The heat is unbearable, many people have poor appetite, and cold drinks and food are highly sought after

Frozen sweets can't hydrate and prevent heatstroke

Frozen sweets like ice cream, ice cream, and smoothies won't help you fight the heat

To prevent heatstroke, you need to increase the supply of potassium, sodium and B vitamins, as well as antioxidants

Frozen sweets are tempting because they have a lot of added sugar, which produces a pleasant sweetness, but added sugar is not a heatstroke ingredient

The World Health Organization and China's dietary guidelines recommend that the amount of added sugar be controlled within 50 grams per day, preferably within 25 grams, and summer is no exception

Cold drinks don't help cool down

Some people may say: After all, the temperature of frozen food is low.

Because they take away too little heat

Eating cold food will not help you lose weight

Some people also ask: Drinking iced drinks can't cool down the body, so can it consume body calories and help lose weight? The answer is still no

Please note that food energy is calculated in kcal, 1 gram of fat = 9 kcal of energy, 1 gram of sugar = 4 kcal of energy

According to China's nutrient supply standards, the daily calorie intake of light-weight adults is 1800 kcal for women and 2250 kcal for men

Cold drinks and cold foods lead to health risks

In fact, there are certain health risks associated with drinking a lot of cold drinks and eating cold food quickly

　　According to reports, a 19-year-old boy drank a lot of ice water after sweating while playing football, which resulted in myocardial infarction; an adult male induced myocardial infarction after eating iced food

　　Exercising in summer will increase the burden on the cardiovascular system.

　　In short, under the heat of the summer, eating cold food will not relieve the heat, and eating warm food is safer
