Not Your Grandmother’s Organic Food

Not Your Grandmother’s Food | Organic | The Paleo Diet

In honor of National Farmers Market Week,1 it’s time we discuss how our food has changed in the past 100 years.2 From soil degradation,3 to fertilizer use,4 to pesticides,5 to genetically modified organisms (GMOs),6 and to why “organic and local” is always the best option.7

Soil erosion is one of the most serious environmental and public health problems facing human society.8 Studies show soil is being lost from agricultural areas 10 to 40 times faster than the rate of soil formation,9 which could be consequentially disastrous for the human race.

Economically, soil erosion costs roughly $37.6 billion, annually.10 Another cause for concern is declining nutrient density. Three studies of historical food composition data found declines of 5% to 40% (or more) in minerals of vegetables.11

Nutrient Concentrations

Apparent changes in nutrient concentrations in 20 vegetables and 20 fruits with 95% confidence intervals (partially recalculated from Mayer, 1997; U.K. data, 1930s to 1980s).

Eighty-year changes in nutrient concentrations found in a study of 45 maize cultivars grown side by side in Iowa and California (means ± 95% confidence intervals).

Fertilizers are made largely from nitrogen and hydrogen.12 These two elements are combined to make anhydrous ammonia.13 This is the basis for all synthetic nitrogen fertilizers.14 The hydrogen source in this process is natural gas, a non-renewable resource.15 The high cost of fertilizer production is also largely in part due to hydrogen.16 So, our current system, which allows us to produce enough food for our ever-expanding population,17 is reliant on a non-renewable fossil fuel.18 Currently, global hydrogen production is 48% from natural gas, 30% from oil, and 18% from coal.19

Food for a hungry world. Food grown with nitrogen fertilizers feeds an estimated 2 billion people worldwide. Areas including Asia are becoming increasingly dependent on such fertilizers, to the detriment of the environment.

We have all heard the adage “if a little is good, a lot more would be better.” Despite the documented negative effects of pesticide use,20 they continue to still be used in large amounts. The rampant use of these chemicals catastrophically affects humans, and other life forms.21

GMOs are still relatively new, in the grand scheme of science and agriculture,22 and while some skeptics question evidence of harm, people continue to fight tooth and nail to stop foods from being genetically altered, or at least labeled as such.23 In 2012, 17.3 million farmers grew genetically engineered crops across 170 million hectares.24 One of the best examples of harm, coming from GMOs, comes from regulators who discovered Gene VI, which has been posited as “unsafe for human consumption.”25, 26

CaMV-Genome

54 out of 86 different transgenic events (unique insertions of foreign DNA) in the US food supply contain portions of this gene. Researchers themselves concluded that this “might result in unintended phenotypic changes.” The repercussions are undeniable.

So, what is the best option for consumers? Well, in the spirit of this celebratory week, local and organic will almost always produce the best results.27 Sadly, this is sometimes impacted by socioeconomic status.28 However, in a recent study researchers found the healthiest diets cost about $1.50 more per day than the least healthy diets.29 “Food deserts” are common, these days.30 Small, local, food stores can have a positive impact on vegetable intake, especially in urban areas.31

Adopting a Paleo Diet will help keep your food local, organic, and hopefully free of pesticides and GMOs. Try to celebrate the farmer’s market every week, not just one week out of the year. Real people, with good intentions, grow our best food. Voice your opinion with your hard-earned dollar, and support them.
