Dairy nutrition
Besides tasting delicious, dairy sources have a lot of nutrition and health benefits such as protein, calcium, and beneficial bacteria (in cultured dairy).
These foods contain essential amino acids such as leucine, isoleucine, glutamine, phenylalanine, proline, and lysine, just to name a few. (1)
These fancy-sounding branched-chain amino acids help your body regulate blood sugar levels. (2)
Dairy also has bioactive peptides that are said to positively impact human health, including endocrine, cardiovascular, and nervous system benefits. (3)
Like all food groups, each type of dairy food has a different amount of nutrients and dietary protein in it. Keep reading and learn which ones are the highest.
Health benefits of dairy
Increasing protein intake is linked to many health benefits including weight loss and a lower risk for heart disease. There are so many delicious dairy products to choose from, but which is best?
The calcium in dairy is linked to better bone health. Additionally, dairy in milk is also linked to better energy regulation and a lower risk for bone diseases like osteoporosis. (4)
As you care for your health, begin to read nutrition labels. Some types of dairy food will have more satiating fat than others, while some food products might not have the amount of protein you need.
Your protein needs depend on your personal macros, which you can calculate using my free macro calculator.
The good news is that if you need to eat more protein, dairy has essential nutrients and is very easy to add to your meals.
High protein dairy foods
Let's look at all the different types of food and dairy proteins they have.
Dairy products are wonderful sources of protein, but each type will have a different amount.
There are various types of proteins and each protein will have a unique set of amino acids. Amn acids are the building blocks of protein.
There are 22 amino acids. 9 amino acids cannot be made in the human body and must be obtained from food. These are called essential amino acids.
Whey protein
Nutritional information for 30g of whey protein: 24.5 g protein, 13.9 g net carbs, 0.9 g fat, 124 calories.
Whey protein and casein protein are the two types of milk proteins. Casein is 80% of the protein found in milk. The other 20% of milk protein is whey protein. (5)
Whey protein is a dairy product and you'll often find it sold as whey protein powder that you can add to food or protein shakes.
There are usually about 25 grams of protein in 2 scoops of powder (which is about 30 grams).
These are the different types of whey proteins:
- Whey Protein Isolate - Processed to remove the fat and lactose. It is usually 90% protein.
- Whey Protein Concentrate - Contains low levels of fat and carbohydrates. They range from 30% to 90% protein.
- Whey Protein Hydrolysate - A predigested form of why protein. It is easiest to digest.
Milk
Nutritional information for 1 cup of milk: 7.7 g protein, 11.7 g net carbs, 7.9 g fat, 149 calories.
For this type of milk, we are talking about cow's milk rather than almond, rice, or a non-dairy alternative. Milk proteins have important amino acids in them such as albumin and immunoglobulin.
Milk is considered a full protein because it contains all 9 essential amino acids. (6)
There are 8 grams of protein per cup of milk. This is the same amount in skim milk, low-fat milk, or whole milk. However, those adhering to a keto diet will likely choose to avoid milk as the carb and sugar count are quite high. 1 cup of milk contains 12g of carbs which soon add up, especially if you are drinking milky coffees such as cappuccinos or lattes.
Regular yogurt
Nutritional information for 1 cup of yogurt: 14.2 g protein, 1.9 g net carbs, 3.6 g fat, 105 calories.
There is more protein in yogurt than in milk. One cup of natural unsweetened yogurt has 14 grams of protein.
There are functional benefits of eating yogurt as a snack. The beneficial bacteria help to build strong and resilient gut health which can help with improved immunity and improved mood. The protein will help you build lean muscle mass, which can help you lose weight.
Those adhering to a keto diet may opt to enjoy this very sparingly due to a higher carb count and always choose the natural unsweetened yogurt that has the lowest carb count.
Avoid fruit-based yogurts or chocolate-flavored yogurts which have added and unnecessary sugars.
Greek yogurt
Nutritional information for 1 cup of Greek yogurt: 25 g protein, 8.7 g net carbs, 1 g fat, 145 calories.
The protein content in Greek yogurt is even higher. There are 25 grams of protein in a cup.
Greek yogurt can be enjoyed in many different ways, but one of my favourite is in desserts like this 1-minute keto blueberry cheesecake!
Cottage cheese
Nutritional information for 1 cup of cottage cheese: 23.6 g protein, 10.8 g net carbs, 5.1 g fat, 183 calories.
There is a surprising 24 grams of protein in a cup of cottage cheese. That's enough protein to help you build lean body mass.
Enjoy it on its own or sprinkled with a few low-carb berries, or spread it across a slice of keto-friendly bread.
Cheese
Nutritional information for 1 cup of diced cheddar cheese: 30.2 g protein, 4.4 g net carbs, 44 g fat, 532 calories.
It's tough to say how much protein is in cheese since the cheese making process is different and affects this number. Your protein intake also depends on whether you are using shredded, melted, diced, or sliced cheese will affect how much cheese you consume in 1 cup.
Cream cheese only has 2 grams per ounce, but the carb count is quite low. I enjoy this baked smoked salmon roulade with cream cheese. The protein in salmon increases the protein content.
Mozzarella has 6 grams per ounce, and I use this powerhouse ingredient often! Fat head dough is one of the best ways to use mozzarella cheese (just make sure to get the low-moisture variety).
Swiss cheese has 12 grams of protein per ounce. Add it to your favorite burger or sandwich to amp up the protein.
Heavy whipping cream
Nutritional information for 1 fluid cup of heavy whipping cream: 6.8 g protein, 6.5 g net carbs, 85.9 g fat, 809 calories.
There are 7 grams of protein in a cup of heavy whipping cream. If you are looking for a delicious way for the whole family to enjoy this, try these creamed Brussel sprouts. They are addictive!
Ice cream
There is almost no protein in typical ice cream. There are just 2.3 grams of protein in ½ cup. Ice cream is mostly sugar.
