But what are the bad fats?  Omega-6 fatty acids when out of balance with omega-3 fatty acids are pro-inflammatory, one of the primary factors for causing the runaway, chronic inflammatory process in most Americans.  To eliminate the imbalance of omega-6 to omega-3, we should increase omega-3 fatty acids and decrease omega-6 fatty acids.  Eating more cold water fish, grass fed beef and buffalo, range fed chickens and other foul, and eggs from range fed chickens.  Butter, cream and milk from range fed cows provide more omega-3 fatty acids than corn fed cattle and caged chickens.  Including a variety of nuts in our diet can provide healthy fats.  Almonds and walnuts provide many heart benefits.  Other healthy fats come from avocados and olives, olive oil, sesame seed oil and camelina oil, the new omega-3 fatty acid that I believe will soon replace flax seed oil.  Flax seed oil is highly unstable and remains fresh only for a few weeks, whereas camelina oil, because of its high content of tocopherols (vitamin E) and tocotrienols (super vitamin E), make it stable for up to two years without refrigeration.  Heart disease and cancer increased dramatically when we were falsely led to believe that animal fats were bad for us and the switch to vegetable fats increased heart disease and cancer.  Absolutely reduce, or avoid entirely, soybean oil, corn oil, canola oil, safflower seed oil, sunflower seed oil, peanut oil and anything made with or from these oils.  Studies have clearly shown that as unsaturation, meaning polyunsaturated of dietary oil increases, cancer rate increases, heart disease increases, mental skills and learning ability diminishes, and in fact, the entire body deteriorates from the onslaught of massive free radical damage and the ensuing inflammation.  The bottom line, eat more saturated fat for good health, butter, cream, lard, eggs, and lower vegetable fats, margarine, vegetable shortenings and food prepared from vegetable oils.
