We tend to forget where these traditions come from. I went to Sunday school as a kid, but had little to do with religion since then. These days most of us have more than enough to eat. It is so tempting to over-indulge. There are so many different diets people recommend it's hard to know what the best course is. I just try to eat fairly healthily and not worry about it too much. I gave up meat about 30 years ago.
Hope you are well.
