The Truth about Eggs and Cholesterol!
When I speak to people about what I eat (notice im not calling it a diet!) they are really surprised about how many eggs I eat a day/week. Then I get the "Oh that's really bad for your cholesterol".
So many people still believe that eating egg yolks is literally a recipe for high cholesterol, this is NOT the case.
What is Cholesterol?
Cholesterol is a fatty substance found in your blood. If you have too much cholesterol in your blood, it can increase your risk of cardiovascular disease. It is important to note that there are 2 different type of Cholesterol:
- Low-density lipoproteins (LDL) is known as the bad type of cholesterol. LDL carry cholesterol from your liver to the cells that need it.
- High-density lipoprotein (HDL) is known as the good type of cholesterol. HDL carry cholesterol away from the cells and back to the liver to be broken down.
Dietary Cholesterol & Bloodstream Cholesterol
It would make logical sense that if you want to decrease the amount of cholesterol in your blood then you should cut the amount of cholesterol that you eat. This is why eggs (particularly egg yolks) have a bed rep (they contain approx 200 mg per serving).
The thing is ingested cholesterol doesn't raise blood cholesterol as much as you may think.In fact, only 30% of people experience significant increases in cholesterol levels after following a diet high in cholesterol.
A study conducted by Harvard that looked at the dietary habits of more than 100,000 people concluded that daily egg consumption in healthy individuals didn’t increase risk of coronary heart disease. In another study by the University of Connecticut found that eating three eggs per day as part of a low carbohydrate regimen improved HDL -- the "good" cholesterol -- with NO negative health effects.
Its more about Carbohydrate levels!
Researchers found that “carbohydrates, rather than fat, plays a critical role in activating pro-inflammatory processes through their effect on the fatty acid composition of lipids and membranes.”
By restricting carbohydrate intake and replacing it with protein and fat, studies show it is possible to lose fat, decrease inflammation, and by eating eggs, you can improve cholesterol too.
A study in the journal Nutrition and Metabolism compared the effect of two carbohydrate restricted diets in overweight men—both diets included 18 percent carbs, 26 percent protein, and 56 percent fat, but one group ate three eggs a day.
- After 12 weeks, the group that ate eggs actually lost slightly more total body fat and saw a decrease in levels of inflammation (significantly more than the group that didn’t eat eggs)
- The egg group also increased their “good” HDL cholesterol levels
- The group that didn’t eat eggs had no change in cholesterol at all.
- The group that ate eggs also experienced better insulin sensitivity and higher levels of adiponectin, which is a hormone involved in fat burning that also decreases inflammation.
For me the benefits of eating eggs far outweigh any negative press associated with them.
