In a preliminary study on animals, a diet high in omega-3-fatty acids from fish oil was linked to a much lower incidence of tumors forming and spreading compared with a diet high in plant-derived omega-6 fatty acids. Both omega-3s and omega-6s are known as “essential fats,” meaning that our bodies can’t make them—you must get them from your diet. While you need both fats, the ratio you consume may affect your health. Unfortunately, the typical American diet includes too little omega-3s and an overdose (think 15 times the desired amount!) of omega-6s, mostly coming from the refined vegetable and seed oils in processed foods, packaged snacks, and fast food. That high ratio of omega-6s to omega-3s may contribute to chronic inflammation and a range of diseases, including breast cancer. Tweak your ratio by making whole plant foods like veggies, beans, and fruit (rather than packaged or fast food) the foundation of your diet, and enjoy at least two servings of omega-3-rich fish a week. For nourishing fats and low levels of mercury and other environmental contaminants, wild salmon salmon (get it frozen from September to May) or sardines are great choices.

“Omega 3 fatty acids are most important, as they bring balance to our hormones, reduce inflammation, regulate our blood sugar, prevent blood clotting, keep our cholesterol and triglycerides in balance, relax our blood vessels, and make our cells healthy and resilient.”
