A Jumping Spider That Provides Milk and Maternal Care

A Jumping Spider That Provides Milk and Maternal Care

High school science classes the world over teach that mammals are unique because females furnish their young with milk. The reality is somewhat more nuanced, and depends on your definition of milk. Indeed, there are various specialized food sources that a few non-mammals provide their offspring, among these the antibody-containing epidermal mucus found in some fish and trophic eggs in amphibians (as well as other classes of animal). In a recent issue of the journal Science, a group of researchers associated mainly with the Chinese Academy of Sciences report on the curious life of an ant-mimicking jumping spider, Toxeus magnus. They find that females of this species produce protein-rich droplets for their offspring to consume that are essential for the youngest spiders’ survival. Curiously, female offspring continue to drink this milk even after they have become sexually mature. 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...

The Magic of Milk in the Morning

The Magic of Milk in the Morning

Odds are, your mother told you “breakfast is the most important meal of the day.” And, as is usually the case, your mother was right. Scientific studies continually support this folk wisdom—people that eat breakfast weigh less, are less likely to gain lost weight back, and have more stable blood sugar levels throughout the day compared with those who skip the first meal of the day. Not all breakfast foods offer these health benefits, however. Sorry bagels and donuts, but studies consistently show that protein-packed breakfast foods may make the biggest impact when it comes to jump-starting your metabolism and limiting spikes in blood sugar and overall daily food intake. But a new study shows that you may be able to have your breakfast carbohydrates and eat them too—as long as you eat them with milk. Read More...

Large Study Finds Consuming Milk Cuts the Odds of Crohn’s Disease

Large Study Finds Consuming Milk Cuts the Odds of Crohn’s Disease

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...

Dairy Fat Is Not Associated with Heart Disease

Dairy Fat Is Not Associated with Heart Disease

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...

Cow Milk Can Protect the Gut from Alcohol-Induced Gastric Ulcers

Cow Milk Can Protect the Gut from Alcohol-Induced Gastric Ulcers

Ulcers can be a real pain in the gut, and they’re unfortunately quite common, affecting more than 10% of the world’s population. Drinking alcohol, smoking, stress, and microbial infections are all known to exacerbate these ulcers. Read More...

Milk is Alive with Mom’s Cells

Milk is Alive with Mom’s Cells

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...

Almond “Milk”: A Case of Identify Theft?

Almond “Milk”: A Case of Identify Theft?

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.

Relationship Between Breastfeeding and Allergies: It’s Complicated

Relationship Between Breastfeeding and Allergies: It’s Complicated

The past few decades have seen a steady rise in the worldwide prevalence of allergic diseases, which has spurred research aimed at figuring out ways to prevent allergies [1]. The first six months of life are thought to offer a window of opportunity for preventing allergies. “Nowadays, most researchers and clinicians are trying to aim at this window of opportunity,” says Professor Daniel Munblit of Imperial College London, Sechenov University, and inVIVO Planetary Health.

Milk Casein Proteins: Ancient, Diverse, and Essential

Milk Casein Proteins: Ancient, Diverse, and Essential

Grab your nearest carton of milk. Find the nutrition label. Under total fat, you’ll likely find information about how much of that fat is saturated, unsaturated, and even trans fatty acids. Under carbohydrates, you’ll learn how much fiber and sugar your milk contains. But there is just one row of information when it comes to protein, giving the false impression that milk protein is not nearly as complex as milk fat or sugar. However, cow milk is made up of two different types of proteins, whey and casein, the majority of which is are caseins. There are four different subtypes of casein proteins, and for each of the four subtypes, there are dozens of different genetic variants. How’s that for complex? Read More...
