How Much Fat Is In Milk?

Do you drink skim or whole milk? The only difference between different types of dairy milk is how much fat is in the milk. The other nutrients are the same!

How Much Fat Is In Milk?

{Referral links are used in this post.}

We’re used to seeing fat in grams on other nutrition labels, so the percentage labeling that’s used on milk can be a little bit confusing.

Let’s say you have a jar with 100 ping pong balls inside. Ninety-eight of those ping pong balls are white and 2 are red. So 2% of your 100 ping pong balls are red.

Milk is like that jar of 98% white ping pong balls. Two percent milk just means that 2% of the milk is made up of fat. (So 98% of what is in that bottle is not fat.) When we’re used to looking at fat grams on a nutrition label, this percentage label doesn’t always make a lot of sense. So let’s talk a little more about fat percent, and what that means for the number of fat grams in the different types of milk.

How Much Fat is in Raw Milk?

Raw milk is not pasteurized. Most raw milk does not have the fat content adjusted, the way milk you’ll find in the grocery store does. So we consider raw milk to be “straight out of the cow.” (Read more about raw milk here.)

But not every cow is the same! Different breeds of cows make milk with different fat contents. And different cows of the same breed – even on the same farm – will make milk with different fat contents. And the same cow will make milk with a different fat content depending on how old she is and what stage of lactation she is in!

The first milk that cows make has the highest fat content. This milk is called colostrum. Colostrum is packed with antibodies and calories that calves need in the first day of life. Right after a cow gives birth, the colostrum is milked and fed to the calves; it does not become part of the human food supply.

After she makes colostrum, the fat content of a cow’s milk drops. Fat content is actually lowest around days 25-50 after calving. Then it starts to increase again, but it doesn’t reach its highest until around day 250 of lactation. At this point, the cow is making less total milk. When a cow makes less milk in a day, but the same amount of fat in a day, the milk will have a higher fat percent.

So how much fat are we talking about, straight from the cow? It depends on the breed, the farm, and the feeding program. What a cow eats directly affects how much milk she can make and how much fat it has. These are some averages for different breeds of dairy cows.

Cow Breed Percent Fat in Milk
Brown Swiss 4.20%
Holstein 3.69%
Jersey 4.80%
Milking Shorthorn 3.64%

Data from the USDA Summary of 2014 Herd Averages.

Jersey cows tend to make milk with the highest fat content. But Holsteins tend to make the most milk. Dairy farms choose the breed of cows they have based on their goals. If they are selling their milk to make cheese, they might want cows that can make milk with a higher fat content. If they are selling their milk to be used as “fluid milk” (what you buy at the grocery store), they might want cows who make more milk overall, and not be so concerned about the fat content. Many dairies will have one “primary” breed of cow, but include a few cows from other breeds. This can have a small effect on average fat content of their milk from that dairy.

Whole Milk

So now that we know that cows make milk with an average of 3.6-4.8% fat, what does that make whole milk? It turns out that whole milk isn’t actually “whole.” Some of the fat is removed to make whole milk have 3.25% fat. As you can see in the nutrition label above, this means that whole milk has 8 grams of fat in an 8-ounce serving.

You might expect the ingredients label on a container of whole milk to be pretty simple: milk. Most whole milk made in the United States has extra Vitamin D added to it (fortified).

2% Milk

How Much Fat is in Milk? from My Fearless Kitchen. Do you drink skim or whole milk? The only difference between different types of dairy milk is how much fat is in the milk. The other nutrients are the same!

This label is pretty simple. It’s 2% milk – so it has a 2% fat content. That means there are 5 grams of fat in one 8-ounce serving of milk. (That also means that 2% milk is 98% fat free!) Two percent milk is often called reduced fat milk. In order to use the label “reduced fat,” a food must have 25% less fat than the “reference food” (in this case, whole milk). Whole milk has 8 grams of fat per serving, and 2% milk has 5 grams of fat per 8-ounce serving. That’s 37.5% less fat in the 2% milk, which means that it can be called “reduced fat.”

