Is Organic Really Better for You?


Organic food comes at a much higher price tag than conventionally farmed produce, so you may be asking, “Do I really need to eat organic?” There is no question that eating more fruits and vegetables, organic or conventional, has many health benefits and should be included as a healthy diet. But some recent studies have shown that organic produce may not be more nutritious which may make you question if choosing organic is really worth it. In reality, there is more to the story than just nutrition. Just because organic produce may not be nutritionally superior doesn’t mean you should choose conventional all the time. The answer may actually lie somewhere in the middle. In this blog post, we’ll discuss why it’s important to eat organic produce and which food you may want to avoid if you can’t.

Organic food is becoming increasingly popular as people are waking up to the harsh reality of conventional agriculture: pesticide use, mono-crop farming, soil degradation and water pollution among others. Organic food is grown without synthetic fertilizers or chemical interventions like fungicides and herbicides – which means you don’t have to worry about ingesting these toxic chemicals and known carcinogens from eating these foods. This is the main reason to choose organic over conventional.

In addition to avoiding the toxins, there are more reasons to consider eating organic including environmental impact. Residue from conventional agriculture can seep into rivers and groundwater sources causing environmental damage that can impact our health and the environment, including the animals in that area. Pesticides are not only found in conventionally farmed produce but also wild-caught fish making it difficult to avoid toxins if they are showing up in places we previously thought were safe.

Choosing organic food helps support small local farms who practice sustainable farming techniques instead of big agriculture, which limits our exposure to these toxins and potentially harmful genetically modified organisms (GMOs). Big agriculture is an industry that has a significant impact on both our health and the environment. This form of industrial farming utilizes large amounts of fertilizer, pesticides, and other chemicals that can be hazardous to both humans and animals. Additionally, the large-scale cultivation of crops can lead to soil degradation, air pollution from chemical drift and runoff, water contamination from chemical use, and destruction of habitats for native wildlife. These factors contribute to health issues such as allergies or asthma in humans, as well as known and unknown long-term health effects and long-term damage to ecosystems. The increased use of big agrochemicals also increases the risk of creating resistant strains of weeds and insects which could have far-reaching effects on food production. All the more reason to support the little guys and their clean practices if you can afford to.

Despite all the harm that comes from conventional farming practices, there are some benefits in terms of food production and cost that must be considered. The use of synthetic fertilizers, pesticides and mechanization can help increase crop yields and productivity, which addresses the growing demand for food in a rapidly increasing global population. In addition, conventional farming techniques can be more cost-effective than other methods, as they often rely on the use of cheaper inputs such as the synthetic fertilizers and pesticides. These practices result in more consistent crops and livestock which allows for easier packaging and distribution and can reduce the amount of time and labor required to produce. All of this leads to lower production costs for farmers, which then carries on to the consumer at the grocery store allowing healthy food options to be accessible at all price points.

Since shopping for organic food can get expensive, it helps to know what to look for since not all produce is created equal and some items tend to be more heavily laced with pesticides than others. The produce to look out for includes apples, tomatoes, sweet bell peppers, grapes, spinach, strawberries, potatoes and lettuce. Ensuring proper washing methods for these fruits and vegetables will help reduce your exposure to pesticides but it’s best to opt for organic if possible.

The Environmental Working Group (EWG) has developed a list of the “Dirty Dozen” fruits and vegetables that contain the highest levels of pesticide residue, which should be purchased organically whenever possible. Eating these foods in their conventional form runs the risk of ingestion of potentially harmful chemicals.

On the flip side, some fruits and vegetables have very low levels of pesticide residue even when grown conventionally – these are known as the “Clean Fifteen”. The Clean Fifteen includes avocados, pineapples, onions & garlic (not processed), cabbage & broccoli (not processed), sweet peas (frozen), mangoes & honeydew melons (not pre-cut), kiwi fruit (not pre-cut), cantaloupe melons (previously cut) and eggplant. When purchasing these fruits and vegetables in their conventional form there is little to no risk involved as far as pesticide exposure goes. EWG updates the “Dirty Dozen” and “Clean Fifteen” lists each year.

Eating organic food not only has many health benefits but also provides ecological support by helping maintain good soil health which is necessary for future generations. It is true that conventional farming practices result in more crops available at lower price points giving access to produce for families who cannot afford organic, but if you want to reduce your exposure to pesticides and support sustainable farming practices (and can afford to do so) then adding more organics into your diet is the way to go. If you’re not able to purchase organic, stick to the “Clean 15” when buying produce. Your body (and nature) will thank you for it.

