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.

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...

What’s in the Dairy Case? A2 Milk

What’s in the Dairy Case? A2 Milk

It used to be that the only decision you needed to make at the dairy case was full-fat or low-fat milk. Today, consumers are faced with dozens of alternatives to conventional cow’s milk, including milks free of lactose and “milks” made from soy beans, nuts, rice, and even peas (more about that in future articles). One of the newest alternatives to hit the shelves is A2 milk. It is marketed as an easier-to-digest version of conventional cow’s milk, differing by only one amino acid in one protein chain. But does the change in one protein really change the way A2 milk is digested? Read More...

A Cow’s Milk Reveals Her Health

A Cow’s Milk Reveals Her Health

Defense wins games. Ask any coach impatiently striding the sidelines. “The defensive line-up must be ever vigilant and able to rapidly neutralize the attacking incursion, which may come from any direction. You cannot wait for help from the cover defense! Any defensive lapse will be ruthlessly exploited by this opposition and all will be lost,” shouts the coach at spent and cowed players as the bell signals the end of their halftime break. Coaches could learn a lot more about defense from biology. An exemplar defensive strategy par excellence is used by mammals, especially dairy cows, where the defensive system is the animal’s immune system, the best in the league, and the opposition threat is microbial infection.

Camel’s Milk Offers Hope Against Diabetes

Camel’s Milk Offers Hope Against Diabetes

A little over a decade ago, an article appeared in a journal devoted to diabetes research claiming that the disease did not exist among the camel-milking drinking Raica community, a group living in the desert of northwest India, in the state of Rajasthan. The study had surveyed more than 2,000 people. The defining factor in the Raica community’s healthy blood glucose levels appeared to be their camel milk consumption, not genetics, nor a holistically healthy lifestyle. Read More...

Assessing the Evidence Around Perfluoroalkyl Substances

Assessing the Evidence Around Perfluoroalkyl Substances

For approximately the past decade, scientists have started to wonder about potential hazards that could be posed to human health from chemicals collectively known as perfluoroalkyl substances (PFAS). These chemicals are widespread in the environment globally—they have been used in manufacturing products such as food packaging and textile coatings since the 1950s, and are now detectable in the food chain, and even in dust and dirt. Since these chemicals can accumulate in the body, researchers are studying how they might be passed from mother to infant. This appears to happen to some extent via the placenta and to a lesser extent via human milk. Such findings should not dissuade mothers from breastfeeding, however, because the levels of PFAS in infant formula have sometimes been found to be higher than those of human milk. Read More...

Fresh or Frozen: The Facts about Freezing Milk

Fresh or Frozen: The Facts about Freezing Milk

The first thing that comes to mind when many people think about freezing milk is ice cream. Ice cream, frozen yogurt, and custards are all sweet treats that are notable for their creamy consistency. Yet milk that has been frozen sometimes seems less appealing once it’s brought back to a liquid state. Though some might not prefer milk that has been previously frozen, the ability to freeze and store milk and dairy products can be a safe and economical way to provide beneficial nutrition that people need. Likewise, the ability to keep human milk frozen for one’s own child helps families around the world every day. A common concern about freezing milk—whether produced by human or cow—is whether nutrients are lost in the process. So what, exactly, happens when we freeze milk? Read More...

Food and Medicine: Dairy Reduces Markers of Chronic Inflammation

Food and Medicine: Dairy Reduces Markers of Chronic Inflammation

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.

Drinking More Milk Associated With a Lower Risk of Cognitive Disorders

Drinking More Milk Associated With a Lower Risk of Cognitive Disorders

Increased age brings with it a greater risk of cognitive decline and disorders such as dementia and Alzheimer’s disease. The lack of effective treatments for these cognitive disorders has spurred the search for factors that can prevent or slow cognitive decline. One of the factors that has attracted a lot of interest is nutrition, and it turns out many of the things we eat or drink could play a role in preventing cognitive decline. Read More...

High Dairy Consumption is Associated with Better Short-Term Memory in Men

High Dairy Consumption is Associated with Better Short-Term Memory in Men

Eating dairy products positively influences brain function, with higher dairy intake associated with improved cognitive ability and short-term memory, and reduced cognitive decline and dementia. However, previous studies that looked at these associations could not rule out the effects of confounding factors such as genetics and family environment, which are also known to affect cognitive ability and food intake.
