Мавка, а у тебя есть ссылки на достоверные источники, что обезжиренные продукты полезные? Любой нормальный человек скажет, что чем натуральнее продукт, тем он полезнее. Это не требует доказательств, это аксиома (только если нет какого-то заболевания, требующего специальной диеты).
Are all kinds of fat equally healthy?
Willett: Some types of fats are healthier than others. Unsaturated fat is the healthiest type of fat. Plant oils, such as olive, canola, corn, peanut and other nut oils; nuts, such as almonds, peanuts, walnuts, and pistachios; avocados; and fish, especially oily fish such as salmon and canned tuna, are excellent sources of unsaturated fat. Eating unsaturated fat in place of refined grains and sugar can improve blood cholesterol profiles and lower triglycerides, and in turn, lower the risk of heart disease.
It is essential to include a special kind of unsaturated fat, called omega-3 fats, in the diet; good sources include fish, walnuts, flax seeds, and canola oil. Keep in mind that omega-3 fats from marine sources, such as fish and shellfish, have much more powerful health benefits than omega-3 fats from plant sources, like walnuts and flax seeds. But omega-3 fats from plant sources still are a good choice, especially for people who don’t eat fish.
Saturated fat is less healthy, since it raises “bad” cholesterol in the blood. We can’t completely eliminate saturated fat from our diets, though, because foods that are rich in healthy fats also contain a little bit of saturated fat. The best strategy is to limit foods that are very high in saturated fat, such as butter, cheese, and red meat, and replace them with foods that are high in healthy fats, such as plant oils, nuts, and fish. An alternative approach is to just use a very small amount of full-fat cheese, butter, cream, or red meat in dishes that emphasize plant foods such as vegetables, whole grains, and legumes.
Whatever you do, don’t replace foods that are high in saturated fat with “fast carbs”—foods like white bread, white rice, potatoes, sugary drinks, and refined snacks—since eating too many of these fast carbs is just as bad for your heart as eating too much saturated fat.
Trans fat from partially hydrogenated oil (oil that has been chemically processed to make it more shelf-stable) is especially bad for health. Eating just a small amount of trans fat on a regular basis raises the risk of heart disease. So it’s best to avoid trans fat altogether. Most of the trans fat in people’s diets comes from commercially prepared baked goods, margarines, snack foods, and processed foods. Many food makers are cutting trans fats from their products and replacing them with healthier fats. Still, you’ll need to scan Nutrition Facts labels to make sure that the food you eat is free of trans fats.
Keep in mind that most foods contain a mix of fats. The key to a healthy diet is to choose foods that are higher in unsaturated fat than saturated fat—and that do not contain any trans fat. When you cut foods like red meat and butter out of your diet, replace them with healthy plant oils, nuts, fish, vegetables, or whole grains—don’t replace them with white bread, white rice, potatoes, or other refined carbohydrates.
