Body Weight and Nutrition Needs: Overweight people may need more vitamin C than current health standards. Let's explain how it's beneficial for your weight.

Do overweight people need more vitamin C?
Do Overweight People Need More Vitamin C? Vitamin C has long been considered an essential nutrient for our bodies. People commonly associate it with preventing colds and boosting immunity. But new research suggests that vitamin C may be even more important, especially for overweight individuals. Let's explore the findings.
What did the research reveal?
Researchers at the University of Otago in New Zealand, in a study published in the journal Critical Reviews in Food Science and Nutrition, found that overweight people may need more vitamin C than current health standards. This finding is significant because obesity is rapidly increasing worldwide, and many people may be unknowingly deficient in this essential nutrient. Vitamin C plays many important roles in the body. It repairs tissue, strengthens the immune system, and acts as an antioxidant, protecting the body from damage caused by free radicals. It is also essential for skin, wound healing, and mental health.
Advice on the right dosage
Health guidelines generally recommend a set amount for everyone. For example, in New Zealand, the recommended daily intake of vitamin C is 45 mg, based on a healthy adult weighing approximately 70 kg. However, lead researcher Anitra Carr says this one-size-fits-all approach may not be appropriate. As body weight increases, vitamin C needs may also increase.
What did the research reveal?
Research has found that for every 10 kilograms of body weight, the body may need approximately 17 to 22 milligrams of additional vitamin C. This means that overweight individuals should consume more of this nutrient than they need. To reach this conclusion, scientists analyzed data from two large studies involving thousands of participants.
The results showed that while most people appeared to have adequate vitamin C based on current recommendations, when weight was taken into account, only one-third to one-half of people had adequate levels. Experts believe that obesity can lead to mild inflammation, which can lead to faster vitamin C depletion. This is why overweight individuals may develop a deficiency more quickly.
How can we fulfill it in the body?
The good news is that vitamin C is easy to supplement. Fruits and vegetables like oranges, kiwis, strawberries, and bell peppers are good sources. Small changes, like eating an extra serving of fruit each day, can help address this deficiency.
