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! @ClevelandClinic

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

A 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

Take a fresh look at oatmeal – it’s not as simple as you think @American_Heart

Oats and oatmeal have powers you probably didn’t know about — like nutrients to help lower cholesterol and enough fiber to help you feel fuller longer. They just might be quiet heroes of #BetterBreakfastMonth.

(Arx0nt/Moment via Getty Images)

By Michael Merschel, American Heart Association News

Let’s admit it: Oatmeal is a total nerd. It lacks fashion sense – the color they named after it is somewhere on the drab side of beige. It’s often seen with Sesame Street’s Bert, who also loves bottle caps, paper clips and pigeons.

But when it comes to healthy eating, oatmeal and the oats it comes from can definitely hang with the cool kids at the breakfast table.

“It has many, many good qualities,” said Candida Rebello, director of the nutrition and chronic disease research program at Louisiana State University’s Pennington Biomedical Research Center in Baton Rouge.

Extensive studies have associated oats and oatmeal with plenty of heart-healthy benefits, such as lowering cholesterol (both total and “bad” LDL cholesterol) and helping with weight control.

Oatmeal has a host of vitamins and minerals. Two examples: According to the U.S. Department of Agriculture, a one-cup serving of cooked oatmeal has about 1.8 milligrams of vitamin B1, or thiamin. That’s close to 15% of what an adult needs each day. It also has 1.36 mg of manganese, which is 59% of the daily recommendation for men and 76% for women. Manganese has roles in immunity, blood clotting and the way cholesterol and blood sugar are metabolized.

But that’s not what makes oats stand out, Rebello said. That same cup of cooked oatmeal has just 166 calories and nearly 4 grams of dietary fiber.

And the type of fiber is where oats start to distinguish themselves. It’s called beta-glucan. Put that in the conversation, and it’s like the scene in a movie where oatmeal takes off its glasses and everyone realizes just how beautiful it is.

Not literally. It’s a soluble fiber, which means it dissolves in hot water, where it thickens. “When you eat oatmeal, the kind of sliminess that you see – that comes from this viscosity that beta-glucan generates,” Rebello said.

That helps you feel full longer, she said. And it helps undigested food travel farther down your digestive tract, where it feeds the friendly bacteria living there.

Beta-glucan is abundant in oats and barley and has been shown “quite unequivocally” to help maintain healthy cholesterol levels, Rebello said.

Oats also are rich phytonutrients – plant-derived substances that may boost health. One class of such phytonutrients is avenanthramides, which are found only in oats. Avenanthramides may have antioxidant and anti-inflammatory effects, although Rebello said their possible benefits are not as well-researched as those for beta-glucans.

Oats have been linked to heart-health benefits since the 1960s and come in many forms. The differences involve levels of processing.

Oats grow in an inedible casing called a hull. Inside the hull is a seedlike groat. That groat is encased in bran. “In other whole grains, like in wheat, you can remove that bran layer,” Rebello said. “But in oats, this groat is very soft, so that bran layer cannot really be removed.”

That means oats are almost always a whole-grain food, and those are a key part of a healthy eating pattern.

If oats are labeled “steel cut,” it simply means they were processed with a steel cutter, Rebello said. Rolled oats are steamed first, then pressed with a roller. “If the roller crushes it into thinner flake, then you get quick-cooking oats,” she said. “If it is then rolled into an even thinner flake, you get your instant oats.”

Rebello said that nutritionally, there is little difference between steel cut and rolled oats. Instant oats, however, have a higher glycemic index, meaning they raise your blood sugar faster.

When oats are ground to flour, the coarser portion is extracted and called oat bran. The beta-glucans will be concentrated in the flour rather than the bran, she said.

Oat milk is derived from oats and water, but processing may add ingredients such as sugar, salt, oil and more. Oat milk has some dietary fiber, Rebello said – commonly 2 grams per cup – but the amount of beta-glucan is rather small.

Unfortunately, Rebello ruled out sugar-filled oatmeal cookies as a healthy food (although she’s not averse to having one as a treat now and then).

How, then, to embrace oats? “Just eat regular oatmeal,” she said. Half a cup of rolled oats cooks up quickly and will keep you full a long time.

