Grapefruit: benefits and harm to the health of the body, use for weight loss

Improving the functioning of the immune system, accelerating metabolism, eliminating toxins - these and other qualities are possessed by grapefruit, BZHU and whose calorie content is so low that a person on a diet can consume it without fear of gaining weight. Tropical fruits contain many useful substances. Their use is recommended for elevated blood pressure, cholesterol, and glucose levels.

BJU fruit

BJU is the amount of nutrients contained in a product, which include proteins, fats and carbohydrates. They are important for the body because they participate in the construction of body tissues. The nutritional value of a product is determined by another parameter—calorie content. The KBJU of grapefruit is reflected in the following table:

Protein, entering the body with food, breaks down into amino acids. These substances are necessary for the growth and strengthening of muscle mass and other tissues. Proteins are also responsible for other body functions, for example, regulating the functioning of the immune system. The daily protein requirement depends on body weight, type of activity and other indicators. The average norm is 1-1.5 g per 1 kg of weight. With a lack of nutrients, metabolism is disrupted, the condition of hair and skin worsens, and performance decreases.

Fats are a source of energy. They are especially important for those who engage in physical labor. The daily intake of fat is 1-1.5 g per 1 kg of human body weight.

Carbohydrates, like fats, are a source of energy. They are necessary for those who engage in mental and physical labor. The need for these substances is 0.4-0.5 kg per day. Their deficiency leads to disruption of metabolic processes in the body and weight gain.

Composition and calorie content

Grapefruit is rightfully considered one of the healthiest fruits. It is enriched:

• various acids (nicotinic, folic, ascorbic, pantothenic);
• retinol;
• riboflavin;
• B vitamins;
• pyridoxine;
• tocopherol;
• naringin;
• beta-carotene;
• microelements (potassium, ferrum, calcium, magnesium, sodium).

Compared to orange, which is beneficial due to its high content of ascorbic acid, grapefruit is the most beneficial because it also contains a significant amount of natural sugars.

Nutritional value of grapefruit per 100 g:

• fats - 0.2 g;
• carbohydrates - 8.7 g;
• proteins - 0.8 g.

Grapefruit has a low calorie content, which makes it possible to consume it during a diet. The energy value of fruit per 100 g is 35 kcal.
At the same time, pink grapefruits have more calories than white ones, but they also have a little less fiber. A medium-sized fruit, weighing about 400 g, contains approximately 130 kcal. The low figure is explained by the high water content - about 90%.

Glycemic index

The glycemic index (GI) of grapefruit is 25 units. This is the lowest indicator among citrus fruits, so nutritionists recommend consuming this fruit for diabetics and those who want to lose weight.

The glycemic index is an indicator that characterizes how quickly glucose enters the blood. Eating foods with a high GI causes glucose levels to rise sharply. This may lead to undesirable consequences.

Low glucose levels do not have the best effect on a person's condition. Such people experience low performance and loss of strength, and the activity of brain cells deteriorates. If glucose levels exceed normal levels, the body begins to store the excess in fat stores, which leads to weight gain.

Pros of low GI foods, which include grapefruit:

• gradually saturates the body, which allows you not to feel hungry for a long time;
• no sudden spikes in blood sugar levels;
• slow consumption of nutrients for the needs of the body, which does not allow them to enter fat tissue and increase it.

But such products also have disadvantages. The main one is that replenishment of glycogen reserves takes a long time. This affects the body’s receipt of energy reserves - the process occurs too slowly. To replenish your body with the required amount of energy, you need to eat a lot of low GI foods. This is almost impossible to achieve.

Harm and contraindications

Citrus should be consumed with caution if you have the following health problems:

• increased acidity;
• peptic ulcer;
• hepatitis;
• gastritis;
• cholecystitis;
• nephritis;
• enteritis.

Individual intolerance to this fruit is also important. If after consuming it you experience rashes on the body or itching, then it is advisable to completely exclude citrus from the diet and consult your doctor for advice.

The fruit has the ability to interact with certain medications due to the content of a substance such as furanocoumarin. It completely neutralizes the effect of some drugs, while enhancing or slightly reducing others. For example, grapefruit neutralizes many oral contraceptives.

Despite the fact that the fruit helps fight bleeding gums, it harms tooth enamel. It is recommended to rinse your mouth after eating the fruit and drink the juice through a straw.

Since citrus fruits are strong allergens, they should not be overused. You can eat no more than 2 grapefruits per day.

Grapefruit Insulin Index

The insulin index (AI) is an indicator that characterizes how quickly the pancreas produces insulin after consuming any product. The standard equal to 100 units is considered to be a piece of white bread with a calorie content of 240 kcal. The lower the AI ​​value, the less insulin is produced. Grapefruit's AI is 22.

Insulin is a hormone that maintains blood sugar levels. The more it is, the more difficult it is for the body to burn fat. The insulin index shows how much consumption of a product increases hormone synthesis within 2 hours after a meal.

How to use

For weight loss, it is used not only as a whole fruit, but also in the form of juice, salad additives, and essential oil.

Fresh grapefruit

There are specially designed diets, but proper inclusion of fruit in the daily diet is also useful. There are several ways to use it for weight loss:

• Used as a component of salads.
• The grapefruit diet lasts from 3 to 14 days. The diet is based on replacing your usual food for breakfast or dinner with grapefruit, and the rest will be light and low-fat food. This is either boiled fish or chicken, or a vegetable salad seasoned with olive oil or lemon juice.

When using the grapefruit diet, it is recommended to consult a nutritionist or doctor, since the presence of one contraindication leads to unpleasant consequences. If you are going to go on this diet for the first time, then choose the right option - proven and with a minimum number of days.

Essential oil

Grapefruit oil for weight loss is used externally or internally. In the latter case, the bottle or instructions indicate that the oil can be eaten. Then drop 4-5 drops onto a slice of bread and eat it to suppress hunger. Used as an additive to vegetable oils. Grapefruit essential oil can be used externally for weight loss in various ways.

1. Wrap. It is required not as a separate component, but as an additive to the main thing. The wrap is based on clay, seaweed or honey, to which 5-10 drops of grapefruit oil are added.
2. Massage. Mixes with olive or vegetable oil. It is recommended to apply after showering or bathing to problem areas.
3. Fragrant baths. Add 8-10 drops. First you need to dissolve grapefruit oil in milk.
