The Whole Truth about Good Health & Eating Nuts . . .

nutrition | Posted by admin July 31st, 2010

Long ago our ancestors gathered nuts as a means for survival. Although no longer needed to persevere, nuts are still a staple in our diets today. Found on coffee tables, at baseball games, tossed in salads, stir fried with vegetables and topped on sundaes, nuts play an integral role in our culture. And they should. There is emerging evidence linking the consumption of nuts to a reduced risk of coronary heart disease.

Two large epidemiological studies, the Nurses’ Health Study (1) and the Adventist Health Study (2) assessed the diets of over 110,000 men and women in relation to coronary heart disease. Adjusting for other coronary heart disease risk factors, they linked the intake of five or more servings (five ounces) of nuts per week to a 35 – 50 percent reduction in risk of coronary heart disease incidence and death (1,2). This is great news, as over the years nuts have received more negative reviews on health than positive ones. Now you and your family can enjoy the culinary versatility, flavor, aroma and crunch nuts provide while at the same time reaping their heart-protective benefits.

Nuts come from many different plant families and are classified as either tree nuts (a one-seeded fruit in a hard shell) or peanuts (a member of the legume family).

A one-ounce serving of nuts contains between 160 and 200 calories, of which 80-90 percent comprises fat. Despite this high-fat content, the fat in nuts is primarily in the monounsaturated form. Monounsaturated fats, when substituted for saturated fat in the diet, can help reduce total and LDL, or “bad” cholesterol levels while maintaining the “good” cholesterol, HDL.

Other added benefits of nuts are they are naturally cholesterol free, a good source of dietary fiber and protein, and contain a variety of heart disease-fighting vitamins and minerals like vitamin E (a potent antioxidant), folic acid, niacin, magnesium, vitamin B 6, zinc, copper and potassium. Nuts also contain the nonessential amino acid arginine. Arginine is touted for it’s role in protecting the inner lining of the arterial walls, making them more pliable and less susceptible to atherogenesis. Lastly, nuts are a good source of healthful phytochemicals, biologically active plant chemicals with high antioxidant properties linked to prevention of coronary heart disease.

Because nuts are so calorically dense it is important to incorporate them into the diet sensibly. To avoid weight gain, substitute added nuts for food sources high in fat, specifically saturated fat. For example, top a salad with nuts instead of bacon bits and croutons. Proper serving size is also a must. Having a scale on-hand is your best bet, although not always practical. If a scale is not available, check the Nutrition Facts panel on the food label to locate the serving size. A one-ounce serving of nuts greatly differs.

The following equal one ounce: 24 almonds, 18 medium cashews, 12 hazelnuts or filberts, 8 medium Brazil nuts, 12 macadamia nuts, 35 peanuts, 15 pecan halves and 14 English walnut halves (3). Prepackaging nuts into small, single-serving containers or bags can help keep the servings under control. All it takes is one, one-ounce serving a day or five ounces per week of a variety of nuts to reap the heart-disease fighting benefits found in the research presented above.

However you enjoy them, remember that adding nuts to your diet is one of many nutritional strategies aimed at reducing your risk of coronary heart disease. The best way to reduce your risk is to combine a high-fiber diet, rich in complex carbohydrates (whole grains, legumes, nuts and seeds) to a variety of fruits, vegetables and low-fat dairy each day to reap optimal heart-health benefits. Add to the equation a healthy body weight and regular physical activity and you can effectively reduce your risk of coronary heart disease.

Some more nut facts:

  • Walnuts contain a large percentage of polyunsaturated fat and are an excellent source of omega-3 fatty acids. Omega-3 fatty acids effectively help reduce triglycerides and are linked to a reduced risk of heart disease.
  • Almonds contain calcium, around 80 milligrams in one ounce, and can be a healthful way to boost calcium in the diet.
  • Pine nuts are a good source of iron, containing almost 3 milligrams in a one-ounce serving.
  • The bulk of calories in chestnuts come from carbohydrate instead of fat. Five ounces of water chestnuts contain only 3 grams of total fat, but pack a whopping 350 calories.
  • Peanut butter contains the same heart-protective benefits as whole peanuts however, manufacturers add salt, sugar and sometimes partially hydrogenated fats to enhance flavor and spreadability. Opt for natural peanut butter, which contain fewer to none of these additives.**
  • Unsalted, dry roasted or unprocessed nuts are typically found in the baking isle, produce or bulk food section of the grocery store; salted, oil-roasted nuts in the snack section. To reduce sodium and added fats in the diet, avoid the salted, oil-roasted nuts.

