WASHINGTON — Walmart, one of the largest retailers in the U.S., announced Wednesday that its in-house brands, including the popular "Great Value" brand, would phase out synthetic dyes and other artificial ingredients soon.

In an emailed statement, a Walmart spokesperson said more than 30 ingredients would be phased out, but didn't lay out a definitive timeline for when those ingredients would be dropped from the manufacturing process.

Walmart said that all private brand food items sold by the company, under the Great Value, Marketside, Freshness Guaranteed and bettergoods brands, would be affected by the change.

Great Value products and other similar brands sold by Walmart are often bought by consumers as cheaper "generic" versions of name-brand products.
