decline."

--------------------------------------------
Get the NAC
--------------------------------------------

Vitamins B6, B12, and folate have been proven to help metabolize homocysteine. These nutrients are abundant in asparagus, lentils, chickpeas, most varieties of beans, and especially spinach and other leafy green vegetables. But many people don't absorb B vitamins well, so in addition to these food sources a good B-complex supplement is often required to lower homocysteine levels.

According to several studies, supplements of the antioxidant amino acid N-acetylcysteine (NAC) may also lower homocysteine levels.

In 2001 I told you about a study that showed how NAC improved cognitive function in patients with probable Alzheimer's disease. The 24-week study of 47 subjects revealed that those participants who took NAC showed improvement in nearly every outcome measure, without experiencing any negative side effects.

--------------------------------------------
Adding two more
--------------------------------------------

Once homocysteine levels are addressed, there are other nutrients that may offer further protection from Alzheimer's. In the e-Alert "Form Rides with Function" (4/20/05), I told you about two studies from Johns Hopkins University that show how two key vitamins may support cognitive function.

In the first study, nearly 580 subjects, aged 60 or older, were followed for more than seven years. A diet high in vitamin E (spinach, eggs, nuts, seeds, avocados, tomatoes, peaches and blackberries) was strongly associated with a significant reduction of Alzheimer's risk. Intake of dietary vitamin C was found to be somewhat useful in reducing AD risk, but less effective than vitamin E.

Nearly two years later, another Johns Hopkins team interviewed more than 4,700 subjects aged 65 or older. Supplement intake was assessed, as well as the prevalence of dementia and Alzheimer's disease, from 1995 to 1997, and again from 1998 to 2000. Evaluation of the data showed that in the first phase, those who took supplements of vitamins C and E combined had a 78 percent lower risk of AD. In the second phase, the percentage dropped to 64, but still indicated a significant level of protection.

In addition, Alzheimer's risk was even lower among subjects who took a vitamin E supplement along with a multivitamin that contained vitamin C.

To Your Good Health,

Jenny Thompson

 Protecting The Brain From Decline and Dementia
Jerome Wener, M.D.

"Of all the things I have lost, its my mind that I miss the most." Can you relate to this expression? If so, you are not alone. America's increasing proportion of older people has resulted in a rising prevalence of dementia and Alzheimer's disease. In 1986, healthcare costs were estimated at more than $50 billion per year for dementia and associated diseases. If you are concerned about your risk of nerve degeneration, don't despair. There are plenty of ways to combat age-associated memory loss, without side effects. In fact, you can even improve cognitive function with the right supplements and a proper diet. In addition, if you have a family history of Alzheimer's, you can greatly decrease your risk of brain degeneration if you follow the simple guidelines listed below.

 

Phosphatidyl Serine
If you can pronounce it, you're already ahead of the game. Phosphatidyl Serine (PS) is a phospholipid that is present in every cell membrane in the body, though it is most prevalent in brain tissue. PS is present in trace amounts in foods, but to obtain optimal amounts through the diet, you would have to actually eat animal brains. Supplementation is therefore ideal for obtaining PS, since commercially available PS is synthetically derived, and free of all animal products.

What is the role of PS in the body? PS is like the superintendent of the brain; it is actively involved in the repair and maintenance of each cell's structure in the body and the nervous system. Its benefits include memory improvement, improved learning, alleviation of Alzhei mer's symptoms and early dementia, greater attention span, mood enhancement, fighting depression, and combating stress. PS readily crosses the blood-brain barrier and shuttles glucose to the nerve cells so they are well fed and energized. It works rapidly, too; studies have shown PS to be effective within 30 minutes of oral administration. I use PS for my patients with age-associated memory decline, Alzheimer's, brain injuries, attention deficit disorder, or for those who simply want to enhance their mental power. The therapeutic dose of PS is 300 to 500 milligrams per day, and the memory-enhancing effects of PS can last for up to a month after supplementation is discontinued. Note that PS should be avoided while using prescription anti-coagulants such as Coumadin or Heparin.


Acetyl-L-Carnitine

Acetyl-L-Carnitine (ALC) is another vital nutrient for brain health. A number of scientific studies have shown that carnitine, a nutrient consisting of the amino acids lysine and methionine, helps slow the progression of Alzheimer's disease. L-carnitine is used as a fat burner and a heart-supporting nutrient, while ALC enhances concentration. ALC has many of the benefits of PS, such as fighting depression and brain aging, improved learning, and stress management, but it also regulates sleep/wake cycles and improves long-term memory. And the benefits of taking ALC can be seen as early as three months. Those with Alzheimer's and dementia, peripheral neuropathies, memory loss, and major depression should use ALC, and it also has clinical uses in chronic fatigue syndrome and bodybuilding.

Around the age of 40, the body's production of ALC begins to decline, making it a required supplement for protection against age-associated memory loss and neurodegen erative conditions. The dosage ranges from 500 to 1,000 milligrams and should be gradually introduced over the course of a week. Recent studies performed at the University of California and confirmed world-wide demonstrate ALC is enhanced when combined with the alpha lipoic Acid. It has been documented as safe for long-term use, though anyone with a seizure disorder should avoid ALC, as it is questionable whether or not it will overly stimulate the nervous system. ALC can be extremely energizing, so be sure to take it before 4 p.m.


