During large portions of the year it is usually possible to find food grown close to home at places such as a farmer's market. Financial: Money stays within the local economy. More money goes directly to the farmer, instead of to things like marketing and distribution.
Transportation: In the U. Or the food is highly processed in factories using preservatives, irradiation, and other means to keep it stable for transport. Freshness: Local food is harvested when ripe and thus fresher and full of flavor. Some small local farmers use organic methods but may not be able to afford to become certified organic.
Visit a farmer's market and talk with the farmers to find out what methods they use. The ongoing debate about the effects of GMOs on health and the environment is a controversial one.
For example, much of the sweet corn consumed in the U. is genetically engineered to be resistant to the herbicide Roundup and to produce its own insecticide, Bt Toxin. GMOs are also commonly found in U.
crops such as soybeans, alfalfa, squash, zucchini, papaya, and canola, and are present in many breakfast cereals and much of the processed food that we eat.
If the ingredients on a package include corn syrup or soy lecithin, chances are it contains GMOs. The use of toxic herbicides like Roundup glyphosate has increased 15 times since GMOs were introduced.
While the U. Food and Drug Administration FDA and the biotech companies that engineer GMOs insist they are safe, many food safety advocates point out that no long term studies have ever been conducted to confirm the safety of GMO use, while some animal studies have indicated that consuming GMOs may cause internal organ damage, slowed brain growth, and thickening of the digestive tract.
GMOs have been linked to increased food allergens and gastrointestinal problems in humans. While many people think that altering the DNA of a plant or animal can increase the risk of cancer, the research has so far proven inconclusive.
As mentioned above, one of the primary benefits of eating organic is lower levels of pesticides. However, despite popular belief, organic farms do use pesticides.
The difference is that they only use naturally-derived pesticides, rather than the synthetic pesticides used on conventional commercial farms. While natural pesticides are believed to be less toxic, some have been found to have health risks.
That said, your exposure to harmful pesticides will likely be lower when eating organic. Most of us have an accumulated build-up of pesticide exposure in our bodies due to numerous years of exposure.
Some studies have indicated that the use of pesticides even at low doses can increase the risk of certain cancers , such as leukemia, lymphoma, brain tumors, breast cancer and prostate cancer. Children and fetuses are most vulnerable to pesticide exposure because their immune systems, bodies, and brains are still developing.
Exposure at an early age may cause developmental delays, behavioral disorders, autism, immune system harm, and motor dysfunction.
Pregnant women are more vulnerable due to the added stress pesticides put on their already taxed organs. Plus, pesticides can be passed from mother to child in the womb, as well as through breast milk.
Rinsing fresh produce reduces but does not eliminate pesticides. Peeling sometimes helps, but valuable nutrients often go down the drain with the skin.
The best approach: eat a varied diet, wash and scrub all produce thoroughly, and buy organic when possible. Organic food is often more expensive than conventionally-grown food.
But if you set some priorities, it may be possible to purchase organic food and stay within your food budget. Some types of conventionally-grown produce are much higher in pesticides than others, and should be avoided when possible.
Others are low enough that buying non-organic is relatively safe. According to the Environmental Working Group, a nonprofit organization that analyzes the results of government pesticide testing in the U.
In the U. These practices can have health consequences for both the animals themselves and people consuming their meat, eggs, or milk. Shop at farmers' markets. Many cities, as well as small towns, host a weekly farmers' market, where local farmers sell their produce at an open-air street market, often at a discount to grocery stores.
Join a food co-op. A natural foods co-op, or cooperative grocery store typically offers lower prices to members, who pay an annual fee to belong. Local and organic! Buy in season. Fruits and vegetables are cheapest and freshest when they are in season. Find out when produce is delivered to your market so you're buying the freshest food possible.
Shop around. Compare the price of organic items at the grocery store, the farmers' market, online, and in other venues even the freezer aisle. Remember that organic doesn't always equal healthy. g, Al 4 C 3 and CaC 2 and "covalent" carbides, e.
B 4 C and SiC , and graphite intercalation compounds, e. Other compounds and materials that are considered 'inorganic' by most authorities include: metal carbonates , simple oxides of carbon CO , CO 2 , and arguably, C 3 O 2 , the allotropes of carbon, cyanide derivatives not containing an organic residue e.
Halides of carbon without hydrogen e. Nickel tetracarbonyl Ni CO 4 and other metal carbonyls are often volatile liquids, like many organic compounds, yet they contain only carbon bonded to a transition metal and to oxygen, and are often prepared directly from metal and carbon monoxide.
Nickel tetracarbonyl is typically classified as an organometallic compound as it satisfies the broad definition that organometallic chemistry covers all compounds that contain at least one carbon to metal covalent bond; it is debatable whether organometallic compounds form a subset of organic compounds, however.
For example, the evidence of covalent Fe-C bonding in cementite , [8] a major component of steel, places it within this broad definition of organometallic, yet steel and other carbon-containing alloys are seldom regarded as organic compounds. Thus, it is unclear whether the definition of organometallic should be narrowed, whether these considerations imply that organometallic compounds are not necessarily organic, or both.
Metal complexes with organic ligands but no carbon-metal bonds e. Likewise, it is also unclear whether metalorganic compounds should automatically be considered organic. The relatively narrow definition of organic compounds as those containing C-H bonds excludes compounds that are historically and practically considered organic.
Neither urea CO NH 2 2 nor oxalic acid COOH 2 are organic by this definition, yet they were two key compounds in the vitalism debate. The IUPAC Blue Book on organic nomenclature specifically mentions urea [9] and oxalic acid.
Mellitic acid , which contains no C-H bonds, is considered a possible organic substance in Martian soil. A slightly broader definition of the organic compound includes all compounds bearing C-H or C-C bonds. This would still exclude urea. Moreover, this definition still leads to somewhat arbitrary divisions in sets of carbon-halogen compounds.
For example, CF 4 and CCl 4 would be considered by this rule to be "inorganic", whereas CHF 3 , CHCl 3 , and C 2 Cl 6 would be organic, though these compounds share many physical and chemical properties.
Organic compounds may be classified in a variety of ways. One major distinction is between natural and synthetic compounds. Organic compounds can also be classified or subdivided by the presence of heteroatoms , e.
Another distinction, based on the size of organic compounds, distinguishes between small molecules and polymers. Natural compounds refer to those that are produced by plants or animals. Many of these are still extracted from natural sources because they would be more expensive to produce artificially.
Examples include most sugars , some alkaloids and terpenoids , certain nutrients such as vitamin B 12 , and, in general, those natural products with large or stereoisometrically complicated molecules present in reasonable concentrations in living organisms.
Further compounds of prime importance in biochemistry are antigens , carbohydrates , enzymes , hormones , lipids and fatty acids , neurotransmitters , nucleic acids , proteins , peptides and amino acids , lectins , vitamins , and fats and oils.
Compounds that are prepared by reaction of other compounds are known as " synthetic ". Most polymers a category that includes all plastics and rubbers are organic synthetic or semi-synthetic compounds.
Many organic compounds—two examples are ethanol and insulin —are manufactured industrially using organisms such as bacteria and yeast.
Many such biotechnology -engineered compounds did not previously exist in nature. A great number of more specialized databases exist for diverse branches of organic chemistry. Contents move to sidebar hide. Article Talk.
