7 healthy grapefruit benefits you should be aware of
The benefits of grapefruit for the human body
Grapefruits have long been known for their beneficial properties in losing weight, and therefore are most often associated with diets that help to lose weight. There are many ways to include them in a healthy diet, for example, half a grapefruit with boiled egg for breakfast or a grapefruit diet (a serving of this fruit with each meal speeds up metabolism and weight loss). And if earlier talk about the benefits of grapefruit was often perceived as another myth, today its many of its properties are scientifically proven.
The benefits of grapefruit for men and for women are several. In men, the rate of elimination of itraconazole was similar to that taken with grapefruit juice or water. However, in women, grapefruit juice caused a sharp decrease in the rate of excretion from their blood serum. Doctors warn that people should avoid grapefruit juice altogether when taking calcium channel blockers, which can reach levels of 100-150% higher than usual, which leads to a rapid decrease in blood pressure.
There is an assumption that grapefruit can directly increase estrogen levels in women. In men, grapefruit can increase the body’s production of aromatase, an enzyme that turns testosterone into estrogen in men.
The huge amount of nutrients in grapefruit allows you to recommend it as a necessary product for the diet of pregnant women.
What is the use of grapefruit for the human body, in addition to losing weight?
The nutrient content of grapefruit is impressive: 100 g – 42 kilocalories, 1 g protein, 31 mg vitamin C (50% of the recommended daily intake), 13 μg folic acid, 135 mg potassium, 22 mg calcium, 9 mg magnesium, 2 g fiber Vitamins B1 and B6. And this is along with a long list of antioxidants. Grapefruits are not only good for their refreshing taste, low in calories and carbohydrates (which will help curb your appetite, so you can try to eat it before meals if you tend to overeat). In addition, it lowers blood sugar, is rich in antioxidants and contains 77 mg of vitamin C per serving. All this helps maintain your overall health and immune system.
What is the difference between white and red grapefruit?
Pink and red varieties contain carotenoids – lycopene and beta-carotene, in addition to all of the vitamins and antioxidants listed above. Eating red grapefruit can help lower triglycerides in patients with coronary atherosclerosis. Therefore, the beneficial properties of red grapefruit can be called simply amazing.
Effective for weight loss
In a study conducted by the Nutrition and Medical Research Center at Scripps Clinic in San Diego, 90 people were divided into 3 groups.
The first group ate half of grapefruit before each meal three times a day. The second group drank grapefruit juice before each meal three times a day. The third group did not eat grapefruits.
No other changes to their diet have been introduced. The results showed: participants from the first two groups lost an average of 1.5 kg over 12 weeks, while in the third group, the participants retained their previous weight. Scientists also noted in people in the “grapefruit” groups a lower level of insulin in the blood, which was associated with increased weight loss. The benefits of grapefruit for weight loss have been successfully proven.
Grapefruit contains antioxidants such as naringenin, they improve insulin sensitivity and help maintain a healthy weight. Scientists have found that naringenin stimulates the liver to burn fat, rather than store it. It has also been found that grapefruit helps lower insulin levels as effectively as metformin.
When insulin sensitivity is high and the body controls blood sugar levels, cells become more susceptible to substances coming from food. Thanks to this, everything that we eat is more efficiently burned as fuel. And this contributes to a healthy appetite.
Thanks to the soluble pectin fibers in grapefruit, this fruit removes cholesterol through the intestines. A study at Hebrew University in Jerusalem showed that one red grapefruit every day for 30 days lowers LDL cholesterol by 20.3% and triglycerides by 17.2%. And yellow grapefruit in the same mode reduces LDL by 10.7% and triglycerides by 5.6%.
Thanks to antioxidants and potassium, grapefruit helps maintain vascular dilatation, modulates blood sugar, stimulates weight loss, and also lowers LDL cholesterol and triglycerides. All this works to protect the heart.
The acidity of grapefruit helps maintain bile formation, and when combined with fiber, it improves digestion.
