What Makes Dairy so Powerful?

What Makes Dairy so Powerful?

Dairy ingredients contain nutrients that cannot be synthesized by the human body, meaning that they are essential nutrients.  Milk is a good to excellent source of 13 essential nutrients (protein (amino acids), vitamin A, vitamin B12, calcium, vitamin D, iodine, niacin (vitamin B3), pantothenic acid (vitamin B5), phosphorus,  potassium, riboflavin (vitamin B2), selenium and zinc) and ingredients derived from milk contain varying levels of the nutrients. Including dairy ingredients in food and beverages improves the nutritional value of those products.  

Dairy ingredients provide functionality in a variety of food and beverage applications, including but not limited to gelation, emulsification, viscosity, water-binding, and whipping.  While the unique acid-stable nature of whey protein makes it suitable to low pH applications, the heat-stable nature of caseins makes it suitable to high-temperature applications.  The fact that lactose is a reducing sugar, make lactose-containing ingredients appropriate for applications that benefit from browning (baked goods).  Because milk fats melt near the body temperature of humans, dairy fats are suitable for a multitude of confections.

Proteins from Milk are Complete

Milk proteins (casein and whey) deliver the nine essential amino acid nutrients that meet human requirements, making them both complete proteins. They are also high quality proteins because they are efficiently digested and utilized by the body.

Many plant-based proteins only deliver some of these necessary nutrients, making them incomplete proteins. Also, anti-nutrient factors may be naturally present in some sources of plant-based protein (phytates in soy, for example), which may further decrease their protein quality for humans.

How Your Body Processes Proteins from Milk

You may know that your body needs amino acids, but did you know it needs them in a certain ratio? Proteins from milk deliver all nine essential amino acids, in just the right ratio, along with a unique combination of bioactive peptides (some which have a role in lowering your blood pressure) and minor proteins that have natural antibacterial properties (to boost your immune health). That’s why proteins from milk are unbeatable when it comes to delivering the strong inside your body.

Proteins play critical roles in protein systesis, tissue repair, and other vital processes. Casein gets digested and releases amino acids into the bloomstream slower than whey, maximizing the repair and rebuilding of our muscles, whereas whey gets digested and releases amino acids to the muscles more quickly, contributing to muscle mass and recovery.

Dairy's Sustainability Story is Simple

Beyond the Gram

Protein is a game of quality and quantity. You may be getting the right number of grams of protein per meal or day, but if you’re not consuming proteins from milk, you may be missing out on real results like leaner body mass, sustained energy, and more muscle strength.

Even whey and plant protein combination blends have been found to be less effective than whey alone for muscle protein synthesis, for example. This has been shown to be true when tested with both pea and wheat proteins, even when given at a higher dose than whey proteins.1 2 Make sure you’re getting the most out of your protein by checking your ingredient labels for proteins from milk.

Other nutrients in milk should also not be overlooked. Approximately 50% of Americans do not consume adequate amounts of dairy foods (>3 servings a day) and subsequently consumer below recommended dietary intake for the critical nutrients calcium, magnesium, vitamin A, and vitamin D. (3)
