According to Gram Research analysis, a 2026 study found that offering SNAP participants discounts on 1% milk increased their purchases of this healthier option by up to 21% compared to before the program. The Add Milk discount program successfully encouraged families to buy lower-fat milk and reduce higher-fat milk purchases, though the full effect took over 6 months to appear. However, discounts did not increase fat-free milk purchases, showing that incentive programs work best for products people are already somewhat interested in buying.
A new study looked at how offering discounts on lower-fat milk helps families who receive food assistance (SNAP) make healthier choices at the grocery store. Researchers tracked what happened when a large retailer offered special deals on 1% milk to SNAP participants through a program called Add Milk. The results show that discounts do encourage people to buy healthier milk options, though it takes several months to see the full effect. This research is important because most programs focus on fruits and vegetables, but this study shows we can also help people choose healthier versions of other foods they already buy.
Key Statistics
A 2026 research article analyzing transaction data from a major retailer found that SNAP households increased spending on 1% milk by up to 21% when offered discounts through the Add Milk program, compared to their pre-program purchasing patterns.
According to a 2026 study of the Add Milk discount program, the incentive took over 6 months to show its full impact on SNAP household milk purchases, demonstrating that dietary behavior change through price incentives occurs gradually rather than immediately.
A 2026 analysis of discount incentives found that while lower-fat milk purchases increased among SNAP participants, fat-free milk spending was not affected by the same discount program, suggesting price incentives work better for products with existing consumer interest.
The 2026 Add Milk study showed that higher-fat milk sales decreased among SNAP households when lower-fat alternatives were discounted, indicating successful substitution toward healthier options despite limited impact on the healthiest choice available.
The Quick Take
- What they studied: Whether offering discounts on lower-fat milk encourages families receiving food assistance to buy healthier milk instead of higher-fat versions
- Who participated: SNAP households and non-SNAP households who regularly bought milk at a large retailer participating in the Add Milk discount program
- Key finding: When SNAP families got discounts on 1% milk, they increased their spending on it by up to 21%, and they bought less high-fat milk. However, the program took over 6 months to show results
- What it means for you: Discount programs can help people make healthier food choices, but they work slowly and may not change all eating habits. If you receive SNAP benefits, looking for milk discounts could help you save money while choosing healthier options
The Research Details
Researchers studied what happened when a major grocery store chain offered discounts on lower-fat milk to families receiving SNAP benefits through a program called Add Milk. They looked at actual shopping data from the store to see how much milk people bought before and after the discounts started. They compared what SNAP families bought to what non-SNAP families bought to understand the real impact of the discount program.
The researchers used two statistical methods to analyze the data. The first method compared changes over time between the two groups. The second method looked at what happened right when the program started to see the immediate and long-term effects. This approach helps separate the discount’s effect from other things that might change shopping habits.
Using real shopping data from actual stores is more reliable than asking people what they buy or watching them in a lab. This study shows what really happens when grocery stores offer discounts, which helps policymakers understand if these programs actually work in the real world. Most nutrition programs focus on fruits and vegetables, so this research is important because it tests whether discounts work for other healthy foods too.
This study used actual transaction data from a real retailer, which is very reliable because it shows what people actually bought, not what they said they bought. The researchers compared SNAP and non-SNAP households to understand the discount’s true effect. However, the study looked at only one retailer in one location, so results might be different in other areas. The study also didn’t track whether families actually ate the healthier milk or if they just bought it and didn’t use it.
What the Results Show
The Add Milk discount program successfully increased how much SNAP families spent on 1% milk, up to 21% more than before the program started. This means families were choosing the lower-fat option more often when it was discounted. At the same time, these families bought less of the higher-fat milk options, showing they were making a substitution toward healthier choices.
However, the program did not increase spending on fat-free milk, which is the healthiest option. This suggests that discounts work best when people are already somewhat interested in a product. Fat-free milk may have tasted too different or been less appealing to families, so the discount alone wasn’t enough to get them to switch to it.
An important finding was that the program took over 6 months to show its full effect. This means people don’t immediately change their shopping habits when a discount starts. It takes time for families to notice the discount, try the product, and make it part of their regular shopping routine.
Flavored milk sales were not affected by the discount program. This suggests that when families buy flavored milk, they’re making a choice based on taste preference rather than price. Even with discounts on healthier options, families who want flavored milk will still buy it. Sales of higher-fat milk did decrease, showing that at least some families switched from the less healthy option to the discounted 1% milk.
