There's an implicit understanding that organic foods are healthier for you to eat, but the reality of organic food is a little trickier. First of all, there's a hugely common misunderstanding of the true nature or purpose of organic food in that it's not about making you healthier (you ego-centric foodie, you).
Instead, it's about a type of food cultivation that preserves the soil and hopefully makes for a cleaner environment. If, in doing so, it makes you healthier, great, but it's more about a recycling of resources that protects the environment, enhances soil and water quality, and protects wildlife.
That being said, there are definitely a few health advantages to eating organic, but the correlations between the food and your health aren't as impressive as both science and the lay press have made them out to be.
Here are 5 perceptions about organic foods, followed by the facts:
1 – Organic foods contain more vitamins.
Sorry to say, but the established nutritional difference between organic and conventional foods is really small, if it exists at all. Meta analyses of organic food studies suggest that they might contain more vitamin C, but for everything else, it's a wash.
It is true, however, that organic foods contain a slightly greater concentration of polyphenolic compounds – plant chemicals that might play a role in preventing certain diseases like cancer and cardiovascular disease.
2 – Organic foods contain more healthy fats.
Organic meat and assorted dairy products (milk, cheese, etc.) have roughly 50% higher omega-3 fatty acids than conventional products. As far as eggs, we might understandably believe they have more omega-3 fatty acids in them, but it's yet to be documented.
However, these products constitute a pretty small proportion of the average diet. In other words, if you're counting on meat or dairy to make up for any deficiencies in omega-3 levels (instead of fish or fish oil supplements), you're likely going to stay deficient.
3 – Organic foods contain fewer pesticides.
This is the one category where organic foods are unequivocally better than conventional foods. Of the over 900 pesticides in use worldwide, there are at least 100 of them that can cause adverse neurological effects in adults, and an untold number may plausibly play a role in a variety of cancers. The fewer you ingest, the better.
But it's not true that organic foods are entirely pesticide-free. There are 25 pesticides that have gotten a waiver and are allowed in organic farming.
4 – There's less of a chance that organic will cause food poisoning.
It'd be nice if that was true, but bacteria like organic food just as well as conventionally grown food. There's also no reason to believe organic foods would contain fewer mycotoxins (toxins from fungi) than conventional food because molds result as a result of post-harvest storage and processing.
5 – Organic foods are healthier in general.
There haven't been too many human studies in this area, but the ones that have shown indications that organically grown food may lead to fewer childhood allergies, less adult diabetes and obesity, and fewer cases of non-Hodgkin's lymphoma.
However, there's a "confounding factor" to consider: People who choose to eat organically presumably already lead a healthier lifestyle with a higher consumption of fruits, vegetables, and whole grains. Case in point, it's probably rare to see a heroin addict who insists on organic foods.
It also has to be said that some studies have shown no real difference in the cancer rates between consumers of organic and conventional food (and one study even showed an increase in cancer rates from organic foods), but here we're presented with another confounding factor: Many people, after being diagnosed with cancer, adopt organic food practices and end up checking the cancer box on surveys, which leads to false assumptions.
So did they get cancer while eating a diet rich in organic foods, or did they get cancer and then switch over? Survey studies have trouble teasing the two categories apart.
How to Use This Info
While the heath differences between organic and conventionally grown food aren't as dramatic as one might hope, you should still buy them and eat them, providing you have enough money to do so. It's marginally better for you, and it's a whole lot better for mama earth.
Conversely, if you can't afford organic foods, there's no need to curse your proletariat status. Just eat conventionally grown produce and meat and once your lotto numbers hit, go for the big O.
