  • Choose Organic For Superior Health Benefits

    You may have heard that 'going organic' is a healthy choice for the farmers, the environment, and your own health. But do you really understand why it's such a positive choice?

    This article series explores the benefits of choosing organic.

    Reason: Organic food offers superior health benefits

    Some of my previous articles have highlighted health benefits that can be obtained from choosing organic. These range from helping to protect the body from cancer1 to explaining the profound benefits of nurturing healthy soil2 to sharing some of the potentially toxic processes3 and chemicals4 that conventional food can be subjected to.

    In some ways I was reluctant to straight out claim that organic food is more nutritious because this is not always true. There are organic food products on the market that have been highly processed into something that is quite far removed from the crop they started from. Throughout this process valuable nutrients are lost and the end result becomes less nutritious for our bodies.

    It is also worth mentioning that nutrient levels in the soil can vary a lot within both conventional and organic crops depending on how the farmer or grower approaches soil health.

    Additionally, it is important to compare nutrient levels between the same types of crops because nutrient levels vary between types of plants and specific varieties in both conventional and organic growing.

    As I mentioned in an earlier article5 soil health is of the utmost importance in organic farming. This is a crucial factor in successful organic growing because quick fix solutions such as synthetic chemical fertilizers are not allowed to be used. Nurturing the soil creates a healthy soil microbiome, which grows healthy plants, which in turn help people to be healthy.

    Plants need to use their own inbuilt protection mechanisms to ward off pests because these same protection mechanisms are what provide us with antioxidants for our bodies. If plants are routinely being sprayed with synthetic pesticides the plant loses the requirement to use these amazing natural protection mechanisms. Along with that, the antioxidants that have been linked to optimal health in humans are severely depleted.

    There are always going to be studies that show no difference in antioxidant levels between conventional and organic crops. Some studies are repeated over again until beneficial results are found to support whatever corporate giant is funding the study. However there certainly is evidence out there that organically grown crops have higher nutritional content.

    A large study carried out meta-analyses based on 343 peerreviewed publications that indicate statistically significant and meaningful differences in composition between organic and non-organic crops/crop-based foods. The concentrations of a range of antioxidants such as polyphenolics were found to be substantially higher in organic crops/crop-based foods.6

    The 'look' of some organic produce can sometimes put people off eating it because it doesn't seem as appealing. In my experience, I have often found that our customers are pleasantly surprised by how wonderful their 'ugly' looking fruit tastes, and there is also evidence to suggest that it could contain superior nutritional qualities.

    Studies have found that apples with 'scabs' on the skin or leaves contained higher antioxidants (phenolic compounds) than scab-free apples and apple leaves.7,8 Similarly, higher concentrations of resveratrol (an antioxidant) have been found in grape leaves following fungal infection or exposure to ultraviolet light.9

    These results all connect back to the plant needing to work hard to fight for its survival. The inbuilt protective mechanisms kick in and these same protection mechanisms are what provide us with antioxidants. To remind you once more, a plant that has been sprayed with synthetic pesticides does not require these mechanisms for protection from pests, and therefore is unlikely to have antioxidants in the same concentrations that a plant which has not been subjected to synthetic pesticides will have.

    With this in mind, give that 'ugly' looking fruit a bit of a chance—you might be pleasantly surprised by the taste and it's highly likely that it's better for you too.

  • Why Choose Organic?

    Why Choose Organic? Elly McGuinness

    You may have heard that ‘going organic’ is a healthy choice for the farmers, the environment, and your own health. But do you really understand why it’s such a positive choice? This article series explores the benefits of choosing organic.

    Reason 1: Glyphosate
    You may be aware that organic food and products are produced without the use of synthetic fertilizers, pesticides, herbicides or chemicals. Advocates of conventional farming (the type that does allow use of these artificial substances) argue that recommended levels of these chemicals are not exceeded.

    This statement may be true for one chemical in one product but it does not consider the sheer number of potentially toxic chemicals that we are subjected to in modern society—in our food, our water, in the materials we use to make products and clothing, and in the air we breathe.

    A chemical may be tested and found to be safe at a certain level, but it is unlikely that the full cocktail of chemicals contained in a product have been tested. Molecular biologist Professor Gilles-Eric Seralini has demonstrated that the full formulations of pesticides are much stronger than the declared active ingredient. Additionally, the ‘active’ ingredient may not be the most toxic ingredient in pesticide formulations.1

    Coupled with these issues, there is little consideration for variations in sensitivity between individuals, nor for the consequences of being exposed to so many different chemicals over the course of a day, or a lifetime.

