They brainwashed you and convinced you that fat is bad. Your grandfather, your great-grandfather ate pork in a good way. They fried the lard in a good way, and even then they were much healthier than you, even eating a lot of fat.
And why? Because all cell membranes are made of fat. Our brain is made of fat. If you take the fat out of your life you have a stroke and become cognitively impaired. There is a disease in the world today called lipid deficiency. Cardiologists scare people that they can not eat fat because if they eat fat, cholesterol will rise. But the truth is that cholesterol is not made from fat, cholesterol is made from carbohydrate. Cholesterol is not a fat, it's an alcohol. If your cholesterol is high, it is probably because you are eating a lot of sugar. If you lower your intake of sugar, it will also lower your cholesterol.
And many times your cholesterol is high because you have a thyroid problem, or hypothyroidism. In fact, in the past, high cholesterol levels were used as an indication of a possible thyroid problem. It was the "poor test" to know if thyroid problem existed. So if you go to your cardiologist and he analyzes your cholesterol and passes you a statin without seeing if you have thyroid problem, in fact it did not solve your problem. Imagine you have a fireworks factory and you have a smoke detection alarm. Then the alarm rings and you cut his wire so he stops ringing. It is the same thing to want to just lower the cholesterol without knowing why it is high, the root cause of it.
Eating nonfat food is like eating styrofoam, no one can take it. Then you end up putting sugar to improve the flavor. That is, diets low in fats make you unconsciously ingest more carbohydrates; And in eating more carbohydrates you develop a metabolic syndrome. You take beer belly and you start having problems like diabetes.
So what are the real causes of high colesterol?
overeating;
eating too much processed foods;
eating too much sugar;
eating too much bad fats like trans/saturated fats;
eating too little fiber;
eating too much omega 6 fatty acids in proportion to omega 3;
drinking too much alcohol.
