The first kind: salmon
What a surprise. Red meat salmon, which tastes super delicious, actually meets the needs of our taste buds and also provides good help for women's anti-aging. The secret is that the red meat of salmon contains a mysterious ingredient-Haematococcus pluvialis essence, also known as astaxanthin, which is the natural substance with the strongest antioxidant capacity so far.
How strong is the antioxidant capacity of Haematococcus pluvialis essence? Or speak with numbers-vitamin E is 1000 times! 20 times that of lycopene! 10 times of beta carotene! Grape seed 17 times! Anthocyanin 150 times! It is 200 times that of tea polyphenols and lutein.
! These substances used for comparison will appear in the foods introduced below and become the main factors of antioxidant capacity of different foods. It is precisely because of this precious essence of Haematococcus pluvialis that salmon will become the only meat in Time magazine's list of antioxidant foods. But don't go to the supermarket blindly, because the extract of Haematococcus pluvialis from wild salmon is far more than that from farmed salmon, so you must pay attention to the source of salmon when choosing.
The second kind: tomatoes
There is a joke that tomatoes are red and doctors are green. Although this statement is somewhat exaggerated, it tells the fact that tomatoes can really enhance the body's resistance, anti-aging, anti-oxidation, and especially keep women young. This is mainly because lycopene in tomatoes also has antioxidant capacity. This is supported by clinical data: a study of more than 47,000 men by Harvard Medical School in the United States shows that men who eat ketchup or other cooked tomatoes twice a week are 20% less likely to develop prostate cancer than men who eat less than twice.
It should be noted that lycopene is a fat-soluble carotenoid, so the effect of eating it raw is much lower than that of eating tomatoes with other seasonings after cooking. No wonder so many people like to eat scrambled eggs with tomatoes.
The third kind: mushrooms and other fungi.
When it comes to the antioxidant function of mushrooms, many people may not have heard of it. But what about ganoderma lucidum? This fungal plant appeared in ancient China with the title of "prolonging life", which has obvious anti-oxidation and anti-aging effects. You may not know that the main reason why mushrooms, like Ganoderma lucidum, have antioxidant capacity is that they contain a substance called polysaccharide. The antioxidant activity of polysaccharides is very stable, and whether it is heated at high temperature or in oxygen environment, it will not affect the performance of antioxidant capacity at all. In view of the problem of women's anti-aging, since Ganoderma lucidum can't afford it, women should buy more mushrooms to eat.
The fourth kind: green tea.
In fact, the effect of green tea is far more than our familiar deoiling and refreshing breath. It also has good anti-oxidation and anti-aging effects. Among them, tea polyphenols in green tea play a key role. But you know what? Although tea polyphenols have antioxidant capacity, they are particularly "delicate", and the most obvious performance is that they can't help being exposed to the sun. Because tea polyphenols are particularly sensitive to oxygen and light, as long as green tea is exposed to air or sunlight, the tea polyphenols in it will be quickly lost. Therefore, if you want to make full use of the antioxidant effect of green tea, you must drink sealed, dark and refrigerated tea. In this way, if it is too much trouble to seal and avoid light every time, the tea leaves in multiple sealed packages and disposable pouches are more suitable for "lazy people".
Carotene is very good for the retina of the eye, so many eye medicines add chrysanthemum as one of the ingredients, which is why. Marigold is the plant with the highest lutein content, and lutein sold in the market is mainly extracted from marigold. But lutein, like tea polyphenols, is also very sensitive, afraid of light and air, because the oxidation ability will be rapidly weakened by oxidation. Therefore, the correct drinking method of chrysanthemum tea is freeze-drying and dehydration, and then sealed from light. Those dried chrysanthemum teas have little antioxidant capacity.
