Not for nothing they say, new – well forgotten old. The Hollywood grapefruit diet was invented back in the 1930s of the last century. As the name suggests, the basis for the proposed method is to quickly and effectively lose weight – intensive use of grapefruit or, as they are called, “heavenly citrus”. And also other products, in particular, chicken eggs.
Where did the grapefruit come from?
Some believe that grapefruit is the result of artificial breeding, the so-called hybrid, the combination of orange and lemon. In fact, this is not so. They were first discovered on the island of Barbados in the middle of the 18th century. It is believed that this is the result of natural hybridization of pomelo and orange , and related relationships with pomelo are much closer than with orange.
Fruits grow on a tree up to 12 meters high. They are large, weighing from 150 to 500 g. The rind is tightly attached to the pulp. The pulp is juicy, yellowish or reddish. The fruits are sweet, but bitter.
Because of the characteristic arrangement in the form of grape bunches, grapefruit was called a combination of the words “grapes” ( grape ) and “fruit” ( fruit ). This property is also reflected in the scientific name – “pompelmus groinlike.” From Latin Citrus paradisi translates “heavenly citrus”.
Natural varieties are grown in the subtropics – in Cyprus, in Israel, in the USA. Specially produced frost-resistant varieties grow in Georgia. All varieties of plants, and their order of two dozen, depending on the color of the pulp are divided into “yellow” and “red”.
Useful properties of grapefruit
Diet with grapefruit is not only used for weight loss. Fruits contain a lot of nutrients. First of all, they have a lot of vitamin C, as well as vitamins A, B1, D, P, various sugars, organic acids and mineral salts, pectins.
Pectins help lower cholesterol levels. It is proved that to reduce cholesterol it is better to use “red” varieties. At the same time, harmful substances are removed from the intestine. The effectiveness of pectins is enhanced by citric acid.
Useful properties of grapefruit are manifested by a high content of phytoncides – natural antibiotics, as well as naringin , stimulating metabolic processes, digestion and at the same time giving a bitter taste. Naringin is found in films that separate the fetal lobules.
Of course, if you want to eliminate the bitterness, you can clean the film from the lobules. But in this case, you will not be able to lose weight and get rid of excess cholesterol.
Suffering heart diseases in order to normalize the ratio of “good” and “bad” cholesterol for preventive purposes it is useful to adhere to a diet of one grapefruit, consumed 2-3 times a week for breakfast. In other respects, the food remains the same. Diet on grapefruit juice because of the low content of medicinal naringin will not give a result.