Gingko Biloba
The Gingko tree is the longest surviving tree species on the planet, dating back 200 million years. It has two fan-shaped leaves with a notch in the middle, dividing the leaves into two lobes; hence the name biloba. Gingko is extremely resilient and is found growing in many cities due to its ability to resist pollution, viruses, and insects. It is rich in flavonoids, which are antioxidant compounds found in plants that protect against cancer, heart disease, and premature aging. The Chinese used Gingko nuts for thousands of years as a remedy to promote longevity, improve impaired hearing, asthma, and to increase sexual endurance and improve circulation.

More than three hundred studies have demonstrated that gingko helps protect and promote memory and reliev e signs of senility, probably due to the increased blood flow to the brain. One study conducted at the New York Institute for Medical Research on patients suffering from dementia showed a significant improvement in 30 percent of those people taking gingko. This is very exciting news, since very few drugs have been shown to have any positive impact on dementia. Gingko can also help protect brain tissue against potentially dangerous chemicals called free radicals because it is rich in antioxidants.

The appropriate dosage for gingko can range depending on the indication. For general mental acuity, take 120 milligrams per day, and for Alzheimer's or vascular problems take 240 milligrams per day. No serious side effects have been reported with its use, and long-term use is believed to be safe. Choose a supplement that contains gingko-leaf extracts (24 percent flavone glycosides and six percent terpene lactones) to ensure a potent and effective product.

Gingko should be used with caution in patients taking anti-platelet drugs such as Warfarin (coumadin) or aspirin, antidepressants (tricyclics) and certain duretics, because the effect of platelet aggregation inhibitors may be increased. If you are taking any of these drugs, talk with your doctor before taking gingko.


Diet and Brain Power
Bear in mind that while all of the aforementioned supplements are remarkable, no supplement regime in the world can ever compensate for a poor diet. Excess sugar in the form of refined carbohydrates, poor-quality hydrogenated oils, and inadequate protein can also compromise mental acuity. Have you ever noticed how you feel in the mornings after eating a bagel versus an omelet? A typical New York bagel contains the carbohydrate equivalent of four pieces of bread, while an egg contains only one gram of carbohydrate per serving-a negligible amount-and is rich in protein and essential fatty acids. So if you feel like you're eating healthy, but can't seem to generate good mental power, then you may need to take a closer look at your diet.


Protein

Protein is the building block of our tissues. It is needed to make every living cell in our bodies and promote muscle growth. It balances hormones and blood sugar, fights sugar cravings, strengthens the immune system, heals wounds, and in some cases, keeps the gut healthy. But most important, it can have a positive effect on our mental function.

I can't tell you how many times I see patients come in to my office feeling tired, lethargic, having PMS, difficulty concentrating at work, and crave stimulants like sugar or coffee. Many of them are deficient in protein, and their symptoms magically disappear when protein is eaten at every meal.

What are the best proteins to eat? Whole eggs, lean chicken, fish, turkey, lean beef, and lamb are all good sources. Be sure to buy organic products as much as possible to reduce your exposure to antibiotics and pesticides. Eat two to four ounces of protein per meal and if you are physically activ e, you may need up to two times this amount. I guarantee that you will feel an improvement in mental function and greater energy levels when more protein is added to your diet.


Essential Fatty Acids
Fats can have a critical effect on our health and play an important role in the prevention of heart disease, cancer, and diabetes. Instead of concerning yourself with a low-fat diet, focus on eating the right fats that are rich in monounsaturated fatty acids and omega-3 fats. Both of these types of fats improve circulation and help keep cholesterol levels low and arteries clear. When your arteries are clear, oxygen can be delivered to your organs (especially the brain) more effectively. Unfortunately most of the foods we eat today contain partially hydrogenated vegetable oils and oxidized fats that are toxic to the body and clog up the arteries. Be sure to read the labels very carefully and avoid these fats at all costs; it can take up to two months to clear them from the body after they are eaten! A general rule of thumb is to simply avoid processed foods and you will avoid the toxic fats. Avocados, cold-pressed olive oil, olives, raw nuts and seeds, and fatty fishes contain beneficial fats that fight inflammation and will help fight the medical conditions that are prevalent in Westernized countries today. So think of fats as the grease on your squeaky wheel and give yourself an oil change!


Carbohydrates

Last but not least, I will address carbohydrates. Before I do, though, let me ask you to think about this: What did we do before the flour mill was invented? We ate whole foods and carbohydrates were eaten in the form of fruits and vegetables. Over time, we gradually began farming and agriculture developed, introducing whole grains into the diet: rice, quinoa, millet, amaranth, and potatoes. Then we evolved as a civilization and all of a sudden we were eating highly processed carbohydrates, like bread, potato chips, cereal, and pasta-not even distant cousins to the grains from which they grew.

While technology has changed, the body has not yet genetically evolved enough to be able to understand these foods and break them down properly. As a result, many of us feel tired or lethargic after eating too many carbohydrates. I am not saying you should never eat carbohydrates, but if you must, make them high in quality and low in sugar. Choose healthy choices such as fresh fruit, vegetables, beans, brown rice, plain oatmeal, sweet potatoes, and buckwheat. Keep the portion size of grains small and balance them out with plenty of healthy fats and high-quality protein and you will have the mental power of an army!


Conclusion

Using the supplements phosphatidyl serine, acetyl-l-carnitine, alpha lipoic acid, and gingko biloba in conjunction with a healthy diet can greatly improve mental and cognitive function. Taken together, these supplements promote optimal brain function and systemic circulation that can offset the symptoms of senility, Alzheimer's, and age-associated memory loss