Most nutrition assistance programs focus on fruits and vegetables because these are clearly healthy foods. This study adds to a growing body of research showing that discounts can encourage healthier eating choices. However, it also shows that incentive programs have limits, they work better for some products than others. The finding that it takes 6 months to see results is important because previous studies on fruit and vegetable discounts have shown similar delays, suggesting this is a common pattern in how people change their shopping habits.
The study only looked at one large retailer, so the results might be different at smaller stores or in different communities. The researchers didn’t know if families actually ate the milk they bought or if they just purchased it. The study didn’t include information about family income, education, or other factors that might affect shopping choices. Additionally, the study period and specific location weren’t detailed, so it’s unclear how these results would apply to other regions or time periods. Finally, the study couldn’t determine why fat-free milk wasn’t purchased more: it could be taste, texture, or other reasons not explored in this research.
The Bottom Line
If you receive SNAP benefits and buy milk regularly, look for discount programs like Add Milk at your local grocery store. Choosing 1% milk instead of higher-fat options can help you eat healthier while saving money. Give the program time to work: it may take several months before you see the full benefit of the discounts. This recommendation has moderate confidence because the study shows real results, but it was conducted at only one retailer.
SNAP participants who buy milk regularly should pay attention to this research, as it shows discounts can help them make healthier choices. Grocery store managers and policymakers should care because it shows discount programs can work for foods beyond fruits and vegetables. Parents buying milk for their families might find this helpful for making budget-friendly, healthy choices. People who don’t buy milk regularly or who prefer fat-free milk may not see the same benefits.
Based on this study, expect to see changes in your milk purchases within 6 months of a discount program starting. The full effect of the discount may take even longer as you adjust your shopping habits. If you’re tracking health improvements from drinking lower-fat milk, give yourself at least 3-6 months to notice changes in how you feel or any health markers your doctor is monitoring.
Frequently Asked Questions
Do discount programs actually help people buy healthier milk?
Yes, according to a 2026 study, SNAP households increased 1% milk purchases by up to 21% when discounts were offered through Add Milk. They also bought less high-fat milk, showing real substitution toward healthier options, though results took 6 months to fully appear.
How long does it take for milk discount programs to work?
The Add Milk program took over 6 months to show its full impact on purchasing habits. This delay suggests people need time to notice discounts, try new products, and adjust their regular shopping routines before making lasting changes.
Will discount programs get people to buy fat-free milk instead of 1% milk?
The 2026 Add Milk study found that discounts increased 1% milk purchases but did not increase fat-free milk spending. This suggests discounts work better when people already have some interest in the product, and taste or texture preferences may prevent switching to the healthiest option.
Can incentive programs change what kind of milk families buy?
Partially. A 2026 study showed discounts successfully shifted SNAP households toward lower-fat milk and away from higher-fat options. However, flavored milk purchases weren’t affected, indicating price incentives work best for health-conscious substitutions rather than changing taste-based preferences.
Are milk discount programs as effective as fruit and vegetable incentives?
The 2026 Add Milk research shows milk discounts can work, but with limitations. While they successfully increased lower-fat milk purchases by 21%, they didn’t increase the healthiest option (fat-free milk), suggesting dairy incentives may have different effectiveness patterns than produce programs.
Want to Apply This Research?
- Track weekly milk purchases by type (1%, 2%, whole, fat-free, flavored) and amount spent. Record when you notice discounts and measure the percentage change in your 1% milk purchases month-to-month to see if incentive programs are working for you.
- Set a reminder to check your grocery store’s app or website weekly for milk discounts. When you find a discount on 1% milk, add it to your shopping list and track the savings compared to your usual milk purchase. Over time, this habit can help lower-fat milk become your default choice.
- Create a monthly report in the app showing your milk spending by type and total dairy spending. Compare your purchases before and after discount programs launch. Track not just what you buy, but also note any health changes you experience, such as improved digestion or energy levels, to connect the dietary change to real outcomes.
This research shows that discount programs can influence milk purchasing among SNAP participants, but individual results may vary based on location, store availability, and personal preferences. This study does not provide medical advice. Consult with a healthcare provider or registered dietitian before making significant changes to your diet, especially if you have lactose intolerance, dairy allergies, or other health conditions. The findings are based on one retailer’s data and may not apply universally to all grocery stores or communities. Purchasing healthier milk options does not guarantee health improvements without other lifestyle factors like overall diet quality and physical activity.
