Diets Through History: The Good, Bad, and Scary

23 Studies on Low-Carb and Low-Fat Diets — Time to Retire The Fad
These diets attract people who want to lose weight quickly and easily and keep that weight off [10] or who want to be healthy and find that belonging to a group of people defined by a strict way of eating helps them to avoid the many bad food choices available in the developed world. The study researchers analyzed information from more than 2, men ages 42 to 60, who kept track of the food they ate for four days. Many experiments have confirmed the ability of people to mentally control pain. Everyone who has looked has noticed that in two different newspapers, their horoscopes read two different things. Agatston devised the South Beach diet during the s because he was disappointed with the low-fat, high-carb diet backed by the American Heart Association.

Non-Celiac Gluten Sensitivity does not seem to be a real entity according the current evidence, but this has not stopped the gluten-free fad, which may be causing real harm. There is a simple reason we strongly promote science-based medicine — it results in the best outcomes for individuals. That is true by definition, since the SBM approach is to use the best evidence and science available in order to determine which interventions result in the best outcomes.

There are numerous ways in which relying upon poor-quality evidence or invalid methods for making health decisions cause potential harm. Often the list is unimaginatively limited to direct physical harm, but that is only the tip of the iceberg.

There is financial harm, loss of opportunity to pursue more effective interventions, psychological harm from false hope and being deceived, and sacrifice of quality of life, time, and effort. Even without direct physical harm, with inert treatments like homeopathy, there is tremendous potential harm from relying upon fake medicine and bad science. But often there is potential physical harm, and even if slight it is not justified if there is no real benefit.

Medicine is a game of risk vs benefit — when the benefit is essentially zero, any risk is unacceptable. Even a small potential harm can be significantly magnified if it is marketed to the general public. The best overall advice we can give the public regarding healthy eating is to eat a variety of food with plenty of fruits and vegetables and watch overall caloric intake. Unless you have special medical considerations, simply eating a good variety of different kinds of food will take care of most nutritional concerns.

It will result in you getting enough of what you need and not too much of anything that can increase your risk. Having a restricted or narrow diet is always tricky, and runs the risk that you will be getting too little of some key nutrients and may be getting exposed to too much of others.

Therefore any diet which essentially consists of avoiding certain foods or heavily relying on others is likely to take you away from an optimal diet, and therefore be a net negative for your health. As I discuss in detail here , gluten is a composite of two proteins found in wheat, rye, barley, spelt, and related grains. For those with celiac disease, avoiding gluten is essential and even a small amount of gluten can cause serious symptoms.

There is a controversy, however, surrounding the alleged existence of so-called non-celiac gluten sensitivity NCGS. This is a hypothetical condition in which people may have a sensitivity to gluten without forming antibodies to gliadin or meeting the diagnostic criteria for celiac disease.

Discovering a new disease is always complex, and requires the identification of something definitive and discrete. We either need to identify a clear clinical syndrome, or some new specific pathology. For NCGS there is no clear pathology. If, however, we are going to base a new disease purely on clinical history, we need to make sure that the history is accurate and that we are not simply overinterpreting non-specific symptoms or falling victim to confirmation bias.

For example, there are people who feel they have a specific syndrome of sensitivity to electromagnetic waves, despite the absence of any identifiable pathology. However, properly blinded studies show that self-identified sufferers of EM sensitivity cannot tell when they are being exposed to EM waves in a blinded condition. For alleged NCGS the most salient evidence of its existence as a clinical entity are rechallenge studies.

In these studies subjects are challenged with either gluten or placebo, then the gluten is removed, and then they are later rechallenged. If NCGS is a real entity then their symptoms should resolve when gluten is removed and then return when rechallenged, at a higher frequency when the same is done with a placebo.

A recent systematic review of gluten rechallenge studies did not find significant evidence for NCGS. The prevalence of NCGS after gluten re-challenge is low, and the percentage of relapse after a gluten or a placebo challenge is similar. Something you must stick to as a creed.

Decades ago, this was the usual way of life of the communities around the Mediterranean Basin. It was the everyday life in countries like Spain, Italy or Greece. Its major points were physical activity, healthy nutrition and calm attitude.

And not much money to throw away. These elements shaped the Mediterranean culture. It is the only diet to have been awarded this recognition.

Nowadays, external influence has changed the original habits in those countries. Many qualified people are striving to get back what is the best nutrition pattern in the world. The Mediterranean Diet is the best way to live many years. And to live them well. It will keep you in shape, maintain your skin clean and beautiful and make your organs work properly. It is the right diet to keep you on shape, without risks. The Mediterranean Diet is the best way to prevent many diseases.

It also prevents metabolic syndrome, lung diseases, asthma, allergies, Parkinson, Alzheimer, and decalcification.
