The truth is like this. Potatoes are vegetables in the highest heat, because it contains starch. However, its water content as high as 76% above, the real starch content less than 20%, still contain among them can produce "satiety" "fiber", so use them to replace staple food have effect reducing weight.
One, then why potatoes also by many people as a fattening foods?
1, improper because people cooking, French fries, potato chips of potato make it make it when everything. Done "potato roast pork" people know that the potato oil absorption ability is very strong. According to the determination, a medium size not drain the French roast potatoes only contains about 90 kilocalorie quantity of heat, and the same after the chips of potato contains heat of 200 kilocalorie above. Not visible, fattening of potato itself, but it absorbs the oil.2, because people didn't use potatoes to replace staple food, but think of it as a dish. Potatoes contain fewer calories than staple food, more than general vegetables. If using potato as soon as the food, should be appropriate to reduce the number of staple food. If no less staple food, the result is - tend to get fat eating potato food than to eat green vegetables.
Second, in fact, from a nutritional value standpoint, the potato is a kind of good food.
First of all, its content of potassium, magnesium, higher than that of white rice and white flour, is a kind of alkaline food. All the white rice flour and partial acid constitution. Second, the potato protein is of high quality. Although the protein content is only 2%, but which is rich in lysine, as long as the number of eat more than enough, can let a person get body needs many kinds of amino acid. Third, potatoes contain vitamin C, it is white rice flour is not a good thing. Fourth, potatoes contain prandial fiber, and white rice flour fiber very few. Potato fiber texture soft, does not stimulate intestines and stomach, all kinds of people can eat. Gastric ulcer or inflammatory bowel disease can safely eat potatoes.Three, however, from the point of view of food safety, the potato is not a good snack.
Originally, potatoes after high temperature heating, particularly easy to form the acrylamide class toxic substances, so the chips is the highest levels of food poison, fries also have this kind of trouble. So, potato chips, Fried slices, such as French fries snacks take extra care, not more than 25 grams per day.Fortunately, home-style cooking Fried stew of heating temperature not to exceed 120 degrees, so will not produce any harmful substances. So, potatoes, Fried potatoes and steamed potatoes are safe to eat, just to note that eat them, will be less food.