** Note: a strong association between a reduced incidence of coronary heart disease and consumption of peanut butter was not found in the articles referenced. However, peanut butter can be incorporated into a healthful eating pattern and still provides a variety of heart-disease fighting nutrients. Consume in moderation.

Vitamin D – Its Role in Health & Optimal Athletic Performance

Fitness, Recovery - Repair, nutrition, performance | Posted by admin May 24th, 2010

There are a pandemic number of people who are vitamin D deficient.  This has become evident due to increased discovery and sharing of documentation from clinical trials, epidemiological studies, and educational journals.  The end results from an alarming and growing number due to lack of sunshine exposure and inadequate supply of vitamin D from daily food intake.   This added to obesity trends, an aging population, and improved skin products that block formation of vitamin D3.  Until recently, vitamin D was understood to be solely related to bone mineralization and calcium utilization in the body.   Further studies have revealed vitamin D to play a leading role in many additional cell processes.  More than 36 cell types and 10 extra renal organs have been discovered to possess the vitamin D receptor, or VDR. Insufficient vitamin D is related to reduced immunological conditions, cancers of the breast, colon, pancreas, and prostate as well as heart diseases, type I diabetes, rheumatoid arthritis, cognitive impairment, and all cause mortality.  This impressive collection of medical conditions accounts for more than 60% of all deaths in the Western World.

What is Vitamin D?

A fat soluble pro-hormone, vitamin D is a seco-steroid which exists in two forms:  vitamin D2 & vitamin D3.  Vitamin D2 is obtained from yeast and plant material, vitamin D3 is produced endogenously in the skin by the photo-chemical conversion of 7-dehydrocholesterol. Vitamin D circulates in the body bound to the vitamin D binding protein, or VDBP.  Both vitamin D2 and D3 are converted to the biomarker 25-hydoxyvitamin [D (25(OH)D] in the liver and undergoes further hydroxylation in the kidneys to the bio-active form of the hormone 1,25(OH)2D.

The Frequency of vitamin D Deficiency:

The March 2010 issue of the Journal of Clinical Endocrinology & Metabolism points towards an overwhelming 59% of people that are vitamin D insufficient.  This was based on a cross-sectional study designed to establish a relationship between serum 25(OH)D and the degree of fat penetration in muscle.  These results have been duplicated as well in several independent studies of people from all over the United States in recent months.

Adverse Outcomes of Vitamin D Insufficiency:

Presence of 1,25(OH)2D and vitamin D receptors (VDR) in a wide variety of tissues ranging from pancreas, colon, brain, liver, muscle, skin and lung  speaks of its newly found broad involvement in the functionality of bodily systems.  Published literature over several years indicates that the non-bone mineralization effects of vitamin D are autocrine, not endocrine.  Thus, implying these functions are not based or derived for the amount of circulating 1,25(OH)2D in the body, but rather due to the intracellular synthesis of 1,25(OH)2D by these tissues.  Studies also indicate that the levels of 1,25(OH)2D required for these non-calcemic functions are higher than the levels of normal serum 1,25(OH)2D. 

Epidemiological evidences have linked deprived levels of vitamin D conditions to osteoporosis, osteoarthritis, obesity, multiple sclerosis, hypertension, type I diabetes and several cancers.  Vitamin is also effective in maintaining low susceptibility to infections including pulmonary diseases.

Conclusion:

Vitamin D has been shown to have an extensive area of biological influence due to the discovery of VDR and its conversion in several body tissues.  Health, strength and athletic performance can be optimized by measuring the residual levels of vitamin D at the cellular level to determine the degree of insufficiencies in order to adjust diets and nutritional supplements which directly influences athletic strength and recovery time.

Glutathione Considered – The Body’s Master Antioxidant

Recovery - Repair, performance | Posted by admin November 22nd, 2009

Antioxidants are intimately involved in the detoxification process and are a very important part of our defenses against environmental toxins and carcinogens. They protect our cells from oxidative stress which can come from our environment in a variety of ways. Because such damage plays a role in the weakening of the immune system that it should come as no surprise that antioxidant supplementation can benefit those with degenerative diseases such cardiovascular disease, cancer, arthritis, neurological diseases and viral infections for example.

