Is Organic Food Better For Your Health?

“Get the real deal on your meal” is the theme for Nutrition Month 2012.

I am going to be posting accurate information –all month long- about the foods you eat and bust up common food and nutrition myths.

The first myth that I would like to bust is the myth that “organic” food is healthier and safer than “non-organic”.

THE TRUTH

Both organic and non-organic foods are nutritious and safe to eat when you’re making healthy choices based on Canada’s Food Guide. Many factors affect a food’s nutritional value, such as where and how it was grown, stored, shipped and even how it was cooked.1,2 So organic foods may have more, about the same, or less nutrients than non-organic foods. And both organic and non-organic foods are grown and produced under strict regulations to make sure they are safe for you to eat.3 Like any food purchase, buying organic food is a personal choice.

Are organic foods better for my health?

Is organic food more nutritious?

Unfortunately, there is no simple answer to this question! It is hard to interpret research studies that compare organic food to food grown by conventional methods. Many factors such as the quality of soil, temperature and light during the growing season, and the variety of seeds planted, or the breed of animal can affect the nutritional content of a food. In most situations, these factors are not controlled so accurate comparisons can’t be made. Some research shows that vitamin A, beta-carotene, and the B vitamins are generally the same in vegetables and fruit, but some phytochemicals (compounds that are neither vitamins nor minerals, but thought to be helpful to health) are higher in organic produce. Therefore, some foods grown organically may have more nutritional value, and some may have the same, or even less, than those grown on non-organic farms. The best advice is to eat a variety of vegetables and fruit.

What is different about organic farming and how could that affect nutritional content?

For vegetables, fruit and cereal crops, organic farmers use techniques such as green manures and compost to enrich the soil. Green manures are special crops that are planted, grown, and then plowed back into the soil. Organic farmers also use both plant and animal compost to keep the soil fertile. These practices can result in higher nutrient content of the soil, and perhaps of foods grown in the soil. Some non-organic farmers may also use a combination of organic farming techniques such as green manures as well as non-organic farming techniques such as chemical fertilizers. This makes it hard to state that foods grown organically are more nutritious than foods grown in other ways.

Why are phytochemicals higher in organic foods?

Phytochemicals can affect the colour, taste and other properties of food, but one of the more important functions is to protect the plant from pests. Organic farmers often select seed varieties that are more naturally pest resistant, which means that the phytochemical levels may be higher than in other seed varieties.

How do I know if foods are organic?

For many years, the labelling of organic food was voluntary with a number of certification bodies taking responsibility for ensuring standards were met. In June 2009, new mandatory guidelines were implemented for organic food that is traded across provinces or countries. The Canadian Food Inspection Agency will work in cooperation with certification bodies to ensure that Canada-wide standards are met, and a special logo identifying the food as organic will be used on packaging. Visit http://www.inspection.gc.ca/english/fssa/orgbio/orgbioe.shtml for organic food labelling guidelines.

Is organic food as safe as other food?

The key to lowering food safety risks is to operate a well-managed farm, whether it is an organic farm or not. Organic farmers are good managers when they use properly composted animal manures and use preventive measures to protect crops from insects before damage occurs to the plants. Organically grown produce, such as salad greens, have been shown to be equivalent to conventional produce in terms of food safety. Organic foods should be prepared with the same precautions as conventional foods, i.e., vegetables and fruit should be washed prior to preparation and consumption. Rinsing also removes the minimal levels of pesticides typically found on produce. For more information on washing vegetables and fruit, visit www.hc-sc.gc.ca/fn-an/securit/kitchen-cuisine/safety-salubrite/handling-manipulation-eng.php

Sometimes though, extra precautions must be taken, for example, with organic chickens that are not routinely fed antibiotics to prevent bacterial contamination. Salmonella has been found to be higher in some organically grown chickens, but cooking chicken thoroughly and washing kitchen counters well will help prevent salmonella foodbourne illness.

Is there an advantage to buying organic food?

Like any purchase, buying organic food should be a personal choice, based on a food’s availability, price, appearance and taste, as well as the personal values of the buyer, such as preferring the way that organic foods are grown or raised. While some organic products may give consumers a small advantage, for example, in content of phytochemicals, what’s most important is that Canadians choose foods based on Eating Well with Canada’s Food Guide.
