Introduction

It is a protein derived from milk and is common in products like milk, yoghurt, and cheese. While whey protein is assimilated quickly, casein protein is slow in digestion, which is why it is useful in supplying the body with a constant supply of amino acids for a long period of time. For anyone who wants to get many cases of casein into their bodies, it is very important to understand the types of foods that are rich in casein.

What is Casein?

It is a phosphoprotein, which is the major protein in cow’s milk, accounting for about 80% of the total protein content. The remaining 20% is whey protein, which is also a protein-rich fraction of the milk. As milk turns into cheese, casein proteins clump together to form curds, while whey proteins are left as the liquid that is separated from the curdling mixture. This means even if cheese contains less volume of milk compared to regular milk it has a much higher concentration of casein.

When ingested, casein clusters to form micelles which reduces its rate of digestion and breakdown. This leads to slow and continuous absorption of amino acids into the blood circulation as opposed to a normal meal. That is why casein is hailed as a ‘time-released ‘ protein while whey protein is described as a ‘fast-acting‘ protein.

Casein has a slow rate of digestion as compared to other proteins. It is useful in feeding the muscles amino acids for replenishment and growth during periods that it is inactive, such as at night. For this reason, specific casein protein powders are used to consume in the evening or even before sleeping.

Casein-Enriched Foods

Casein is the largest of the milk proteins, and it can self-assemble into nanostructures that can serve as reservoirs for nutrients and protect them from digestion in the stomach.

If you want to get more casein in your diet from whole foods, here is the list of foods that are high in casein:

1. Milk

Whey and casein are the two major protein products of milk. A cup of milk contributes 4 grams of protein, the casein comprising the bulk of this amount. Drink skim or 2% milk to get the casein and as little saturated fat and calories as possible.

2. Cottage Cheese

According to the nutritional value, cottage cheese contains more than 13 grams of casein protein per half a cup portion. Despite its slight lack of flavour, cottage cheese has a soft and spoonable texture, which allows it to be used in various meals and recipes.

3. Yoghurt

Yoghurt is a fermented product, and one cup of plain yoghurt contains 5-7 grams of casein protein and it has probiotics, which is good for health in terms of digestion and the immune system. For protein, Greek yoghurt is especially rich, containing approximately 22 g of protein in 226 g of the serving size.

4. Natural Cheese

As will be observed, many cheeses are loaded with casein as a result of the coagulation procedure, which compacts the casein proteins. In fact, only as much as 1 ounce of cheddar or mozzarella cheese has more than 5 grams of casein.

5. Milk Protein Concentrate

This dairy ingredient includes 40-90% milk protein by weight, which is made up of 80% casein. It’s mixed into protein bars, muscle mass supplements, meal replacement drinks, and, of course, protein powder.

6. Milk Protein Isolate

In its raw state, this FloraGlo ingredient is a purified protein, with 85 % to 95 % protein by weight, with the majority of it being casein. It’s commonly used in food production as well as in the production of products for sports nutrition.

7. Casein Protein Powder

Protein supplements are produced from dairy casein protein with each scoop having 15 – 30 grams of casein protein concentration. Casein powders are convenient for serving a large portion of time-released casein protein to the muscles.

8. Ice Cream and Frozen Yogurt

Who doesn’t like the idea of taking some sweets that will freeze their tongue? Here’s the exciting part! You can now forget about a cup of ice cream or frozen yoghurt and enjoy 4-6 grams of casein protein per serving.

9. Cream Cheese

Cream cheese owes its richness to casein and fat particles locked up within its extremely smooth matrix. Not only is it flavorful, but you will get a few grams of casein from this top favourite cheese spread.

10. Butter

Butter is a dairy product that results from churning milk and cream to separate the solid, culminating in the formation of butter. Hence, it retains protective casein proteins of approximately 0.9g in every tablespoon serving. When preparing a meal or any food preparation, it is advisable to use organic butter for quality health.

Casein Supplements

Protein is essential in the building of muscles, controlling hunger and loss of body fat thus, it is important to have sufficient intake of the food product. Whey protein powders and supplements present a convenient means through which you can intake adequate amounts of protein each day. The problem is their concentrates are much much more potent than whole food sources, and can deliver up to 50 grams of it in a single serving!

As compared to whey protein, casein protein digestion lasts between 5-7 hours, much longer than the whey protein’s 1-3 hours. This means casein releases amino acids to your muscles for consumption for a longer time than whey when you’re not eating or at night. It incorporates the major vitamins and minerals and is ideal for usage at any time. Blood amino acid concentrations may be low, for instance, Optimum Nutrition Gold Standard Casein.

Advantages of Casein 

The advantages of casein protein for health that can be derived according to research are as follows:

Preliminary research indicates casein protein offers unique health benefits beyond purely muscle-building applications:

• Reduces blood pressure by removing constricting forces on blood vessels.
• Lowers blood triglycerides.
• Reduction of blood coagulation properties.
• Boosts immune parameters.
• Antimicrobial effects are beneficial in preventing pathogenic microbes.
• Charted among the major milk protein allergens in infants.

Further research is required, but these preliminary results offer a clear indication of why casein cannot be regarded merely as a ‘supplement of choice’ exclusively for athletes and bodybuilders. In view of casein’s status as a whole protein of the highest biological value, it may contribute to overall health in a manner similar to other proteins of dairy origin.

Conclusion

Casein is a powerhouse protein known for its slow digestion, making it ideal for providing a steady release of amino acids, especially overnight. Incorporating casein-rich foods like milk, yoghurt, natural cheese, cottage cheese, Greek yoghurt, and even ice cream can support muscle recovery, growth, and overall health.

By including a variety of these foods in your diet, you can benefit from casein's unique properties and improve your overall nutritional intake. Whether you're looking to enhance athletic performance or maintain muscle mass, casein-rich foods are a valuable addition to your daily meals. Enjoy the sustained benefits of this remarkable protein for a healthier lifestyle.