Let’s look at one antioxidant –Glutathione- and how glutathione can affect the body. Glutathione is a small molecule made up of three amino acids, which exists in almost every cell of the body. The presence of glutathione is required to maintain the normal function of the immune system. It is known to play a critical role in the multiplication of lymphocytes (the cells that mediate specific immunity), which occurs in the development of an effective immune response. The cells of the immune system produce many oxygen radicals as a result of their normal functioning, resulting in a need for higher concentrations of antioxidants than most cells. Glutathione plays a crucial role in fulfilling this requirement.

Glutathione helps the body fight almost any disease, because it is a powerful antioxidant and helps maintain cellular health and there is a body of research on degenerative disease that has shown that people with degenerative disease are also experiencing low levels of glutathione. Glutathione acts as a detoxifying agent by combining with undesirable substances and ridding the body of them through urine and bile. Aside from being a powerful antioxidant and system detoxifier, it helps repair and protect DNA. Glutathione has been heavily researched and many researchers believe that the degenerative processes take place when the body is lacking the glutathione it needs to protect from degenerative damage.

Glutathione works in a protective role by boosting the immune system, thereby helping the body’s immune response and helps protect the body from oxidative stress – and oxidative stress is associated with aging. Thus, glutathione levels are correlated with aging and physical function. One way to drastically increase glutathione levels, aside from consuming glutathione precursors, is through the ingestion of ascorbic acid – vitamin C3 – and l-glutamine, vitamin E, ALA (Alpha Lipolic Acid), and N-acetylcysteine (NAC) which all help with glutathione synthesis.

Oxidation damage is now recognized as being the key feature of much of the aging processes that our bodies endure. It is known that as we age, there is a precipitous drop in GSH levels. Lower Glutathione levels are implicated in many diseases associated with aging, including Cataracts, Alzheimer’s disease, Parkinson’s, arteriosclerosis and others.

The key to living better is to resist age related deterioration due to oxidation. Recent studies have shown that glutathione play a key role in reducing the oxidation process (antioxidant) and protecting our bodies against free radicals. Supplements that increase glutathione may be a way for us to protect our bodies against the aging process.

What can reducing the oxidative process on the body mean for the athlete?

Many world-class athletes are discovering the importance of glutathione, which when maintained, gives them the edge over the competition. Increased glutathione levels provides athletes with increased strength and endurance, decreased recovery time from injury, less pain and fatigue and possibly an increase in muscle-promoting activities.

During workouts, athletes generate free radicals which in turn lead to muscle fatigue and poorer performance. Glutathione neutralizes these radicals and allows our bodies to recover faster. Recent research indicates that the body has a natural tendency toward many degenerative diseases and aging itself. Some believe how well the body can protect itself from damage and recover from oxidative damage can be determined by measuring the intracellular stores of Glutathione.

Importance of Magnesium – Especially for Athletes

performance | Posted by admin June 19th, 2009

Most people are aware of the importance of getting enough calcium, which remains a widespread problem. Most people don’t know there are other common micronutrient deficiencies that need to be addressed. Magnesium is one of those important micronutrients that doesn’t seem to get much attention, but plays a huge role in the body promoting health & performance.

Unfortunately the diets of all Americans are likely to be deficient and they don’t even know it. Sources estimate that nearly 70 percent of Americans get inadequate doses of magnesium every day and do not consume the daily recommended amounts of Magnesium. Studies have also shown food alone can’t meet the minimal Recommended Daily Allowances (RDA) micronutrient requirements for preventing nutrient-deficiency diseases. For several years experts have suggested that the availability of magnesium in the soil has significantly decreased and it is difficult to get the amount of magnesium needed to function at an optimal level. This, in combination with diets low in whole grains and fresh fruits and vegetables, has led to a general deficiency in the population.

