The food production and style of dining has changed a lot since the 19th

century.

As people started to concern the quality of food, the term “organic food” was first

Introduction to Organic food

The production of organic food is in a sustainable manner.

They are produced according to certain production standards.

For crops, it means they were grown without using artificial

fertilizer. For animals, it means they were reared without

using growing hormones. Also, organic products must not be

genetically modified.

Origin of Organic Food

Modern agriculture have large amounts of chemical inputs

and intensive farming methods. Indeed, it is obvious that

almost the entire history of agriculture consists of what

would be now termed "organic farming", as in previous

centuries there was no technology to modify natural food.

Arguments on organic function

Although lots of researches and information showed that organic product is more

nutritious than inorganic ones, but some still argues on this point with other sound

evidence.

� No conclusive evidence shows that organic food is more

nutritious than is conventionally grown food. And the USDA

--- even though it certifies organic food — doesn't claim that

these products are safer or more nutritious.

� Some experts explain that the dramatic changes in nutrition

value may due to the improvement in weather and soil

condition.

� The experiments carried out are not qualified and the results

may be affected or disrupted, thus become inaccurate.

Buying Tips

development, as well as improving our environment and food quality.

� Buy fruits and vegetables in season to ensure the highest quality.

value are not directly caused by organic farming.

Other useful chemical compounds

by organic methods contain more mineral sources, 14 % more

Vitamin C and 17% more polyphenol, which can control the

amount of cholesterol inside our bodies.

Further discoveries in organic products

The sale of organic food accounts for only 1% of the total food

sales worldwide, and the market is still growing rapidly. The
