It's a common misconception that vegans don't need to worry about protein intake. While younger vegans generally meet their protein needs, older individuals face a higher risk of deficiency, especially if legumes are lacking in their diet. As calorie requirements decrease with age, focusing on protein-rich foods becomes essential for maintaining immunity and muscle strength. Simple dietary adjustments, such as replacing grains with legumes and incorporating more vegetables, can help boost protein intake without increasing overall calories.
