A vegetarian diet can affect athletic performance positively and negatively, depending on the quality and balance of nutrient intake. While such a diet is often high in fiber, vitamins, and minerals, athletes must ensure adequate consumption of key nutrients like protein, iron, and B12, which are primarily found in animal products. When planned well, vegetarian diets can enhance performance and recovery through nutrient-rich foods. However, insufficient nutrient intake may hinder physical performance, making proper dietary planning essential for athletes following a vegetarian diet.
