Walking even at a “casual” pace five days a week may lower the odds of high blood pressure in postmenopausal women, a new study finds: https://bit.ly/3oyORag #HarvardHealth #WomensHealth

You know exercise builds muscles, strengthens bones, keeps your heart healthy and your mind sharp. But it also does something that you might not think much about: It helps keep your immune system — your internal defenses against infection — in tip-top shape.
If you take time for some physical exertion each day, it helps get your body ready to attack bacteria, viruses and toxins that can sneak in and make you sick.
But how much exercise is effective? Do too little or too much, and it won’t have the best effect on your immune system.
Clinical immunologist Leonard Calabrese, DO, answers common questions about how exercise can impact your immunity and how to use your workouts to shut out a world of would-be invaders.
A: If you exercise moderately on a regular basis, it tunes up the immune system in many ways. It enhances your broad-based defenses against viral infections, such as those causing upper respiratory infections.
Working out regularly also reduces the risk of many chronic diseases such as cardiovascular, respiratory illnesses and metabolic diseases, such as type 2 diabetes.
A: Fortunately, you don’t have to push yourself to the limit to rev up your immune system. In fact, your immune system needs less of a workout than you get with your average cardio routine.
Focus on getting 20-30 minutes of moderate exercise, five days a week, and your immune system will thank you.
A: Moderate exercises, including biking or walking briskly in your neighborhood, are good ways to get your blood flowing. Swimming is also a good option for non-weight-bearing exercise for your joints.
Also try mind-body exercises such as Tai-Chi, Qi Gong and yoga, which are all options that help keep your joints flexible. These exercises also reduce chronic stress, which in itself is a powerful immune booster. These exercises can also help alleviate osteoarthritis and fibromyalgia symptoms.
A: Yes, though, the level to which it can slow your system down is still up for debate.
Research shows that exercising for more than 1.5 hours without refueling your body or giving it enough time to recover suppresses your immune responses for up to a few days. During that time, your cortisol levels rise, your white blood cell count drops and you’re more likely to develop a respiratory infection.
This problem usually affects elite athletes, such as marathon runners, most.
On the flip side, staying sedentary also increases your risk of infection, inflammation and chronic disease.
A: Yes, it can. This is a complex issue, but I like to tell my patients to do a “neck check.” If your symptoms are mostly of a mild cold without fever or lower respiratory symptoms, such as a productive cough, wheezing or shortness of breath, mild exercise can actually reduce congestion and may make you feel better.
If your symptoms are primarily in your lungs or you have a significant fever its better to rest until things settle down. Regardless, good hydration is important.

This dairy product can help you lose weight, manage blood sugar and strengthen bones
Cottage cheese doesn’t typically receive a lot of attention. It gets left out from the fancy cheese counter at the grocery store. It doesn’t make the cut for a charcuterie (meat and cheese) board. And it isn’t typically included in recipes for favorite foods such as pizza, grilled cheese or baked ziti.
It’s a soft, white, fresh cheese that’s different in texture and taste than more popular cheddar, Parmesan and blue cheeses. But cottage cheese holds a prominent place in the dairy aisle for good reasons, says registered dietitian Julia Zumpano, RD, LD.
“It’s a portable food that’s easy to add to your diet,” she says. “And cottage cheese offers lots of health benefits.”
As a dairy product, cottage cheese is a great calcium source, which is important for bone health. Having healthier bones makes you less likely to get osteoporosis (weak bones). Cottage cheese in your diet can even help with your blood sugar levels.
Thinking about giving cottage cheese a go? Zumpano explains what you need to know.
Cottage cheese is low in calories while providing protein and vital nutrients, Zumpano says, making it one of the healthiest cheeses you can eat. It’s made by curdling pasteurized (sterilized) cow’s milk — when milk turns acidic, the milk protein separates and forms curds (clumps). These loose curds serve as the base for cottage cheese.
Depending on the fat content of curdled dairy milk, cottage cheese is available as nonfat, low fat (1% or 2%) or whole fat. The milk type affects the nutritional content.
“To get the most bang for your buck, choose a low-fat or even full-fat cottage cheese,” Zumpano advises. “Nonfat cottage cheese may sound like a good idea, but it contains less protein and won’t be as satisfying.” Full-fat cottage has 1.5 grams more of saturated fat when compared to 2% but can be the most satisfying.
Cottage cheese may be mild in flavor, but it packs a punch when it comes to potential health benefits. Some of the many benefits of cottage cheese include:
A 100-gram serving (just under a half cup) of low-fat (2%) cottage cheese provides:

