The Hong Kong Consumer Council has released a comprehensive analysis of 24 frozen sweet corn and pea samples, revealing that frozen peas consistently deliver higher levels of dietary fiber, vitamin C, and beta-carotene than their sweet corn counterparts. Conducted between November and December 2022, the test covered 10 sweet corn and 14 pea products purchased from local supermarkets and department stores across the city. While mixed frozen vegetables—often called “three-color beans”—remain a polarizing pantry staple, the findings suggest that even frozen options can be surprisingly nutritious and worth a second look.
Nutritional Showdown: Peas vs. Corn
The council’s laboratory results showed a clear nutritional gap between the two vegetables. Per 100 grams, sweet corn samples contained between 2.13 and 4.81 grams of dietary fiber, while peas ranged from 4.76 to 8.42 grams. Notably, nine pea varieties qualified as “high-fiber foods”—meaning they contain at least 6 grams of fiber per 100 grams—including products from Select, EarthBound Farm, Emborg, Topvalu, and Woolworths.
Vitamin C levels also favored peas. Sweet corn samples delivered anywhere from undetectable amounts to 6.5 milligrams per 100 grams, whereas peas offered between 7.9 and 21 milligrams. Ten pea brands met the “vitamin C source” threshold of 15 milligrams per 100 grams, with Woolworths Australian Peas and M&S British Garden Peas leading the pack.
Beta-carotene—a precursor to vitamin A—followed the same trend. Sweet corn averaged 23.5 to 50.5 micrograms per 100 grams, versus peas which ranged from 233 to 362 micrograms. Topvalu’s organic sweet corn performed best among corn samples, while Almaverde Bio’s organic extra fine peas topped the pea list.
Heavy Metal Traces – A Non-Issue for Safety
All samples were free from mycotoxins, mercury, and antimony. However, trace amounts of lead, cadmium, and chromium appeared in a number of products—always within Hong Kong’s safety limits. Lead was detected in three sweet corn and 11 pea samples, ranging from 0.006 to 0.042 mg per kilogram. The highest lead levels were found in M&S Supersweet Sweetcorn and Woolworths Australian Peas. One sweet corn sample (Meadows) contained 0.006 mg of cadmium. Chromium appeared in two sweet corn and nine pea samples, with EarthBound Farm Organic Sweet Corn and Woolworths Australian Peas again showing the highest levels.
Consumer Council emphasized that all detected levels comply with local standards, posing no health risk to consumers.

What This Means for Your Freezer Aisle
This test underscores a simple takeaway: frozen vegetables retain significant nutritional value and can be a convenient, affordable way to boost daily fiber and vitamin intake. For those who typically shy away from peas due to their grassy flavor, the data suggests it may be worth experimenting—stirring them into fried rice, soups, or pasta dishes can mellow the taste while reaping the benefits.
Prices ranged widely, from HK$4.40 to over HK$15 per 100 grams, so cost-conscious shoppers may find excellent value in lower-priced 5-star options like Meadows or Select. As the council notes, product prices and quality can change, so checking labels for fiber and vitamin content remains a smart habit.
For readers exploring further Consumer Council reports, recent tests on non-stick cookware, processed meatballs, chicken essence, and mouthwash offer additional insights into everyday products. No matter which frozen vegetable you choose, the key is to keep your freezer stocked with options that support a balanced diet—and perhaps give that bag of peas a second chance.
