Abandoning Traditional Fats for Processed Vegetable Oils Has Led to Declining Health

11 Charts That Show Everything Wrong with Our Modern Diet

by Dr. Mercola

Three decades ago, the food available was mostly fresh and grown locally. Today, the majority of foods served, whether at home, in school or in restaurants, are highly processed foods, filled with sugars, harmful processed fats, and chemical additives.

During that same time, obesity rates have skyrocketed, and one in five American deaths are now associated with obesity. Obesity-related deaths include those from type 2 diabetes, hypertension, heart disease, liver disease, cancer, dementia, and depression, as nearly all have metabolic dysfunction as a common underlying factor.

Abandoning Traditional Fats for Processed Vegetable Oils Has Led to Declining Health

Fats help your body absorb important vitamins, including vitamins A, D, and E, and fats are especially important for infants and toddlers for proper growth and development. Moreover, when your body burns non-vegetable carbohydrates like grains and sugars, powerful adverse hormonal changes typically occur. These detrimental changes do not occur when you consume healthy fats or fibrous vegetables.

As explained by Dr. Robert Lustig, fructose in particular is “isocaloric but not isometabolic,” which means you can have the same amount of calories from fructose or glucose, fructose and protein, or fructose and fat, but the metabolic effect will be entirely different despite the identical calorie count. Furthermore, saturated fats, although supplying more calories, will NOT actually cause you to get fat, nor will it promote heart disease.

Unfortunately, the healthiest fats, including animal fats and coconut oil, both of which are saturated, have been long portrayed as a heart attack waiting to happen. Meanwhile, harmful hydrogenated vegetable oils such as corn and canola oil have been touted as “healthful” alternatives. Ditto for margarine.

Boy, did they get this wrong. Nothing could have been further from the truth. The hydrogenation process creates incredibly harmful trans fats, which the US Food and Drug Administration is now finally considering banning altogether. (I’ll review the health hazards of trans fats in further detail below.) Clearly, switching from lard and grass-fed butter—which contains heart-protective nutrients—to margarine and other trans-fat rich hydrogenated oils was a public health experiment that has not ended well.

Low-Fat Fad Has Done Unfathomable Harm

Conventional recommendations have also called for dramatically decreasing the overall amount of fat in your diet, and this fat aversion is yet another driving factor of metabolic disease and chronic ill health. As I and other nutritional experts have warned, most people (especially if you’re insulin or leptin resistant, which encompasses about 80 percent of Americans) probably need upwards of 50-85 percent of daily calories from healthful fats. This is a FAR cry from the less than 10 percent of calories from saturated fats recommended by the US Department of Agriculture.³ As stated in the featured article:

“The first dietary guidelines for Americans were published in the year 1977, almost at the exact same time the obesity epidemic started. Of course, this doesn’t prove anything (correlation does not equal causation), but it makes sense that this could be more
