Is it worth buying organic

Which Food to Buy Organic (and How to Spend Less When You Do)

Is Organic Healthier?That depends. In general, the protein, fat, and carbohydrates are the same as those in conventional foods, MacLean says. The vitamin and mineral content changes are pretty negligible as well. A 2014 analysis of 343 studies, published in the British Journal of Nutrition, found that organic produce contained higher levels of disease-fighting antioxidants than conventional produce did. Other studies have found no significant differences.

Bringing produce, whether conventional or organic, from a distance can have a negative impact on nutrients, says Mary Ellen Camire, PhD, a professor of food science and human nutrition at the University of Maine in Orono. And the U.S. imports organic food from many countriesalmost 100 in 2021, according to Reana Kovalcik, director of public affairs at the Organic Trade Association.

Does It Have Fewer Pesticides?Yes. A small study published in Environmental Research in 2019 revealed that people who switched from a conventional diet to an organic one had lower levels of pesticide metabolites in their urine. And while what we know about the harm of synthetic pesticides is limited, the Environmental Protection Agency says agricultural pesticide exposure has been associated with asthma, bronchitis, non-Hodgkins lymphoma, Parkinsons disease, and certain cancers. In addition, a study published in JAMA Internal Medicine in 2020 reported a higher risk of dying from any cause as well as from cardiovascular disease in people with the highest levels of pyrethroid pesticide metabolites in their urine. Some research also suggests that children with greater exposure to certain pesticides are more likely to be diagnosed with attention deficit hyperactivity disorder and that synthetic pesticides may disrupt our endocrine systems, which are responsible for hormone regulation.

Is Organic Better for the Environment?Yes. Synthetic pesticides and fertilizers can damage soil and pollute water. Many of the pesticides and synthetic forms of fertilizer, if not managed and fine-tuned, often end up in our water and even in our fish, says Garry Stephenson, PhD, a professor in the department of crop and soil science at Oregon State University in Corvallis. Nitrogen-based fertilizer, often used in conventional agriculture, is a major contributor to air and water pollution, according to the Natural Resources Defense Council.

These days, however, some conventional farmers are turning to methods that spare the environment. For instance, some are switching to organic-friendly fertilizer, says Matt Ryan, PhD, an associate professor in the School of Integrative Plant Science at Cornell University in Ithaca, N.Y.

When it comes to farm animals, organic rules call for them to have year-round outdoor access and to be raised on organic land, and for grazing animals like cattle to have access to organic pastures at least 120 days a year. Space to exercise is required, but animals dont have to get a certain amount of space or never be caged, and overall, animal welfare requirements for USDA Organic certification are minimal.

Do the Animals Receive Any Antibiotics?Generally, no, with the exception of chickens and turkeys still in the egg and on their first day of life. But routine antibiotics are still widely used in conventional beef and poultry, which can lead to antibiotic-resistant infections. That means infections [in animals and people] that used to be easily cured may have the potential to become serious, even life-threatening, says James E. Rogers, PhD, director of food safety research and testing at CR.

Nutrition and healthy eating

Organic foods: Are they safer? More nutritious?

Discover the difference between organic foods and their traditionally grown counterparts when it comes to nutrition, safety and price.

By Mayo Clinic Staff

Once found only in health food stores, organic food is now a common feature at most grocery stores. And that's made a bit of a problem in the produce aisle.

For example, you can pick an apple grown with usual (conventional) methods. Or you can pick one that's organic. Both apples are firm, shiny and red. They both provide vitamins and fiber. And neither apple has fat, salt or cholesterol. Which should you choose? Get the facts before you shop.

What is organic farming?

The word "organic" means the way farmers grow and process farming (agricultural) products. These products include fruits, vegetables, grains, dairy products such as milk and cheese, and meat. Organic farming practices are designed to meet the following goals:

• Improve soil and water quality
• Cut pollution
• Provide safe, healthy places for farm animals (livestock) to live
• Enable natural farm animals' behavior
• Promote a self-sustaining cycle of resources on a farm

Materials or methods not allowed in organic farming include:

• Artificial (synthetic) fertilizers to add nutrients to the soil
• Sewage sludge as fertilizer
• Most synthetic pesticides for pest control
• Using radiation (irradiation) to preserve food or to get rid of disease or pests
• Using genetic technology to change the genetic makeup (genetic engineering) of crops, which can improve disease or pest resistance, or to improve crop harvests
• Antibiotics or growth hormones for farm animals (livestock)

Organic crop farming materials or practices may include:

• Plant waste left on fields (green manure), farm animals' manure or compost to improve soil quality
• Plant rotation to keep soil quality and to stop cycles of pests or disease
• Cover crops that prevent wearing away of soil (erosion) when sections of land aren't in use and to plow into soil for improving soil quality
• Mulch to control weeds
• Insects or insect traps to control pests
• Certain natural pesticides and a few synthetic pesticides approved for organic farming, used rarely and only as a last choice and coordinated with a USDA organic certifying agent

Organic farming practices for farm animals (livestock) include:

• Healthy living conditions and access to the outdoors
• Pasture feeding for at least 30% of farm animals' nutritional needs during grazing season
• Organic food for animals
• Shots to protect against disease (vaccinations)

Organic or not? Check the label

The U.S. Department of Agriculture (USDA) has set up an organic certification program that requires all organic food to meet strict government standards. These standards control how such food is grown, handled and processed.

