In vegetarian diets, which food category can provide essential amino acids necessary for growth?

• A. Legumes
• B. Dairy products
• C. Meat substitutes
• D. Fruits

Answer: (A)

Growing children rely on dietary protein to supply the essential amino acids needed for tissue growth and repair. Most plant foods are incomplete proteins, but legumes stand out as a strong source of essential amino acids, particularly lysine, which is often limited in cereals. Eating legumes regularly helps meet these amino acid needs, and pairing legumes with grains creates a complete protein profile that supports growth. Dairy products can also provide high-quality protein, but in vegetarian diets that exclude dairy, legumes are a reliable cornerstone. Fruits don’t contribute meaningful protein or essential amino acids for growth, so they don’t meet this need. Therefore, legumes are the best category to help provide essential amino acids for growth in vegetarian diets.
