Drinking grapefruit green tea can greatly improve your weight loss ability? Doctor: Mother soup~ Be careful of these risks

Many people try to lose weight by eating fruits. Among them, the most popular fruit is probably grapefruit, which is known as the "holy fruit for weight loss." In the past, grapefruit was misleadingly regarded as a negative-calorie fruit, which attracted many beautiful girls. Some people even added grapefruit to green tea to double the weight loss effect, and regarded grapefruit green tea as a magic drink for weight loss. Is this drink really that magical? Let’s hear what a weight loss specialist has to say.

Grapefruit is known as the "holy fruit for weight loss" because it is relatively low in calories and high in dietary fiber.

Why is it said on the Internet that grapefruit is the "holy fruit for weight loss"? Liu Boen, executive director of the Taiwan Obesity Education and Prevention Association and a weight loss specialist, said that according to the Food Nutrition Database, every 100 grams of yellow-skinned grapefruit has about 36 calories, making it one of the relatively low-calorie fruits, second only to guava at 32 calories, and the two are almost on par; and the dietary fiber content of grapefruit is about 1.1, which is actually second only to fruits such as guava at 3.6. One grapefruit contains about 10 grams of fiber, which is helpful in improving constipation.

In addition to being relatively low in calories and high in dietary fiber, grapefruit is also rich in vitamin C. Grapefruit juice also contains rich potassium ions and folic acid, which have the auxiliary effect of helping to stabilize blood pressure and reduce vascular hardening. Another ingredient is that grapefruit contains unique pectin, which helps lower cholesterol and increase satiety. Therefore, many female celebrities claim that they have successfully lost weight by drinking grapefruit juice, thus making grapefruit, like lemon, an undefeated star in assisting weight loss.

Grapefruit can reduce the detoxification ability of the liver and should not be used together with lipid-lowering drugs or cardiovascular drugs.

However, it should be noted that grapefruit contains flavonoids and coumarins, which can inhibit the liver's hormone metabolism of drugs, making it impossible for drugs to be excreted from the liver, thereby reducing the availability of drugs. Therefore, some drugs such as epilepsy drugs, lipid-lowering drugs, cardiovascular drugs, and psychiatric drugs should not be taken with grapefruit as much as possible, because grapefruit will reduce the detoxification ability of the human liver, that is, it will delay the decomposition of drugs, allowing a large amount of drugs to accumulate in the human blood, which can easily cause poisoning due to excessive drug concentration.

Every 100 grams of yellow-skinned grapefruit contains about 36 calories, making it one of the relatively low-calorie fruits.

Tea and grapefruit should not be consumed together, especially by patients with cardiovascular diseases.

It is common to see tea shops adding grapefruit to green tea to make grapefruit green tea drinks. People who like to drink it believe that it can achieve the effect of 1 plus 1 being greater than 2 for weight loss. Dr. Liu Boen said that drinking green tea to lose weight has been popular for some time. The theory is that tea contains catechins, which are a type of plant flavonoids that have anti-free radical and anti-inflammatory effects. Therefore, some literature reports point out that this ingredient has the function of protecting the cardiovascular system, and its other function is to act like a sympathetic nerve promoter, which will speed up our heartbeat and indirectly increase the metabolic rate slightly.

Excessive consumption of green tea may cause palpitations, insomnia, hand tremors, and duodenal ulcers

Therefore, many people who want to lose weight use this feature as a weight loss aid. However, many people who want to lose weight tend to drink green tea in large quantities, in excessive amounts, and in a short period of time, thinking that the more and stronger the tea leaves are, the better the effect will be. In fact, in addition to causing palpitations, insomnia, hand tremors, and hyperactivity, excessive tea drinking can also lead to side effects such as duodenal ulcers. Therefore, green tea drinks cannot replace the role of boiled water.

Grapefruit and green tea for weight loss: 1 plus 1 is greater than 2? Doctor: Be careful of hyperkalemia

As for some common beverage shops in the market, in order to increase the appeal effect, they often add some grapefruit, yogurt, etc. to green tea. However, there are still so-called incompatibility principles between foods. For example, tea and grapefruit should not be used together, especially for patients with cardiovascular diseases, because tea has a diuretic effect, which will cause the body to excrete sodium ions, and the potassium ions in grapefruit will also cause sodium ions to be lost. Both will make the potassium ions too high and produce hyperkalemia. In addition to damaging kidney function, in severe cases, there will also be numbness of fingers, muscle weakness, and even arrhythmia. In severe cases, there will be side effects such as ventricular fibrillation.

If you like drinking tea in the summer and want to enjoy the health benefits of tea, Dr. Liu Bowen recommends adding something such as honey, lemon, etc. to the tea. This can not only dilute the bitterness of theophylline, but also provide rich vitamin C, achieving a beauty effect, which can be said to kill two birds with one stone.
