Concerned shoppers fill their carts with organic fruits and vegetables worrying that they will put their family at risk if they buy the regular produce. Other shoppers skip the produce all together because they worry about pesticides, but can’t afford the organic varieties. Unfortunately, in the hype of organic foods, many of us have lost sight of the fact that eating produce is much more important than worrying about organic versus conventionally grown fruits and vegetables.
The risks associated with poor fruit and vegetable intake are far more dangerous than the risk of eating fruits and vegetables grown conventionally. In this article, I’ll review what you need to know about organic fruits and vegetables, including if they’re worth the impact on your wallet!
Eat your fruits and vegetables!
It is well-accepted that fruits and vegetables reduce the risk of heart disease and some cancers, lower blood pressure, help to regulate blood sugar, and promote good digestive health. The fact that many people feel that they must eat less or none at all because they can’t afford organic produce puts them in a very bad position.
On the other hand, others spend hundreds of dollars buying organic produce with limited evidence that they are receiving a benefit that is worth all of that green coming from their pockets. As a dietitian, my biggest concern is whether or not you are eating fruits and vegetables. Even the Environmental Working Group (EWG) concedes that eating fruits and vegetables of any kind is far more important than whether or not you are exposed to pesticides.
It’s all about balance and dosage
Now, consider this. Many essential nutrients in our diets have the potential to be toxic. One example is potassium. Potassium is extremely important and most people recognize it as a good electrolyte found in many fruits and vegetables. Did you know that too much potassium in the body is lethal? Yes, it is highly unlikely that your body would reach lethal amounts of potassium from eating too many bananas. However, people who are in kidney failure and cannot clear out extra potassium are at risk. In fact, potassium can be given as a lethal injection.
Have you ever heard of water intoxication? Drinking large amounts of water without balancing your intake with electrolytes will lead to hyponatremia, which can be fatal. This has happened to marathon runners, unfortunately. On the other hand, we think of sodium as being harmful. Well, most Americans do get way too much sodium in their diets. However, it is still pretty darn important. Remember the fatal hyponatremia we just talked about? So, it is all about balance and dosage.
The risk of pesticides
In a study performed to determine the risk of pesticides on produce, Winter and Katz compared the average daily dose of pesticides found on various fruits and vegetables to the chronic reference dose developed by the Environmental Protection Agency. The chronic reference dose indicates the upper limit of a pesticide that could be consumed daily for a lifetime without any observable difference. On all of the fruits and vegetables examined, the ten most common pesticides were more than 1000 times lower than the chronic reference dose.1 I don’t know about you, but that makes it hard for me to justify the extra cost to purchase organic produce.
Keep in mind that organic does not mean pesticide-free. Pesticides are often used, but they are naturally derived rather than synthetically derived2. The word “natural” does not guarantee that it is healthy. After all, remember that plain water is natural and essential, but could become poisonous in a dose that is too large.
So, what about the nutrient content of organic versus conventionally grown produce? A study published in the Annals of Internal Medicine examined 17 human studies and 223 studies that took a look at nutrients and contaminants in fruits and vegetables. During this deep dive into the data, some differences were found in urinary pesticide levels in children who consumed organic produce, but those differences were not found in adults. The nutritional content of organic versus conventionally grown produce was largely similar. The conclusion of this study stated that there was not enough of a difference between the two groups to state that organic foods are more nutritious. However, they did report that consumption of organic foods would reduce the intake of pesticides and antibiotic-resistant bacteria3.
Some experts believe that organic produce may contain higher levels of antioxidants. That would certainly be a benefit. Is that benefit worth the higher price tag? The answer to that may be in your wallet.
Ways to reduce your pesticide consumption
The main idea is to eat more fruits and vegetables, be it conventional or organic. Whether you decide to shop organic or not, you can take some steps to reduce the number of pesticides you are consuming. According to the National Pesticide Information Center (NPIC), you should wash your produce under running water and dry it with a clean cloth towel or paper towel. Firm vegetables, such as potatoes and melons, should be scrubbed well. Eating a variety of fruits of vegetables is also a great way to ensure that you aren’t getting too much of one particular pesticide4. That is also a great nutritional tip as it will vary the nutrients you are getting as well!
Have you ever wanted to grow your own garden? This could be a fun teaching tool for kids and you can control exactly what is being sprayed on your fruits and vegetables. If that doesn’t sound doable for you, the NPIC suggests visiting a farmers’ market so that you can discuss what is used on the produce with the farmers3. This is also a great way to decrease the carbon footprint needed to ship fruits and vegetables across the country.
The real tragedy is that only 1 in 10 adults get the recommended 1 ½ – 2 cups of fruit and 2-3 cups of vegetables per day5. That means that 90% of American adults are NOT getting enough fruits and vegetables. There is an upward trend of children eating whole fruit, which is awesome news, but vegetable intake isn’t getting any better6.
To raise children who are produce consumers, parents need to be produce consumers themselves and make it available to children. Whether you want to provide organic or conventionally grown produce, stock it in your refrigerator and put it on the table! Find new ways to cook it, eat it, and enjoy it!
