Protect and build muscle while getting essential amino acids and calcium with this protein

Milk really does do a body good. It’s high in calcium, vitamin D and potassium. And it’s also rich in a beneficial protein called casein (pronounced ”KAY-seen“).

If you’re a regular dairy milk drinker, you’re already getting some benefits of casein. But you may want to consider adding more casein to your diet. Athletes and bodybuilders have been using casein protein powder for years. But the benefits of casein aren’t just for pro sports players.

“Protein is a vital part of any balanced diet,” says registered dietitian Elyse Homan, RD, LD. “But different proteins have different effects. Understanding how each protein works is beneficial, especially if you’re supplementing with it.”

What is casein?

Casein is the main protein found in dairy milk, which includes the milk from:

  • Cows.
  • Goats.
  • Sheep.

Casein makes up about 80% of the protein found in milk. The other 20% comes from whey protein.

“When you think of curds and whey,” Homan says, “the solid part is casein protein, and the liquid part is whey protein.”

Getting enough protein is important because protein has many jobs. It has to:

  • Carry out chemical reactions (like digestion).
  • Help your tissues and organs change and grow as needed.
  • Protect your body from viruses and bacteria.
  • Support your body’s movement by providing cell structure.

Casein vs. whey

Casein and whey have a lot in common. They’re both:

  • Animal-based proteins.
  • Complete proteins — they contain all the amino acids your body needs.
  • Excellent sources of calcium.
  • Found in dairy milk.

The main difference is that casein is a slower-digesting protein than whey. “Casein forms a gel-like substance in your stomach,” Homan explains. “It releases more slowly than other proteins and takes longer for your body to absorb.”

Casein protein benefits

Getting the recommended daily amount of protein helps you stay healthy. But casein’s slow absorption also gives it some added advantages. The health benefits of casein include:

1. Gives you all the essential amino acids

Amino acids combine to form proteins. There are 20 amino acids that your body needs to work correctly, and they join in various ways to create different proteins.

Your body makes some of the amino acids it needs, but there are nine essential amino acids that your body can’t produce — you must get them from food. Casein is a complete protein and has all nine essential amino acids.

2. Reduces muscle breakdown

Your cells rely on regular “feedings” of amino acids to continually make proteins. When you go without eating overnight or during an extended fast, your cells may not get the needed amino acids. As a result, they look for those amino acids elsewhere and break down your body’s muscles to get them.

As a slow-release protein, casein provides your cells with the amino acids they need over a long period. The slow absorption consistently feeds your cells with amino acids, allowing muscles to recover instead of breaking down.

3. Promotes muscle growth

Casein contains a high amount of leucine, an amino acid that regulates metabolism (how your body changes food into energy) and helps build and repair muscles. If you don’t typically consume a lot of protein, adding more leucine-heavy protein to your diet (like casein) can help your muscles grow when also engaging in regular exercise.

4. Provides a good source of calcium

The casein in milk is a good source of calcium, which is essential for teeth and bone health. Not getting enough calcium can lead to a loss of bone mass and increase your risk of osteoporosis (a disease that weakens your bones).

Casein protein powder may contain up to 50% of your recommended calcium intake — but always check the label to make sure that the protein powder is a good source of calcium.

How casein protein powder can help

Casein protein’s general health benefits are good for everyone. But using casein protein powder ensures you’ll get a more significant amount of casein each day. Talk to your healthcare provider about taking casein protein powder for:

Weight loss

high-protein diet can help you shed excess pounds and maintain a healthy weight. Protein can help you feel full and improve your satisfaction after the meal.

Different types of proteins affect you differently after you eat them:

  • Whey protein, which you absorb quickly, makes you feel full immediately after ingesting it.
  • Casein’s slow rate of release helps you feel fuller longer.

One study found that participants who consumed casein protein powder before a meal ate less at that meal than people who had whey protein, egg albumin (made from egg whites) or water alone.