Foundations of a Healthy Diet

The topic of food and nutrition is vast and complex and has been studied for centuries around the globe. In the last 100 years, there have been significant advancements in the study of vitamins and deficiencies, and correlations to disease. What we eat has a profound impact on our health, both in the short and long-term. There are many opinions on the best way to eat healthy, but through studying longevity and disease prevention, it becomes evident that there are a few key foundations present in the most highly regarded diets. These foundations which have been associated with the healthiest populations on the planet, consist of consuming mostly plant-based foods, moderate protein and fat intake, and avoiding excess calories. By following these principles, you can help your body stay healthy and reduce your risk of developing chronic illnesses.  Let’s explore each of these in more detail. 

Primarily Plant-Based
It is recommended that 60-80% of your diet comes from plants, predominantly vegetables, which are nutrient dense and provide vitamins and minerals which are essential to life. In addition, fruits and vegetables are an excellent source of phytonutrients and antioxidants, which promote health and have been associated with disease prevention. These nutrients are important because they neutralize cell-damaging free radicals in the body and have anti-cancer properties. They are also a great source of enzymes, prebiotics and fiber, which contribute to a healthy gut microbiome and have been associated with regulating cholesterol and blood pressure and even decreasing chances of developing colon cancer. Plants can be a great source of all three macronutrients: protein, fat and carbohydrates.

Carbohydrates should make up 40-75% of a diet with the primary source coming from plants as mentioned above. When you think of carbs, think whole foods rather than bread or processed food, which are less healthier options. The quantity and source of carbs will vary based on whether or not you are trying to gain or lose weight.  Those looking to lose weight will incorporate primarily plants to fulfill their carbohydrate needs.

Moderate Fat Intake
Fat should make up between 10-35% of the diet depending on genetic factors, which can be found through genetic testing or experimentation. A diet that is considered high in fat would be in the 30-35% range, which is far below the 70% range that is suggested with ketogenic diets. That’s not to say that a keto diet isn’t effective, it can actually be a great tool for quick fat loss and regulating blood sugar, but it can lead to consequences when used long term. We’ll revisit this topic in a future post.

There are individuals that can thrive on a high fat diet because their gene makeup allows them to tolerate and process the fats. This group is a small subset of the population, making up around 5%. The gene responsible for this ability to tolerate the increase in fats is ApoE, which regulates lipid levels in the blood.  The ApoE2 isoform of the gene could potentially offer protective effects against a higher fat diet, so this group could do well closer to 30% range of fat in the diet. The majority of the population should strive to stay much below that limit to prevent inflammation, which is the catalyst for many diseases that are prevalent in society including heart disease and diabetes.  ApoE4 is associated with increased risk for cardiovascular disease and Alzheimer’s, so those with this form should stay on the lower end of the recommendations with the primary source of fat coming from plant sources.  The population with ApoE4 present is around 20%.  The rest of the population will benefit from keeping their fat in the 15-25% range.

Moderate Protein Intake
The healthiest diets consist of protein intake between 5-20% with animal-based protein limited to 5% of the diet. Strive for no more than one serving of animal protein per day, which is roughly 4-8 oz. The remainder can come from plant-based sources including beans, chickpeas, lentils or protein powders such as rice or pea protein.

Diets high in animal protein have been associated with a higher risk of developing cancer. One research study published in the journal Cell Metabolism, showed a fourfold increase in cancer in adults who consumed large amounts of protein, which was comparable to the risk associated with smoking. The risk nearly vanished if the main source of protein was plant-based. Animal protein increases the levels of growth factor in the body, which can feed cancer cells. A diet lower in animal protein has a positive impact on lifespan.

Bio-individuality tells us that there is no one size fits all when it comes to a proper diet. Our lifestyle and genes will ultimately determine which side of the range we should adhere to for each of the macronutrients: carbohydrates, fats and protein. But there is no question that plant-based foods, such as fruits and vegetables are the foundation of a healthy diet. Following the research-backed suggestions in this article will help the majority of people establish healthy eating practices and can be used as a general guide for healthy eating.

If your goal goes beyond general health maintenance such as weight loss, following a prescribed diet plan could be helpful. Ideally diets should be used for a short period of time, such as a 6-12 week period. Then you should transition back to the foundational eating plan to make sure you are creating balance and meeting the nutritional needs for your body.
