Organic foods have exploded in popularity over the last two decades.
In fact, US consumers spent $39.1 billion on organic produce in 2014 (1).
The popularity does not seem to be slowing down, as sales increased by more than 11% from 2014 to 2015 (1).
Many people think organic food is safer, healthier and tastier than regular food (2).
Others say it’s better for the environment and the well-being of animals.
This article objectively compares organic and non-organic foods, including their nutrient content and effects on human health.
What is Organic Food?
The term “organic” refers to the process of how certain foods are produced.
Organic foods have been grown or farmed without the use of artificial chemicals, hormones, antibiotics or genetically modified organisms.
In order to be labelled organic, a food product must be free of artificial food additives.
This includes artificial sweeteners, preservatives, coloring, flavoring andmonosodium glutamate (MSG).
Organically grown crops tend to use natural fertilizers like manure to improve plant growth. Animals raised organically are also not given antibiotics or hormones.
Organic farming tends to improve soil quality and the conservation of groundwater. It also reduces pollution and may be better for the environment.
The most commonly purchased organic foods are fruits, vegetables, grains, dairyproducts and meat. Nowadays there are also many processed organic products available, such as sodas, cookies and breakfast cereals.
Organic Foods May Contain More Nutrients
Studies comparing the nutrient content of organic and non-organic foods have provided mixed results.
This is most likely due to natural variation in food handling and production.
However, evidence does suggest that foods grown organically may be more nutritious.
Organically Grown Crops Have More Antioxidants and Vitamins
Several studies have found that organic foods generally contain higher levels ofantioxidants and certain micronutrients, such as vitamin C, zinc and iron (3, 4, 5, 6).
In fact, antioxidant levels can be up to 69% higher in these foods (6).
One study also found that organically grown berries and corn contained 58% more antioxidants and up to 52% higher amounts of vitamin C (5).
What’s more, one study reported that replacing regular fruit, vegetables and cereals with organic versions could provide extra antioxidants in the diet. This was comparable to eating 1-2 extra portions of fruit and vegetables daily (6).
Organic plants do not rely on chemical pesticide sprays to protect themselves. Instead, they produce more of their own protective compounds, namely antioxidants.
This may partly explain the higher levels of antioxidants in these plants.
Nitrate Levels are Generally Lower
Organically grown crops have also been shown to have lower levels of nitrate. In fact, studies have shown that nitrate levels are 30% lower in these crops (6, 7).
High nitrate levels are linked to an increased risk of certain types of cancer (8).
They’re also linked to a condition calledmethemoglobinemia, a disease in infants that affects the body’s ability to carry oxygen (8).
Organic Dairy and Meat May Have A More Favorable Fatty Acid Profile
