Embracing an Oil-Free Lifestyle: Health Benefits and Considerations

At Nature’s pHarmacy® we say no to seed oils (edible oils). The “edible” oils of today can no longer be considered edible. They contain too many nutrient-free calories, contain toxins and microplastics, provide too many omega-6 oils that promote inflammation, and affect the digestive microbiome. Most importantly, edible oils are not needed in your diet; whole nuts and seeds contain plenty of healthier, protected fats with nutrients to help you.

In recent years, the trend towards oil-free eating has gained momentum within the wellness community. As more people become aware of the potential health risks associated with various edible oils, many are choosing to adopt an oil-free lifestyle. From concerns about chemical residues in processed oils to the nutritional benefits of whole foods, this shift reflects a growing desire for cleaner, more mindful eating habits.

This article will review some of the specific issues with today’s processed oils, and discuss health benefits of, and specific recommendations for, adopting an oil-free lifestyle.

The Case Against Edible Oils

Here are some of the specific issues associated with various commonly used oils. Some are purposely adulterated, but many have toxins, chemicals, and adulterants that are accidentally introduced into the oil at the time of harvest, processing, or bottling. Let’s take a look at some of the main culprits.

EVOO (Extra Virgin Olive Oil) Adulteration: The adulteration of olive oil, particularly extra virgin olive oil (EVOO), is well known. A recent article in Forbes notes that 80% of more of all Italian olive oil is “neither Italian nor virgin.”  In regions known for olive oil production, such as Spain, Italy, and Greece, some producers have been found to mix lower-grade oils with EVOO to increase profits. This practice can dilute the quality and nutritional benefits of the oil while misleading consumers who believe they are purchasing high-quality products. While TRUE EVOO has been touted for its 20+ types of polyphenols, which are plant-based antioxidants that help reduce inflammation and protect the heart, the adulterated oils may lack the antioxidants and healthy fats that genuine EVOO provides. Actual EVOO is viscous, aromatic, green, and uplifts your spirit upon smelling. It is important in the local mediterranean diets. However, not enough of this is produced to be available commercially.

Microplastic Contamination: A research article printed earlier this summer found that ALL samples of EVOO, olive oil, sunflower oil, and mixed seed oil from Italy and Spain contained microplastic contamination, and there was no difference in whether the oils were packaged in plastic or in glass containers. Microplastics can negatively affect the “digestive, respiratory, endocrine, reproductive, and immune systems.”  Read more about microplastics and how they negatively affect the body in our previous blog post.

Omega-6 Fats: Omega 6 fats play a role in inflammation, which is part of the body’s natural immune response. However, excessive omega-6 intake, especially without a balance of omega-3 fats, can lead to chronic inflammation. Chronic inflammation is linked to several health issues, including heart disease, arthritis, diabetes, and even some cancers. Historically, humans consumed omega-6 (pro-inflammatory) and omega-3 (anti-inflammatory) fats in nearly equal amounts. Today, with the widespread use of refined oils, the average diet is skewed towards far more omega-6 than omega-3 fats—some estimates suggest a ratio as high as 20:1 or more. Oils highest in omega-6 fatty acids include: soybean, corn, safflower, sunflower, cottonseed, grapeseed, peanut, sesame, and rice brain oils. They are frequently used in processed foods, fast foods, and for frying because they are inexpensive and have long shelf lives.

Chlorophyll in Edible Oils: The addition of chlorophyll to oils is a controversial practice intended to enhance color and appeal. While chlorophyll is generally recognized as safe, its inclusion can pose concerns. Chlorophyll is sensitive to light and can lead to the oxidation of oils when exposed, potentially reducing their shelf life and creating harmful compounds such as free radicals and peroxides. This oxidation could counteract any health benefits of adding chlorophyll, making the oil unstable for long-term storage. Additionally, the sources of chlorophyll used for extraction may vary, and synthetic or lower-quality sources could introduce unwanted additives or impurities.

Hexane in Oils: Many oils, especially those derived from soybeans, corn, and sunflower seeds, undergo an extraction process that utilizes hexane, a petroleum byproduct. Although much of the hexane is removed during refining, trace amounts may linger in the final product. The long-term effects of consuming these residues are still not well understood, prompting many health-conscious consumers to seek oils extracted without chemical solvents.

Erucic Acid in Canola Oil: While modern canola oil is bred to have low levels of erucic acid, concerns remain regarding its potential health effects. High levels of this fatty acid have been linked to heart issues in animal studies. Given that canola oil is often present in processed foods, consumers may unknowingly consume it regularly.

