Remember the late 80's and early 90's with the low fat, high carb everything? Entenmann's cakes, and every possible kind of food geared to keep your cholesterol down... I ingested my fair share, but then I started reading labels. The amount of sugar in these products was high, and I was shocked. I stopped eating them and began an odyssey towards a greater understanding of nutrition and what it can do to you.
We need cholesterol, and LDL (the "bad" cholesterol) helps to carry fats to our brains (which is about 70% fat). The killer is not the LDL, but the sugar that causes oxidation of the fats, to leave them hard and sticky, causing them to adhere to the arterial walls, leading to atherosclerosis. There is no scientific evidence that ingesting fats leads to this, and on the contrary, high cholesterol correlates with a longer lifespan.
What's more, we were told that vegetable oils were better than butter, and that eggs were bad. WRONG! Hydrogenated oils lead to cancer and most of them are GMO. Even cooking olive oil is questionable, as when heated it becomes a trans fat. Do yourself a favor and use coconut oil for everything, unless you are making salad dressing, when cold-pressed virgin olive oil should be your go to.