Oatmeal with your favorite fruit can be a sweet way to start the day. Cook it in low-fat milk for creaminess and add unsalted nuts to bolster its heart-health value. If you’re time-pressed in the morning, try a healthy version of overnight oats, which can be prepared the night before.

It’s important to remember that no single food, even oats, can do it all, Rebello said, noting that if you eat a nutritious breakfast but then load up on sugar and fat the rest of the day, “that’s really not going to help you much.”

But you should go ahead and invite oatmeal into your breakfast club, Rebello said. “I definitely recommend eating oats.”

All the Reasons You Should Eat Strawberries. @ClevelandClinic #healthaware

Strawberries are an iconic summer fruit — delicious in lemonade, on shortcakes or just straight out of the basket. And it turns out they may be the sweetest way to stay healthy, too. Registered dietitian Bailey Flora, MS, RDN, LD, explains the benefits of strawberries and what nutrients they contain that make strawberries so good for you.

Why are strawberries good for you?

“Strawberries give you a lot of nutritional value for very few calories,” says Flora. “They’re tasty but naturally low in sugar. That’s a combination that’s hard to beat.”

For starters, strawberries are loaded with vitamin C. Eight medium strawberries contain 160% of your daily recommended amount — the amount that the U.S. Food and Drug Administration (FDA) recommends you eat every day. That’s more vitamin C than you get from an orange, the fruit famous for its vitamin C.  

Strawberries are also packed with antioxidants, which protect cells from damage. The primary antioxidant in strawberries is anthocyanin, which gives the fruit its color. The amount of anthocyanin in strawberries increases as the fruit ripens. So, the redder the berry, the more antioxidants it contains.

Strawberries also have fiber and several other important vitamins and minerals, including manganese, potassium and folic acid. And strawberries have less natural sugar than other popular fruits such as apples and bananas.

Health benefits of strawberries

Strawberries are a nutrient-rich snack that can:

1. Boosts brain power

As your brain ages, it can lose some of its mental sharpness. But according to research, eating strawberries protects your brain’s processing powers as you get older.

The Nurses’ Health Study measured brain function in more than 16,000 participants over six years. It found that people who ate the most blueberries and strawberries had less cognitive decline — their thinking and processing abilities didn’t weaken as much. They had the brain power of someone up to two and a half years younger.

In more good news for strawberry lovers: The results of the Rush Memory and Aging Project showed that people who ate strawberries were 34% less likely to develop Alzheimer’s disease.

Researchers believe the protective effects are due to the antioxidants that safeguard cells. Some of the antioxidants in strawberries also reduce systemic inflammation, when your body is in a state of constant inflammation (swelling and irritation). Systemic inflammation is a key factor in the development of Alzheimer’s disease.

2. Strengthens your immune system

Strawberries are a great source of vitamin C (ascorbic acid), which you need to get from food, as your body can’t produce it. In rare cases, people who don’t get enough of this crucial vitamin develop scurvy, a disease that causes bleeding, bruising and anemia.

Vitamin C plays an important role in wound healing. And it may prevent and treat respiratory and systemic infections too. Research shows that vitamin C increases the production of:

  • T-cells, which remove infected and cancerous cells.
  • B-cells, which create antibodies so your body can better defend against germs in the future.

Vitamin C is also anti-inflammatory, lowering your stress response triggered by illness or just your busy life. To ward off germs, researchers suggest getting 100 to 200 milligrams (mg) of vitamin C a day — and more when you’re sick. As eating eight medium strawberries gives you 160 mg, it takes just a handful of berries to help keep your immune system in good shape.

“There isn’t enough evidence to say whether vitamin C can prevent colds and the flu,” says Flora. “And it can be more beneficial to choose vitamin-C-rich foods like strawberries over vitamin C supplements, as you get additional health benefits. With strawberries, that includes fiber and other phytonutrients and vitamins that cannot be replicated in a vitamin supplement.”

