do not know when start, people start food nutrition has been a model of view. Referred to certain nutrients, must make people think of certain foods, and certain foods that tend to make people think of some nutrition-related components.
For example, one said that vitamin C, people immediately think of lemons and oranges; one that potassium, people would immediately think of the banana; 1 Speaking of carotene, people will certainly think of a carrot; one that spinach, will immediately think of oxalic acid; one mentioned celery, would immediately think of lower blood pressure ... ...
In fact, the health of the role of food, should not this model are of. A lot of the food's nutritional truth will make us very surprised! Do not believe it? See below some examples of the nutritional value of food:
1 Who is the winner potassium in food?
taro contained in potassium, bananas and more than 50%. In fact, all the tubers are an excellent source of potassium. As long as the big bowl of rice put into the same starch content of potatoes, intake of potassium can be increased by 10 times!排尿量larger person, such as diabetes, kidney stone patients, gout patients, hypertensive patients, as well as people eat too much salt, it is easy to excessive loss of potassium, eat potato alternative staple food is a good idea.
In fact, green leafy vegetables, the potassium concentration of more than bananas abound, such as spinach, kale, leaf lettuce, water spinach, amaranth, Gynura such. Now that Chinese people eat to the species-rich绿叶菜, why must want and do not like green vegetables, like the Westerners do resort to bananas?
2 really good sources of magnesium
magnesium for strong bones, control blood pressure are important, but also as the "anti-stress nutrients." When it comes to magnesium, however, people will usually think of bananas. In fact, it is merely the fruit of magnesium only winner. Almost all dark green leafy vegetables are good sources of magnesium, the content be able to meet or exceed the level of banana. The reason is simple: each of the chlorophyll molecules which contain a magnesium ion, so the more the color green, the more magnesium.
Another best source of magnesium are nuts and seeds category, such as eating 50 seeds Kersee, it is equivalent to eating 200 grams of绿叶菜magnesium. However, green leafy vegetables, bananas, only one-third of calories, about one twentieth of nuts. Therefore, if怕胖words, eating potassium and magnesium supplement绿叶菜best selection.
3 do not eat fruits and vegetables can also add vitamin C?
generally think of tomatoes are vegetables, vitamin C leading, in fact, potatoes contain vitamin C than tomato also many ! Not only potatoes, sweet potato, taro, yam tubers and other foods contain a lot of vitamin C. Among a variety of green leafy vegetables contain vitamin C, almost all over tomatoes.
green vegetables are indeed of vitamin C winner, but it is relatively low acidity, vitamin C loss in the cooking which is relatively large. Even though the vitamin C content of potatoes is only one-third of green pepper, but because of starch of vitamin C with a strong protective effect, potatoes in the cooking process of vitamin C losses are small. Therefore, if using potatoes make the staple food, even if no longer eat other fruits and vegetables, vitamin C is also able to meet the needs of the human body. Northerners miss a meal over the past winter vegetables, a lot of people do not lack vitamin C, because they often use potatoes and sweet potato as the staple food.
summary:
to know the nutritional value of food must not only remember some the so-called "representatives", in fact, a lot of the nutritional value of food is not bad than they did, but no more than less well-known. Therefore, a healthy diet do not have to rigidly adhere to a certain food, the most important thing is a reasonable mix of various kinds of food. A food you do not like, can be used to replace other foods. - This is not a more relaxed, more happy?
