Nutrition and health: Expert advice on vitamin D and skin aging

Medical experts provide guidance on how nutrition and timing affect vitamin levels and skin health. Endocrinologist Stephan Scharla notes that the timing of vitamin D intake can influence its absorption and utilization in the body. While the body synthesizes much of its vitamin D through UVB rays, deficiency is common in Central and Northern Europe during winter months when UVB radiation is insufficient.

Regarding skin aging, nutritional physician Dr. Matthias Riedl explains that certain dietary habits can accelerate wrinkle formation. He identifies nicotine and excessive alcohol consumption as significant factors that damage skin elasticity and promote inflammation. Additionally, foods that cause rapid blood sugar spikes, such as toast and jam, may negatively impact skin health and contribute to premature aging.
