"Human Nutrition: Where Does Your Food Come From?" explores how food moves from agriculture to the modern food industry, explaining mass production, preservatives, packaging, shelf life, and food processing. Using milk as a case study, the video traces farm-to-store steps such as pasteurization, homogenization, quality testing, and packaging. It also defines USDA organic food, compares organic and conventional farming, and examines sustainability, pesticides, hormones, antibiotics, and consumer labeling. The video further compares fresh, local, frozen, and canned foods, highlighting nutritional quality, sodium, ripeness, storage, and access. With strong connections to nutrition, agriculture, consumer education, and environmental science, this resource supports curriculum topics on food systems, health, and informed decision-making. Part of the "Human Nutrition" series.
