The Effects of Dairy on Metabolic Risk Depend on the Type of Dairy Product Consumed

The Effects of Dairy on Metabolic Risk Depend on the Type of Dairy Product Consumed

Researchers have long been interested in understanding the effects of different types of dairy products on cardiometabolic health. Studies have looked at the effects of consuming different types of dairy on metabolic markers such as body weight, body fat, lean mass, or cholesterol. Although some studies have found that dairy products are associated with lower cardiometabolic disease incidence, other study results have been mixed or inconclusive. As a result, there’s still a lot researchers don’t know about the effects of long-term habitual dairy consumption on cardiometabolic risk, or the potential pathways linking the two. Read More...

PMS Symptoms Improve with Daily Recommended Dairy Intake

PMS Symptoms Improve with Daily Recommended Dairy Intake

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.

Droughts, Dairy and Discretionary Foods: Healthy and Environmentally Responsible Diets Can Mean Consuming More Dairy

Droughts, Dairy and Discretionary Foods: Healthy and Environmentally Responsible Diets Can Mean Consuming More Dairy

Often, dietary advice is given from singular perspectives. Public health professionals consider nutritional benefits first and foremost. Climate activists, concerned with the carbon footprints of modern lives, frequently lobby for vegetarianism. Few studies have sought to balance these, as well as other potentially competing demands. Yet, the United Nations’ Sustainable Development Goals (SDGs) require balance. They aim for both sustainable consumption patterns (Goal 12), and ending all forms of hunger and malnutrition by 2030 (Goal 2). Read More...

Genes, Diet, Environment: A Host of Factors Influence Human Milk Fatty Acids

Genes, Diet, Environment: A Host of Factors Influence Human Milk Fatty Acids

Fatty acids are the most variable macronutrient in human milk. So variable, in fact, that researchers believe each mother produces her own unique milk fatty acid signature. Unfortunately, not all fatty acid signatures are optimal for infant growth and development. Decades of research have demonstrated that docosahexaenoic acid (DHA), an omega-3 long chain polyunsaturated fatty acid (LCPUFA), is necessary to optimize the growth and development of infant neural functions. DHA also happens to be one of the most variable fatty acids in human milk, which means many mothers produce milk with concentrations that might not meet infant developmental requirements.

Three Investigations Find Consuming Dairy Staves off Death or Cuts Diabetes Risk

Three Investigations Find Consuming Dairy Staves off Death or Cuts Diabetes Risk

Diabetes is a major cause and death and morbidity around the world. The International Diabetes Federation estimates that about 9% of the global adult population has the type 2 form of the disease. Understanding dietary contributions to risk is therefore hugely important to global public health. Although genetic risk factors for type 2 diabetes do exist, the sheer rapidity of the rise in disease incidence over recent decades suggests that genetics is a minor part of the story. In a recent issue of the American Journal of Clinical Nutrition, three papers contribute further knowledge to the field. They all describe prospective studies that followed one or several large cohorts of adults and noted how much dairy they consumed. Overall, these studies confirm that consuming dairy does not raise diabetes risk, nor the risk of other cardiovascular diseases, and if anything, that it may be protective. Read More...

Chew on This: Softer Diets of Preindustrial Dairy Farmers Influenced the Shape of Their Skull

Chew on This: Softer Diets of Preindustrial Dairy Farmers Influenced the Shape of Their Skull

The human family tree has an extinct genus that is remarkable for their massive jawbones, molars, and cranial crests (picture a bony mohawk). All of these anatomical features are proposed adaptations to the tough, fibrous diet of genus Paranthropus; hard and chewy diets require large chewing muscles, which in turn require larger jaw and cranial bones (and crests!) for points of attachment.

Cheese May Be Good for Blood Circulation

Cheese May Be Good for Blood Circulation

Cheese is much more than just food. It is a part of the compelling story of ancient and modern human civilization. The huge range of cheeses today reflects the diversity of human taste and history. Cheese types also became a metaphor for public opinion. As Charles de Gaulle frustratingly said, “How can you govern a country (France), which has 246 varieties of cheese.” Adding to this impressive résumé of achievements, investigators recently demonstrated that hard cheese may also be good for blood circulation in older adults.

The Bitterness of the Maternal Diet Influences the Bitterness of Human Milk

The Bitterness of the Maternal Diet Influences the Bitterness of Human Milk

Human milk is known to provide a variety of nutrients that aid infants’ growth and development and are beneficial to their health. But as children grow a little older, they often don’t meet recommended dietary guidelines, particularly when it comes to eating enough fruits and vegetables. Read More...

Dairy-Containing Supplement Reduces Rates of Stunting in Babies Born in Resource-Poor Communities

Dairy-Containing Supplement Reduces Rates of Stunting in Babies Born in Resource-Poor Communities

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...

More Dairy Means Lower Cardiovascular Disease Globally

More Dairy Means Lower Cardiovascular Disease Globally

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...
