Sharon Lastique is the owner of “Healthy on Lark,” a vegan eatery that features flavors from around the world.

Lastique has been vegan most of her life, while some have just started this month. Many are encouraged to go vegan for the month of January, also known as “Veganuary,” as encouraged by a non-profit organization.

It may be trendy, but Lastique says it doesn’t have to be a temporary thing.

“There have been many studies that show improvement in people who are recovering from cancer, heart disease, lowering cholesterol … the list goes on and on,” she said.

But don’t clear out your fridge just yet.

“Just because something is plant-based doesn’t mean it's necessarily the right decision,” said Rosie Urkevich, a registered dietician who specializes in vegan and gluten-free diets.

Urkevich says the safest way to transition into an all-vegan lifestyle is gradually, and be sure to consult with your doctor.

“There’s a couple of nutrients that are of concern when you go vegan, there are certain vitamins and minerals that you could inadvertently become deficient in,” Urkevich said.

She said supplements are an option, but adds supplements like Omega-3 and Vitamin D can actually have animal origins.

To make sure you’re getting enough protein and iron, Urkevich recommends filling your plate with things like lentils, soy and calcium-set tofu – and of course, plenty of vegetables.