Three factors make cottage cheese a great choice if you’re looking to lose pounds or maintain your weight:
Cottage cheese isn’t the only dairy food to provide these advantages. Greek yogurt can also check these boxes. But if you’re deciding between the two, Zumpano recommends cottage cheese. “Full-fat cottage cheese and full-fat Greek yogurt have the same amount of fat, but cottage cheese has 25% more protein.”
Cottage cheese is rich in casein (pronounced “KAY-seen”) protein. It’s a complete protein that provides essential amino acids, which are all the building blocks of protein that your body needs.
Amino acids help your body work smoothly. They affect your:
“Eating cottage cheese as part of a balanced diet is an easy way to ensure your body gets everything it needs,” says Zumpano.
Cottage cheese has three nutrients that help promote healthy bones:
“Bone health is critical as you age,” Zumpano shares. “Adding cottage cheese to your diet is an easy way to strengthen them.”
Plain cottage cheese is low in carbohydrates, making it a great option for anyone watching their blood sugar. The slow-digesting casein protein in cottage cheese also helps prevent blood sugar spikes.
“To get this benefit of cottage cheese, choose plain cottage cheese,” Zumpano recommends. “Avoid cottage cheese pre-packaged with fruit and check the label for added sugar.”
Probiotics are live microorganisms that can improve the balance of good and bad bacteria in your gut (gut microbiota). The curdling process used to produce cottage cheese adds beneficial bacteria that can promote better gut health. But unlike Greek and regular yogurt, which almost always contain probiotics, not all cottage cheese is created equal.
“If you want cottage cheese that provides probiotics,” Zumpano says, “check the label to see if it says it contains ‘live and active cultures.’”
The slow-release protein in cottage cheese doesn’t just help with digestion. It’s also important for building muscle tissue and helping your muscles recover after a workout.
“Casein protein provides your cells with amino acids consistently over a longer period, which helps muscles recover instead of breaking down,” Zumpano explains. Consider having cottage cheese after a workout to get the maximum benefit for your muscles.
Research shows that increasing dairy intake may lower your risk for some (though not all) cancers. “There’s still a lot to learn about the connection between dairy and cancer prevention,” Zumpano states. “But it’s clear there are protective benefits to including dairy in a balanced diet.”
Experts believe getting more calcium may offer protection from:
The United States Department of Agriculture (USDA) recommends that adults get three cups of dairy daily. Cottage cheese can help you reach that goal.
When you incorporate cottage cheese into your diet, remember to:

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.”

