Even a science based professional finds their head spinning with all the contradictory information about dietary fats.
Recently another study was published disputing years of recommendations to keep our total fat consumption to less than 30% and saturated-fat to less than 10% of our calorie intake. Although this particular study I am referring to was not the ideal way to measure the effect of dietary fat on cardiac mortality (i.e. death), it helps put things in perspective. Rather than demonizing one specific macronutrient, be it carbohydrate, fat, or protein, we should focus on eating whole food. When we consume whole food we naturally eliminate processed foods with little nutritional value. Perhaps this is another lesson to teach us that it is far better to focus on real food rather than individual nutrients. When you eat a balance of real food there is no need to count carbohydrates, protein or fat because you naturally get what you need.
Bottom line, consume whole foods such as meat, fish, eggs, dairy products, nuts and seeds, vegetables and fruits and whole grains; and limit (or avoid) consumption of processed foods. You don’t need a science background to understand that.
