Title: The Truth About Vitamin C and its Role in Preventing Illness
Many people have heard about the importance of vitamin C for the immune system and its supposed ability to prevent colds. However, the dietitian team at Siriraj Hospital Piyamaharajakarun has provided some clarity on the matter.
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that is crucial for the immune system and acts as an antioxidant. It also plays a role in increasing iron absorption and tissue growth. However, the body cannot produce its own vitamin C, so it must be obtained from food sources such as fruits and vegetables.
The recommended daily intake for Thai people varies by age and gender, with pregnant women and those who are not pregnant requiring different amounts.
Consuming very high amounts of vitamin C can lead to adverse reactions such as nausea, stomach cramps, and diarrhea. Therefore, the maximum recommended daily intake is 2,000 milligrams.
It is important to note that vitamin C is easily lost when exposed to heat, so cooking methods should be adjusted to minimize the loss of this essential nutrient.
In conclusion, dietitians emphasize the importance of a balanced diet that includes plenty of fruits and vegetables to ensure an adequate intake of vitamin C. However, they also stress the importance of other factors such as rest, exercise, and stress management in helping the body fight off illness effectively.
For individuals with diabetes mellitus or kidney disease, it is crucial to follow dietary recommendations from a healthcare professional.
Overall, while vitamin C is important for overall health and immune function, it is just one piece of the puzzle in maintaining a healthy lifestyle.]