“Our bodies only absorb so much protein at one time,” Homan clarifies. “About 30 grams of protein per meal is a good amount to consume. If you plan to have more than one serving of casein powder daily, space it out.” It may help you stave off cravings and decrease snacking between meals, too.

Overnight muscle growth and recovery

Bodybuilders and athletes know that protein is key for building muscle. But keeping your body’s protein levels up overnight can be challenging. That is, unless you ingest casein immediately before going to sleep.

Research shows that consuming casein protein before bed balances your body’s protein level throughout the night. When your protein level stays consistent, muscles can continue to grow and recover — even though you’re not eating.

What to consider before taking casein

For most people, casein doesn’t cause any side effects. But Homan says certain people may need to avoid or limit casein if they have a condition such as:

Casein allergy

If you have a milk allergy, the proteins in milk trigger your immune system and cause it to overreact. People with a milk allergy are allergic to casein, whey or both.

A severe allergy can cause anaphylaxis. More mild symptoms of a milk allergy include:

“Casein allergies are not as common in adults as in children, but they do exist,” notes Homan. If you suspect you have a milk allergy, an allergist can do a test to figure out what you’re allergic to.

Lactose intolerance

Like all dairy products, casein contains the sugar lactose. If you have lactose intolerance, your small intestine can’t digest milk sugar. When you have dairy products, you may develop symptoms including:

“Casein supplements do have lower amounts of lactose,” Homan states. “If you’d like to include casein in your diet but have a lactose sensitivity, the supplement might not trigger it. Talk to your healthcare provider if you’re interested in taking a supplement.”

Protein restrictions

People with kidney disease often need to limit their protein. Too much protein can cause too much waste in your blood. If your kidneys can’t remove the waste, the buildup of toxins can lead to serious health complications.

“People with a protein restriction, such as those with kidney disease, don’t have to avoid casein,” Homan says. “But they do need to watch how much total protein they eat. Your healthcare provider can help you figure out the right amount.”

Sources of casein protein

There are two ways you can add casein to your diet:

Casein supplements

A powdered casein supplement can help you get high amounts of it, according to Homan. The most common form of casein powder is micellar casein, or you can get a rapidly absorbing type (casein hydrolysate). One serving typically contains 24 to 27 grams of protein. Mix with water to create a protein shake, or add it to smoothies, yogurt or baked goods.

“People looking to build muscle or get more protein in their diet should talk to their healthcare provider about adding casein,” she adds. “Supplementing with casein isn’t necessary if you have a healthy, balanced diet, but it can be helpful for some people.”

The U.S. Food and Drug Administration doesn’t regulate supplements. So, it’s a good idea to look for a casein supplement that underwent third-party testing. It’s usually a sign of a higher quality product.

Casein food sources

Anyone can benefit from casein, and you and your family probably already get it from the dairy products you consume, such as:

  • Butter.
  • Cheese.
  • Ghee.
  • Ice cream.
  • Infant formula.
  • Milk.
  • Yogurt.

“Adding a dairy product to your breakfast is an easy way to get some casein every day,” Homan encourages. One glass of milk has 8 grams of protein — 6.4 grams (80%) of that protein is casein. “It’s great to start your day with a good protein source.”FACEBOOK

Colorful fruits and vegetables are packed with phytonutrients that help calm inflammation — by Tamara Soerense @MayoClinic

Can eating the rainbow help to reduce inflammation?

11/6/2025 by Tamara Soerense

nFruitRainbow

Inflammation is a natural process initiated by the immune system in response to illness, trauma, toxins, physical stress and chronic disease. While acute inflammation is protective and allows our bodies to heal, it can become harmful if it persists, leading to chronic inflammation. Chronic inflammation, in turn, can lead to conditions such as arthritis, heart disease, and diabetes.

Several foods can contribute to inflammation. These include highly processed foods, refined carbohydrates, or foods high in added sugars. Conversely, other foods can help calm the immune system, decreasing inflammation.

