Perfect skin is aptly described as milky white. Perfect teeth are said to be milky white, too. But milky white eyes could either mean you have cataracts or you’re dead.

Milk comes in many forms but it is essentially made of protein, calcium, vitamin C, and saturated fat. Some milk has more lactose than others.

Milk Appear White Why Does Milk Appear White

Milk’s white color

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 back light. Casein bounces light back to our eyes. The more fat and cream milk has, the whiter it appears. For non-fat and low fat milk they tend to look gray because they contain less amount of casein.

Milk and human health

The two most important components of milk are vitamin d and calcium. These two make milk a very healthy drink.  Calcium makes our bones and teeth strong, vitamin D does the same job, too.  As it is, milk is one of the healthiest drinks know to man. Milk has: 15% vitamin B-12, 29% calcium, 23% riboflavin, 25% vitamin D, 17& protein, 23% riboflavin, and 23% phosphorus.

Commercial milk comes from cow’s udder. Milk is then cooled 40 degrees F. Cows that produce milk are called dairy cows. They are bred as and fed for commercial milk production. New Zealand is the world’s top milk producing country.

How cows make milk

Cows eat special feeds which contain nutrients such as fats, water, protein carbohydrates, vitamins, and minerals. These nutrients move through the dairy cow’s digestive tract (reumen, reticulum, omasum, and abomasums) where they are broken down by   enzymes.

On the average a dairy cow makes around 8 gallons of milk every day, but some can produce as much as 12 gallons.

To make 8 gallons of milk a dairy cow must drink more than 18 gallons of water.

For kids aged between 1 and 12, they are advised to have 3 glasses of milk or its equivalent: fish, yogurt, and soya. On the other hand, chocolate milk has pretty much the same nutrients as milk except that white chocolate has more calories than an ordinary bar. While chocolate contains more artificial sweeteners.
