What no one tells you about dietary fat

butterFor years the official advice has been to eat a low fat diet to avoid atherosclerosis. It is a widespread understanding that polyunsaturated fat are heart-healthy and saturated fats cause problem. And cholesterol has been described as the main villain to avoid at all cost.

But more recent research effort has turned this conception on its head and indicates that the previously held views are either incomplete or wrong.

The most decried myth nowadays is probably that of cholesterol. It is now understood that cholesterol is much more than a molecule to be simply avoided. For a start, cholesterol is the precursor of several hormones, including sex hormones (testosterone, oestrogen, progesterone). It is also used by the body to make bile, and is an integral component of cellular membrane; it is also an anti-oxidant[1] and a repair substance. It is necessary for correct brain function[2][3]. Finally, cholesterol levels are regulated by the body itself as the body produces most of the cholesterol it needs, whether you eat fatty foods or not.

Cholesterol initially got bad press as, in some cases, the lipoprotein molecule which carries cholesterol in the blood gets into an unhealthy state known as oxidised LDL[4], which is now very clearly associated with heart disease[5][6]. It is increasingly perceived that this unhealthy change is triggered by oxidative damage[7] and excessive consumption of polyunsaturated fats, oxidized seed oils and carbohydrates[8].

And why would our body hate us anyway and produce toxic substances? If the body makes cholesterol, it probably is because it needs to. Eat an anti-oxident rich diet and cholesterol shouldn’t be a worry.

If bacteria would not touch a food, should we really?

Modern diet and hormonal dysfunction

fat tummyToday’s official nutritional advice is all about low-fat high carbohydrate diet. When I first looked into nutrition from the perspective of our wild ancestors, it struck me how rare starches and carbohydrates were in a wild ecosystem.

Humans would have got relatively few high glycaemic index food (some fruits, honey). Tubers required digging up the ground and pulses generally required some processing (fermenting or cooking) to become edible.

Fruits, back then, where the wild equivalent of the ones we know today. High in phyto nutrients, low in sugar, only available when in seasons and rather unpalatable in most cases (have you tried a crab apple or a wild banana?). Getting a high starch diet from a naturally occuring forest is near impossible.

By further investigating nutrition, one gets to understand that all carbohydrates (whether complex or not) are sugars. When digested, those complex sugars are broken down into glucose, the blood level of which is tightly regulated by the body. Insulin is secreted to keep blood glucose constant and to store any excess into body fat.
When your diet comprises too much carbohydrate, several things can happen, including: (more…)

Human re-evolution

Human re-evolution

Human nutrition has changed tremendously over the last 100 years, to the point that many of us do not know any more what a natural way of eating is. Even worse, the food industry has developed technologies to fool our taste buds to such an extent that we lost our instinct of whether a food is good for us or not. Modern junk food is loaded with salt, sugar, MSG sweeteners and other chemicals in an attempt to disguise their lack of nutritional value.

Additives and artificial chemicals have been engineered to extend shelf life with little regards to their impact on human health. But in reality, if bugs and mould would not touch a food, should we really?

The rise of farming has been serious bad news for our environment. It led to mass clearing or burning of forests, overgrazing, massive soil erosion and the introduction of invasive species (goats, sheep and rabbits for instance). Agriculture remains to this day the number one and on-going cause of species extinction.

What is the best diet ???

Once upon a time, there were people who were virtually free from heart disease, cancer, diabetes, allergies, dental decay, poor eyesight obesity, depression and other mental illnesses. They didn’t have to exercise to stay fit. They were all slimmer, stronger, taller and faster than us. They were less sensitive to extremes of heat or cold, and ran in the great outdoors all day long with only few simple clothes if any. Their vigour allowed them to conceive and give birth easily and near pain-free until what we would consider an advanced age. Concepts of money, private property, laws, classes and casts were almost unknown to them, but they respected their elders. Although life was tough, they worked a lot less than we do now, had more free time, didn’t have a boss to report to, nor had to commute to a 9-5 work. They lived in near harmony with nature. They were us, before we invented agriculture. They were the world’s hunter gatherers. They were our ancestors. They gave us our genes.

Their secret? (more…)

Humanity’s worst mistake

Virtually all people on earth today are sustained by agriculture, while no other species is a farmer. Essentially all of the arable land in the world is under cultivation. Yet agriculture began just a few thousand years ago, long after the appearance of anatomically modern humans and long after the last significant genetic mutation in our specie.

Given the rate and the scope of this revolution in human society, it is quite extraordinary that there is no generally accepted model accounting for the origin of agriculture. Indeed, an increasing array of arguments over recent years have suggested that agriculture, far from being a natural and upward step, in fact led commonly to a lower quality of life. Hunter-gatherers of the past typically did less work for the same amount of food, were healthier, taller and stronger, had better endurance and bigger brains, healed faster and were less prone to famine than primitive farmers.[1]


In today’s world, with obesity and degenerative diseases sky-rocketing, nutrition is a topic that triggers passions in many, but only meets disinterest in others, based on too many incoherent advice and baseless affirmations.

Similarly, everybody is concerned about the destruction of the environment, but truly relevant solutions aren’t forthcoming as we seem unable to sacrifice our lifestyle.

The aim of this website is to explore why and how optimal nutrition and ecosystem health are one of the same thing and what does it imply for a practical sustainable living.
