Dairy Diversity Ready to Grow

Sep 25, 2024

It might sound crazy to think that a product that’s already in 94 percent of U.S. households has room to grow, but the numbers indicate it’s true. Here’s what we’re talking about:

This comes from a study done by the International Food Information Council, supported by NMPF and the International Dairy Foods Association, on consumption habits among diverse U.S. populations. What’s striking is that, even though self-reported lactose intolerance among non-White populations runs at roughly 30 percent (according to the same study), clear majorities among Black, Hispanic and Asian/Pacific Islander populations haven’t even tried milk that addresses that intolerance, forgoing an option that provides 13 essential nutrients. And presumably, some of those non-milk drinkers are in that 6 percent who don’t have it in their refrigerators.

(And conversely, some of that 94 percent must include lactose-intolerant consumers. Are they taking lactase pills to aid in digestion? Are other household members the milk drinkers? There’s still much to know.)

The point is this: At a time when the committee drafting recommendations for the next Dietary Guidelines for Americans is looking at nutrition science and contemplating recommendations that are appropriate to the lived experiences of a wide range of Americans, it’s important to meet people where they are. For the overwhelming majority of them, that means a place where they have milk in the fridge. Those who aren’t there are in a place where awareness of the numerous ways to benefit from dairy nutrition, regardless of lactose tolerance, isn’t what it needs to be.

Analysis of greenhouse gas (GHG emissions) in the Canadian swine sector found that CH4 emissions from manure were the largest contributor to the overall emissions, followed by emissions from energy use and crop production.

This innovative project, "Improving Swine Manure-Digestate Management Practices Towards Carbon Neutrality With Net Zero Emission Concepts," from Dr. Rajinikanth Rajagopal, under Swine Cluster 4, seeks to develop strategies to mitigate greenhouse gas emissions.

While the management of manure can be very demanding and expensive for swine operations, it can also be viewed as an opportunity for GHG mitigation, as manure storage is an emission source built and managed by swine producers. Moreover, the majority of CH4 emissions from manure occur during a short period of time in the summer, which can potentially be mitigated with targeted intervention.

In tandem with understanding baseline emissions, Dr. Rajagopal's work focuses on evaluating emission mitigation options. Manure additives have the potential of reducing manure methane emissions. Additives can be deployed relatively quickly, enabling near-term emission reductions while biodigesters are being built. Furthermore, additives can be a long-term solution at farms where biogas is not feasible (e.g., when it’s too far from a central digester). Similarly, after biodigestion, additives can also be used to further reduce emissions from storage to minimize the carbon intensity of the bioenergy.
