Understanding the Benefits of Organic Food and the Risks of GMOs and Pesticides

Organic food has become very popular. But navigating the maze of organic food labels, benefits, and claims can be confusing. Is organic food really healthier? Do GMOs and pesticides cause cancer and other diseases? What do all the labels mean? This guide can help you make better choices about which organic foods are healthier for you and better for the environment, and how you can afford to incorporate more organic food into your diet.

What is organic food?

Making a commitment to healthy eating is a great start towards a healthier life. Beyond eating more fruits, vegetables, whole grains, and good fats, however, there is the question of food safety, nutrition, and sustainability. How foods are grown or raised can impact both your health and the environment. This brings up the questions: What is the difference between organic foods and conventionally grown foods? Is “organic” always best? Are GMOs safe? What about locally grown foods?

What does “organic” mean?

The term “organic” refers to the way agricultural products are grown and processed. Specific requirements must be met and maintained in order for products to be labeled as "organic."

Organic crops must be grown in safe soil, have no modifications, and must remain separate from conventional products. Farmers are not allowed to use synthetic pesticides, bioengineered genes (GMOs), petroleum-based fertilizers, and sewage sludge-based fertilizers.

Organic livestock must have access to the outdoors and be given organic feed. They may not be given antibiotics, growth hormones, or any animal-by-products.

The benefits of organic food

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 produce contains fewer pesticides. Pesticides are chemicals such as fungicides, herbicides, and insecticides. These chemicals are widely used in conventional agriculture and residues 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 produce is often (but not always, so watch where it is from) produced on smaller farms near where it is sold.
• Organic farming is better for the environment. Organic farming practices reduce pollution (air, water, soil), conserve water, reduce 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 byproducts. The use of antibiotics in conventional meat production 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 byproducts to other animals reduces 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 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 produce an insecticide. In most countries, organic crops contain no GMOs and organic meat comes from animals raised on organic, GMO-free feed.

The controversy surrounding GMOs and pesticides

The ongoing debate about the effects of GMOs on health and the environment and whether GM food in the U.S. should be labeled is a controversial one. In most cases, GMOs are engineered to make food crops resistant to herbicides (weedkillers) and/or to produce an insecticide. For example, much of the sweet corn consumed in the U.S. is genetically engineered to be resistant to the herbicide Roundup and to produce its own insecticide, Bt Toxin.

As well as corn, GMOs are commonly found in U.S. crops such as soybeans, alfalfa, squash, zucchini, papaya, and canola, and are present in many breakfast cereals and much of the processed food that we eat. Take a look at your favorite canned or packaged food. If the ingredients include corn syrup or soy lecithin, chances are it contains GMOs.

Are GMOs safe?

While the U.S. Food and Drug Administration (FDA) and the biotech companies that engineer GMOs insist they are safe, many food safety advocates point out that these products have undergone only short-term testing to determine their effects on humans and the environment. Since the technology is relatively new, no long term studies have ever been conducted to confirm the safety of GMO use, while some animal studies have indicated that consuming GMOs may cause internal organ damage, slowed brain growth, and thickening of the digestive tract.

GMOs have been linked to increased food allergens and gastro-intestinal problems in humans. Many people think that altering the DNA of a plant or animal can also increase the chances of developing cancer. However, so far research into the link between GMOs and serious disease has proven inconclusive.

GMOs and the increased use of pesticides

The introduction of GMOs has had a profound effect on the level of pesticides present on and in our food, and potentially on the health of human beings and the environment. Since most GMOs are engineered for herbicide tolerance, the use of toxic herbicides like Roundup has increased 15 times since GMOs were introduced. Again, there is some controversy over the level of health risks posed by the use of pesticides.
