Coke is not recommended. First of all, many colas are cold drinks. If you drink frozen food during menstruation, it will lead to abnormal uterine contraction, dysmenorrhea and abnormal menstrual flow. Secondly, cola is a carbonated drink, which contains a lot of gas. After drinking, it will cause bloating or stimulate gastric acid secretion, cause stomach pain and discomfort, affect menstrual appetite, and is not conducive to nutrient absorption. Finally, cola contains a substance phosphoric acid, which affects the absorption of iron, thus affecting the production of blood. Women will lose some blood during menstruation, which is easy to cause anemia. If they drink a lot of cola during menstruation, it will further aggravate the symptoms of anemia. No matter during menstruation or at ordinary times, it is not recommended to drink carbonated drinks such as cola and sprite, and not to eat spicy, stimulating and cold food, which may easily cause adverse effects on the body.

Precautions for menstrual diet are:

1, eat more foods that promote blood circulation.

Eat more green onions, fungus, peanuts, walnuts, dates, longan, roses and so on during menstruation. If you accidentally eat cold food or can't help eating ice during menstruation, you can drink more brown sugar and cook ginger to balance blood circulation and promote blood flow.

2. Eat more foods rich in calcium.

Studies have found that women's intake of large amounts of calcium and vitamin D can help reduce the risk of PMS. Women should take1200mg of calcium and 700 international units of vitamin D every day. You should eat more low-fat milk, cheese, yogurt, fortified orange juice and soy milk, salmon and vitamin D fortified milk, and get more sunshine.

3. Don't miss breakfast

In order to avoid feeling particularly hungry, three meals a day should be on time, especially don't miss breakfast. If you feel depressed during premenstrual period, then missing any meal will inevitably lead to large fluctuations in blood sugar and aggravate premenstrual syndrome.

4. Eat more fiber and lean protein.

Eat more whole grains such as brown rice, oats and barley bread, and eat more lean protein and various fruits and vegetables. Fiber helps the body eliminate excess estrogen. Eating more vegetables, beans, whole wheat, buckwheat and barley (not only rich in fiber, but also rich in magnesium) can get more vitamin B 1 and B2, which is very important to prevent PMS.

5. Eat less sugar

Sweets can lead to estrogen and progesterone disorders, and then reduce the level of serotonin in the brain, leading to emotional instability, more anxiety, and induce PMS. Experts suggest eating less or no sweets, drinking more water and eating some fresh fruits.