Let’s explore which foods help lower inflammation and how they can be incorporated into an anti-inflammatory diet.

  • Fruits and Vegetables: Colorful fruits and vegetables naturally contain various phytonutrients and bioactive compounds that help keep inflammation in check. These foods form the foundation of the anti-inflammatory diet and can be enjoyed in abundance. For an extra boost of protection, try drizzling antioxidant-rich olive oil on your veggies..
  • Protein: Choose primarily from plant-based sources such as legumes, soy, nuts, and seeds, with smaller amounts from lean cuts of animal protein and fatty fish. The fats in these proteins, mainly monounsaturated and omega-3, play a significant role in combating inflammation. The American Heart Association recommends 6 to 8 ounces of fatty fish and 5 ounces of legumes, nuts, and seeds per week.
  • Whole grains: Whole grains contain all parts of the grain, whereas refined grains remove the germ and bran, eliminating important inflammation-reducing compounds. Of these, fiber is a bit of a superstar, shown to help reduce blood sugar and cholesterol levels. Aim for at least 50% of your grains from whole grain sources, such as rolled oats and brown rice.
  • Herbs and Spices: Herbs and spices add flavor to your food and help reduce oxidative stress, which can trigger inflammation. Add ginger, turmeric, clove, cinnamon, oregano, and garlic to your next meal.

What change can you make today to shift your body into a less inflamed state?

Consider adding one colorful fruit or vegetable to your diet each day. Suggestions include tomatoes, oranges, yellow bell peppers, arugula, blueberries, pumpkin and broccoli.

Recipe: Spanish Omelet With Veggies and Cheese

Omelets are a great choice for a one-skillet meal, and our recipe delivers on nutrition and taste! This meatless dinner option provides 100% of your daily vitamin C and is a good source of calcium.

Ingredients

  • 5 small potatoes, sliced
  • Vegetable cooking spray
  • 1/2 medium onion, minced
  • 1 small zucchini, sliced
  • 1 1/2 cups green/red peppers, sliced thin
  • 5 medium mushrooms, sliced
  • 3 whole eggs, beaten
  • 5 egg whites, beaten
  • 1/4 teaspoon pepper
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon oregano
  • 3 ounces shredded part-skim low-fat mozzarella cheese
  • 1 tbsp grated Parmesan cheese

Directions

  1. Preheat oven to 375 F.
  2. Cook potatoes in boiling water until tender, about 12 minutes.
  3. In a nonstick pan, add vegetable spray and warm at medium heat.
  4. Add onion and sauté until brown. Add vegetables and sauté until tender but not brown.
  5. In a medium mixing bowl, slightly beat eggs and egg whites, pepper, garlic powder, oregano and low-fat mozzarella cheese. Stir egg-cheese mixture into the cooked vegetables.
  6. In a 10-inch pie pan or ovenproof skillet, add vegetable spray and transfer potatoes and egg mixture to pan. Sprinkle with low-fat parmesan cheese and bake until firm and brown on top, about 20 to 30 minutes.
  7. Remove omelet from oven, cool for 10 minutes, and cut into five pieces.

