2. 8 cups of water every day is good for you?

It is wrong to drink more than 8 cups of water or more than 1 liter of water every day. Because the amount of water intake varies from person to person. It's really important to hydrate yourself while living a day. Water is contained in a small amount in the food we consume, not in water. And in order to prevent dehydration, our bodies signal that we should drink water beforehand. For example, long hours of outdoor activities with strong sunlight make you thirsty and dehydrated. And if your urine color is bright yellow or the weather is hot, it's better to pay more attention to your water intake. Of course, it is helpful to drink cool water frequently when exercising in hot weather, but it is better to drink sports drinks than water because it is necessary to replenish salt that has escaped from sweat when water intake begins to exceed 2L. To determine the amount of water intake that varies from person to person, multiply your weight by 30. For example, if you weigh 70kg and are a person, 70kg x 30 = 2,100, so 2.1L is the appropriate amount of water intake. In addition, you should not drink caffeine-containing drinks such as black tea and coffee instead of water for water intake.

4. Would it really hurt your eyes if you read a book in the dark?

Reading in the dark is only a temporary visual impairment caused by eye fatigue, and it is not a big problem. However, if you use electronic devices such as smartphones in the dark, you should be careful because permanent vision loss may occur due to electromagnetic waves. One of the stories I heard a lot when I was young is the saying, "If you read a book in the dark, your eyes get bad." Is this true? In fact, when reading a book, the brightness of the surrounding environment does not have a significant impact on vision. Of course, reading a book in a place where the brightness is not enough can increase the fatigue of your eyes and make it difficult. However, it is a temporary phenomenon caused by eye fatigue without permanently deteriorating vision. However, on the contrary, if you look closely and for a long time at electronic devices that generate light, such as smartphones, it can affect your eyesight. Some wavelengths in electronic devices damage retinal cells, causing vision loss, and in the dark, the pupil is enlarged, so these wavelengths and light can be absorbed more. Therefore, it is recommended to refrain from actions that cause eye fatigue as much as possible in dark places.

5. Will eating too much sweet food lead to diabetes?

Sweet food is not a shortcut to diabetes, but if you eat it for too long, you will be more likely to develop diabetes along with obesity. Often, people think that eating a lot of sweet food can lead to diabetes. Diabetes here is a disease that refers to when insulin is not secreted or when it does not function properly even if it is secreted. Also, diabetics should refrain from eating sweet foods because it is difficult to control blood sugar on their own. Then, do you get diabetes if you eat too much sweet food? First of all, sweet food is not a direct cause of diabetes. Once you eat foods that contain a lot of simple sugars, your blood sugar rises rapidly and a large amount of insulin is released. If insulin is secreted properly and insulin is functioning properly, there is no big problem. However, if it lasts for a long time, it will not only cause obesity but also cause insulin resistance, increasing the risk of diabetes. Therefore, it is important to eat an appropriate amount when eating sweet foods, and it is better to refrain from excessive sugar foods such as snacks, candies, and carbonated drinks in your diet.

6. Does soda really help with digestion?

Favorite cola and food fizzy drinks. The unique freshness and freshness of soda is a great advantage that this drink can be loved so far. In particular, the carbonation of carbonated drinks that you drink after eating also gives you the feeling of helping digestion. The feeling of being digested and refreshed after drinking soda is only a temporary phenomenon caused by simple carbonation. Rather, if this habit continues, it will cause digestive disorders and damage the stomach. In addition, people with gastrointestinal disorders should be more careful.

8. Milk is the best when you have heartburn?

This is because the unique nature and coldness of milk have the effect of soothing the spicy stomach. However, drinking milk when you have heartburn results in further irritating the stomach wall. Of course, the protein component in milk protects the stomach wall, and the weak alkaline component dilutes and neutralizes the stomach acid. But these results are temporary, rather stimulating the stomach wall by promoting more gastric acid secretion to break down the protein in milk.

Nowadays, people tend to equate weight with health. But even a little overweight can be healthy, according to a team at Columbia University in the U.S. There is also controversy among medical experts over the accuracy of BMI. BMI, which is the value of weight (kg) divided by the square of height (㎡), is classified as underweight if it is less than 18.5, normal weight if it is 18.5 to 23, overweight if it is over 23 to 25, obese if it is over 25 to 30, and highly obese if it is over 30.

11. Gastrointestinal patients, should I only eat porridge?

When we have indigestion or gastrointestinal diseases, we only eat porridge.

It is also a healthy food for patients because it is relatively softer and easier to digest than regular foods that have died. But gastrointestinal patients don't have to eat porridge. In the case of major surgery such as gastric cancer surgery or intestinal bleeding, it is true that eating porridge is helpful, but other than that, there is no big difference between simple general food and porridge. This is because there is no big difference in digesting hard foods such as meat because if you chew it well, it eventually becomes like porridge.
