Many of the price drops have been seen across fruit and vegetables - meaning healthy eating is finally becoming accessible for all.
Research collected by mySupermarket.co.uk found that the cost of a basket of 35 popular products has dropped in price in the space of 12 months.
Broccoli was 39% cheaper this year compared with April 2015.
Meanwhile onions have reduced in price by 18%, bananas are 15% cheaper and the price of fresh peppers has dropped by 16%.
Nutritionist Charlotte Stirling-Reed from SR Nutrition told The Huffington Post UK that she was pleased to see supermarkets being competitive, "especially with the price of healthy, fresh produce such as fruit and vegetables".
The price drops were recording using the mySupermarket Groceries Tracker, which monitors the cost of the same 35 most commonly bought grocery products on a monthly basis.
The research found that prices are also down from March 2016, with onions being 12% cheaper, fresh peppers being 7% cheaper, and broccoli, deli bacon and ham being 6% cheaper.
The only product to rise higher than a few percentage points was baked beans, which went up by 4%.
Kim Ludlow, mySupermarket’s managing director, said: "Every little bit certainly counts and any percentage drop can add up over time, meaning families can have more cash towards holidays or other treats.
"Of course you should always check prices before you shop, while prices have dropped overall there are several items that have risen since last year or even last month."
She added that the supermarket price war has continued to keep prices competitive across retailers.
For those looking to eat healthily on a budget, Charlotte Stirling-Reed says it's all about being savvy when shopping.
"For many people price is one of the reasons they quote for not choosing healthier options," she said. "But I’d encourage people to shop around and importantly to remember that a super diet doesn’t have to include expensive or luxury ‘superfoods’.
"Fresh, frozen and dried fruits and vegetables are all great options to include in a healthy, well-balanced diet.
"Moderation and variety are key, and supermarkets are clearly starting to make changes to help consumers feel more comfortable about choosing healthier options, which is certainly a positive move."
