There are many debates about the human diet. However, it can be said with certainty: Man can be mostly omnivorous: he can eat anything. He can vary his diet according to the seasons, the availability of foodstuffs and his tastes.
Vegetarians do not eat meat or fish. Vegetarians should not be confused with vegans. Vegans do not eat anything of animal origin (milk, eggs, butter, honey, wool sweaters, leather shoes…). For a long time, the vegetarian diet was decried as being bad for your health. This is not true at all. A vegetarian who eats a balanced diet and is careful to consume products that meet the needs of his or her body will be healthier than an omnivore who does not watch what he or she eats. Some studies have even shown that people who eat a vegetarian diet are healthier than others. A meatless diet reduces the risk of obesity, cardiovascular disease, cancer and type 2 diabetes.
The only potential deficiency that can persist in a vegetarian diet is iron. However, many omnivores experience iron deficiency, which is not unique to vegetarians. It is necessary to monitor this factor from time to time and to enrich one’s diet with iron-rich legumes such as pine nuts, spinach or sesame.
