Why were they a no-go? Eggs are another food source that have been eaten for thousands of years yet suddenly got a bad rep when they were linked to heart attacks and strokes. It was then recommended that you eat no more than four a week. Why they were wrong: Before the big cholesterol scare, eggs were a daily staple of many diets and without them, finding cheap and reliable sources of protein became much harder. Thankfully a couple of years ago, various studies proved that eggs can actually increase HDL (our good cholesterol) plus, they contain zeaxanthin and lutein which are important for eye health. Eggs are also relatively low in calories with a large egg containing around 77 cals whilst being packed full of protein, amino acids, vitamins and minerals making them an excellent breakfast or lunch option.