The fifth kind: grapes
The antioxidant capacity of grapes and wine is mainly reflected in the anthocyanins in grape seeds. This substance has a strong antioxidant capacity, which is 20 times that of vitamin C and 50 times that of vitamin E. The antioxidant capacity of red wine made from grapes is further improved through fermentation. Therefore, drinking a glass of wine before going to bed is not only good for the quality of sleep, but more importantly, it can prevent the body from aging and keep young. But for people who eat grapes, they will fall into a "dilemma". Most of us spit out grape seeds when we eat grapes, but we don't know that the spit grape seeds are valuable substances for anti-oxidation and anti-aging. But if we chew grape seeds carefully when eating grapes, the strange taste will probably be unacceptable to many people.
This is also a reason why wine is more expensive than grapes: in addition to the extra labor costs, grape seeds will be added in the wine brewing process, and the fermentation process will further enhance the antioxidant capacity; Grape juice, as a kind of fruit or beverage, has less antioxidant and anti-aging components due to the lack of fermentation process.
The sixth kind: nuts
Nutritionists advise women to eat foods containing vitamin E, but in moderation, otherwise it will go too far. Why? This is because it has antioxidant and anti-aging functions, and can also repair skin tissues, including nut foods containing vitamin E, such as cashew nuts, walnuts, hazelnuts and peanuts. However, if you eat too much, you will also be in danger of getting fat. This is because nut foods contain high fat, and the oxidation reaction caused by high fat will also destroy the antioxidant effect of vitamin E.
The seventh kind: garlic
Garlic is a typical "ugly on the outside and beautiful on the inside" antioxidant food. Say it is ugly, first, it looks plain and has no bright colors; Second, the taste of garlic is really pleasing; It is beautiful because the sulfide contained in garlic has antioxidant and lowering effects, which can not only effectively lower cholesterol in the body, but also prevent hypertension and cardiovascular diseases. Not only has anti-oxidation and anti-aging effects, but also has the functions of promoting blood circulation and accelerating metabolism, which can help detoxify and lose weight!
Eighth: Blueberries
New research shows that red, purple and blue fruits, including blueberries, blackberries and black grapes, will become antioxidant foods in 2 1 century. These foods are rich in anthocyanins and have strong antioxidant capacity. Anthocyanin is a powerful antioxidant nutrient. If you can't eat fresh blueberries, you can try canned or frozen blueberries. Anthocyanin has been proved to prevent collagen from decomposing. This protein is mainly concentrated in the skin, joints and blood vessels, and is responsible for delivering nutrients to the brain and maintaining the elasticity of the skin. Once this protein is decomposed, the human body will gradually age.
In terms of antioxidant capacity, anthocyanins are more than 50 times stronger than vitamin E. Anthocyanins are blue-purple in alkaline conditions and red in acidic conditions. Many fruits and plant foods contain purple and red anthocyanins.
It's anthocyanin.
Ninth species: marigold
Everyone must have drunk chrysanthemum tea. We have a tradition of drinking chrysanthemum tea to improve our eyesight. But why can drinking chrysanthemum tea improve your eyesight? The reason is that chrysanthemum contains lutein, a strong antioxidant. Although its antioxidant capacity is not as good as Haematococcus pluvialis essence contained in salmon, it is a carotenoid, which can penetrate the blood-brain barrier like the latter and is very good for the retina of eyes. Therefore, chrysanthemum as an ingredient is added to many drugs for treating eyes. Marigold is the plant with the highest lutein content, and lutein sold in the market is mainly extracted from marigold. But lutein, like tea polyphenols, is also very sensitive, afraid of light and air, because the oxidation ability will be rapidly weakened by oxidation. Therefore, the correct drinking method of chrysanthemum tea is freeze-drying and dehydration, and then sealed from light. Those dried chrysanthemum teas have little antioxidant capacity.
Tenth species: grapefruit
The antioxidant capacity of grapefruit is mainly reflected in its rich bioflavonoids, which are a powerful antioxidant component and can be combined with toxic metal substances to drive these poisons out of the body. Bioflavonoids also help to make vitamin C more stable in human tissues and help to play an anti-inflammatory and anti-cancer role. The content of bioflavonoids in fruits is high, which is also helpful for human body to absorb. The molecular weight of this flavone is relatively small, and it can be absorbed in the intestine without further hydrolysis, so it will not be easily destroyed, and it can better maintain its original morphological characteristics and play a role in the body.
