Introduction: during the hot summer, there is always a large number of heat accumulating in the human body and can not be expelled out, and this may easily lead to diseases. As a result, we should pay great attention to the diet in summer. Generally speaking, we should better eat less of the following three kinds of food in summer.

First, eat less warm-natured or hot-natured fruits.
If you eat a lot of warm-natured or hot-natured fruits such as litchi and longan, it will easily bring too much heat to the body, thus leading to diseases. During the hot summer, people tend to suffer from insomnia, and the metabolic rate is on a high level. As a result, it is very harmful to eat warm-natured or hot-natured fruits. What's more, those who had a fever or inflammation should especially keep away from these fruits. In addition to litchi and longan, there are also many other kinds of warm-natured or hot-natured fruits, such as peach, guava, cherry, coconut, durian, apricot, and so on.

Second, eat less nuts.
Nuts refer to the seeds which contain a large number of oil and fat, such as peanut, walnut, cashew nut, pine nut, melon seeds, almond, pistachio nut, and so on. Nuts are very nutritious and beneficial to human health. However, during the summer, you should not eat too much of this kind of food. This is because nuts contain a high content of calories, and they will produce a lot of heat in the body. The calorie of 50 grams of melon seeds is equivalent to that of a large bowl of rice. To average people, eating about 30 grams of nuts every day is an appropriate amount.

Three, eat less meat.
When the temperature exceeds 35 degree celsius, people will sweat a lot, and this may increase the viscosity of blood, and make people irritable. If you eat a lot meat at this moment, it will make the temper much worse. Meat contains a lot of animal protein, which can reduce the content of tryptophan in the brain, and make people aggressive and anxious. Secondly, meat contains little calcium, so if you eat too much, it may decrease the concentration of calcium in the body, and this can also aggravate the irritable temper. What's more, eating too much meat can cause vascular sclerosis, and then increase the level of blood pressure, while high blood pressure is an important for emotional instability.
