Organic foods: Are they safer? More nutritious? - Mayo Clinic


Research organic food articles showing that organic farming, which uses fewer pesticides and synthetic fertilizers, can be better for the environment. At the supermarket, there are usually two sections in the produce aisle, organic food articles. The big price tag can lead people to assume organic food is better than conventionally grown food. But, in the United States, the label simply means that the food has met guidelines set out by the U.

Department of Agriculture. For instance, organic fruits, vegetables and other crops must not have been treated with synthetic fertilizers, certain pesticides or sewage sludge.

Meat, eggs and milk must come from animals that have been raised according to specific health and welfare standards. Also, farmers may not treat these animals with antibiotics or growth hormones and must raise them on organic feed. Products with multiple ingredients must contain 95 percent or more organic content.

For years, scientists have been trying to tease out whether organic foods are themselves different than those grown conventionally. Research is beginning to show organic foods can be better — and not only for the people who eat it, organic food articles.

Growing foods organically also can help the environment, new data show. On a farm, pests and weeds can destroy a crop.

So most U. Organic farmers cannot use all of organic food articles same chemicals. They too can use pesticides and weed killers. But none of these chemicals will necessarily stay put.

Some share of them will tend to move off through the soil, air or water. Eventually, these pesticides end up in streams where they can mix, creating a mystery soup. Scientists have been studying how far and how fast pesticides can move through the environment. These data may then point out which animals are at risk of being exposed to the pollutants.

For instance, researchers recently looked at pesticides commonly used on California farms, organic food articles. They found the pesticides in Pacific chorus frogs living in national parks, organic food articles, forests and other locations high in the Sierra Nevada mountains.

In some cases, organic food articles, the frogs lived more than kilometers 62 miles from the nearest farms that had used the chemicals. She's also a hydrologist with the Organic food articles. A hydrologist studies the movement, distribution and quality of water. Discovering that pesticides contaminate frogs is bad news.

And this could alter how the frogs developed. Honeybees also are in trouble. A problem called colony collapse disorder causes seemingly healthy bees to suddenly abandon their hives. The organic food articles bee remains. Without the worker bees, though, the hive eventually dies. As they go around collecting pollen, bees may pick up any pesticides that had been sprayed onto the plants they visited.

Neither can be used on organic farms. The scientists compared bees in these hives to those in hives free of these chemicals.

And they found that even small amounts of the two pesticides triggered a biological change that led to bee deaths. This suggests the pesticides create unintended problems for growers. Farmers need bees to pollinate many crops, including almonds, cherries and broccoli. If too many bees die, less pollination may occur. And this can shrink farm harvests. So even organic farms are allowed to use some pesticides.

These chemicals just supposed to pose less of a risk to bees and other beneficial wildlife. Still, those chemicals approved for use on organic farms are not necessarily harmless. These chemicals controlled a type of insect known as an aphid, organic food articles. That means these organic pesticides may have a worse overall impact on this environment that will conventional ones. To grow, plants need nutrients, organic food articles, especially the elements nitrogen organic food articles phosphorus.

And fertilizers add nutrients to the soil. Organic farmers cannot use these elements if they come from synthetic human-made sources, such as ammonia salts. Instead, the farmers need to find natural fertilizers.

For instance, they may plant beans. These plants naturally increase nitrogen levels in the soil, organic food articles. Crops that are planted after the beans are gone can now use that nitrogen.

With rich, healthy soil, crops also may need fewer pesticides or fertilizers, farmers are finding. Both nitrogen and phosphorus can build up in nearby waterways.

This is called nutrient pollution. Plants and animals need nutrients to thrive. But when large amounts of these elements end up in lakes and oceans, they can cause large growths of algae. Those growths are called algal blooms. They can kill fish and other aquatic life. The problem can be made worse by unpredictable rains. This may be happening in the Midwest, says Lisa Nowell. Inthe Midwest experienced a drought.

The following year it rained. A lot. Rivers overflowed their banks. Towns and fields flooded. All that rain risks washing away fertilizers and other chemicals that had collected in the soil, Nowell says. It was kind of phenomenal. And that can cause real problems organic food articles. Organic farms tend to produce less of that kind of pollution. One reason: These farms often work to build soil that retains more water and that produces less runoff.

Organic farmers also use compost. This soil-enriching mix is usually made from decomposed plantsfood waste and manure. Organic food articles provides nutrients for plants. It also is rich in organic food articles life. Research suggests these microbes are important for the health of soils — and plants, organic food articles. Healthy soils also can help plants take up nutrients and can hold water in the root zone, where plant's most need it. Carr is researching how microbes in compost can help fight plant diseases.

We're taking care of the soil so it can take care of our plants. Many people buy organic food because they think it's healthier. But whether it is remains an open question — even after years of research and debate. Its findings appeared in the Annals of Internal Medicine. More recently, a team of experts in England and elsewhere came to the opposite conclusion. Organic food articles reviewed organic food articles of the research they could find on this question.

The team chose studies for its members to analyze. Organic crops contain, on average, 17 percent more antioxidants than crops grown conventionally, organic food articles, they found. Antioxidants are compounds in many fruits and vegetables, organic food articles. But there is evidence that people who consume foods rich in antioxidants have a lower risk of diseases such as stroke and cancer.

He also was an author of the British Journal of Nutrition study. For some nutrients, organic might be higher, organic food articles. For other nutrients, conventional might be higher. However, farming practices can have the biggest impact on nutritionally dense foods, Benbrook notes. For many people, that's enough reason to buy organic. Developing organic food articles, babies and children are most vulnerable to potential harm, they noted.

The key concern in the advisory was with direct exposure to pesticides. In places like farms and lawns, people may come into direct contact with these chemicals after they have been sprayed.

Autism is one worry. Published in Environmental Health Perspectivesthis study surveyed pregnant women. One-third lived less than 1.
