health benefits of coffee

Coffee Scores Another Win for Improving Health

, , , , , , Health Basics, Healthy Living, Lifestyle, Nutrition, Preventative Health

Besides water, our primary care concierge doctors in Jupiter are hard-pressed to think of another beverage that offers such a wide range of health benefits as coffee.

For example, research has found that regular coffee consumption has been linked to a lower risk of: 

  • heart disease and strokes
  • heart failure
  • melanoma
  • diabetes
  • liver and prostate cancer
  • Parkinson’s disease

Evidence piles up

Studies have also found that the caffeine in two cups of coffee a day provides significant protection against Alzheimer’s disease, as well as other types of dementia. A study released last year, for example, found that individuals who drank four to six cups of coffee or tea a day reduced their risk of stroke and dementia by 28 percent compared to those who did not drink either beverage.

Another study, published last year in the journal BMC Public Health, found that those who drink three to four cups of coffee a day (whether ground, instant, caffeinated or decaf) reduced their risk of chronic liver disease by 21 percent, compared with those who didn’t drink coffee at all.

A third study, also published last year in the American Heart Association (AHA) journal Circulation, found that drinking one or more cups of plain, caffeinated coffee a day was associated with a long-term reduced risk of heart failure.

The AHA researchers found that the risk of heart failure dropped between five percent and 12 percent for each cup of black coffee the subjects drank. The risk declined even more, to 30 percent, when subjects drank two or more cups daily in one of the studies. The study found, however, that decaffeinated coffee did not offer the same benefit. 

“The association between caffeine and heart failure risk reduction was surprising,” senior author Dr. David Kao, medical director of the Colorado Center for personalized Medicine at the University of Colorado School of Medicine in Aurora, said in a statement.

“Coffee and caffeine are often considered by the general population to be ‘bad’ for the heart because people associate them with palpitations, high blood pressure, etc. The consistent relationship between increasing caffeine consumption and decreasing heart failure risk turns that assumption on its head,” he said.

Latest findings

The most recent research, published last month in the Annals of Internal Medicine, found that people who drink a moderate amount of coffee, defined as up to 3 1/2 cups a day, were up to 36 percent less likely to die from any cause over the seven-year period of the study than those who did not drink coffee.

It didn’t matter what type of coffee the subjects drank—ground, instant, caffeinated, or decaf—or even if they added a modest amount of sugar: The results were the same.

According to Johns Hopkins, there are also many other benefits from daily coffee consumption. For example:

  • Coffee may help your body process glucose better, meaning you may be less likely to develop type 2 diabetes.
  • Coffee may lower the risk of developing Parkinson’s disease, and help those who have it control their movements better.
  • Coffee can help lower your risk of colon cancer.
  • Drinking dark-roast coffee has even been shown to decrease breakage in DNA strands, which helps protect against various cancers.

Some coffee caveats

It’s typical with humans, however, to think that if something is good for you, more of it is better. That’s rarely the case, including with coffee.

The U.S. Department of Agriculture’s (U.S.D.A.) Dietary Guidelines for Americans recommend no more than 400 milligrams of caffeine a day. An average eight-ounce cup contains 95 milligrams of caffeine.

Several studies—including those outlined above—have found that five cups of coffee a day appears to be the upper limit of safety. In fact, a 2009 study found a 17-21 percent increased risk of death among those who drank four or more cups a day.

Other possible negative effects of too much coffee include:

  • increased blood pressure
  • headache
  • heartburn
  • dehydration
  • increased heart rate
  • abnormal heart rhythm
  • anxiety
  • dizziness
  • insomnia

In addition, a 2017 study found that pregnant women who drink more than four cups of coffee a day were more likely to experience low birth rate babies, preterm births, and stillbirths.

Another study linked coffee consumption with the possibility of increased bone loss in postmenopausal women if their diets lack sufficient calcium intake.

Finally, those who are sensitive to caffeine may experience many of these side effects with even small amounts of coffee. Older adults also may not be able to metabolize caffeine as well they did when they were younger.

And anyone who is taking certain drugs (like ephedrine, used in decongestants) can experience increased blood pressure, along with a higher stroke risk, when they consume coffee as well. 

But if you’re not caffeine-sensitive, and you don’t overdo it, our primary care doctors urge you to feel free to enjoy that third or fourth cup of the day without guilt.

is popcorn healthy

In Praise of Popcorn

, , Nutrition

Our concierge doctors in Jupiter sometimes feel bad about all the tasty foods we suggest you avoid if you want to stay healthy. So we thought it would be nice for once if we could bring you some good news about a popular snack food.

When it comes to so-called “junk” foods, popcorn is one you don’t have to feel guilty about: with a couple of caveats, that is, which we’ll explain below. In fact, popcorn prepared the right way is so good for you, it doesn’t even belong on a list that includes cookies, chips, and ice cream.

Tiny Powerhouse

Popcorn by itself is a whole grain that includes the germ, the bran, and the hard outside endosperm. Together these components are packed with nutrients, including protein, vitamin E, several B vitamins, minerals, and healthy oils, along with fiber and antioxidants.

Here are some of the nutrients that popcorn provides:

  • vitamin B6
  • vitamin E
  • vitamin A
  • vitamin K
  • niacin
  • thiamin
  • riboflavin
  • pantothenic acid
  • folate

As an added bonus, it’s also naturally low in calories at just 90 calories. In addition, it’s also very filling due to its protein (three grams per three-cup serving) and high fiber content (three grams per three-cup serving), which can aid in weight loss.

Whole grains are an important component in a healthy diet because they’ve been shown to help reduce the risk of high blood pressure, heart disease, and diabetes. Other benefits that are attributed to whole grains include lower cholesterol levels and improved digestion.

