No doubt you did. But; did they have Temple Recommends?
Worthy MORMONs (self described) admit to being part time vegans.
The best thing I can tell you for your own mental health sake is if you don’t like what Mormons believe then stay out of their church and don’t bother them and they will likely do likewise for you.
OK Here is your answer in scripture.
Romans ch 14 14I know and am perfectly sure on the authority of the Lord Jesus that no food, in and of itself, is wrong to eat. But if someone believes it is wrong, then for that person it is wrong. 15And if another Christian is distressed by what you eat, you are not acting in love if you eat it. Don’t let your eating ruin someone for whom Christ died. 16Then you will not be condemned for doing something you know is all right.
17For the Kingdom of God is not a matter of what we eat or drink, but of living a life of goodness and peace and joy in the Holy Spirit. 18If you serve Christ with this attitude, you will please God. And other people will approve of you, too. 19So then, let us aim for harmony in the church and try to build each other up.
20Don’t tear apart the work of God over what you eat. Remember, there is nothing wrong with these things in themselves. But it is wrong to eat anything if it makes another person stumble. 21Don’t eat meat or drink wine or do anything else if it might cause another Christian to stumble. 22You may have the faith to believe that there is nothing wrong with what you are doing, but keep it between yourself and God. Blessed are those who do not condemn themselves by doing something they know is all right. 23But if people have doubts about whether they should eat something, they shouldn’t eat it. They would be condemned for not acting in faith before God. If you do anything you believe is not right, you are sinning.
Elsie even The Apostles did some things in their time for example shaving ones head which is not generally practiced today. But I believe what Paul says on meat and food should apply to the rest of our lives. Any church rules a church may ask of members would be like a Monastery having a requirement of something say perhaps silence?
Older and Modern Christianity has had practices many have done even related to eating or something in their life that were acceptable including fasting which is not necessarilly giving up all food but rather a specific food for example. Many churches practice it. Is that not part of what some sects call Lent?
