My parents raised me on a strict vegetarian diet. They didn't allow me to eat eggs as they believed a potential life is killed in the process. I don't really hold the same views as them but since I was raised to not eat meat and eggs, I just find it very difficult to consume them as they just gross me out. I have tried to eat them in the past but was unable to do so. However, I think I can force myself to start eating eggs regularly.
I was raised Jewish, it took me a lot of effort to learn to eat pork and shrimp (very recently), and even meat with dairy (ten years ago), I understand you situation.
IMO eggs are a fabulously nutritious food source, particularly free-range omega-3 eggs. If you have no rational objections, you can figure out how to eat them.
In general though, as pointed out by Jason Fung, there are multiple ways to eat healthy. With only 2,500 calories a day there's no way you're getting all the so-called superfoods, so it's fine to avoid this or that great food.
Foods to avoid:
- Added sugars, including pure sugars like coca cola, candy, fruit juice, etc;
- Wheat especially white flour ... also unnecessary potato and/or corn;
- Low-fat dairy products;
- Vegetable oils, margarine;
- Processed meats;
- Animal products with steroids, antibiotics, etc;
- Possibly aspartame, not sure;
Even those have exceptions, for example wheat. Whole spud, stone ground aincorn wheat is probably far better.