“When prepared well, popcorn is actually a pretty good snack,” Maya Vadiveloo, an assistant professor in the department of nutrition and food sciences at the University of Rhode Island, told the American Heart Association (AHA) News.

“It’s stable. It’s inexpensive. It’s fairly tasty. For people who might be struggling to eat adequate fruits or vegetable or other whole grains, it’s a low-risk snack to start.”

Now for the bad news

Corn was domesticated in Mexico more than 9,000 years ago. And there is some evidence that popcorn has been enjoyed for millennia by people all around the world—anywhere, that is, where corn is a staple of the diet.

Simply heating the kernels causes them to pop, so it’s not surprising that archaeologists have found evidence that early cultures in Central and South America enjoyed this snack. It’s probably safe to say, however, that they didn’t drench their popcorn in melted butter and top it off with handfuls of salt.

And that’s one of the caveats we mentioned above. This wholesome snack food can turn unhealthy pretty quickly when prepared the wrong way, i.e., in microwavable bags, with unhealthy oils, or when loaded up with the wrong toppings.

For example, “Popcorn at the movies is very different than popcorn made at home,” Vadiveloo said. “Even a small movie theater popcorn has significant calories and is very high in salt.

“Sodium is one of the leading risk factors for hypertension [high blood pressure] and stroke in general, so it’s something we do care about from a perspective of heart disease,” she explained, adding that a tub of movie theater popcorn can contain up to 1,090 calories and 2,650 milligrams of sodium.

Keep it healthy

Even if you make it yourself on the stove, however, the oil needed during the cooking process can double the amount of calories, nutritionist Julien Chamoun of RD Nutrition Counseling in New Jersey, tells CNN.

That’s why he recommends an air popper for your popcorn.  Both microwave popcorn and popcorn popped in oil will absorb those oils, so air popping is generally considered the healthiest way to prepare popcorn because it uses no oil at all.

If you don’t want to buy an air popper, however, you can cook it on the stove using healthier oils such as extra virgin olive oil, walnut, avocado, or canola oils, according to the Cleveland Clinic. Avoid palm and coconut oils, because they contain high amounts of saturated fats, and skip corn oil, sunflower oil, and soybean oil entirely.

Mexican pop corn with hot sauce and chili powder

Chamoun recommends this method to make 16 cups (about four servings):

½ cup popcorn kernels

2 tablespoons oil

Pour the oil into a large pot, at least six quarts in volume. Add two or three kernels to the pot, then cover and place over medium-high heat until you hear the kernels pop.

Take the pot off the heat, put in the remaining kernels, and cover the pan. Wait 30 seconds, then return the pot to the burner and cook, shaking the pan frequently to ensure the unpopped kernels fall to the bottom to cook as well as to prevent burning the cooked popcorn, until the popping slows down.

Remove the pan from the burner, lift the lid carefully to allow the steam to escape, then transfer the popcorn to a large bowl. Toss it with a little olive oil or walnut oil to help any toppings stick to the popcorn.

The seasonings you can use are almost limitless, as long as you avoid or at least minimize the usual butter and salt. Try adding garlic powder, onion powder, cinnamon, nuts, paprika, chili flakes, grated cheese, Italian herbs . . . anything you like that’s low in sugar and salt.

When you’re digging into a bowl of rice cereal, or a hearty helping of arroz con pollo, or just munching on low-cal rice cakes, you certainly don’t expect to be ingesting a potential toxin. But unfortunately, that’s what’s happening whenever you or your children consume any type of rice.

Our concierge primary care doctors in Jupiter aren’t telling you to avoid rice altogether. We do think you should know about the risks connected with arsenic in rice, and how to mitigate them.

salt intake

Where All Your Salt Intake comes From

, , , , Nutrition

So many of our patients tell us they never add salt when cooking. So of course, they’re restricting their salt intake.

But if you eat anything processed, packaged, or prepared outside the home, your salt intake is much higher than considered healthy.

Our primary care doctors in Jupiter think you’ll be surprised by how much salt is in your kitchen outside the saltcellar. Manufacturers rely on it to prolong the shelf life of their products. It helps prevent the growth of bacteria and other disease-causing agents.

Are Plant-Based Burgers Healthier?

, , , Healthy Living, Nutrition

Due in part to the pandemic, sales of plant-based foods have soared recently. One survey reported 77 percent of U.S. shoppers bought at least one type of plant-based food in the last six months. Of those, 30 percent said this was a direct result of the COVID-19 pandemic.

Some respondents said they wanted to make a conscious effort to eat healthier to improve their immune systems. Others said it was because they had more time at home to experiment with new food choices.

Our primary care doctors at MD 2.0 in Jupiter certainly applaud this trend. At the same time, we noticed one of the main drivers of plant-based food sales is the meatless burger. You can now find it on grocery store shelves and many restaurants.

So are plant-based burgers healthier than their meat-based inspiration? The answer seems to be, not necessarily.

avocado for health

For Your Overall Health, Consider the Mighty Avocado

Healthy Living, Nutrition

Study after study has shown that the best way to stay healthy is to eat a plant-based diet. That doesn’t necessarily mean strictly vegetarian. Consider a meal plan focused on natural foods, especially plants, and minimal meat, processed foods, and dairy products.

One fruit that our concierge primary care doctors would like to suggest you incorporate into your diet is the avocado. (And yes it is technically a fruit, even though people often think of it as a vegetable.) That’s because there’s a wealth of health-giving nutrients packed into one avocado. From heart health to improved digestion to better eyesight, avocados have long had a reputation as a powerhouse superfood.