You likely know that drinking alcohol too often or to excess isn’t a good idea, health-wise. But when it comes to alcohol and heart health, you may have heard different sides. Is drinking all that bad for your heart? Can a glass of wine help reduce your risk of heart disease — or make it worse?
First things first: If you drink alcohol, you should do so in moderation to avoid alcohol-related heart issues. And you should never intentionally use alcohol to try to reduce your risk of heart disease.
To further explore the relationship between your ticker and your favorite glass of merlot or IPA, we chatted with cardiologist Leslie Cho, MD.
Here are some of the effects of alcohol on your heart:
One of the most important things your heart does is keep a rhythm. On average, a regular heart rate is about 60 to 100 beats per minute when your body is at rest. But alcohol can lead to your heart rate temporarily jumping up in speed, and if it goes over 100 beats per minute, it can cause a condition called tachycardia. Too many episodes of tachycardia could lead to more serious issues like heart failure or going into irregular rhythms, which can cause heart attack and stroke.
That fourth drink at the bar may feel like it’s relaxing you, but it’s actually affecting your body differently than you might think. Alcohol can affect your blood pressure, causing it to go up temporarily. This is especially true when you engage in binge drinking (that’s defined as four or more drinks within two hours for women and people assigned female at birth, and five or more drinks within two hours for men and people assigned male at birth).
And sure, we’ve all had a night here or there where we’ve had one too many and we know it. But it’s important to make sure those nights of overindulgence are the exception and not the rule. If you’re not sure, make a note to tune into how much you’re having over the course of the next month or so. If it’s more than recommended, try to consciously pace your drinking to help reduce the spike in your blood pressure that excessive alcohol causes.
And if you have a history of high blood pressure, it’s best to avoid alcohol completely or drink only occasionally, and in moderation.
Whether it’s a glass of red wine with your turkey or toasting champagne for the new year, alcohol definitely becomes more present during the holiday season. And while enjoying celebratory spirits in moderation is alright for most people, it’s important to be aware you can fall victim to holiday heart syndrome if you overdo it. This is when overeating and overindulging in alcohol lead to an irregular heartbeat.
Holiday heart syndrome can happen if you don’t typically drink alcohol, but then have a few at a holiday party or if you binge drink. This can cause you to develop an irregular heartbeat, called atrial fibrillation, which can increase your risk of stroke, heart attack and heart failure.
The short-term effects of alcohol (headache, nausea, you know the rest) are easy to pinpoint. But there are ways that alcohol affects your body over time that are important to understand. One of the long-term effects of alcohol on your heart is alcoholic cardiomyopathy. This is when your heart-pumping function gets weaker and your heart gets larger due to changes from heavy alcohol use over a long period of time.
OK, don’t panic. If you’re an occasional drinker, there’s no cause for worry. But it may be worthwhile learning about what counts as binge drinking and whether or not you may be drinking too much and don’t even know it.
It’s true, red wine is a better choice than hard liquor. But can a trip to the wine bar boost your heart health?
You should never consider wine or any other alcohol as a way to lower your heart disease risk. And, in fact, the study also showed that drinking one or fewer drinks per day was related to the lowest likelihood of dying from a stroke. However, Dr. Cho points out that more recent data shows that there may be no amount of alcohol that is truly safe. “The myth that wine is beneficial for heart health is no longer true,” she states.
“It’s not a good idea to start drinking alcohol in an effort to lower your risk of heart disease,” Dr. Cho continues. “It’s better not to drink any alcohol at all.”
The American Heart Association recommends the same.
It’s also important to know that the ways in which alcohol affects your heart will vary from person to person, depending on your age and other conditions you may have.
Let’s face it, a hangover in your mid-40s doesn’t feel the same as one in your early 20s. This is because your age plays a factor in how well you tolerate alcohol. While some people develop a tolerance to alcohol over time, this isn’t true for everyone — and this ability doesn’t last forever, Dr. Cho notes.
“As we get older, our ability to clear alcohol definitely decreases and our sensitivity to alcohol probably increases,” she explains. “Also as we get older, we end up having more diseases, so we could be on medicines that can interfere with the way our bodies metabolize alcohol.”
In many ways, your medical history (and present) can tell you a lot about your future with alcohol. That means, if you’re living with other medical conditions and/or taking certain medications, this will all have an impact on how alcohol affects you.
“Certain health conditions can make drinking alcohol more dangerous,” Dr. Cho says.
For example, some people who are on cholesterol-lowering medicines may experience muscle aches when they drink alcohol. Because alcohol and cholesterol medicine both are processed through your liver, they are, in a sense, competing for clearance. So, it’s important to think about your overall health and talk to a healthcare provider about your personal risk factors.
“Alcohol is made out of sugar,” Dr. Cho points out. “So, if you’re predisposed to diabetes or if high triglycerides are one of your issues, it’s not a good idea to drink alcohol.”
Dr. Cho also warns that if you have liver dysfunction or take other medicines that are processed through the liver, your risks might be different. Talk to your healthcare provider about how alcohol might interact with your prescription medicines.
The last thing you want is for that casual drink after work or glass of wine at dinner to negatively impact your heart health. There’s a way to have a healthy, balanced relationship with alcohol that lets you enjoy a drink occasionally and celebrate with friends and family. But your heart is an important organ that should also be cared for, so be sure to drink in moderation, learn about binge drinking and know what your body can (and can’t) tolerate before opening that tab.FACEBOOKTWITTERLINKEDINPINTERESTEmailalcoholalcohol and healthalcoholic beveragesbinge drinkingheart health
