The United States dairy industry is a major contributor to the US food and nutrient supply. Dairy products are a major source of protein, calcium, and many essential vitamins not just in the US but all over the world. The US dairy industry also accounts for 16 percent of the greenhouse gas emissions from all of US agriculture, and contributes roughly 1.58 percent of the total US greenhouse gas emissions.

Undernutrition is a pressing global health challenge and contributes to the deaths of more than three million children under the age of five every year. Children who are considerably shorter than the median for their age are defined as stunted, and so far, nutritional interventions have been mostly unsuccessful at reducing stunting. Read More...
Dairy foods are probably best known for their beneficial effects on bone health. But the same vitamins and minerals from dairy that help to build and maintain strong bones—calcium, phosphorus, magnesium, zinc, and riboflavin—may also have a positive influence on the symptoms of pre-menstrual syndrome (PMS). Expanding on previous research that found as association between increased calcium intake and decreased risk of PMS symptoms, a new paper from a team of Turkish researchers suggests the suite of micronutrients provided by dairy may be successful at alleviating both the emotional and physical symptoms of PMS.

Babies born in resource-poor rural and semi-rural communities have a high risk of stunting, that is, being born short for their gestational age. Rates as high as 60% have been documented in one indigenous population in Guatemala. Stunting at birth predicts increased infant and child mortality as well as ongoing growth retardation. Growth retardation in turn carries a higher risk for impaired brain function and loss of economic productivity. In female infants, growth failure presents a greater reproductive risk for themselves and their eventual children due to intrauterine growth restriction. The issue is primarily a consequence of inadequate nutrition, and is considered to be a major public health challenge in developing nations. However, nutrition interventions carried out during the infant and toddler stages have had only limited success in either treating or preventing growth failure. Those aimed at maternal nutrition during pregnancy, primarily focusing on micronutrients, have produced positive, albeit modest, effects on newborn size. Interventions prior to conception have not been well studied in humans, but animal studies have shown promise. Read More...
For many years, researchers have been gathering and analyzing different sources of data to try to figure out definitively whether consuming dairy products has a net positive or net negative influence on cardiovascular health. Naively, the fact that dairy contains saturated fat suggests the proposition that it might raise the odds of having a heart attack or a stroke. However, the diversity of dairy fats, alongside a host of other health-promoting molecules found in milk, cheese and yogurts, has led many researchers to suspect the opposite might be true. A consensus has been forming that dairy products either have no noticeable effects or have protective effects on the cardiovascular system, though this has rested upon data drawn heavily from a few wealthy countries. A new study known as “PURE”— “The Prospective Urban Rural Epidemiology” study—has just filled in this gap. Taking in data from five continents, it reports that higher dairy consumption is linked to lower cardiovascular disease the world over. Read More...
For years it has not been clear how consuming dairy products affects one’s chances of developing the two main forms of inflammatory bowel disease, Crohn’s disease and ulcerative colitis. On the one hand, saturated fats are thought to contribute to the risk, and dairy products contain these. But on the other hand, various unique components of milk, yogurt and cheese, such as certain anti-inflammatory factors and, depending on the product, even particular bacteria, are thought to be protective. Now, by far the largest epidemiological study of dairy consumption and the development of these diseases has been published. It reports that people who consume milk are significantly less likely to develop Crohn’s disease than those who do not. The data for ulcerative colitis were less conclusive. Read More...
The defense attorney summed up. “The prosecution’s case against dairy fat’s alleged health misdeeds is flawed and circumstantial. The flimsy forensic evidence does not stand up to repeated scientific inspection. The accused just looked like one of the suspect crowd and became wrongly branded with their guilt.” Now, a clinical trial following an elderly population for a remarkable 21 years, as well as mounting independent evidence, reports on dairy fat’s innocence. Dairy fat is not associated with risk of cardiovascular disease (CVD). Four past articles in SPLASH! have also summarized related aspects of the growing body of scientific evidence supporting this conclusion. Read More...
Surprises upturn accepted routines and demonstrate how little we really know. A new class of immune cell type, innate lymphoid cells (ILCs), was recently and unexpectedly discovered in fresh breast milk, and it promises to radically alter scientists’ understanding of how milk protects babies from infections, and possibly much more. The ground-breaking scientific paper [1] describing this discovery was recently published in the prestigious Journal of the American Medical Association - Paediatrics by Babak Baban and three colleagues from Augusta University. The paper has the modest but revealing title “Presence and Profile of Innate Lymphoid Cells in Human Breast Milk.” Read More...
Juliet Capulet famously asked, “What’s in a name? That which we call a rose by any other name would smell as sweet.” Juliet was able to look past “Montague” and love Romeo in spite of his surname. But when it comes to food and nutrition, names matter. Case in point—plant-based “milks.” Their placement in grocery stores in the dairy case and the use of “milk” on their packaging can give the false impression that they are nutritionally equivalent to cow milk. Although plant-based milk alternatives offer many nutritional benefits and are produced to have the same texture and appearance as milk, they are not a suitable nutritional substitute for cow milk, particularly for children and adolescents.

Cow milk evolved to best meet the needs of baby cows, but lucky for human consumers of milk and dairy products, many of those needs cut across species’ boundaries. Take, for example, the numerous anti-inflammatory agents found in cows milk. Although slightly different in degree and type from those found in human milk, several studies demonstrate that these factors, including calcium and the amino acid leucine, influence human markers of inflammation, particularly those related to obesity and the metabolic syndrome. And unlike baby cows, humans need not consume a milk-only diet to reap these benefits—even adding just two servings of dairy a day can have positive effects on inflammation and, by extension, human health.
