Its in the food. I give you a good example of modern food. Mcdonalds Hamburger.
Bread-> genetically modified corn, grown with pestizides, mixed with great amount of white drug(sugar) to bump insulin production so person eats MOAR.
Meat -> genetically selected animals, grown in closed factories, in cages, rarely more than 4 months old, pumped with grown hormones and antibiotics to prevent epidemies(cause no animal can live in such conditions; both hormones and antibiotics stay within meat and are transfered into eaters blood system). The meat is grilled in palm oil(cheapest) which contains GREAT amount of saturated fatty acids and nothing else - palm oil literally trashes blood vessels and organs. And because its grilled welcome acrolein and other cancerogene or toxic substances, free radicals included.
Sauce -> genetically modified tomatos(in best cases) with pesticides, picked up in early stages from fields and transfered over 4 months to production plants over the sea, then made to ripe via gas, mixed with good amount of white drug(sugar) or its replacement(all - cancerogenes), emulsifiers(variety, to boost endproduct amount and minimize cost), good deal of glutamate.
Best served cold.
