Why Choosing Organic Foods Matters
Over the past few decades, the use of agricultural chemicals has skyrocketed. While conventional farming methods have made food more abundant, they’ve also introduced a growing concern: chronic exposure to pesticides and herbicides in our daily diet. Many clients I work with are surprised to learn that even foods marketed as “healthy” or "natural" can be heavily treated with chemical residues that affect our nervous, immune, and hormonal systems, gut health, and overall long-term vitality.
Understanding the Problem: Hidden Chemicals in Common Foods
Pesticides like glyphosate, paraquat, and neonicotinoids are among the most widely used agricultural chemicals in the United States.
Glyphosate, the active ingredient in Roundup, is applied to millions of acres of crops like wheat, corn, oats, and soybeans. Even non-GMO crops are often sprayed right before harvest to speed drying—a practice called desiccation. While U.S. regulatory agencies like the EPA continue to classify glyphosate as safe when used as directed, independent studies have linked chronic exposure to a variety of potential health issues.
Paraquat, an herbicide banned in over 30 countries, has been linked to neurodegenerative diseases such as Parkinson’s.
Neonicotinoids, a class of insecticides, not only affect pollinators like bees but have been associated with endocrine disruption and developmental concerns in humans.
While the levels in any single food may be small, the cumulative exposure from eating these chemicals every day can add up, especially over years or decades. Children, pregnant women, and those with chronic illness or chemical sensitivities are particularly vulnerable.
The Health Risks of Chronic Exposure
Chronic pesticide exposure has been associated with a range of health issues including:
Hormonal disruption (affecting thyroid and reproductive health)
Gut microbiome imbalance
Neurological effects such as brain fog, fatigue, and developmental delays
Increased cancer risk, particularly with glyphosate (classified by the World Health Organization as a “probable human carcinogen”)
Immune system dysregulation and increased inflammatory load
Even small daily exposures can subtly tax the body’s detoxification systems, making it harder to maintain balance, energy, and resilience over time.
How to Prioritize What to Buy Organic
Buying 100% organic isn’t always practical or affordable—but you can make strategic choices. The Environmental Working Group (EWG) releases its Dirty Dozen and Clean Fifteen lists every year to help guide consumers.
The Dirty Dozen includes produce like strawberries, spinach, grapes, apples, and bell peppers — foods with thinner skins and more pesticide exposure.
The Clean Fifteen includes thicker-skinned items like avocados, mangoes, and melons that tend to have fewer residues.
Focus on buying the Dirty Dozen organic whenever possible, and save money by purchasing conventional versions of the Clean Fifteen.

Why Quality Animal Products Matter
When it comes to meat, eggs, and dairy, choosing organic, grass-fed, or pasture-raised isn’t just about ethics or taste—it’s about nutrition and chemical exposure. Pesticides and herbicides can accumulate in animal fat, and industrial farming practices often rely on antibiotics, growth hormones, and grain feed grown with chemical inputs. Organic and pasture-raised systems produce cleaner, more nutrient-rich foods that better support the body’s natural healing and anti-inflammatory processes.
Below are the key differences and benefits across various animal products:
Grass-Fed and Pasture-Raised Beef
Beef from grass-fed and pasture-raised cattle is far richer in omega-3 fatty acids, conjugated linoleic acid (CLA), and antioxidants like vitamin E and beta-carotene than conventionally grain-fed beef.
Omega-3s support heart, brain, and joint health while reducing inflammation.
CLA may help improve metabolic function and immune resilience.
The absence of synthetic hormones and antibiotics reduces toxic load and supports gut and endocrine health.
Grass-fed beef also tends to have a cleaner, more natural flavor and texture due to its varied diet and healthier fat profile.
Organic Poultry and Pasture-Raised Eggs
Chickens raised on pasture have access to sunlight, insects, and forage, resulting in eggs and meat that are higher in vitamins A, D, and E, as well as omega-3s and beta-carotene.
Pasture-raised eggs often contain up to twice the vitamin D of conventional eggs, an essential nutrient for mood, bone health, and immune balance.
Organic poultry avoids antibiotic and GMO feed exposure, making it a much cleaner source of protein and healthy fats.
Eggs, in particular, are one of the most concentrated sources of choline—a nutrient crucial for brain and nervous system health.
Organic and Grass-Fed Dairy: Milk, Butter, and Cheese
Organic and grass-fed dairy products come from cows that graze naturally, producing milk with significantly higher levels of omega-3 fats, CLA, and fat-soluble vitamins like A, D, and K2.
Grass-fed butter is an excellent source of butyrate, a short-chain fatty acid that supports gut lining integrity and reduces inflammation.
Organic milk and cheese contain fewer pesticide residues and no synthetic growth hormones (like rBGH or rBST).
The richer yellow color of grass-fed dairy is a visible indicator of its carotenoid and nutrient density.
Choosing organic full-fat dairy also ensures you’re getting the beneficial fats that help your body absorb fat-soluble vitamins effectively.
Why It’s Worth the Investment
While organic and pasture-raised animal products are often more expensive, their nutritional density, safety, and more humane sourcing make them worth prioritizing. You can balance costs by buying smaller portions, using bones for broth, or shopping local farmers’ markets and discount grocers in North County San Diego, where prices for grass-fed and organic meats are often lower than major chains. Buying more humanely raised animal products is also a powerful way to support more ethical food systems and industries.
Supporting Your Health and the Planet
Choosing organic isn’t just a personal health decision—it’s an ecological one. Organic farming avoids synthetic fertilizers and harmful chemicals that damage soil microbiomes, waterways, and pollinator populations. By supporting organic growers and ranchers, you’re investing in a more sustainable food system that nourishes both people and planet.
Bringing It All Together
You don’t need to transform your entire diet overnight. Start with small, intentional changes—choose organic oats instead of conventional, grass-fed butter instead of standard dairy, or locally grown organic produce when it’s in season. Over time, these simple swaps add up, supporting both your health and the broader food ecosystem.
It also helps to think in terms of stratified risk—prioritizing which foods matter most to buy organic or higher quality. For instance, chemical residues tend to bioaccumulate in animal fat, meaning toxins concentrate up the food chain and bind to fatty tissues. This makes exposure from conventionally raised animal products potentially more persistent in the body than residues found on most produce, which are typically more water-soluble and eliminated more readily.
For that reason, I personally consider organic and grass-fed butter, cheese, yogurt, and meats to be non-negotiables. They not only reduce long-term chemical exposure but also tend to come from more humane and ecologically responsible farming systems—making them a higher-value investment when working within a budget.
