35 Fun Facts About Milk

Learn about the nutrition, health benefits, and environmental impact of dairy and plant-based milks.

Milk is one of the most consumed beverages in the world.

The milk most people drink usually comes from animals.

But how much do you actually know about the milk? Are you clued up on the health benefits of milk?

Let's take a closer look at why milk is so healthy and beneficial.


Cow's milk is the most commonly consumed type of milk since cows produce more milk daily than other mammals.
But there are also other options, including goat's milk, almond milk, soy milk, oat milk, and lactose-free milk.

Raw milk can carry harmful bacteria, but it can be removed through a process called pasteurization.
Raw milk can carry harmful germs, such as Campylobacter, Cryptosporidium, E. coli, Listeria, Brucella, and Salmonella. These germs can pose serious health risks to you and your family.

In 1987, the FDA issued a regulation prohibiting the interstate sale of raw milk. However, some states do permit the intrastate (within the borders) sale of raw milk intended for human consumption.

Milk consists of 87% water. The remaining 13% is divided into protein, fat, carbohydrates, vitamins, and minerals.

Milk is a source of vitamin A, which helps support a healthy immune system.
Vitamin A is important for normal vision, immune health and human reproduction. Vitamin A also helps the heart, lungs, kidneys, and other organs work properly, and supports cell growth and dierentiation.

Some countries, such as Canada and Sweden, mandate that cow's milk should be fortified with vitamin D.
Vitamin D is an essential nutrient, especially when it comes to milk, as it helps your body absorb calcium.

Casein and whey protein are the two types of protein found in cow's milk. They're considered high-quality proteins as they both contain amino acids.
Whey protein is beneficial for improving mood and lowering stress.
Casein, meanwhile, may actually help to lower your blood pressure.

Milk contains a fair amount of sugar.
For every 7g of protein, you can generally expect 12g of sugar in return, meaning you're going to need to keep a close eye on your macros.

Lactose is a chemical naturally found in milk and other dairy products.
Lactase, on the other hand, is an enzyme produced in the small intestine that helps break down lactose.

Lactose intolerance happens when your small intestine does not make enough of a digestive enzyme called lactase.
Fortunately, there are lactase pills for when someone with lactose intolerance really wants to drink milk or eat some cheese!

People who chug large amounts of milk tend to puke because there's too much lactose for the body's lactase to break down.

Why is Milk White?
Milk appears white because of a protein called casein. Casein is made up of protein and fat. Lest you mistake it for an optical illusion, our eyes can see the white in milk because milk it doesn't absorb light at all. Instead, the white pigment throws backlight. Casein bounces light back to our eyes. The more fat and cream milk have, the whiter it appears.
For non-fat and low-fat milk they tend to look gray because they contain less amount of casein.

There's a blue-green-colored milk that's made from algae called Spirulina, which is also high in protein and minerals.

Goat milk is thicker and creamier than cow milk or plant milks, and goat milk has more nutrients that may offer health benefits.

Milk is a remarkably good alternative to sports drinks, like Gatorade, since milk is also high in electrolytes.

Milk is beneficial for your teeth because it contains high amounts of calcium, which is known for strengthening your enamel and helping your teeth fight off cavities.

Evaporated milk is created by evaporating 60% of the water in milk. The same percentage of water is removed when making condensed milk, but the difference with this type of milk is the added sugar.

More than just a superstition or a rehashing of the old home remedy of drinking a bowl of warm milk before bed, recent research has shown that milk taken from cows at night has significantly higher levels of tryptophan and melatonin, substances long known to promote and enhance sleep.

Two of the most popular plant-based milks are soy and almond milk.
Neither of them contains lactose, making them great alternatives for people who are allergic to milk or are lactose intolerant.

Out of all the kinds of plant-based milk, unflavored oat milk has the most calories and carbohydrates.

A breast infection called mastitis can make breast milk taste salty rather than sweet.

Lactobacillus acidophilus, a so-called good bacteria due to its beneficial properties, is found in milk. It’s responsible for turning lactose into lactic acid, as well as causing the drink to taste sour.

The irrational fear of milk is referred to as galaphobia.
An example of someone who has this strange phobia is NFL player Will Levis, who screams at the mere sight of milk!

Milk is able to cover coffee's bitterness by binding the proteins in milk with the polyphenol compounds (like tannins) that cause its bitterness.

The lactic acid that's produced by fermenting milk is used in skincare products, as it helps remove dead skin cells and moisturize the skin. Most skincare products use lactic acid from beet sugar or cornstarch, though.