3. Protects heart health

Flora says that popping a few strawberries in your mouth isn’t just a way to stave off hunger — it’s also a heart-healthy food choice. Research shows that strawberries can help prevent several conditions that can lead to heart disease and stroke, as well as diabetes, which increases the likelihood of heart disease. Eating more strawberries can help you:

Lower cholesterol

In one small study, participants consumed two drinks a day, each made with 25 milligrams of freeze-dried strawberry powder blended with water. That’s about the same as eating 3.5 cups of fresh strawberries a day. After a month, the participants’ total cholesterol was 5% lower.

The cholesterol-lowering results of that study were echoed in another study that gave participants the same amount of freeze-dried strawberry powder. But this time, they consumed the drink for two months. Researchers compared the results to a group that just drank more water. Those who sipped the strawberry drink saw their cholesterol decrease by 10%.

Decrease triglycerides

Triglycerides are fats found in your blood. Having high triglycerides increases your risk of heart disease. And when triglycerides break down, they leave byproducts that trigger inflammation, attracting sticky deposits to blood-vessel walls. That material can clog your arteries (atherosclerosis), explains Flora.

But eating a pound of strawberries a day may reduce triglycerides by 20%. That’s the result of one study, which also found that strawberries reduced total cholesterol by 8%. 

4. Reduces inflammation

Widespread internal inflammation contributes to multiple diseases, including heart disease. Lifestyle factors like a poor diet, low physical activity and smoking can lead to inflammation.

Eating more strawberries is a step in the right direction to boost your heart health, says Flora. That’s because the most prevalent antioxidants in strawberries are anthocyanins, known for their anti-inflammatory effects.

5.  Helps manage blood sugar

Too much glucose (sugar in your blood) is a risk factor for Type 2 diabetes, making you more likely to develop heart disease, too. If you’re watching your blood sugar levels, strawberries are a good way to satisfy your sweet tooth.

In a Finnish study, people who ate strawberries with a piece of white bread released 26% less insulin compared with eating bread with a cucumber. Participants also ate the bread with other berries, including raspberries and cranberries. Only strawberries weakened the post-meal blood sugar spike.

Strawberries are a great addition to a healthy diet, especially when you eat them on their own — Flora advises laying off the calorie-laden whipped cream, cake or ice cream. (Sorry!) They’re delicious, full of good-for-you nutrients and low in sugar. Try this strawberry smoothie. (Surprise — it’s green!) And for a strawberry treat that’s not too sweet, make these strawberry pretzel squares at your next get-together.FACEBOOKTWITTER

Want to tone your midsection? You can start by standing up to do ab exercises. @ClevelandClinic

Want to tone your midsection? You can start by standing up to do ab exercises.

Surprised? That’s understandable. After all, most of us think of a few classic on-the-floor exercises when it comes to strengthening our abdominals. Crunches and sit-ups, for instance. Planks, too.

But it turns out, you can get a deeper and more thorough core workout while on your feet, says exercise physiologist Katie Lawton, MEd. Here’s how.

Standing ab exercises

The pursuit of “six-pack abs” explains the devotion to crunches and similar floor exercises. “You completely isolate the rectus abdominis muscles when you lie down and do that motion,” says Lawton. “It’s very targeted.”

That’s great for creating washboard abs. But it doesn’t do much to enhance other muscles in your middle that play an important role in day-to-day movements.

Standing ab exercises, on the other hand, engage a network of muscles within your core that you use all the time, whether it’s picking laundry up off the floor or putting cans on the top shelf in the pantry.

“Think of your core as a chain of muscles that needs to work together to get the job done,” illustrates Lawton. “When you do an ab workout from a standing position, you’re working more of the muscles in that system.”

Strengthening your core can help you:

  • Improve your balance
  • Maintain good posture
  • Protect your back from aches and pains
  • Better handle day-to-day movements that require bending, lifting and twisting

Incorporate these exercises in a standing abs workout to see those benefits.

Six standing exercises to strengthen your core

1. March

Muscles targeted: Rectus abdominis, transverse abdominis, erector spinae and hip flexors

  1. Start in a standing position with your feet about hip-width apart.
  2. In an exaggerated marching motion, bring your right knee straight up and move it toward your chest until your thigh is parallel to the floor.
  3. Return to a standing position and repeat the motion with your left leg for one set.
  4. Continue for 10 to 15 sets.

