Plant-based diets are said to be full of health benefits, but one consumer savings expert says they can also be a great way to save on your grocery bills.

Citing a recent U.S. study, savings expert Jackie Rosen says by switching to a vegetarian or vegan diet, a consumer can save up to $750 per year.

But what’s the best way to incorporate a plant-based diet into your life, without breaking the bank?

First, Rosen suggests, plan ahead with a list before going grocery shopping.

“Always write your list out, think about what you want to eat over the next week, plan your meals,” Rosen said in an interview on CTV’s Your Morning.

Also, be mindful of sale prices. “You can find a lot good fruits and veggies at a regular grocery store, you don’t necessarily need to go to a specialty store,” Rosen said.

Shopping in season can also save you money.

“Right now, it’s harvest season: Apples, pumpkins, squash and potatoes are really big right now, these are wonderful nutritious items that you can add to your meals,” Rosen said.

Switching to a plant-based diet is also a good opportunity to buy local. “If it’s not travelling a far distance, you’re not going to be paying that transportation money, the savings are passed on to the consumer.”

On the question of whether organic produce is worth the premium price, Rosen suggests keeping in mind the “dirty dozen” list of thin-skinned fruit and veg that are typically more susceptible to retaining pesticide residue. For instance, Rosen says it’s a good idea to buy organic apples, strawberries and nectarines.

But thicker-skinned produce, such as avocado, pineapples and sweet corn, can be purchased non-organic.

Rosen also suggests limiting the amount of organic items you buy. “Your favourite items, stick to those organic and buy regular for the rest.”

Frozen veggies and fruits can also help you save in the long-term as they can be stored in the freezer and used throughout the year.

“It’s got just as many nutrients as if you were to eat something fresh,” Rosen said.
