Is it really worthwhile to spent more money on locally grown organic fruits and vegetables than non-organic fruits and vegetables? The answer is a resounding "YES!"Organic grown foods have significantly more vitamins, antioxidants and secondary metabolites such as phenolic compounds than non-organic foods. These compounds provide protective health benefits and lower the risk of cancer, cardiovascular disease, type two diabetes, hypertension and many other chronic health conditions (Romagnolo & Selmin, 2017; Wilson et al., 2017; Oliveira et al., 2013; Surh & Na, 2008). We are what we eat--we can pay for it now and optimize our health or pay more later when our health has been compromised.
The three reasons why fresh organic food is better are:
- Fresh foods lengthen lifespan.
- Organic foods have more vitamins, minerals, antioxidants and secondary metabolites than non-organic foods.
- Organic foods reduce exposure to harmful neurotoxic and carcinogenic pesticide and herbicides residues.
With the advent of chemical fertilizers farmers increased crop yields while the abundant food became less nutritious. The synthetic fertilizers do not add back all the necessary minerals and other nutrients that the plants extract from the soil while growing. Modern chemical fertilizers only replace three components--Nitrogen, Phosphorus and Potassium--of the hundred of components necessary for nutritious food. Nitrogen (N) which promotes leaf growth; Phosphorus (P which development of roots, flowers, seeds, fruit; and Potassium (K) which promotes strong stem growth, movement of water in plants, promotion of flowering and fruiting. These are great to make the larger and more abundant fruits and vegetables; however, the soil is more and more depleted of the other micro-nutrients and minerals that are necessary for the plants to produce vitamins and anti-oxidants. Our industrial farming is raping the soils for quick growth and profit while reducing the soil fertility for future generations. Organic farms have much better soils and more soil microbial activity than non-organic farm soils which have been poisoned by pesticides, herbicides, insecticides and chemical fertilizers (Mader, 2002; Gomiero et al, 2011).

1. Fresh young foods lengthen lifespan. Old foods may be less nutritious than young food. Recent experiments with yeast, flies and mice discovered that when these organisms were fed old versus young food (e.g., mice were diets containing the skeletal muscle of old or young deer), the organisms' lifespan was shortened by 18% for yeast, 13% for flies, and 13% for mice (Lee et al., 2017). Organic foods such as potatoes, bananas and raisins improves fertility, enhances survival during starvation and decreases long term mortality for fruit flies(Chhabra et al, 2013).

In addition, eating lots of fruits and vegetables decreases our risk of dying from cancer and heart disease. In a superb meta-analysis of 95 studies, Dr. Dagfinn Aune from the School of Public Health, Imperial College London, found that people who ate ten portions of fruits and vegetable per day were a third less likely to die than those who ate none (Aune et al, 2017). Thus, eat lots of fresh and organic fruits and vegetables from local sources that is not aged because of transport.
2. Organic foods have more vitamins, minerals, antioxidants and secondary metabolites than non-organic foods. Numerous studies have found that fresh organic fruits and vegetables have more vitamins, minerals, antioxidants, and secondary metabolites than non-organic ones. For example, organic tomatoes contain 57 per cent more vitamin C than non-organic ones (Oliveira et al 2013) or organic milk has more beneficial polyunsaturated fats non-organic milk (Wills, 2017; Butler et al, 2011). Over the last 50 years key nutrients of fruits and vegetables have declined. In a survey of 43 crops of fruits and vegetables, Davis, Epp, & Riordan, (2004) found a significant decrease of vitamins and minerals in foods grown in the 1950s as compared to 1999 as shown in Figure 1 (Lambert, 2015).

3, Organic foods reduce exposure to harmful neurotoxic and carcinogenic pesticide and herbicides residues. Even though, the United States Department of Agriculture (USDA) and the United States Environmental Protection Agency (EPA) state that pesticide residues left in or on food are safe and non-toxic and have no health consequences, I have my doubts! Human beings accumulate pesticides just like tuna fish accumulates mercury--frequent ingesting of very low levels of pesticide and herbicide residue may result in long term harmful effects and these long term risks have not been assessed. Most pesticides are toxic chemicals and were developed to kill agricultural pests -- living organisms. Remember human beings are living organisms. The actual risk for chronic low level exposure is probably unknown; since, the EPA pesticide residue limits are the result of a political compromise between scientific findings and lobbying from agricultural and chemical industries (Portney, 1992). Organic diets expose consumers to fewer pesticides associated with human disease (Forman et al, 2012).
Adopt the precautionary principle which states, that if there is a suspected risk of herbicides/pesticides causing harm to the public, or to the environment, in the absence of scientific consensus, the burden of proof that it is not harmful falls on those recommending the use of these substances (Read & O'Riordan, 2017). Thus, eat fresh locally produced organic foods to optimize health.