    Glyphosate is a chemical under hot discussion in the farming world. Being on the market in the form of the active ingredient in the widely used herbicide Roundup, virtually all conventional produce and food products contain traces of this chemical. As with all subjects of debate, there are many studies that claim Roundup herbicide poses no risk to humans.2

    However, in March 2015 the World Health Organization's International Agency for Research on Cancer classified glyphosate as “probably carcinogenic in humans” (category 2A) based on epidemiological studies, animal studies, and in vitro studies.3,4,5

    Advocates for organic farming believe it is wise to err on the side of caution—who wants to risk a build-up of toxic residue that could lead to serious health problems? It is much safer to ban ‘questionable’ chemical ingredients and to find a proven safe alternative than to live by the mantra of ‘innocent until proven guilty.’

    The links between glyphosate and a wide range of health concerns and conditions are becoming increasingly evident. Dr. Stephanie Seneff, a senior research scientist at the Massachusetts Institute of Technology (MIT), has found strong links between glyphosate use, and the rise in celiac disease. She explains that the villi in the gut are destroyed by glyphosate, which reduces the person’s ability to absorb vitamins and minerals and can result in gut problems.6

    Glyphosate has been highlighted as a potential endocrine disruptor7 and has shown a strong correlation with the increased incidence of many diseases, from cancer to dementia, to autism.8,9,10 The World Health organization lists the adverse health effects caused by glyphosate as airway, skin, and mucous membrane irritation, abdominal, pain, nausea, vomiting, shock, dyspnea, respiratory failure.11

    For consumers who are not convinced about the safety of food production methods using synthetic chemicals such as glyphosate, the only ways to currently drastically reduce exposure are by choosing certified organic produce and products, growing your own, or by getting food from a local farmer who you know is not using these chemicals.12,13,14

    For those who are not sure how to start shifting from a conventional to an organic diet, or who have concerns around personal budgeting restraints, a good place to start making changes is by focusing on the ‘dirty dozen’— a list of the twelve foods in New Zealand that have been identified as having the highest pesticide residues.

    Reason 2: Healthy soil, healthy body
    Many people are now choosing organic as one way to help optimize their health and wellbeing. The vitamin and mineral content of fresh produce and other foods will vary based on how the soil is cared for, the environment they are grown in, and how they are processed, among other things.

    In organic farming, caring for the soil is of the utmost importance, because it forms the basis for health, for all life forms. As Sophie Grigson and William Black explain, “Healthy soil encourages healthy plants, plants which are strong and disease resistant, which means there is less need for artificial pesticides in organic production.” Their book “Organic—a new way of eating” highlights the fact that if we feed the soil, the plants will look after themselves.15

    Sally Fallon reiterates this in her book “Nourishing Traditions,” when she explains that nitrogen fertilizers used in conventional (non-organic) farming produce high yields, in part by pulling minerals from the soil. In turn, the food suffers because the vitamin and mineral contents are depleted. She explains that vitamin and mineral content between conventional and organic crops can vary hugely, and that some commercially raised oranges have been found to contain NO vitamin C!16

    The old saying ‘you are what you eat’ really does ring true. If you are consuming food that was once a sickly animal who was fed routine courses of antibiotics and a genetically engineered diet of pesticide sprayed grains that it is unable to digest, how healthy do you think you will be?

    If you are eating food that has been sprayed copious times with a herbicide that has been engineered to kill EVERYTHING around it, except that particular crop, how do you think this affects the health of the soil, and the subsequent health of your body? Similarly, with the skin being the largest organ in the body, and readily absorbing anything you rub on it, have you considered what is entering your system via this method (by way of creams and lotions)?

    Yes, our bodies are amazing, and yes they can process and eliminate a certain degree of ‘rubbish.’ But, when they become overloaded they are unable to summon the resources required to neutralize the onslaught of poisons entering them. Therefore it makes sense to limit our intake of toxins wherever we are able to do so; for example by making organic choices.

    Organic farming helps ensure you are receiving the best quality for your body, allowing your cells to be as healthy and strong as possible. Growth hormones, protein rich feeds and the routine use of antibiotics are not allowed, nor are synthetic chemical fertilizers, fungicides, herbicides or pesticides.

    If you consider health as a holistic word encompassing people, animals, and the planet, then choosing organic is a positive step in this direction.
