Like grapefruit, there are pitaya, which has white heart and red heart. The difference in nutrition between the two is that the red heart will contain more betanin and anthocyanin, but the price will be higher than that of the white heart.
Therefore, there is no need to buy expensive red pitaya. What about grapefruit?
The difference between these two kinds is mainly that the grapefruit with red heart contains lycopene and carotene. The former may not be familiar to everyone, but in fact, this substance will also exist in tomatoes that we often eat.
Only when tomatoes are cooked will they be rich in lycopene. If they are eaten raw, it is not easy to play them out. If they are cooked, they can. In related research, it is found that if it is lacking in the body, it will increase the incidence of prostate cancer, bladder cancer and gastric cancer to a certain extent.
Moderate consumption is very good, and then look at the latter, which I believe everyone is very familiar with. Carotene exists in general orange foods, such as carrots, pumpkins, colored peppers and so on.
It is an important nutritional component of skin and mucosa, and it also plays a very good role in protecting eyesight. If it is left, the grapefruit with white heart is almost the same as the grapefruit with red heart, especially the content of water and vitamin C is very high. In autumn, when the skin is easy to dry and the water in the body is easy to be insufficient, you can eat some grapefruit.
In addition, grapefruit has another benefit that everyone can't imagine. Don't throw away the grapefruit peel when eating, and use it to boil water to drink. Naringin is also contained in the grapefruit peel. In related research, it is found that this nutrient can prevent cardiovascular and cerebrovascular diseases, oxidation resistance, anti-tumor and anti-cancer effects.
But this kind of health food is bitter to eat, so you might as well put some honey, which will taste similar to honey grapefruit tea.
Therefore, for grapefruit with red heart and grapefruit with white heart, you don't have to pay too much attention to the nutrition of grapefruit with red heart. Its advantages can be taken from other foods, such as lycopene in grapefruit with red heart, tomatoes, and carotene in grapefruit with red heart, and carrots, so there is no need to buy grapefruit with red heart at high price.
Buy white heart grapefruit. Of course, you can choose according to your own conditions and preferences.
