Here’s another reminder to make sure you get plenty of omega-3 fatty acids, from Cleveland Clinic Wellness. The clinic notes that in a study performed on animals, consuming more of the nutrient was linked to a lower rate of breast cancer tumors forming and spreading, compared against diets full of the omega-6 acids found in vegetable and seed oils. More on that:

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.

The clinic recommends making whole veggies, beans, and fruit the base of your diet, and getting in at least two servings of omega-3-rich fish every week, such as wild salmon or sardines.
