Vitamins, as the name suggests, are essential elements for sustaining life. They are generally obtained through diet, but poor eating habits can lead to their loss. Let's take a look at which habits can cause vitamin loss.
1. Alcohol "eats up" Vitamin B
For alcohol to be metabolized normally in the body, a sufficient amount of Vitamin B is required. Therefore, long-term and heavy drinking can lead to a deficiency of Vitamin B in the body. Drinking more than one cocktail a day comes at the cost of accelerating the consumption of Vitamin B. Those who have too many daily social engagements and drink excessively should pay attention to supplementing B vitamins.
2. Computers "steal" Vitamin A
Staring at a computer screen for more than 3 consecutive hours can cause a lack of Vitamin A in the optic nerve cells, as it is directly related to the light-sensitive function of the retina. Therefore, computer users should eat more foods rich in Vitamin A, such as carrots, pumpkins, and various dairy products.
3. High and low temperatures "consume" multiple vitamins
Vitamins are involved in the body's temperature regulation, so their consumption increases in high or low-temperature environments. Therefore, people with weaker temperature regulation mechanisms should pay more attention to appropriately supplementing multiple vitamins when the temperature changes significantly. In addition, the body sweats profusely in high temperatures, which accelerates the excretion of multiple vitamins with sweat.

4. Intense exercise "depletes" multiple vitamins
During high-intensity exercise, the body needs more energy, and the metabolic rate of cells increases, thereby accelerating the consumption of vitamins in the body. Therefore, people who frequently engage in high-intensity exercise, such as athletes, should consume more foods rich in various vitamins or appropriately supplement with multivitamin tablets.
5. Cigarettes "suck away" Vitamin C
Harmful components in cigarette smoke, such as tar, can deplete Vitamin C in large quantities. The loss of Vitamin C is even greater for passive smokers. Therefore, people who smoke or are exposed to secondhand smoke should eat more foods rich in Vitamin C, such as tomatoes.
6. Improper cooking methods waste vitamins
When carrots are eaten raw, cooked with a trace amount of oil, and cooked with a sufficient amount of oil, the digestibility and absorption rate of carotene are 10%, 30%, and 90%, respectively. This shows that eating carrots after cooking with oil has higher nutritional value than eating them raw.
Vitamin C is water-soluble and can be easily lost when washing vegetables. Furthermore, high temperatures or prolonged heating during cooking, such as in stewing or casseroles, can destroy a large amount of Vitamin C in vegetables. Vitamin C is also easily oxidized by oxygen in the air; the longer vegetables and fruits are stored, the greater the loss of Vitamin C.