The ingredient list for 2% milk includes reduced fat milk, Vitamin A, and Vitamin D. When fat is removed from milk, Vitamin A is also lost. (Vitamin A binds to fat.) Dairy processors add back Vitamin A at a level of 1200-2000 International Units per quart of milk. This brings the amount of Vitamin A back up to 6-10% of your recommended Daily Value. (Whole milk has 6% of your recommended Daily Value of Vitamin A.)

1% Milk

How Much Fat is in Milk? from My Fearless Kitchen. Do you drink skim or whole milk? The only difference between different types of dairy milk is how much fat is in the milk. The other nutrients are the same!

Following the trend here – 1% milk has a 1% fat content. That means that 1% milk is 99% fat free! There are 2.5 grams of fat in one 8-ounce serving. One percent milk is also called low fat milk. In order to be “low fat,” a food must have 3 grams or less of fat per serving. At 2.5 grams of fat per 8-ounce serving, 1% milk fits that criteria.

The ingredient list for 1% milk includes: low fat milk, Vitamin A, and Vitamin D. Just like with 2% milk, when fat is removed from milk Vitamin A is also lost. Dairy processors add this vitamin back to milk (fortified).

Skim Milk

How Much Fat is in Milk? from My Fearless Kitchen. Do you drink skim or whole milk? The only difference between different types of dairy milk is how much fat is in the milk. The other nutrients are the same!

This container of skim milk has a big “0%” label. Skim milk is fat-free milk. A fat-free food can have up to 0.5 grams of fat per serving. Fat-free milk has 0 grams of fat in an 8-ounce serving.

You are used to seeing this by now: the ingredients list for skim milk includes fat-free milk, Vitamin A, and Vitamin D. When all the fat is taken out of milk, the fat-soluble Vitamin A is also lost. Dairy processors add Vitamin A back to maintain a 6-10% recommended Daily Value of Vitamin A.

Other Nutrients in Milk

No matter the fat content in the milk you choose, the amounts of the rest of the nutrients are exactly the same.

Milk contains 30% of your recommended Daily Value of calcium. Milk that has been fortified with Vitamin D (like most milk made in the United States) has 25% of your recommended Daily Value of Vitamin D. Not many other foods contain calcium and Vitamin D, so milk is a very important source of these nutrients.

Milk also has 20% of your recommended Daily Value of riboflavin (Vitamin B2), 20% of your recommended Daily Value of phosphorus (important for strong bones), and 16% of your recommended Daily Value of protein (8 grams in an 8-ounce serving).

Milk has at least 10% of your daily value of niacin (important for enzyme function and metabolism), Vitamin B12 (important for red blood cells), and potassium (important for muscle activity and to maintain blood pressure). Whole milk typically has 6% of your recommended Daily Value of Vitamin A, while other types of milk have 10% (because they are fortified with Vitamin A).

It doesn’t matter if you choose your milk because of the way it tastes or because of a nutritional choice. All cow’s milk packs a huge nutritional punch!

    As far as adding milk to any thing a person cooks,,,, evaporated milk has less fat than whole milk and makes a thicker and richer flavor. Also less sodium…. would bever make mashed potatoes without my evapirated milk. Add to anything yoyr cooking! You can dilute if you wish. Don’t be an uniformed consumer, read the back label!

    “Milk is for baby cows and not humans.” I suppose you mean cows’ milk is for baby cows and not for humans.

    Likewise, meat is for the animals. That is, it is for the animals whose meat is part of their own constitution. They’re still using it, as it were.

    And, the carrot root is for the carrot plant. It needs it to live.

    The only thing free for us to eat is fruit and the product of fruit. Apples, tomatoes, mushrooms, nuts, etc. And annual plants.

    And vitamin D supplement pills are usually made from fish liver oil. I can see how drinking milk is worse.

    2 percent milk is more like 1/3, or 33 percent fat. Look at the label for 2 percent milk. It says 45 calories from fat out of 130 total calories. That is about 35 percent fat. The 2 percent comes from the weight of the butter fat relative to the total weight of the milk. Butterfat is light and fluffy, so it is only 2 percent of the weight.
