All over the world, people are getting sicker by the year, while food manufacturers, government bodies, and the mainstream medical profession keep telling us to eat more low-fat-high-carb foods and plenty of unsaturated golden oils. They warn us to stay away from all the “dangerous” saturated fats and oils. So we go on buying convenience foods riddled with carbs and sugars, believing that we are doing the right thing to protect from heart disease, cancer, diabetes, and mounting degenerative diseases that plague the Western World. Well, my friend, such advice from the powers-that-be is not just untrue—it is positively dangerous.

To stay healthy, protect yourself from obesity, degenerative conditions, and early aging, it’s important that you avoid starchy carbs, hidden sugars, and all highly processed unsaturated oils. We have been indoctrinated with an irrational fear of fat because of inaccurate research carried out way back in the 1960s when absurd assumptions became turned into quasi-religious non-sense dogma. Since then, instead of protecting us from heart disease, obesity, and other degenerative conditions, what we’ve been told has made us highly susceptible to all these diseases. It’s time to get savvy about the fats—to learn which fats are life-destroying and which are health-enhancing and to change the way you eat.

Here’s the truth: Polyunsaturated fats and oils turn rancid when heated. They turn into a health-destroying source of free radicals that do your body great harm. They attack cells and damage DNA. Recent, reliable scientific studies show a definite connection between consumption of these polyunsaturated oils and the development of cancer, as well as heart disease and many other illnesses. Here’s the gen: avoid these oils at all cost: Safflower, Corn, Sunflower, Soybean and Cottonseed. They are badly processed, and are often full of dangerous chemicals. As far as canola oil is concerned—commonly used in the manufacture of convenience foods—it turns rancid quickly and is associated with the development of fibrotic heart lesions.

The oils and fats you want to eat to look after your health and to stay lean are these: butter from grass-fed animals, and tropical oils such as coconut oil. Coconut oil is great for cooking. Extra-virgin olive oil is ideal for salad dressings. These are quality fats which, eaten on their own, or together with protein but without an abundance of starchy carbohydrates and sugar alleviate hunger and act as a great source of energy throughout the day. Eating too little of these good fats can lead to an experience of sitting down to a meal and, no matter how much you eat, still craving more food at the end of it. These natural fats let you know when your body is satisfied. They also help balance your hormones while significantly enhancing how you look and feel.

Low-fat foods fill our supermarket shelves, attracting ignorant consumers trying to be good and eat what they’ve been told to eat. Manufactured convenience foods have become a roaring financial success story for food manufacturers. So people eat low-fat foods, believing that these are good for them, without realizing that manufacturers, in preparing low-fat menus, have replaced fat with sugar in their wares. We have been told the false notion that all saturated fats are dangerous.

Back to the good oils: Olive oil is a monounsaturated fat and one of the safest vegetable oils you can use. It is well suited to dressings and can be heated, but only to moderate temperatures. Make sure that the Extra Virgin Olive Oil you buy is cloudy (not filtered) and a golden-yellow color. Coconut oil is your safest, healthiest choice for cooking since it remains stable, even at high temperatures. It also boasts antiviral and antibacterial properties. The other good, and often forgotten, saturated fat is butter but only from cows who have been grazed on green grass for at least part of their life.
