Many of you may have heard that one should not eat too many eggs or remove the yolk as it raises cholesterol, but cholesterol isn’t as simple as we think and while a typical egg yolk has 186 mg of cholesterol (62% RDA) eating 3 eggs a day is completely safe.
Cholesterol is not completely bad for health and is required for healthy body function.
Cholesterol levels are regulated by our liver in conjunction with our diet (!!!!)
Egg yolks are rich source of vital nutrients such as vitamins, selenium, folate, phosphorous, zinc and calcium.
Studies have shown no substantial link between eating eggs regularly and increased CVD risk.
Help you feel full for longer, thus aiding in weight loss.
Source of good quality protein.
Help keep eyes and brain healthy.
The takeaway box:
In 1961 American Heart Association published guidelines to reduce amount of cholesterol intake which resulted in negative PR of eggs, certain types of meats and dairy products. For a while we have been conditioned to believe that eating too many eggs can increase risk of heart disease due to their cholesterol content but recent studies have found that having 3 eggs a day is safe. Although, 30% of the population known as hyperresonders do experience an increase in LDL (bad) cholesterol but the type of LDL increased does not promote CVD risk. On the contrary, some studies even conclude that egg consumption increases HDL (good) cholesterol. Another myth that a lot of people believe is that brown eggs are better than white ones, the truth is that difference in colors and sizes are due to breed of hens and but all eggs are nutritionally quite similar. If you want to buy healthier options then go for eggs which are omega-3 enriched (through hen’s diet) and laid by free-range hens. My personal recommendation is to limit egg intake if you already have high cholesterol and triglyceride issues.
PS, I've listed enough references to strengthen the case :D
