We are baffled that certain oils are presented as “health” foods. Olive oil is not a health food. Neither is coconut, grape seed, flaxseed, or any other oil you’ve heard you must endeavor to add to your diet because it’s good for you. Sure, if you replace some or all of the butter in your diet with vegetable oil, you may do a little bit better, but that’s not at all the same as doing well. Oil is a bad idea because it is highly refined and its nutritional package is inadequate.
How is it that we know that processed sugars are junk foods, yet we’ve allowed ourselves to be convinced that certain oils are somehow good for us? Oil follows essentially the same model as processed sugar, which is also pressed from plants. Think about what oil is: fat—and nothing but fat. All the nutrients, including protein, carbohydrates, vitamins, minerals, fiber, and water, have been thrown away. Oil of any kind has more calories per gram than any other food we know. And without any fiber or water in it, oil lacks the bulk to convey to your senses how many calories you have eaten; this virtually guarantees you will consume more calories at the meal than you need. So we ask you: Why would you waste calories on something that has no nutrients in it other than fat? And why would anyone believe that highly concentrated fat is healthy?
In conclusion, highly processed foods are whole foods that have been refined and that generally lack proper nutrition.
