"营养与食品卫生学" can be translated into English as "Nutrition and Food Hygiene" or, more formally and comprehensively, "Nutrition and Food Sanitation Science".
"Nutrition" refers to the study of nutrients and other substances in food, their interactions within and outside the human body, and their impact on health and disease.
"Food Hygiene" or "Food Sanitation" pertains to the conditions and measures necessary to ensure the safety of food, from production to consumption, to prevent foodborne illnesses.
The choice between "hygiene" and "sanitation" may depend on the specific context or the emphasis one wishes to place, with "sanitation" often carrying a slightly broader or more formal connotation in scientific contexts. However, both terms are widely understood and accepted in the field.