Gossypol and Sterculic Acid in Cottonseed Oil: Cottonseed oil, derived from the seeds of cotton plants, can contain gossypol and sterculic acid, naturally occurring toxins. Glossypol is an antinutrient that can suppress immune system function, affect fertility, and cause liver, kidney, and heart toxicity. Sterculic acid is a cyclopropane fatty acid (CPFA) that can interfere with fat metabolism and cause liver and reproductive toxicity. Although refining processes remove much of the gossypol and sterculic acid from cottonseed oil, there may still be trace amounts present, raising concerns about impacts on health.

Biocide Contamination: During the cultivation of oilseeds, farmers may use a variety of biocides, including pesticides, fungicides, herbicides, and insecticides, to protect the crops from pests, diseases, and weeds. These chemicals are intended to degrade or be washed off before processing, but trace amounts of residue may remain on the seeds and enter the oil extraction process. While levels may be low and considered within regulatory limits, there is concern about the cumulative effects of long-term exposure to these chemicals, including endocrine disruption and cancer risk. While choosing organic and non GMO oils can help reduce risk of biocide residue, there can be “drift” from nearby farms, and unintended contamination from wind, water runoff, and soil erosion. While organic oils are less likely to contain harmful synthetic biocides, they are not guaranteed to be 100% free of all residues. 

The Health Benefits of Going Oil-Free

Adopting an oil-free diet can lead to numerous health benefits, making it an attractive option for those looking to improve their overall well-being. Here are some key advantages:

Increased Nutritional Intake: By focusing on whole foods and eliminating oils, individuals often increase their consumption of fruits, vegetables, grasses, legumes, and nuts. These foods are rich in vitamins, minerals, and fiber, providing essential nutrients without the empty calories found in oils.

Weight Management: Oils are calorie-dense, and cutting them from your diet can help reduce overall calorie intake. This reduction can support weight management goals and may promote a healthier body composition.

Enhanced Absorption of Healthy Fats: While it may seem counterintuitive, avoiding oils can lead to better absorption of healthy fats from whole food sources. Foods like avocados, nuts, and seeds provide monounsaturated and polyunsaturated fats, which are beneficial for heart health and overall wellness.

Improved Digestion: An oil-free diet can contribute to better digestion. Oils can slow down digestion and create a feeling of heaviness in the stomach. By eliminating oils, many people report improved gastrointestinal comfort and regularity. Additionally, whole foods high in fiber promote a healthy gut microbiome, supporting digestion and nutrient absorption.

Minimized Inflammation: Processed oils, particularly those high in omega-6 fatty acids, can contribute to inflammation in the body when consumed in excess. By removing processed oils from the diet, individuals may help reduce their intake of inflammatory compounds, potentially leading to better Omega-3/Omega-6 balance, decreased chronic inflammation, and a lower risk of related health issues, such as heart disease and arthritis.

Practical Tips for an Oil-Free Lifestyle

Transitioning to an oil-free lifestyle doesn’t have to be overwhelming. Here are some practical tips to help you embrace this approach while still enjoying delicious and satisfying meals:

Explore Cooking Methods: Instead of sautéing or frying, try steaming, boiling, baking, or grilling your foods. These methods preserve flavor and nutrients without the need for added oils. The recipes we provide in our weekly Nature’s pHarmacy blog are typically oil-free. There are many simple recipes there that you can try as you work to eliminate processed oils from your diet.

Use Water or Broth for Sautéing: When cooking vegetables or aromatics, use water or low-sodium vegetable broth instead of oil. This method allows you to achieve a similar texture and flavor while keeping your dish oil-free.

Embrace Whole Foods: Focus on whole, minimally processed foods that provide natural flavors and textures. Incorporate a variety of fruits, vegetables, grasses (e.g., quinoa, wild rice), legumes, nuts, and seeds into your meals to ensure balanced nutrition.

Experiment with Flavor: Use herbs, spices, citrus (preferably lime) juice, and vinegar to add flavor to your dishes without oil. Fresh herbs like basil, cilantro, and parsley can elevate the taste of salads, soups, and roasted vegetables.

Choose Healthy Fats Wisely: While the goal is to eliminate oils, it’s important to include healthy fats from whole food sources. Avocados, nuts, and seeds can provide essential fatty acids without the downsides associated with processed oils. Walnuts contain omega-3 fatty acids, as do flax and chia seeds, and some cold water fish like salmon.

Read Labels: Become a label detective! Many packaged foods contain hidden oils, even in products labeled as “healthy.” Look for oil-free options or make your own versions of favorite condiments and dressings.

Plan Ahead: Meal prep can make it easier to stick to an oil-free lifestyle. Prepare your meals in advance, and keep oil-free snacks on hand, such as fresh fruits, vegetables, or homemade energy bars or bites. Check out our Chocolate-Coconut Energy Bites or our Carrot-Pecan Bites.
