“Human Nutrition: Food Spectrum” is an overview of healthy eating based on USDA guidance and modern nutrition science. The video explains major food groups—grains, fruits and vegetables, protein sources, dairy, oils, sugar, salt, and alcohol—and highlights key concepts such as whole grains vs. refined grains, fiber, calories, amino acids, saturated and unsaturated fats, calcium, sodium, and added sugar. It emphasizes nutrient-dense food choices, reading nutrition labels, portion awareness, and the benefits of fruits, vegetables, legumes, fish, and low-fat dairy or calcium-rich alternatives. The program also compares the history of the food pyramid, MyPyramid, and MyPlate, showing how dietary guidelines support balanced meals and informed food choices. This content aligns well with health, life science, and consumer education curricula. Part of the "Human Nutrition" series.
