It's not very good, especially the processed type red meat. However, small amounts of beef - like 50-100 grams once in a few weeks or months (from home grown cows) is not bad for a healthy person (just my opinion, if your conscience says otherwise, don't listen to me). However, other types of red meat can be really dangerous (beef also if binge eaten): the European and possibly Australian type of sheep are very fat and hard to digest by the stomach, deer can be hard also for stomach but of course few people afford to eat a lot of that anyway. It's good to have your blood tests done yearly, so you know if you have anemia or avitaminosis. The vegetarian diet is the best as a rule, but its extreme forms (like veganism) can sometimes be dangerous for pregnant women, children, old people (sorry, there were several cases, some of them in the media also, not my invention). May God give you the wisdom to make good choices in this as well as other areas of your life! We all learn all the time with God so don't worry, just implement what you know is true and good
I am glad if it helps, God bless you!
