Potato

It is the season when it is delicious in new in spring. Speaking of a "potato", those who remember having grated and having taken out "starch" in the experiment of the science of an elementary school may also require it. However, the nutrient contained in the potato is not only carbohydrate.

a potato -- two kinds of carbohydrates, essential fatty acid, eight kinds of essential amino acids, 13-14 kinds, and almost all vitamins and about 20 kinds of minerals -- and very abundant nutrients are included. Nutritive value is so high that it can make a living even if it continues eating only it if it goes too far in saying.And the point that the work to which the carbohydrate contained in a potato protects vitamin C from heat can also take enough the vitamin C which tends to be lost by heating for a certain reason is also a merit. If history is gone back, it comes to eat a potato and it is said in Scandinavian countries that scurvy by the shortage of vitamin C was lost.It is also clear that potatoes are foods which are very easy to acquire a feeling of fullness. "The SATIETY index (substantial index)" which the research consortium of the Sydney university developed is what ranked and carried out relation of the amount of calorie consumption, and satisfaction. There is much quality of a fiber, and since a feeling of fullness is early acquired for food with a lower calorie considering quantity, a substantial index becomes high considering.The value of 323 of the boiled potato was the highest in among the many foods. Even if compared with about 3 times of "spaghetti" and "bread", the "policed rice", and the "brown rice" which are the foods of other staple food classes, they are about 2.5 times and a value high to leading by a wide margin.This is considered because there is an action which makes a potato secrete the full stomach hormone "KORESHISUTOKININ." A feeling of fullness continues by this action for a long time. Even if it thinks the "belly eight-tenths", a potato can be said to overweight prevention of those who eat too much just as the optimal foods.However, since he cannot eat a potato in the flesh compared with other vegetables, it has the image which requires time and effort for cooking. Moreover, if potato fly, baked potato, etc. seem to have the high calorie in order to use oil for cooking in many cases, those who have avoided will also have them.To be sure, in the case of "baked potato", "the Glycemic index (GI)" which shows the ease of going up of the blood sugar level after a meal is 93. If this compares with 41 of "spaghetti", 76 of "brown rice", etc., it serves as a quite high value.GI sets the amount of rises of the blood sugar level in 2 hours to 100, after taking grape sugar, and it calculates it as compared with the amount of rises of the blood sugar level at the time of taking the food with which the sugar of the amount of said is contained. Since a potato is soft and digestive absorption tends to be carried out in a top with abundant carbohydrates, a numerical value becomes high.But since 75-90, and "policed rice" are 86-98, GI of "white bread" can be said to be baked potato and a value practically equal. And GI of "the boiled potato" becomes low to 78 to about 88. And just it is devised be each other olive oil after boiling, it will not be necessary to care so much.Moreover, in fact, the potato of the calorie per gram is also low, and is set to about 1/3 of bread. It is just good if it is substantial at low calorie content, a price is also cheap and it will come. How about taking [ it not only adds a potato to one article of a dish, but ] in it to the leading role of a table well?For example, the potato egg omelette into which many boiled potatoes and onions were put becomes also instead of the staple food. It is the tips which a potato is exactly seasoned with salt and pepper, and are firmly roasted with full olive oil.
