Question

why do people consume junk food when they know it is unhealthly

Answer 1

junk food may actually be addictive. The body actually begins to crave salt, sugar and fat, according to some experts, which makes it hard to stop eating junk foods. Some critics claim that food scientists in junk food companies know this and specially formulate foods to get consumers hooked on them. Some industry experts compare the addictiveness of junk food to that of cigarettes and have called for major manufacturers of junk foods to make their options more healthy.
