Alas, decades' worth of research utterly failed to demonstrate this correlation, and the 2015-2020 Dietary Guidelines for Americans1,2,3,4,5 finally addressed this scientific shortcoming, announcing "cholesterol is not considered a nutrient of concern for overconsumption."6
This is good news, since dietary cholesterol plays an important role in brain health and memory formation, and is indispensable for the building of cells and the production of stress and sex hormones, as well as vitamin D. (When sunlight strikes your bare skin, the cholesterol in your skin is converted into vitamin D.)
Unfortunately, the dietary guidelines still cling to outdated misinformation about saturated fat, wrongly accusing it of raising LDL and contributing to heart disease. Here, science has shown that saturated fat only raises the safe, fluffy LDL particles. It also increases HDL, which is beneficial for your heart.
The guidelines became and are still confusing because the basic premise was wrong. Dietary fat is indeed associated with heart disease, but it's the processed vegetable oils, which are loaded with trans fats and oxidized omega-6 fats, that are the problem, not saturated fats.
The introduction of industrialized, highly processed and frequently heated omega-6 vegetable oils distorted the vitally important omega 6-to-3 ratio, causing metabolic catastrophes. The problem was further exacerbated by replacing saturated fat with refined carbohydrates, which were incorrectly viewed as a healthier option, thanks to misinformation created and spread by the sugar industry.
Impairs Electrical Storage Potential of Your Cells
Nutrition and biochemistry are clearly important to your health, but so is your body's electrical system. All our membranes are made of fats that are insulators and connected through a conductor. This arrangement sets up a biological capacitor to store electrons — but only if the fats are healthy.
If you consume damaged fats, or worse, heated and hydrogenated oils, the fatty acids in the cell membrane essentially become nonfunctional and unable to store body voltage, thus increasing the risk for disease. This is one of many reasons why it is so vital to eat healthy fats.
