How many calories are there in a cup of tea? the benefits and effects of drinking tea and tea to lose weight and lose weight

Tea contains nothing, only a small amount, but not zero calories.

A cup of brewed black tea (200,250ml) has about 2 calories (according to the USDA Nutrition Database), which is nothing compared to the recommended daily intake of 2000 calories for adults.

Calories mainly come from trace amounts of carbohydrates in tea. The same is true of most herbal tea.

Sugar increases calories.

A typical teaspoon of refined (white sugar) contains about 4 grams of sugar and 15 calories. Typical sugar packets, such as tea or coffee in some restaurants, contain about 3 grams, or 11 calories.

These calories provide no other nutritional value: no vitamins, minerals or protein.

Milk increases calories and nutrition

Milk or cream can increase the calories in tea, but the total contribution is usually small compared to the dairy products that people eat in their food.

These calories come from sugar (such as lactose, which naturally occurs in dairy products) and fat in milk.

2 tablespoons of whole milk (much more than most people put in tea) has only 18 calories, of which 9 calories come from fat. Even if cream is added to the tea, it is unlikely to increase calories.

Unlike sugar, milk also adds significant nutritional value.

Milk contains protein, about 3.5 grams per 100 grams, and some vitamin A, which is also a good source of calcium.

In many countries, milk is also fortified with vitamin D. Vitamins An and D are fat-soluble vitamins, so they are not well absorbed from skim milk.

Tea without sugar or milk tastes better

If you want to make your tea sweeter, you may want to consider natural sweet tea. If you are only used to drinking black tea, you may want to try green, white or oolong tea, many of which are naturally sweeter, smoother and less bitter.

Asian cultures generally drink pure unsweetened tea, which may taste better in this form.

In addition, according to the Japanese black tea researcher Meng Inochi mentioned in the "Fine Black Tea Science", black tea has the effect of weight loss.

It is said that the catechin of black tea can break down neutral fat (triglyceride).

When the human body moves, it will decompose the liver glycogen stored in the liver and convert it into energy, producing instant explosive force, which is an indispensable substance to provide energy.

Catechins from black tea can reduce the concentration of neutral fat in the blood and increase the proportion of fatty acids as an energy source for exercise.

Before the energy efficiency caused by fatty acids becomes worse, liver glycogen will remain in the body, so the physical strength will not decline naturally, so it will be able to maintain a full state of vitality for a long time.

Based on the above mechanism, many people will use black tea as a sports drink to improve sports performance.

Not only that, even those who pursue the effect of weight loss, as long as the introduction of black tea before exercise, neutral fat can be converted into energy consumption, helping to achieve the effect of weight loss.

However, black tea itself does not contain calories, so when you engage in strenuous exercise, you might as well add a little sugar or fruit juice to provide carbon water. Only in this way can black tea be called a more competent sports drink.