Magnesium is used for more than 300 bodily functions and assists in energy production, maintains healthy bone density and aids the electrical conduction of the heart. Magnesium belongs in a category of minerals called electrolytes because they conduct electrical signals in the body. It is needed in energy metabolism, glucose utilization, protein synthesis, fatty acid synthesis and breakdown, muscle contraction, all ATPase functions, for almost all hormonal reactions, and in the maintenance of cellular ionic balance. It is found in all of the body’s cells, although it is mostly concentrated in the bones, muscles, and soft tissues. Magnesium also affects calcium’s role in homeostasis through two mechanisms.

Magnesium deficiency results in altered cardiovascular function, including electrocardiographic abnormalities, impaired carbohydrate metabolism, with insulin resistance and decreased insulin secretion, and high blood pressure. Even a mild deficiency causes sensitiveness to noise, nervousness, irritability, mental depression, confusion, twitching, trembling, apprehension, insomnia, muscle weakness and cramps in the toes, feet, legs, or fingers.

In active adults and athletes low magnesium levels can acutely contribute to early fatigue, nausea, muscle cramps & an irregular heartbeat during exercise. Magnesium as well as zinc, chromium and selenium are excreted in the sweat or as part of the process of metabolic acceleration. Heavy sweat loss can interfere with the important functions for which magnesium and other electrolytes are responsible. Also, the rate of magnesium loss is increased in conditions of high humidity and high temperature. An important consideration for athletes is the rate of magnesium loss that occurs during heavy physical activity. Heavy exercise makes you lose magnesium in the urine and scientific evidence suggests this is why long distance runners may suddenly drop dead with heart arrhythmias.

In a very tightly controlled three-month US study carried out last year, the effects of magnesium depletion on exercise performance in 10 women were observed. In the first month, the women received a magnesium-deficient diet (112mgs per day), which was supplemented with 200mgs per day of magnesium to bring the total magnesium content up to the RDA of 310mgs per day. In the second month, the supplement was withdrawn to make the diet magnesium-deficient, but in the third month it was reintroduced to replenish magnesium levels.

At the end of each month, the women were asked to cycle at increasing intensities until they reached 80% of their maximum heart rate, at which time a large number of measurements were taken, including blood tests, ECG and respiratory gas analysis.

The researchers found that, for a given workload, peak oxygen uptake, total and cumulative net oxygen utilization and heart rate all increased significantly during the period of magnesium restriction, with the amount of the increase directly related to the extent of magnesium depletion. In plain English, a magnesium deficiency reduced metabolic efficiency, increasing the oxygen consumption and heart rate required to perform work – exactly what an athlete doesn’t want!

No serious athlete or trainer can afford to overlook the benefits that magnesium brings to athletic performance and the recovery process. Research suggests that even a small shortfall in magnesium can lead to greatly reduced performance and stamina. Many athletic medical specialists believe that magnesium is the single most important mineral to sports nutrition. Not only does it help optimize an athlete’s performance, but it speeds up recovery from fatigue and injuries.

Optimal muscle contraction and relaxation is the foundation of an athlete’s performance. Proper magnesium levels are required for muscles to relax fully following a contraction. Some doctors believe that injuries to hamstring muscles can be partially avoided through intake of magnesium and stated that a shortened hamstring is a result of lack of available magnesium.

The first step is to eat more magnesium rich foods, especially beans, nuts and vegetables. The more active a person is the greater the need to make sure there is a variety of balanced micronutrient-enriched foods into their diet. The challenge is to eat large amounts of magnesium-rich foods on a consistent basis. Often this proves difficult and unrealistic, as an athlete’s requirement of magnesium intake far surpasses that of an average person. Micronutrient supplementation still may be needed to be incorporated into their wellness program as a preventative protocol for preventing these observed deficiencies.

Another important step is to have your levels checked. The residual level of magnesium in the cells is what’s important. The body does all it can to keep the blood levels normal, so if there is a body deficit, it will be found within the cells. Work with a practitioner that will check your RBC-magnesium level (the level of magnesium in red blood cells) or provide an FIA (functional intracellular analysis) for your body’s residual nutrient levels that will benchmark your cell level status to find the amount of supplements needed to achieve normal levels. Recommended intake for endurance athletes is 500 to 800 mg daily.

There is virtually no one that cannot benefit greatly from increasing daily magnesium intake. In terms of health and longevity magnesium is essential. For the professional athlete it means the difference between winning and losing, and in some cases, living and dying.
