Key Takeaways
Every year, new dietary trends emerge that involve the exclusion of specific nutrients, adjustments to daily meal plans, or the necessity of supplements. The separate diet, also referred to as the diet of non-combination or Haya diet, has been around for decades and garners both support and criticism. Is it genuinely beneficial for health, and does its implementation yield the desired outcomes?

Separate diet
According to the author, Dr. Haya, the time of digestion of protein and carbohydrate products (including starches) is different, so they should not be consumed simultaneously during a single meal.[1] In the book Ursula Summ, we read that improper nutrition can inhibit metabolism, disrupt the work of internal organs and thicken the blood.
Diets separate from the rules
The principle of separation is to divide the products into 3 groups [2]: protein: freshly cooked meats: beef, eg. roasted apples, sausages, steak, salted meat, sausage; calves, eg., sausages and sausages; whole grains of whole grain products: whole-grain cooked vegetables, fresh grains, soybeans, tomatoes and other edible vegetables such as soybean crops, cereals, raisins, celery fruits, cereal grains and cereals (e.g. cereals; oats; oatmeal; pork; porridge; eg: oats, onions; dried carrots; red peppers; whole-grass fruit; whole wheat products of whole-grown grains; whole orange crops of oats and oats); whole grained cereals such as oats (oats, oats), oats or oats) and other oats.
Diets are divided into effects, opinions
In many forums, people who have used this type of alternative diet can find a lot of opinions. It is an effective diet, although not entirely due to the way it does not mix ingredients, and mainly due to a reduced calorie intake assumes about 1000 calories and additional physical activity. From a dietary point of view it is a diet that has no scientific proof of effectiveness. Moreover, it is shown to be a very poor diet and unreasonably composed in terms of product availability and macronutrient distribution (60% energy from carbohydrates, 30% from protein, 10% from fat).
