Healthy Food Groups - JSON

Healthy food groups are classifications of nutritionally valuable food categories that are effective in preventing chronic diseases, including vegetables, fruits, whole grains, legumes, fish, and poultry. These food groups are recommended by authoritative global institutions such as WHO dietary guidelines, the Dietary Guidelines for Americans (2025-2030), and Japan's Dietary Reference Intakes. Scientific evidence supports their health benefits including anti-inflammatory effects, antioxidant properties, and cardiovascular protection, making them the foundation of a balanced diet.
