Coconut: Craze or Credible!

The Chicago Tribune has done some research on the Coconut Craze.

Liz Applegate, director of sports nutrition at the University of California-Davis, thinks coconut water is fine to drink for hydration ? if you like the taste.

Applegate takes issue with some of the health endorsements including weight loss and heart health claims.

It would be nice to see this kind of scrutiny given to all nutritional claims made by big business:

Most of these sites that promote and sell coconut oil originate from coconut-producing countries, including India, Indonesia and the Philippines.

Instead of research studies, you’ll find articles written by coconut oil advocates ? including Mary Enig, vice president of the Weston A. Price Foundation, a controversial organization that is critical of “traditional diets” and extols the benefits of saturated fat.

Trans fat needs a warning label

Trans fat roles in the body include:
? Lowers high density lipoproteins (HDL), otherwise known as the ?good
cholesterol?.2
? Raises low density lipoproteins (LDL), otherwise known as the ?bad cholesterol?.2
? Raises C-reactive protein, a substance in the blood that indicates arterial inflammation and is said to indicate proneness to heart disease.3
? Raises Lipoprotein (a) (Lp(a)), a substance in the blood that indicates arterial inflammation and is said to indicate proneness to heart disease.4
? Raises C-reactive protein, a substance in the blood that indicates arterial inflammation and is said to indicate proneness to heart disease.5
? Promotes improper management of blood sugar thus having detrimental effects in diabetics.6
? Interferes with the function of the immune system.7
? Decreases the bodies ability to utilize and decreases the amount of the healthy omega-3 fatty acids in our tissues.7

What are trans fats? They are poison in our food supply. ?The latest government study confirms that trans fat is directly related with heart disease and increases LDL cholesterol. Because of that, the Institute of Medicine, a branch of the National Academy of Sciences, declared there is no safe amount of trans fat in the diet.?8 ?There should be a warning on food made with this stuff like there is on nicotine products. It?s that bad for you, says Dr. Jeffery Aron, a University of California at San Francisco professor of medicine and one of the nation?s leading experts on fatty acids and their effect on the body.9

8 reasons to eat more saturated fat

Sources of saturated fat: Beef, beef tallow (fat), dairy, palm oil, coconut oil.

Saturated fats? roles in the body include: [1]

? They constitute at least 50% of our cell membranes and give our cells integrity.
? They play a vital role in the health of our bones.
? They lower Lp(a), a substance in the blood that is said to indicate proneness to heart disease.
? They protect the liver from alcohol and other toxins like Tylenol (Acetaminophen).
? They enhance the immune system.
? They are needed for proper utilization of essential fatty acids.
? Stearic acid and palmitic acid, both saturated fats, are the preferred energy source of the heart. This is why the fat around the heart muscle is mainly saturated. The best sources for palmitic acid are beef, butter and palm oil.
? Short and medium chain saturated fatty acids have strong antimicrobial properties. They help protect us from harmful microorganisms. The best sources are tropical oils such as coconut oil and palm oil.

Sturated fat doesn’t lead to heart disease

A recently published meta-analysis looked at 347,747 subjects in twenty-one studies to summarize the evidence related to the association of dietary saturated fat with risk of coronary heart disease (CHD), stroke, and cardiovascular disease. During the 5 – 23 year follow-up 11,006 of the almost 350,000 subjects developed CHD or stroke.

Conclusion: Saturated fat consumption was not associated with an increased risk of heart disease or stroke

Calorie restriction or carb depletion to increase lifespan

Since the discovery that calorie restriction increased lifespan, many studies have been performed including studies with non-human primates; all with overwhelming evidence. However, the mechanism by which lifespan increases through calorie restriction, has eluded researchers.

Data on the physiologic effects of caloric restriction in rhesus monkeys resembles rodent studies demonstrating reduced body and fat mass, lower blood glucose, insulin, leptin, free T3 (decreased body temperature), and serum triglycerides. Interestingly, centenarians have lower blood glucose, insulin, leptin, free T3 and serum triglycerides than those who do not live to be over one hundred years old. One can conclude, the fundamental mechanism by which calorie restriction improves lifespan appears to alter these metabolic factors.

A new study analyzed the data from patients attending a private practice. These patients were referred for the treatment of diabetes, cardiovascular disease, overweight, fatigue, and other chronic diseases of aging.

The diet:
? Calories were not explicitly restricted; patients were told to eat when they were hungry.
? Recommended sources of fat included; raw nuts, seeds, avocados, olives, olive oil, flax oil, and cod liver oil.
? Protein intake was limited to 1.0g/kg of lean body mass. If the subjects exercised it was increased to 1.25g/kg.
? Recommended sources of protein included sardines, fish, eggs, tofu, chicken, turkey, wild meats, low fat cheeses, seafood, and vege burgers.
? Carbohydrate sources included only non-starchy fibrous veges; lettuce, greens, broccoli, cauliflower, cucumbers, mushrooms, onions, peppers, etc.
The average daily macronutrient intake ended up being 20% carbs (most of which was fiber), 20% protein, and 60% fats.

The results: Serum insulin decreased by 48 percent, leptin decreased by 8 percent, fasting glucose by 40 percent, triglyceride by nearly 8 percent, and free T3 by almost 6 percent.

The key factor in this study is the participants were not limited in the amount of food they could consume. The researchers wanted to focus on the types of foods or macronutrients that would result in improved health and a longer life.
