Raw tomatoes in the end good or bad 不指定

So may have a lot of debate: is eating cooked tomatoes such thing as a waste of one of the vitamin C; tomato raw is no free ride, does not absorb lycopene. Thus, consumers face the tomato is really too difficult for the left and right is also difficult. What how to eat best? May wish to see the foreign study results.

Among the vegetables, tomato is a very different species. It can be a fruit, it can be a vegetable. While Westerners are accustomed to tomatoes, tomato sauce and tomato sauce to cook, but most Chinese people are like cold or raw. Especially the deep red of the market, "cherry tomatoes" and orange red tomatoes, is basically used for fruit eaten raw.

So may have a lot of debate: is eating cooked tomatoes such thing as a waste of one of the vitamin C; tomato raw is no free ride, does not absorb lycopene. Thus, consumers face the tomato is really too difficult for the left and right is also difficult. What how to eat best? May wish to see the foreign study results.

United States, the University of Iowa researchers found a group of graduate students to do subjects to enable them to eat a bowl of vegetable salad with tomatoes, but were different salad dressings. Researchers to their veins, even on a small plastic tube to collect blood samples before and after meal time for the determination.

The students feel, the kind of salad dressing all about, anyway similar taste. However, in practice very different from the content of salad dressing, some 80% of the normal fat containing salad dressing, some low-fat salad dressing, some simply use the fat substitute, can absorb the fat content is zero.

However, the determination of the result is quite different. Only eat when traditional salad dressing, blood lycopene, carotene, lutein and other useful elements will significantly increase, with low fat or fat substitute salad dressing when the very poor. Thus, the researchers said that while raw vegetables are fashionable, non-fat cooking is also very fashionable, but when eating vegetables deep color, a little oil is good.

However, this regret is not no way to compensate. The researchers said that as long as adequate chewing, chewed some, cut into Unqualified, or rub broken into the end of the absorption of carotenoids can be increased, as long as cells are damaged, which can easily run out of carotenoids. From this sense, the labeled carrot paste, even though the loss will be severely vitamin C, there is help absorb the carotenoids.

Spanish scientists published in the "Journal of Food Science" on a very detailed study. They were determined using 20 kinds of vegetables, 6 kinds of cooking methods, compare the loss of antioxidant levels. Surprisingly, in the cooking, the carrot instead of the antioxidant effect of an increase. Peas, garlic and beet cooking no matter how the loss is small. The results showed that the best preserved antioxidant microwave cooking is cooking, and boiled and the greatest loss of high-pressure cooking. This is not because of pressure cooking and cooking temperature is too high, but because cooked suck, most of the antioxidants are integrated into the water dish inside but the results have less. After a lot of people will be the cook in the cooking water thrown away, so that nutrients and antioxidants will be lost. If even with the water to eat, a very small losses.

This is a very good news. Those with foreign or raw, or cook a rare bus rotten cooking methods, people or Cheuk mix, or stir-fry or stew of vegetables and cooking habits and Coptis, vegetables will not bring too many antioxidants loss .

However, it is completely without having to adhere, "how to eat the best" argument. Personally think that as long as you like, but more oil, heating temperature, but high, his favorite, is the best cooking methods. Because, even if some of the loss, even if the absorption rate is not satisfactory, can make it up as long as eat some. Those who did not lose the nutrients, such as potassium, such as fiber, we will get more. Those people eat to swallow, even if it seems there is no loss of nutrition, the end result or eat too little.

So, if want to raw tomatoes as fruit or juice to drink it labeled, are completely without any worries. The point is, whether the stomach after eating cold, whether diarrhea. If there are no such problems, then according to their appetite to eat.