Pro tip: Want to make the march more challenging? Then add a “twist” to your motion by moving your right knee toward your left side when you raise it. (Your left knee would go toward your right side.)

2. Overhead side bend

Muscles targeted: External and internal obliques, quadratus lumborum, deltoids and erector spinae

  1. Stand tall with your feet hip-width apart.
  2. Extend your arms up, palms facing each other (as if you’re signaling a touchdown).
  3. Tilt to the right while keeping your torso and arms straight. You’ll feel a stretch on the left side of your body as your waist bends to the right.
  4. Return to the center position and repeat the motion to the left for one set.
  5. Continue for 10 to 15 sets.

Pro tip: “As you bend to each side, focus on engaging your core muscles to work them properly,” advises Lawton. “You’re just going to the side, too. Your torso shouldn’t lean forward at all.”

3. Standing hip abduction

Muscles targeted: Rectus abdominis, transverse abdominis, erector spinae, glutes and hamstrings

  1. Begin in an upright position with your feet about hip-width apart.
  2. Kick your right leg out to the side, keeping it straight. Your toes should point forward during the motion as your leg scissors out and back. “Keep the movement smooth and consistent both ways,” instructs Lawton.
  3. Repeat 10 to 15 times and then do the same with your left leg.

Pro tip: Use a chair to steady yourself if balance is an issue. “You always want to make sure these exercises are done in the safest way possible,” emphasizes Lawton.

4. Twists

Muscles targeted: Internal and external obliques, rectus abdominis, transverse abdominis and erector spinae

  1. Stand and plant your feet about shoulder-width apart.
  2. Extend your arms straight out in front of you, parallel to the floor.
  3. Rotate your upper body to the right from your midsection while trying to keep your hips facing forward.
  4. Return to the center. Then, rotate to the left to complete one set.
  5. Repeat 10 times.

Pro tip: Twists should be done in a slow and controlled manner. “You don’t want to be whipping back and forth,” cautions Lawton.

5. Crossover toe touch

Muscles targeted: Internal and external obliques, rectus abdominis, transverse abdominis, erector spinae, hamstrings and glutes

  1. Begin in a standing position with your feet slightly wider than shoulder-width apart.
  2. Extend your arms out to your side, as if forming the letter T.
  3. Rotate your torso to the right while reaching your left hand down to tap your right foot. Most of the movement should be in your core, not your legs.
  4. Return to the T position and repeat the motion in the opposite direction (with your right hand touching your left foot) to complete a full set.
  5. Repeat 10 to 15 times.

Pro tip: Skip this exercise if you sometimes get lightheaded when raising your head and up and down.

6. Wood chop

Muscles targeted: Internal and external obliques, rectus abdominis, transverse abdominis, erector spinae, deltoids and latissimus dorsi

  1. Stand with your feet positioned shoulder-width apart.
  2. Clasp your hands together (as if holding an ax) and bring them up over your head to the right. Your torso will rotate slightly to the right as you twist.
  3. Bring your hands down and to the left in a “chopping” motion that swings across your chest toward your left leg. Rotate your torso to the left as you take the swing. Bend your knees slightly and pivot your feet, too.
  4. Return to the raised position. Take 10 chops.
  5. Repeat with your hands, starting to the left and swinging to the right.

Pro tip: Tailor these exercises to your range of motion. “Move the best you can within the parameters you have,” advises Lawton. “When you start to feel that tension in your muscles, stop there. If it hurts, you’ve gone too far.”

Final thoughts

The simplicity of standing ab exercises just … well, stands out. That’s because the exercises build on natural movements that we do all the time. “That’s a big reason why they’re so effective,” says Lawton.

It’s important to safely progress these exercises as they become easier. Resistance bands, cable machines, medicine balls or free weights are all tools that can help you increase the intensity of the movements.

Dedicating a few minutes a day to these exercises can help you build core strength that supports everything you do, from walking the dog to lifting groceries.

“Standing ab exercises really don’t take a lot of time,” emphasizes Lawton.

Plus, you won’t need to find your floor mat to do them.
