The buzz word, for fighting hypertension and diabetes without medicines, is to follow ‘Paleolithic diet’. This prompted a search for the information available on this topic in the public domain for initiating a ‘healthy’ discussion!
Not only for BP and insulin dependent diabetes, but even for obesity and polycystic ovaries, same is the remedy. For those habituated to the modern food habits with carbohydrates, proteins, oils and fats, this prescription is a bit hard to ‘digest’.
Founding theory
A paleo diet is a dietary plan based on foods similar to what might have been eaten during the Paleolithic (Stone Age) era, which dates from approximately 2.5 million to 10,000 years ago. The aim of a paleo diet is to return to a way of eating that’s more like what early humans ate. The diet’s reasoning is that the human body is genetically mismatched to the modern diet that emerged with farming practices — an idea known as the discordance hypothesis (data on whether they were afflicted by BP and diabetes is anyway unknown!) Farming changed what people ate and established dairy, grains and legumes as additional staples in the human diet. This relatively late and rapid change in diet, according to the hypothesis, outpaced the body’s ability to adapt. This mismatch is believed to be a contributing factor to the prevalence of obesity, diabetes and heart disease today.
Researchers argue that the underlying hypothesis of the paleo diet may oversimplify the story of how humans adapted to changes in diet. The nutritional needs of the Paleolithic man may be different from the present age man, since he has to move always for food unlike the present day man and hence is not sedentary. Genetic research has shown that notable evolutionary changes continued after the Paleolithic era, including diet-related changes, such as an increase in the number of genes related to the breakdown of dietary starches.
Diet
In this dietary plan, it is recommended to take, Fruits, Vegetables, Nuts and seeds, Lean meats, especially grass-fed animals or wild game, Fish, especially those rich in omega-3 fatty acids, such as salmon, mackerel and albacore tuna, Oils from fruits and nuts, such as olive oil or walnut oil.
Those to be avoided are, Grains, such as wheat, oats and barley, Legumes, such as beans, lentils, peanuts and pea, Dairy products, Refined sugar, Salt, Potatoes and Highly processed foods in general.
Risk factors
A paleo diet may help you lose weight or maintain your weight. It may also have other beneficial health effects. However, there are no long-term clinical studies about the benefits and potential risks of the diet. Following risk factors need consideration:
1. Low to moderate carbohydrate intake: Paleo calls for the exclusion of cereal grains – wheat, rye, barley, oats, corn and brown rice, to name a few. These are great sources of fiber, B vitamins, iron, magnesium and selenium. Grains help our bodies control blood sugar, lower cholesterol and fight the risk of chronic diseases. Consistent low carbohydrate intake may lead to an overuse of fat for energy, also known as ketosis. Ketosis occurs when by-products of fat breakdown, called ketones, build up in the bloodstream. High levels of ketones can lead to dehydration and eventually coma due to severe metabolic abnormalities.
2. Restriction of dairy products: Dairy restriction can lead to deficiencies in calcium and vitamin D, which are critical to bone health.
3. Generous Intake of Saturated fats: Consuming the Paleo Diet-recommended amount of saturated fats can increase the risk of kidney and heart disease, as well as certain cancers. What about for those having tendency to form kidney and gall bladder stones?
4. High intake of red meat and high fat meat: Past and current research suggests that a heightened level of high fat meat and saturated fat can increase LDL (bad cholesterol) and the risk of bowel cancer. As per the American Heart Association, an adult should consume a total of ~13 grams of saturated fat per day. On a Paleo diet, saturated fat intake can approach upwards of 50 grams per day.
A word of caution
The long term effect on the health due to the absence of whole grains and legumes in the diet which are considered good sources of fiber, vitamins and other nutrients and also the absence of dairy products, which are good sources of protein and calcium are yet to be assessed.
In the end, eating like our ancestors isn’t required to live a healthy lifestyle; in fact, it could even cause adverse effects. While those living millions of years ago may have gotten by on this diet, evolution has altered our genetic makeup and how we digest food.
The other most important point is there is no evidence of their status of health. As the Paleolithic man could not have been a vegetarian, how to replicate the model for today’s pure vegetarians?
Also, would they have been healthier than you and me?
Conclusion
Before passing a judgement, let me add the favourable experiences of my close relative who is a staunch vegetarian. He had been long an insulin dependent diabetic medication with insulin dosages that slowly kept climbing up. He switched over to Palaeolithic dietary plan under a learned physician who is an experimentalist on this himself. He is perfectly healthy and would happily recommend to both ailing and otherwise friends.
But there shall be a clear understanding that there is no ‘one size fit all’. These regimens shall be strictly under the supervision of a dietitian with periodical monitoring of body parameters. In many cases only affluent can follow without risk. The bottom line is that it is a promising alternative to the present day indiscriminate medications with questionable quality of life.
With all the scientific knowledge and gadgets, the present day men are better equipped for any mid course corrections.
The old adage says, ‘Food is medicine‘ but unfortunately in todays’ life one takes medicine instead of food!
