Study shows egg yolks are actually good for you

I have an update for anyone who is not yet convinced that it is time to add whole eggs back into their usual food intake. And as an added treat, another surprising health benefit of dark chocolate.

When will everyone learn to love the yolk? It is so nutrient rich. The yolk contains vitamins A, D, E and K, as well as omega 3 fatty acids. And the lutein and zeaxanthin in the yolk contributes to eye and brain health. And as for calories, one egg yolk has only about 50 calories. Weigh that against the benefit of all those nutrients and it is a calorie bargain.

A recent study in The American Journal of Clinical Nutrition reported on over 100 people with either prediabetes or type 2 diabetes. These subjects were counseled on a weight loss diet that included two eggs for breakfast six days a week. They were compared to a group not eating eggs. At the end of the three-month study period, the high egg diet produced no negative outcomes for cardiovascular risk. This includes total cholesterol, LDL cholesterol, triglycerides or inflammatory markers. Bring back the yolk.

After having had five eye surgeries and poor eyesight all my life, I am laser focused on eye research. This study from JAMA Ophthalmology made me happy.

Thirty participants were given about 1 1/3 ounces of either milk chocolate or dark chocolate. After testing it was found that visual acuity was improved after eating the dark chocolate when compared to the milk. The dark chocolate was 72 percent cacao. The researchers could not specify the mechanism for the improvement or if it would last beyond two hours. A possible explanation is that dark chocolate is rich in flavanols that support the production of nitric oxide which helps to relax blood vessels and improve blood flow. This is interesting, not a new treatment option for vision problems, but does give more reason to choose dark chocolate for a treat.
