Middle of winter, and in a lot of stores of fresh vegetables and fruits, home inventory - a lot of pickles and preserves. But are all the gifts of nature are now useful? Because of our harsh climate in the nation has developed two myths. The first was born in the era of the Soviet deficit: Fresh fruits and vegetables can be eaten only in the season, and at other times of the year - better than homemade stocks - pickles, jams, compotes. The second myth sounds more scientific: if our ancestors ate only what was mined in their native lands, the person's metabolism is closely associated with the area of residence. Since the winter of fresh gifts of nature did not exist (and the more tropical), then they are harmful to us.
Taters - not our
- If you think so, first of all, we must not give up on bananas and citrus, and the main national product - potatoes - explains Victor Konishev, an expert on nutrition, MD. - It started to plant, as well as coffee, just under Peter I, for a total of 300 years ago. From the point of view of the evolution is the infinitesimal interval of time during which no metabolic adaptations to the product can not occur.
On the other hand, even if you eat only what bring your 6 acres, then this power will not be perfect. Why?
- Experts from the World Health Organization (WHO) recommended for the prevention of diseases every day not less than 400 g of vegetables, fruits and berries - explains Victor Konishev. - Each fruit is endowed with peculiar only to him nutrients, so it is best to combine different gifts of nature. Cranberries, for example, the content of vitamin C gives black currants, sea buckthorn and kiwi. But there is a lot of resveratrol (which protects against atherosclerosis). Seabuckthorn and avocado, unlike other fruits contain a lot of useful unsaturated fatty acids. It is often assumed, though fruit - the source of all the vitamins. But it is not. In general, they contain only vitamin C, folic acid and beta-carotene (Vitamin formed from it A). The need for other vitamins to make up for the expense of animal foods and cereals. For example, in the winter we are especially important vitamin D - for its production in the body is not enough sun. In the fruits of this vitamin is not, fill a need for it will help the eggs, butter, cod liver oil, eggs.
On the recommendation of the WHO, many countries have conducted information campaigns to promote vegetables and fruits. If Russia had heard this call, the slogan we would read as follows: "5 times a day". This means that everyone needs to eat in a day at least 5 servings of fruits and vegetables, each serving - 80-100 grams. However, in some countries, the recommended dose increased up to 6-12 times a day. In addition, people were taught to eat the fruit of different colors. "The Game" in color has a serious scientific basis - the color of fruits and vegetables give useful substances with potent antioxidant properties. They protect us from diseases of the heart, blood vessels, even many cancers.
Live without pineapple?
What to look for when visiting a store?
# 10004; carrots, beets, cabbage, turnips, radishes and onions - the only Russian vegetables, continuing through the winter without conservation. But they are not enough. Need more tomatoes, colored peppers, zucchini, eggplant, lettuce and tomatoes, etc. can be replaced with tomato juice.
# 10004; domestic fruits do not survive the winter. So do not shrink from gifts from warm. Of course, without the pineapple and mango can do. But the usual oranges and tangerines body needs.
# 10004; pickles, jams and compotes - is no longer useful gifts of nature, and ... to put it mildly, their imitation. But there is one exception - the sauerkraut. However, it is not correct to refer to the salt, and to products like yogurt and fermented wine. After fermentation, the nutrients from it digest better. When cabbage they are partially destroyed.
# 10004; Summer berries, fruits and vegetables freeze in the freezer. Thus, in contrast to the jams and pickles, preserved nutrients. It is not necessary to consider the strawberries and cherries seasonal delights - they are useful all year round. But pickles, on the contrary, to the rank of special goodies - it's really yummy, but it is better than less often.
# 10004; dry, add a pinch of herbs in different dishes. According useful properties, it is not inferior to fresh.
# 10004; Potatoes - almost the only plant product that is not considered useful. Vitamins, antioxidants, and other relevant materials in it, "a cat laugh," and a lot of starch. Replace it with vegetable side dishes.
# 10004, can not say about greenhouse vegetables and herbs grown by hydroponics - in pots or artificially simulated soil. Of course, the ground is better. But these will fit.
Avocado, like gloves?
In fact, the bad fruits and vegetables does not happen - there are only individual contraindications to them.
- For example, an allergy to citrus. It often happens in early childhood, so breastfeeding mothers should avoid these fruits, - continues the story Konishev. - Many people like to reduce chokeberry blood pressure. But because of the high content of vitamin K, these berries improve blood clotting, which is undesirable for the elderly, and in fact they often suffer from hypertension. Such a feature is important to consider chokeberry and those who take medications that lower blood clotting (warfarin and other vitamin K antagonists), their usual dose may be ineffective. In many diseases of digestive system not suitable acidic fruits. People with allergies to latex glove material due to the similarity of latex protein with a protein of some fruits often found the same reaction to avocados, pineapples, bananas, melons, figs, kiwi, papaya, peaches, tomatoes and chestnuts.
