What happens to people if their food hygiene is poor?

poor food hygiene leads to malnutrition.... your body requires vitamins and protein to grow and maintain good health. people can develop many medical problems. your teeth suffer. your bones can get weak. with anemia - low iron- you are often tired, weak, easily bruised. low vitamin b-12 can cause nervous system problems.

if you eat too many fatty foods you can have problems with weight, clogged arteries, eventually heart disease.

if you eat foods (meat, eggs, vegtables) that aren't prepared or cooked properly you are subject to disease from bacteria-- saminella ... mad cow disease...
