Seeds can give birth to life, indicating that seeds are very rich in nutrition. So what's in the grape seed? There are mainly phenols, polyphenols and resveratrol. There are many antioxidants in this seed. We know that people's aging, whether facial aging or visceral aging, as well as the aging of the body and the decline of this immune ability, are caused by the formation of free radicals. The main components of grape seed oil are linoleic acid and anthocyanin, and the linoleic acid content is above 70%. It can prevent and treat cardiovascular diseases, reduce human serum cholesterol and blood pressure, and its nutritional value and medical function have been fully affirmed by medical circles and nutritionists at home and abroad.
Not only the seed effect is remarkable, but also the grape skin. The natural pigment in grape skin has a good effect on lowering blood sugar and fighting cancer. The natural pigment content of dark grape is higher than that of light grape skin. Tannin, another important substance in grape skin, has the functions of anti-allergy, delaying aging and enhancing immunity. Therefore, "eating grapes without spitting grape skins" also has its scientific truth.
Among grape meat, grape skins and grape seeds, grape seeds have the highest nutrition, so they should be eaten.
2. Disadvantages
Generally, grape seeds are hard. If friends with poor spleen and stomach can't stand eating grape seeds, the digestive system sometimes leads to abdominal pain and bloating. Grape skins are not as hard as seeds, but they are not easy to digest. For example, China has huge peels and seeds. Although meat contains a lot of water, the skin is not very delicious, especially astringent, and the seeds are also very astringent.
The result of chewing grape skins and swallowing grape seeds can only be a numbness of the tongue, which makes me feel very uncomfortable and can't be recovered for a long time. This is because it contains a lot of tannins, which will coagulate protein on the surface of tongue, mouth and esophagus, and produce a strong astringent taste. This substance is the same as tannin in persimmon to some extent, and it is harmful to the digestive tract if eaten in large quantities.
3. How to eat grape seeds correctly
1, pay attention to the type of grapes. Rose fragrance skin is very thin, and the seeds are very small, so it can be eaten whole. If you buy a delicious and thin skin, such as Xinjiang seedless white, you can even eat with meat together.
2. Take the washed whole grape, put it into a juicer, and beat the whole grape into grape juice, so that the skin is broken and the seeds are broken, and the pulp composition is not particularly astringent, which is especially suitable for the elderly.
3. You can dry the grape seeds and mix them when making some snacks.
4. If you want to get the benefits of grape skins and grape seeds, chewing with your teeth, stirring with your tongue and extracting with saliva, the effect is quite unsatisfactory. A better way is to make your own wine. Friends who want to get health care ingredients may wish to try it themselves. Prepare a can of low-priced white wine first, tear off the dark grape skins such as rose fragrance and throw them in in large quantities. The grape seeds you spit out are smashed with a hammer or the back of a knife and thrown in. Cover and soak for 2 weeks, shake frequently. As time goes on, the color of grape skin becomes lighter and the color of wine becomes red. At this time, filter out the dregs, or remove the clear juice on it, and it will become a healthy wine with grape skins and seeds.
4. How to choose grapes
1. If the grapes grow too close, it will lead to insufficient illumination of the grapes, and naturally, the nutrients will also be affected. Therefore, when picking grapes, it is best to choose grapes that are not very tight and slightly loose.
2, this one on the tip is the latest to mature. If this one is delicious, everything else is delicious.
There is a layer of frost on the surface of fresh grapes, which will fall off when touched by hand, so the grapes without frost may be picked and kept, and the frost will fall off. What's more, green-skinned grapes can't see hoarfrost, so this method is not applicable.
4. The fresh grape stalks are tough, the stalks are relatively strong, and the ordinary stalks that have been in stock for a long time are crumbling.
5, smell it, the grapes that start to rot will produce the taste of alcohol.
6. There is no spot residue on the grape surface, which means that it has not been sprayed before harvesting, and there are few pesticide residues, which are not polluted by diseases and are relatively green and healthy.
