Organic foods provide a variety of benefits. Some studies show that organic foods have more beneficial nutrients, such as antioxidants, than their conventionally grown counterparts. In addition, people with allergies to foods, chemicals, or preservatives often find their symptoms lessen or go away when they eat only organic foods. In addition:
Organic proce contains fewer pesticides. Pesticides are chemicals such as fungicides, herbicides, and insecticides. These chemicals are widely used in conventional agriculture and resies remain on (and in) the food we eat.
Organic food is often fresher. Fresh food tastes better. Organic food is usually fresher because it doesn’t contain preservatives that make it last longer. Organic proce is often (but not always, so watch where it is from) proced on smaller farms near where it is sold.
Organic farming is better for the environment. Organic farming practices rece pollution (air, water, soil), conserve water, rece soil erosion, increase soil fertility, and use less energy. Farming without pesticides is also better for nearby birds and small animals as well as people who live close to or work on farms.
Organically raised animals are NOT given antibiotics, growth hormones, or fed animal byprocts. The use of antibiotics in conventional meat proction helps create antibiotic-resistant strains of bacteria. This means that when someone gets sick from these strains they will be less responsive to antibiotic treatment. Not feeding animal byprocts to other animals reces the risk of mad cow disease (BSE). In addition, the animals are given more space to move around and access to the outdoors, both of which help to keep the animals healthy.
Organic meat and milk are richer in certain nutrients. Results of a 2016 European study show that levels of certain nutrients, including omega-3 fatty acids, were up to 50 percent higher in organic meat and milk than in conventionally raised versions. This may be because organic milk and beef come from cattle that graze on a natural diet of grass, while conventional meat and milk usually comes from animals fed with grain.
Organic food is GMO-free. Genetically Modified Organisms (GMOs) or genetically engineered (GE) foods are plants or animals whose DNA has been altered in ways that cannot occur in nature or in traditional crossbreeding, most commonly in order to be resistant to pesticides or proce an insecticide. In most countries, organic crops contain no GMOs and organic meat comes from animals raised on organic, GMO-free feed.
