Adding a hard boiled egg to your next salad diet might be a good idea. Dr. Wayne Campbell who led a research team at Purdue University found that eating salad with eggs improves nutrient absorption. The eggs improves our absorption of carotenoids in vegetables. The health benefits of carotenoids are:
- reduce inflammation and oxidative stress
- cancer prevention
- protection from heart disease
- source of vitamin A
It is recommended to have salad consisted of five colours of raw vegetables, which are red, purple, orange/yellow, green and brown/white. You may get some ideas of what vegetables to use for your salad recipe from here and here. The study was published in the American Journal of Clinical Nutrition.
