Organic food

A research shown that organic food are more health than the non-organic varieties which mean organic food are more healthy for the people. Organic product possessed antioxidant which is a molecule capable of inhibiting the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons from a substance to an oxdizing agent. Oxidation reactions can produce free radicals. In turn, these radicals can start chain reactions that damage cells. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions. They do this by being oxidized themselves, so antioxidants are often reducing agents such as thiols,ascorbic acid or polyphenols. Although oxidation reactions is crucial for life, they also can be damaging, thus antioxidant will help us.
Organic food has it bad point too.
organic food has more insect damage because growers can't use insecticides. And organic produce is usually smaller because growers can't use fertilizers, or herbicides, which would reduce competition from weeds. And it is less nutritious because the competing weeds "steal" some of the nutrients the plants need. And organic food is usually more costly, because 1, growing foods without all the conventional methods is more costly, and 2, yields are usually less, so cost has to be spread out over smaller quantities.

Although organic food are way healthier, not all of the people consume organic food or not the reason why people consume organic food.
