Avoid these food combinations to maximize nutrient absorption

Coffee and tea with iron-rich foods hinder iron absorption. Leafy greens with cheese also reduce calcium uptake. Polyphenols in coffee and tea bind to iron, while oxalates in greens bind to calcium. Alcohol damages digestive cells, impairing vitamin absorption. Pairing vitamin C-rich foods with iron, or healthy fats with fat-soluble vitamins, can boost nutrient absorption.
