According to the American Heart Association (AHA), there is no numerical recommendation of cholesterol intake from food, as the AHA finds no link between dietary cholesterol and cardiovascular risk. Although you have long heard that dietary cholesterol is generally not good for the cardiovascular health, you might be surprised to know the studies have shown no relationship between dietary cholesterol and cardiovascular disease.
Changing dietary recommendations
Based on this and other data, specific dietary cholesterol target recommendations were removed in recent guidelines. It has raised questions about the role of dietary cholesterol with respect to cardiovascular disease. This advisory was developed after a review of human studies on the relationship of dietary cholesterol with blood lipids, lipoproteins, and cardiovascular disease risk to address questions about the relevance of dietary cholesterol guidance for heart health. Evidence from observational studies conducted in several countries generally does not indicate a significant association with cardiovascular disease risk. Learn more...
Analysis: why our traditional understanding about dietary cholesterol was wrong
According to Prab R. Tumpati, MD, founder, WikiMD, and W8MD weight loss, sleep and medspa centers]], founder of W8MD medical weight loss, sleep and medspa and WikiMD, the discrepancy was likely due to the often missed fact that up to 70% of our entire bodies cholesterol is manufactured by the liver in our body from blood sugar and only about 30% comes from the diet.
Inflammation, not cholesterol is key
It is the inflammation that is the risk factor for cardiovascular disease, not as much from cholesterol. Unfortunately, the traditional dietary recommendations assumed that most of our cholesterol in the blood comes from the diet which is not the case. And worse yet, most of the traditional dietary recommendations such as the now withdrawn Food pyramid from the USDA did more harm than good by promoting low fat, low cholesterol but high starchy foods which in turn increased starch (sugar) in our diet, leading to a new problems such as insulin resistance and metabolic syndrome. Since insulin is the hormone that promotes liver production of cholesterol which is the 70% pathway for cholesterol production, strangely, the low cholesterol diet (read high starch diet) leads to what is called insulin resistance which in turn leads to higher insulin levels as a compensation.
This high insulin then causes excess cholesterol production in the liver thus the low fat, low cholesterol traditional food pyramid based diet indirectly contributed to high blood cholesterol, and higher inflammation (via increased belly fat that produces inflammatory cytokines) thus strangely increasing the risk of heart disease.
