Document Summary
Exercise: suppose you are on a very limited budget. Please write down at least 3 factors. Quality the 3 most important factors for humans: We sense several tastes and textures through the mouth and numerous others through the nose. Sensed in the mouth: sweet, bitter, salty, sour, umami, fat, and hot (spicy) taste is an evolved adaptation that guides animal food choice. Salty: salt is an essential nutrient (rare for much of our evolutionary history) Umami: the taste of free glutamate, a common amino acid indicating the presence of protein. Glutamate rich foods: meat, fish, milk, some vegetables (e. g. tomatoes), some mushrooms and algae. Glutamate rich foods serve as natural taste enhancers (cheese, tomato sauce) Monosodium glutamate (msg) is an artificial taste enhancer. Msg can bring side effects such as headaches. Fat high energy content (more than twice (~9kcal) than carbohydrates and protein (~4 kcal)): nothing higher in energy content than fat itself.
