Most food will cause death if consumed in excess and not as a part of a balanced diet.
Toxic compounds are present in grains, legumes, fruits and vegetables.
When a variety of foods in moderate amounts are consumed as a part of a normal diet, these toxic compounds do not accumulate in the body and hence, cause no problems. Some toxic compounds, such as hemagglutins in kidney beans and soybeans, are inactivated by moist heat. These items should not be eaten without cooking. There is also much concern and discussion about chemical contamination of food by insecticides, rodenticides and herbicides. While there are some rare incidents of excessive amounts of these chemicals on or in food, more than adequate control measures are taken by both the government and industry to prevent this occurrence.
