Walmart's new "Great for You" label is a step in the right direction, but still includes some risky foods.

Walmart announced Tuesday that customers will start seeing it's new "Great for You" label on select healthier food products this spring, a move that spurred both praise and criticism. The voluntary labeling system now joins a host of others on the market, potentially causing more confusion among shoppers. "Great for You joins NuVal, Guiding Stars, Facts Up Front, Heart Check, and other approaches that seek to steer consumers toward healthier diets," Michael F. Jacobson, executive director of the Center for Science in the Public Interest (CSPI) said in a statement. "That proliferation of sometimes-inconsistent nutrition symbols on store shelves and packages indicates the need for the U.S. Food and Drug Administration to develop one excellent system that would replace all the voluntary approaches."

The Food and Drug Administration has been working on standards, but they haven't been released yet, and Walmart said it didn't want to wait any longer in creating a simple icon to help direct shoppers to healthier choices.

The company said it developed its criteria by looking at government guidelines and working with health organizations and other parties interested in healthy eating. Shoppers will initially see the labels on Marketside produce beginning in April, and then the company will start rolling out the label on its Walmart Great Value packaged products. A company spokesperson said the two-step process starts by encouraging people to eat more fruits, vegetables, fiber-rich whole grains, low-fat dairy, nuts and seeds, and lean meats. The second goal is to limit the amount of sodium, added sugar, and fat (total, saturated, and trans fats) in products.

According to MSNBC:
o Raisins will get the icon, but dried fruit with sugar added would not.
o Plain oatmeal qualifies, but sweetened oatmeal does not.
o Brown rice will get the label. White rice will not.
o Plain or artificially sweetened yogurt makes the cut, but yogurt sweetened with sugar does not.

"Today's announcement by Walmart is yet another step toward ensuring that our kids are given the chance to grow up healthy," first lady Michelle Obama said, noting that last year Walmart committed to making fruits and vegetables cheaper. (Some criticized Walmart for not focusing on organic fruits and veggies.)

CSPI credits Walmart for highlighting many healthy foods with its new labeling system, but notes that the system isn't foolproof.

Here are some products that might not actually be so healthy:

Factory-Farmed Eggs & Meat
CSPI criticizes the fact that Walmart is listing cholesterol-rich eggs as healthy. In addition, some of its meats are injected with extra saltwater.

The healthy labeling system also ignores antibiotics and hormones that often wind up in meat, poultry, and dairy raised in industrial farming conditions.

Salty Canned Veggies
Although Walmart is in the process of reformulating and dropping sodium and sugar content in more than 100 food products, canned veggies still are a hidden source of excess sodium in the diet. Your best bet is to choose fresh or frozen veggies. That way, you also avoid the harmful exposure to BPA, a plastic chemical used in the lining of cans used for most canned soups and vegetables.

Nutrient-Poor Apple and Grape Juice
Apple and grape juice are the least nutritious juices at the store, and juice companies often use them as the main ingredients in juice products because they're cheaper than more exotic, healthier fruits. Another concern? Many nonorganic juices are testing positive for lead, arsenic and fungicide contamination. It's best to choose organic juices, or better yet, just eat the fruit whole for a healthy fiber boost.

Processed Grains
Even though brown rice will get the label but white rice will not, there's still some question as to the labels use on processed grains. Grain foods that contain more blood-sugar-spiking, obesity-promoting refined white flour than whole grains are allowed to bear the new healthy label.
