If you’re keen to eat a healthier diet that’s more in tune with nature, you’re almost certainly aware of the trend towards raw foodism. Here we look at its benefits, risks and the best way to approach it.
Within the broad raw food movement, also referred to as ‘living’ food, there are many trends and types of consumer: (1)
What all these diets have in common is that the food is always, or primarily, eaten raw.
In fact, devotees of raw-foodism actually admit their consumption of raw food is closer to 75%-80%.
Eating a raw food diet normally results in significant weight loss which, for overweight individuals, may be the desired effect (2). This weight loss is the result, in particular, of giving up shop-bought biscuits and other processed foods.
However, this is not what most raw foodists believe to be the main advantage of their chosen diet.
Those responsible for popularising raw foodism claim that ‘eating raw’ enables all the vitamins in a food to be preserved (which is perfectly true), and in particular, all its enzymes too (equally true) (3).
These enzymes are believed to trigger the digestion of certain nutrients (carbohydrates and protein) in the stomach and thus facilitate the digestive process, leading to better absorption by the body.
In addition, as most raw foodists exclude animal-source products and rely mainly on alkalising foods, ‘eating raw’ is likely to promote good acid-base balance in the body.
A raw food diet may therefore lead to renewed energy and less digestive discomfort, and is, above all, a diet that’s closer to that of our ancestors. In this respect, raw foodism directly competes with the paleo diet.
We should remember, however, that the move to cooking food was one of mankind’s most important advances, as was confirmed by researchers at Harvard Graduate School of Arts and Sciences in a study published in the Proceedings of the National Academy of Sciences (PNAS) (4).
In fact, paleoanthropologists and archaeologists believe that humans have been cooking food for at least a million years and probably longer. It’s now widely accepted that the move to cooking meat was one of the main factors responsible for man evolving into homo sapiens (5).
Indeed, in addition to the fact that cooked meat provides more energy than raw meat (6), that the nutrients it contains are easier to absorb, and that less energy is needed for its digestion (7-8), the decrease in the amount of chewing required for cooked meat led to a reduction in jaw volume and an increase in that of the cranium.
What’s more, archaeologists have been able to prove that humans have also been cooking vegetables for at least 170,000 years, no doubt for the same reasons.
It also seems that cooking softens fibre structures making them less irritating to the colon, and destroys pathogenic microorganisms, thus reducing the risk of food poisoning.
As the raw food movement has been around for some time, data is available from several studies conducted on its followers. We’ve therefore learned that:
That being said, all these deficiencies can be corrected by adapting the diet and taking dietary supplements such as Methylcobalamine (for vitamin B12) or Vitamin D3 5000 IU, for example.
It’s also worth remembering that a multivitamin (such as Daily 3) contains a good level of these minerals and vitamins as well as other health-beneficial compounds.
Raw foodism offers undeniable benefits: raw, lacto-fermented or sprouted foods contain many vitamins, minerals and enzymes which, to a degree, promote digestion .
‘Eating raw’ also encourages a feeling of satiety, eliminates cooked fats from the diet, and necessarily involves eating nutrient-rich foods that are excellent for health (fruit, vegetables, seeds, oilseeds, sprouted seeds, etc.).
However, given the risks of a totally raw food diet, most nutritionists and doctors recommend eating a balanced diet comprising 50% raw foods (particularly those mentioned above) and 50% cooked foods (broccoli, potatoes/sweet potatoes, cereal grains, pseudo-cereals, meat, eggs, etc.).
As is so often the case, taking things to extremes with raw foodism poses a risk, while exercising moderation means you reap the benefits of each approach.

I am very happy with the products, they are clean and strong. You get real improvment in health. But your resent change with the desing of packets is stylish but not attractive. Also I wish back the fast delivery.
