We are going to veer away from the original format and talk about something in detail that comes up ALL the time when I talk about the Ketogenic way of eating. Cholesterol. The mere mention of the word makes cardiologists cringe and dollar signs roll across the eyes of statin manufacturers. Diet, exercise and medication are prescribed as a the cure all to preventing heart attacks and strokes. While I don’t assume to offer medical advice and any dietary changes should be discussed with your doctor I DO ascertain that for years you’ve been told the WRONG way to eat.
From the National Heart, Lung and Blood Institute (http://www.nhlbi.nih.gov/health/health-topics/topics/hbc):
“Your body needs some cholesterol to make hormones, vitamin D, and substances that help you digest foods. Your body makes all the cholesterol it needs. However, cholesterol also is found in some of the foods you eat. Cholesterol travels through your bloodstream in small packages called lipoproteins (lip-o-PRO-teens). These packages are made of fat (lipid) on the inside and proteins on the outside. Two kinds of lipoproteins carry cholesterol throughout your body: low-density lipoproteins (LDL) and high-density lipoproteins (HDL). Having healthy levels of both types of lipoproteins is important. LDL cholesterol sometimes is called “bad” cholesterol. A high LDL level leads to a buildup of cholesterol in your arteries. (Arteries are blood vessels that carry blood from your heart to your body.) HDL cholesterol sometimes is called “good” cholesterol. This is because it carries cholesterol from other parts of your body back to your liver. Your liver removes the cholesterol from your body.”
Traditionally the American Heart Association has claimed that a low fat (and by consequence high carbohydrate) diet was the key to decreasing your LDL and raising your HDL. Recently the nation’s top nutrition advisory panel has decided to drop its caution about eating cholesterol-laden food, a move that could undo almost 40 years of government warnings about its consumption. Why? Because the science no longer adds up. They found that dietary cholesterol intake has little to no effect on HDL/LDL levels in patients following a Ketogenic diet. (Source: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2716748/) Further more a diet high in carbohydrates such as a low fat diet can increase overall triglyceride levels, which in combination with low HDL levels, is an increased risk factor for heart attack or stroke. (Source: https://my.americanheart.org/idc/groups/ahamah-public/@wcm/@sop/@smd/documents/downloadable/ucm_425988.pdf) The simple fact is the Ketogenic way of eating improves your HDL, lowers your LDL and decreases your triglycerides.
The logical conclusion? Cut out the carbohydrates and follow a Ketogenic way of eating. Your waist, your body and your overall sense of health will thank you! Until next time…
