Why Eat Organic?

Why Eat Organic?

There is an increasing demand globally for organic food. Consumers believe that it is more nutritious and better for the environment than conventionally produced food. So what exactly are the health benefits and is organic really worth the extra money?

What does organic really mean?

Organic growing is generally defined as food produced without artificial or synthetic chemical fertilisers, pesticides, fungicides or weedicides. These farmers don’t use genetically modified components or expose the food to irradiation.

Often organic farming factors in environmentally sustainable farming techniques and takes care of the environment by conserving water, soil and energy.

Crops are usually rotated to prevent depletion of nutrients in the soil and natural farming cycles are incorporated.

Animals raised using these methods are treated humanely and with respect.

They are usually free from lots or cages and not fed any growth-regulating drugs, steroids, hormones or antibiotics.  

What is biodynamic?

Biodynamic agriculture is a related system which recognises a spiritual dimension to farming by incorporating lunar and astrological cycles which are thought to influence the growth of plants and animals. Biodynamic gardeners use special therapeutic preparations for the soil, plants, compost and manure.

Who sets the standards?

Organic and biodynamic standards are set out by The Australian Quarantine Inspection Service (AQIS) and certification is licenced by several private organisations such as the National Association of Sustainable Agriculture, Australia (NASAA) and the Biological Farmers of Australia (BFA). While there are currently no requirements for certification of domestic organic products sold in Australia many organic business choose to do so to promote consumer confidence and to underpin truth in labelling requirements.

When buying organic food don’t be fooled by the phrases “chemical free”, “organic” or “natural” if the proper certification label isn’t displayed. Biodynamic food should also display the Demeter symbol.

Healthy environment

Environmental pollution is a major concern worldwide. Modern farming methods have led to a decline in soil fertility, and in increase in salinity and waterway pollution. The overuse of fertilizers increases algal blooms and waterweeds in lakes and rivers, which in many cases has literally choked them to death. 
Organic farmers aim to minimise damage to the environment by using animal and green manure as well as other safe methods of pesticide and weed control.

Health effects of pesticides

There are many short and long-term effects of pesticide exposure. Many studies have shown that it can increase the risk of leukaemia and lymphoma and cancers of the brain, kidney, breast, prostate, liver, lung and pancreas. A child’s risk of developing leukaemia, Wilms tumour and brain cancer are also increased if their mother was exposed to pesticides during pregnancy. 

Pesticide exposure can also negatively affect our nervous system. Exposure to low levels of pesticides increases the risk of developing Parkinson’s disease by 70%. A number of pesticides have also been shown to negatively affect fertility in males and females.

Glyphosate, a common herbicide marketed under the trade name roundup, is also linked to many adverse health conditions including cancer, depression, pregnancy and reproductive problems, colitis, autism and even celiac disease. It is common agricultural practice to spray crops such as wheat, barley, oats, soy beans, sugar cane and beans for faster and easier harvesting. Unfortunately this leads to contamination of commonly consumed foods and levels of glyphosate in the body can increase leading to ill health.

Nutritional content of organic food

Scientific opinion on the nutritional difference between organic and non-organic food is mixed. Some studies have shown that organic food has the following nutritional advantages:

  • ​​Substantially higher in antioxidants such as phenolic acids, flavanones, stilbenes, flavones, flavonols and anthocyanins. Many of these compounds have been linked to a decreased risk of chronic diseases such as cardiovascular disease, neurodegenerative diseases and certain cancers.
  • Lower pesticide residues. Concentrations of pesticide residues in conventionally produced crops were found to be four times higher than organic crops.​​
  • Higher levels of the antioxidants vitamin C and selenium.
  • Significantly lower levels of the toxic metal cadmium.
  • Lower levels of nitrate and phosphorus
  • Organic meats are 47% higher in omega 3 and polyunsaturated fatty acids due to their high grazing/forage based diets
  • No synthetic food additives such as preservatives, colourings and flavour enhancers are present which can cause reactions in some individuals

Where to buy organic?

Organic food can be found in some supermarkets, green grocers, health food stores, food markets, the internet and certified organic retailers. Online stores that deliver to your door are becoming a popular option as they have a wider variety of products and often guarantee fresh supplies.

Why is organic so expensive?

Organic food is generally more expensive because farms usually operate on a much smaller scale than conventionally produced food. Farming methods are more labour intensive and crop yields are usually smaller.

If we focused on the quality of food rather than the quantity of food and ate less portions, purchasing organic food can be affordable.

Organic farming practices can be used at home at a low cost so that you can supply your own healthy produce either on a small or large scale.

The organic movement offers a healthy, sustainable view of the future by caring for our environment and treating animals in an ethical way. Organic food is  healthier for the people who consume it as it has significantly less residues of pesticides and other synthetic chemicals. Nutrients such as antioxidants, omega 3, vitamin C and selenium are found to be in higher concentrations in organic food compared to non-organic food.
