Document Summary
Where you live, who you live with, how you live- has a lot to do with what you choose to eat. Environmental factors that influence our food choices include economics, lifestyle, culture, and religion. Where you live- location and climate affect food costs, a major determinant of food choice. Wealthier households spend 7% of their after tax income on food, low-income families spend around 25% of their income on food. It is assumed that wealthier households have more nutritious diets b/c they can afford to buy higher-quality lean meats, more fish& seafood, and more fruits and veggies; nearly 20% of low income households bought no fruits or vegetables. Our fast-paced society has little time/ patience for food preparation. Current trends suggest we eat at home more often, but we are constantly eating ready-to-eat or heat-and- eat food. 4 classic tastes-sweet, sour, salty, and bitter, one additional taste sensation is umami.
