I followed some advice by @amber and tested breaking my fast with beef broth, followed by a bit of beef meat. I first had a cup of broth. I waited for about half hour and then ate some more beef broth with pieces of beef in it. It worked beautifully! I do a lot of multi day fasting, and a lot of experimentation with breaking fasts with different foods, and I must say, Amber was bang on. It was my best experience breaking the fast.
Amber’s reason for suggesting broth and beef was because this is a food that has the least (statistically) reputation for food sensitivities.
So, a good rule of thumb is when breaking your fast, avoid foods that tend to have a reputation for allergies or sensitivities (like eggs, cheese, nuts, etc…). Since your digestive system is cleaned out, any slight sensitivity you may have (which would be otherwise be masked or diluted by other foods in your gut) can be enhanced by multi fold.
