Organic foods: Are they safer? More nutritious?
Organic foods: Are they safer? More nutritious?
Understand the differences between organic foods and traditionally grown foods when it comes to nutrition, safety and price.
Once found only in health food stores, organic food is now a regular feature at most supermarkets. And that''s created a bit of a dilemma in the produce aisle.
On one hand, you have a conventionally grown apple. On the other, you have one that''s organic. Both apples are firm, shiny and red. Both provide vitamins and fiber, and both are free of fat, sodium and cholesterol. Which should you choose? Get the facts before you shop.
Conventional vs. organic farming
The word "organic" refers to the way farmers grow and process agricultural products, such as fruits, vegetables, grains, dairy products and meat. Organic farming practices are designed to encourage soil and water conservation and reduce pollution.
Farmers who grow organic produce don''t use conventional methods to fertilize and control weeds. Examples of organic farming practices include using natural fertilizers to feed soil and plants, and using crop rotation or mulch to manage weeds.
Organic or not? Check the label
The U.S. Department of Agriculture (USDA) has established an organic certification program that requires all organic foods to meet strict government standards. These standards regulate how such foods are grown, handled and processed.
Any product labeled as organic must be USDA certified. Only producers who sell less than $5,000 a year in organic foods are exempt from this certification; however, they''re still required to follow the USDA''s standards for organic foods.
If a food bears a USDA Organic label, it means it''s produced and processed according to the USDA standards. The seal is voluntary, but many organic producers use it.
Products that are completely organic — such as fruits, vegetables, eggs or other single-ingredient foods — are labeled 100 percent organic and can carry the USDA seal.
Foods that have more than one ingredient, such as breakfast cereal, can use the USDA organic seal plus the following wording, depending on the number of organic ingredients:
- 100 percent organic. To use this phrase, products must be either completely organic or made of all organic ingredients.
- Organic. Products must be at least 95 percent organic to use this term.
Products that contain at least 70 percent organic ingredients may say "made with organic ingredients" on the label, but may not use the seal. Foods containing less than 70 percent organic ingredients can''t use the seal or the word "organic" on their product labels. They can include the organic items in their ingredient list, however.
Do ''organic'' and ''natural'' mean the same thing?
No, "natural" and "organic" are not interchangeable terms. You may see "natural" and other terms such as "all natural," "free-range" or "hormone-free" on food labels. These descriptions must be truthful, but don''t confuse them with the term "organic." Only foods that are grown and processed according to USDA organic standards can be labeled organic.
Organic food: Is it more nutritious?
Probably not, but the answer isn''t yet clear. A recent study examined the past 50 years'' worth of scientific articles about the nutrient content of organic and conventional foods. The researchers concluded that organically and conventionally produced foodstuffs are not significantly different in their nutrient content.
Organic food: Other considerations
Many factors influence the decision to choose organic food. Some people choose organic food because they prefer the taste. Yet others opt for organic because of concerns such as:
- Pesticides. Conventional growers use synthetic pesticides to protect their crops from molds, insects and diseases. When farmers spray pesticides, this can leave residue on produce. Organic farmers use insect traps, careful crop selection (disease-resistant varieties), predator insects or beneficial microorganisms instead to control crop-damaging pests. Some people buy organic food to limit their exposure to these residues. Organic produce typically carries significantly fewer pesticide residues than does conventional produce. However, residues on most products — both organic and nonorganic — don''t exceed government safety thresholds.
- Food additives. Organic regulations ban or severely restrict the use of food additives, processing aids (substances used during processing, but not added directly to food) and fortifying agents commonly used in nonorganic foods, including preservatives, artificial sweeteners, colorings and flavorings, and monosodium glutamate.
- Environment. Some people buy organic food for environmental reasons. Organic farming practices are designed to benefit the environment by reducing pollution and conserving water and soil quality.
Are there downsides to buying organic?
One common concern with organic food is cost. Organic foods typically cost more than do their conventional counterparts. Higher prices are due, in part, to more-expensive farming practices.
Because organic fruits and vegetables aren''t treated with waxes or preservatives, they may spoil faster. Also, some organic produce may look less than perfect — odd shapes, varying colors or smaller sizes. However, organic foods must meet the same quality and safety standards as those of conventional foods.
Food safety tips
Whether you go totally organic or opt to mix conventional and organic foods, be sure to keep these tips in mind:
- Select a variety of foods from a variety of sources. This will give you a better mix of nutrients and reduce your likelihood of exposure to a single pesticide.
- Buy fruits and vegetables in season when possible. To get the freshest produce, ask your grocer what day new produce arrives. Or buy food from your local farmers market.
- Read food labels carefully. Just because a product says it''s organic or contains organic ingredients doesn''t necessarily mean it''s a healthier alternative. Some organic products may still be high in sugar, salt, fat or calories.
- Wash and scrub fresh fruits and vegetables thoroughly under running water. Washing helps remove dirt, bacteria and traces of chemicals from the surface of fruits and vegetables. Not all pesticide residues can be removed by washing, though. You can also peel fruits and vegetables, but peeling can mean losing some fiber and nutrients.