Any product labeled as organic on the product description or packaging must be USDA certified. If it's certified, the producer may also use an official USDA Organic seal.

The USDA says producers who sell less than $5,000 a year in organic food don't need to be certified. These producers must follow the guidelines for organic food production. But they don't need to go through the certification process. They can label their products as organic. But they can't use the official USDA Organic seal.

Products certified 95 percent or more organic may display this USDA seal.

The USDA guidelines describe organic foods on product labels as:

• 100% organic. This label is used on certified organic fruits, vegetables, eggs, meat or other foods that have one ingredient. It may also be used on food items with many ingredients if all the items are certified organic, except for salt and water. These may have a USDA seal.
• Organic. If a food with many ingredients is labeled organic, at least 95% of the ingredients are certified organic, except for salt and water. The items that aren't organic must be from a USDA list of approved additional ingredients. These also may have a USDA seal.
• Made with organic. If a product with many ingredients has at least 70% certified organic ingredients, it may have a "made with organic" ingredients label. For example, a breakfast cereal might be labeled "made with organic oats." The ingredient list must show what items are organic. These products can't carry a USDA seal.
• Organic ingredients. If a product has some organic ingredients but less than 70% of the ingredients are certified organic , the product can't be labeled as organic. It also can't carry a USDA seal. The ingredient list can show which ingredients are organic.

Does 'organic' mean the same thing as 'natural'?

No, "natural" and "organic" are different. Usually, "natural" on a food label means that the product has no artificial colors, flavors or preservatives. "Natural" on a label doesn't have to do with the methods or materials used to grow the food ingredients.

Also be careful not to mix up other common food labels with organic labels. For example, certified organic beef guidelines include pasture access during at least 120 days of grazing season and no growth hormones. But the labels "free-range" or "hormone-free" don't mean a farmer followed all guidelines for organic certification.

Organic food: Is it safer or more nutritious?

Some data shows possible health benefits of organic foods when compared with foods grown using the usual (conventional) process. These studies have shown differences in the food. But there is limited information to prove how these differences can give potential overall health benefits.

Potential benefits include the following:

• Nutrients. Studies have shown small to moderate increases in some nutrients in organic produce. Organic produce may have more of certain antioxidants and types of flavonoids, which have antioxidant properties.
• Omega-3 fatty acids. The feeding requirements for organic farm animals (livestock) usually cause higher levels of omega-3 fatty acids. These include feeding cattle grass and alfalfa. Omega-3 fatty acids a kind of fat are more heart healthy than other fats. These higher omega-3 fatty acids are found in organic meats, dairy and eggs.
• Toxic metal. Cadmium is a toxic chemical naturally found in soils and absorbed by plants. Studies have shown much lower cadmium levels in organic grains, but not fruits and vegetables, when compared with crops grown using usual (conventional) methods. The lower cadmium levels in organic grains may be related to the ban on synthetic fertilizers in organic farming.
• Pesticide residue. Compared with produce grown using usual (conventional) methods, organically grown produce has lower levels of pesticide residue. The safety rules for the highest levels of residue allowed on conventional produce have changed. In many cases, the levels have been lowered. Organic produce may have residue because of pesticides approved for organic farming or because of airborne pesticides from conventional farms.
• Bacteria. Meats produced using usual (conventional) methods may have higher amounts of dangerous types of bacteria that may not be able to be treated with antibiotics. The overall risk of contamination of organic foods with bacteria is the same as conventional foods.

Are there downsides to buying organic?

One common concern with organic food is cost. Organic foods often cost more than similar foods grown using usual (conventional) methods. Higher prices are due, in part, to more costly ways of farming.

Food safety tips

Whether you go totally organic or choose to mix conventional and organic foods, keep these tips in mind:

• Choose a variety of foods from a mix of sources. You'll get a better variety of nutrients and lower your chance of exposure to a single pesticide.
• Buy fruits and vegetables in season when you can. To get the freshest produce, ask your grocer what is in season. Or buy food from your local farmers market.
• Read food labels carefully. Just because a product says it's organic or has organic ingredients doesn't mean it's a healthier choice. Some organic products may still be high in sugar, salt, fat or calories.
• Wash and scrub fresh fruits and vegetables well under running water. Washing helps remove dirt, germs and chemical traces from fruit and vegetable surfaces. But you can't remove all pesticide traces by washing. Throwing away the outer leaves of leafy vegetables can lessen contaminants. Peeling fruits and vegetables can remove contaminants but may also cut nutrients.
