Essential nutrients are those vitamins, minerals, fatty acids and amino acids that the body needs in order to function. We can't do without these substances and there are no other substances that can replace them. It is possible to live a full, long life without ingesting for example, ginseng, rose hips extract and medicine, but it is not possible to survive without getting all the essential nutrients. Deficiency of these substances will inevitably lead to nutritional deficiencies.
Essential in this context means vital or lifesaving.
Nutrient is any substance which when ingested contributes to the body's metabolism, function or growth.
Non-essential nutrients are all the nutrients that the body itself can form.
Essential nutrients - vital for our health
There are 45 nutrients plus water (= 46 substances) which are essential for the body. Essential nutrients are the substances that the body cannot produce and which are
indispensable to the body. This means that a deficiency of one or more of these substances will cause symptoms and ultimately lead to fatal disease. These nutrients are the foundation for our health, and you should always ensure that the supply is optimal. These nutrients have been essential to our health and survival throughout human history and that will not change. In 100 years from now, the same 45 nutrients will be every bit as necessary for our health and survival - regardless of our geographical location, color, age and gender.
