News Flash! Caveman Diet Good…Your Diet Bad

Swedish scientists have just published a research paper that indicates that eating a diet rich in lean meat, vegetables, berries and nuts is effective in lowering YOUR chances of suffering a heart attack or stroke.

Keeping in mind that it was only a three week study, and additional long term research will be required, scientists at the Karolinska Institute in Sweden found that the volunteers reduced body-fat, lowered their blood pressure and slashed levels of a blood-thickening agent (plasminogen activator inhibitor-1) known to cause deadly clots.

The results, published in the European Journal of Clinical Nutrition, support earlier scientific and real world findings that praise the health benefits of the Paleolithic/Caveman Diet.

The theory behind this way of eating is that prior to the advent of agriculture (10,000 years ago) our ancestors lived only on foods that could be speared or picked from trees and plants.

Some scientists argue the human genome has been unable to keep pace with our advances in agriculture and food preparation. The theory is that the modern human body is not genetically programmed to thrive on our modern diet. Our technology may be modern, but our bodies haven’t fully caught up and chronic ailments like obesity and type 2 diabetes are the result.

To that end, following the Paleolithic/Caveman Diet means no cereals, bread, milk, butter, cheese or sugar but plenty of lean meat, fish, fruits, vegetables and nuts.

To test its effect, the Swedish researchers recruited 20 healthy volunteers and put them on caveman rations for three weeks.

Each patient was assessed for weight, body mass index, blood pressure and cholesterol at the beginning of the experiment.

They were then given a list of stone-age foods they could eat, including fresh or frozen fruit, berries or vegetables, lean meat, unsalted fish, canned tomatoes, lemon or lime juice, spices and coffee or tea without milk or sugar.

Banned foods included beans, salt, peanuts, dairy products, pasta or rice, sausages, alcohol, sugar and fruit juice.

However, they were also allowed up to two potatoes a day and a weekly treat of dried fruit, cured meats and a portion of fatty meat.

After three weeks, the volunteers were tested again.

Among the 14 who successfully completed the diet, the average weight loss was around five pounds. BMI dropped by 0.8. Systolic blood pressure fell by an average of three mmHg. And the levels of plasminogen activator inhibitor-1 dropped by 72 per cent. Other favorable effects were the increase in antioxidants and a healthier potassium-sodium balance. One potential negative was the reduction of calcium. This effect should be addressed in further studies.

Official Scientific Conclusion:

This short-term intervention showed some favourable effects by the diet, but further studies, including control group, are needed. blah,blah,blah

My Conclusion:

Fruit, vegetables, lean meat good. Bagel-Fuls BAD

Breaking News! Heart Disease & Stroke linked to Diet

An article in today’s Telegraph, details startling new research that claims that “the leading cause of heart disease and stroke has been linked for the first time to a person’s diet and chemicals in the urine”.

Wow! A link between diet & health.

The study is apparently the first to link blood pressure to a person’s metabolic fingerprint.

Metabolic fingerprint is a catchy way of describing the the unique metabolites that are left behind by specific cellular processes. In this case, the scientists were looking at the metabolites (small molecules) found in urine, which reveal the way food is broken down in the body.

Getting to the point…

Western diets (rich in meat, high in alcohol and low in fibre) are bad.

People who eat a diet high in animal protein (indicated by the metabolite alanine being present in urine) have higher blood pressure, eat more calories, have higher cholesterol and body mass indexes.

People who eat diets higher in starches such as rice (indicated by the metabolite formate) have lower blood pressure and ingest fewer calories.

People who have healthy levels of gut flora (reduced by antibiotic use, increased by prebiotics and probiotics and indicated by the presence of hippurate in the urine) also have lower blood pressure. Hippurate is also present in the urine of individuals with low levels of alcohol intake and higher levels of dietary fibre.

While comparing the metabolic fingerprints of study participants in the U.K., United States, China and Japan, the scientists concluded that test subjects from the U.K. and the U.S.A. have similar genetic and metabolic profiles. In contrast, while the Chinese and Japanese participants had similar genetic profiles, they had different metabolic fingerprints.

What was most interesting was the comparison of the native Japanese participants with those Japanese individuals living in the U.S.A..

Japanese-Americans displayed a typical American metabolic fingerprint; indicating that lifestyle has a stronger effect on blood pressure & heart disease than genetics.

To summarize:

Eat more fruits & vegetables.

Thus endeth the lesson.
