From what I've read, it doesn't have an effect.

I'm sure there are sources that say otherwise, though.

There's also this. I know the actual website is biased, but they link to the studies.

It's not just a joke, it's true too. Feel free to look it up yourself.

Also, a vegan diet is healthy at every stage of life. You don't have to take my word for it. There are multiple sources saying so.

Edit: person below me blocked me before I could respond. Can't even look at the source they posted.

As for another source, here and here.

Keep following that feeling. It's worth it.

Edit: It's amazing how upset people get when you try to encourage someone to go vegan.
