- lowering the cholesterol can reduce the risk of heart attacks, although the data are not all that significant. -How do you reduce your cholesterol? - blood tests that can measure cholesterol levels very, very accurately. 2: -blood cholesterol also is a function of some of the dietary fats that we eat. - dietary fats have an effect on the LDL receptors. -affect the LDL receptor activity, -The egg yolk does contain cholesterol. -studies actually do not corroborate that. - turns out that while there are some people who are sensitive to dietary cholesterol, the vast majority of the population is not. -there’s no association between egg intake and heart disease. -Most of the population shows no change in blood cholesterol with egg consumption.
-if you take out some of the so-called cholesterol-rich foods like lobster, or shrimp, et cetera, they actually contain less cholesterol than the eggs. -Trans fats are really byproducts of the process of hydrogenation. -the process that was originally used to make margarine. — margarine, what they did was to take some liquid oils and add hydrogen gas to it to harden them. And as a byproduct, produced trans fats. -theory is that saturated fats raise cholesterol. - cholesterol in fact then increases your risk of heart disease. -so reducing saturated fats reduces the risk. - has never been proven, as you will see. -some foods that are basically monounsaturated fats, like olive oil, may have other components that are healthy. -polyunsaturated fats also fall into two distinct categories. 1. There are the omega-3 fats 2. the omega-6 fats. - the omega-3 fats are kind of good for us, whereas the omega-6 are more questionable because they have inflammatory properties. - no significant evidence that saturated fats increase the risk of heart disease. -Saturated fat intake in this particular study, as you can see, inversely associated with the incidence of stroke in Japan. -more saturated fat people consumed, the lower the incidence of stroke. -no difference in coronary heart disease rates based upon diets. -The commonly held belief that the best diet for prevention of coronary heart disease is a low saturated fat, low cholesterol diet is not supported by the available evidence from clinical trials. —————————————————- 3: -paper headline that "Saturated Fat's Role in Heart Disease Is a Myth." - very controversial. -the researchers claimed that if palm oil was decreased in consumption in India, where it forms a large part of the diet, it would have a very, very significant impact on heart disease. - French paradox, where you take a look at the 50 million Frenchmen, who eat all of those croissants, and high fat cheeses, and stuff their geese, and eat their fatty livers. -have high cholesterol levels, higher than us. -have a lower incidence of heart disease. -usual explanation to the French paradox is the red wine. -red wine ingredient called resveratrol reduces their risk of heart disease.
