If you go vegan, do your kids have to follow?

Jennifer Lopez has revealed that she’s made her twins join her on the strict new vegan diet. Okay, or not okay?

Parents worry about their children’s health and well-being. We’ll make sure they don’t eat too much junk food in one day, give them a good breakfast so they have energy at school and make sure they spend as much time as possible running around outside. But can you go too far?

Take Jennifer Lopez.

In an interview with US Weekly, JLo confirms she's dropped 4.5kg ahead of her 45th birthday on July 24, taking her from an Australian size 8 to a tiny size 6.  She says she also "got her family" to come along for the ride. Her six-year-old twins, daughter Emme and son Max, are also joining mum in vegan meals. But they're not all that happy about it.

"Sometimes my son will be like 'I want American cheese. I don't like this vegan cheese,'"she told Extra. She added that she does allow her children to eat chips if they are extra hungry.

JLo recently separated from her much younger boyfriend, choreographer Casper Smart, 27. She'd been dating him since her split with husband, and  father of her children, Marc Anthony in 2011.

The singer has cut out dairy, meat and gluten. She's been working with exercise physiologist Marco Borges who has also worked with Beyonce, Gwen Stefani and Shakira. She is now eating Borges' cherry chock bliss bars as well as quinoa enchiladas and black-bean burgers.

The star doesn't drink alcohol and says her six-hour dance rehearsals take care of all her exercise needs. "I'm not an exercise fanatic. I don't love it, but I do dance a lot for the shows, so that helps."

Some experts believe a vegan diet is harmful to children. Paediatric dietician Helen Wilcock told The Guardian, "Vegan children can be deficient in vitamin D, calcium, iron and possibly vitamin B12, so they need supplements."

Do you think Jennifer Lopez should ease up on her children's strict diet?
