My friend keeps making fun of her nieces business and saying mean things about her like she’s selling herself. Should I be careful with this friend?

Her business is a weight loss program. Whether you agree with the business or not, as a fellow entrepreneur I can say with confidence that I know how difficult it is to build a business and you need support from loved ones. I don't know this friend is so rude when she talks about others and I worry she says things about me too.