Ingredient health benefits

  • Potatoes: Don’t let their higher carb and caloric content scare you; in moderation, these starchy vegetables are delicious and nutritious. Potatoes are full of vitamins and minerals like vitamin C , which boosts your immune system, and vitamin B6, which suppresses inflammation and promotes brain health. To get the most out of your potatoes, cook them with the skin on.
  • Onions: This allium is more famous for its potent aroma than its health perks, but rest assured, there are plenty to go around. For instance, onions have chemicals called flavonoids that fight inflammation and help lower blood pressure. And in addition to being a good source of fiber, onions contain prebiotics, which feeds the good bacteria in your gut so they can keep your whole body healthy.
  • Zucchini: If you’re looking for foods with head-to-toe benefits, consider adding squashes like zucchini to your diet. Nutritional highlights include calciumvitamin A and vitamin C — all of which support strong bones and healthy eyes. Squashes are also a good plant source of iron, which keeps your blood cells happy.
  • Red bell peppers: These members of the nightshade family are an excellent, nutrient-dense addition to any meal. Red bell peppers are chock full of vitamins like vitamin E and vitamin B9 (folate). They also contain anthocyanins, which are natural plant pigments that protect your heart, help lower your blood pressure and might support your brain function.
  • Mushrooms: Though these fungi may be small, they’re a mighty culinary ingredient. Mushrooms are full of antioxidants, which help protect your cells from damage by free radicals. And they have compounds that stimulate your immune system to fight invaders and, potentially, cancer. Other properties found in mushrooms also support the health of your heart, gut and brain!
  • Eggs: A perfect example of how good things come in small, oval-shaped packages. Eggs are rich in vitamins like vitamin B12, which is essential for your blood cells and nerve cells to work properly. Eggs also have lutein, a carotenoid that helps preserve your vision. Egg whites have about 60% of the protein found in an egg.

Heavy Alcohol Use Linked to Earlier, More Severe Strokes, Mass General Researchers Find

Alcohol bottles in Broadway Marketplace.

November 17, 2025

Heavy alcohol consumption may lead to earlier and more severe brain bleeds, according to a study published by researchers at Massachusetts General Brigham earlier this month.

Using data from patients admitted to MGB between 2003 and 2019 who had brain bleeds, the researchers found that people who drank heavily — defined as three or more alcoholic drinks a day — were 11 years younger, on average, when their bleeds occurred.

Strokes can be categorized into two types: ischemic strokes, which occur when blood flow to the brain is blocked, and hemorrhagic strokes, which result from a ruptured blood vessel. The researchers focused on the latter, which typically lead to more severe damage.

“Hemhorrhagic strokes, or brain bleeds, are less common, but they are a lot more dangerous,” said Edip Gurol, an associate professor of neurology at Harvard Medical School and author of the study. “50 percent of people who have a brain bleed die within the first month.”

The study, published in Neurology, tracked 1,600 patients over the course of 16 years, of which seven percent reported heavy alcohol consumption. The median age of brain bleeds for heavy drinkers was 64, compared to 75 in those who did not report heavy alcohol consumption.

“There was a very, very significant difference, which is telling us that one way or the other, heavy drinking is accelerating the brain bleeds,” Gurol said.

Using CT scans to determine the size and location of bleeds, the authors found that heavy drinkers experienced 70 percent larger bleeds and were twice as likely to have a bleed deep inside their brain.

“The brain bleeds in those patients were more likely to be deep and more likely to open inside the spinal fluid-filled spaces, the ventricles of the brain,” Gurol said.

Patients who reported heavy alcohol usage had higher blood pressure and lower blood platelet counts when they were admitted to the hospital, the study found. Those patients also showed greater evidence of small vessel damage in the brain, which is linked to several other health conditions such as dementia and heart failure.

“Despite their younger age, very probably because of the excessive alcohol use, these people had more severe small vessel disease-related brain damage, which is called white matter disease,” Gurol said.

Alvin S. Das, an assistant professor at Beth Israel Deaconess Medical Center, said the finding that heavy drinkers experienced larger brain bleeds would prompt him to stress the importance of cutting back on alcohol to his patients.

“What it might compel me to do is in a patient that comes to my office and they’ve had a deep hemorrhage, not only counsel them on aggressive hypertension management down the road to prevent another hemorrhage, but this study also would push me to counsel alcohol cessation,” Das said.

Because the number of heavy drinkers in the study was small and the data came from a single hospital, the researchers noted that future work should use larger datasets to examine how varying levels of alcohol use affect brain aging and stroke risk.

Gurol, for his part, said the findings underscore the importance of limiting alcohol consumption broadly, even in individuals without pre-existing health conditions.

“Even for people without known risk of alcohol damage, it is probably best to not to exceed three glasses per week and not to exceed one glass in over 24 hours,” Gurol said.
