Nutritional research emphasizes the link between dietary choices and bodily functions such as immune support and collagen production. Early reports highlight that consuming various nuts can strengthen the immune system and improve heart health, while Vitamin C-rich foods like citrus fruits are essential for boosting collagen synthesis to maintain skin elasticity and joint health.

Subsequent guidance provides specific instructions on vitamin absorption. It notes that Vitamin D, which supports bone and brain health, is fat-soluble and should be consumed with healthy fats to maximize effectiveness. Vitamin C is identified as a critical water-soluble antioxidant necessary for wound healing and neutralizing free radicals, requiring consistent intake from sources like berries, peppers, and leafy greens.
