Prevention of Chronic Diseases

Vitamin C and E play crucial roles in preventing chronic diseases. High intakes of fruits and vegetables, rich in these vitamins, are linked with lower cancer risk. These antioxidants help neutralize harmful molecules called free radicals which can damage cells.

Although vitamin C supplementation has not shown a significant effect on cancer incidence or mortality, it still offers various health benefits. It supports the immune system, helps produce collagen for healthy skin, and may improve heart health.

Vitamin E also contributes to heart health by reducing oxidative stress on blood vessels.

Support for Immune Function

Vitamin C boosts the immune system by producing white blood cells. These cells help fight infections. It also strengthens skin barriers to block pathogens. Vitamin C acts as an antioxidant, protecting cells from damage.

Adequate vitamin E intake further supports immune function. This fat-soluble vitamin enhances T-cell activity and helps prevent oxidative stress on immune cells. Eating nuts, seeds, and leafy greens ensures you get enough of this vital nutrient daily.

Conclusion

Getting enough antioxidants is vital. Aim for the recommended daily intake of vitamins C and E. These vitamins help keep your immune system strong and may prevent chronic diseases.
