Bananas nature’s perfect snack @ClevelandClinic #therapeutic

Some have called bananas “nature’s perfect snack,” and it’s easy to see why. The curvy yellow fruits come conveniently packaged, travel well in a lunch bag or purse and are incredibly versatile. They make a great smoothie mixer or a tasty topper on cereal or oatmeal and even have their very own category of (delicious!) muffins and bread.

Are bananas healthy?

 “Absolutely,” says registered dietitian Elyse Homan, RD, LD. “They’re full of nutrients and easy on the gut. Very few people have problems digesting bananas.”

So, what are you eating when you peel and enjoy? A medium-sized ripe banana contains:

  • 105 calories.
  • 1 gram of protein.
  • 28 grams of carbohydrates.
  • 15 grams of (natural) sugar.
  • 3 grams of fiber.
  • Less than 1 gram of fat.

Health benefits of eating bananas

From vitamins to minerals to fiber, bananas are good for you, with lots of nutrition to offer. Plus, they’re easy to digest, reiterates Homan. Here’s a breakdown of banana’s most notable nutritional benefits:

1. Fiber for improved digestion and disease prevention

With 3 grams (g) of fiber, a banana supplies nearly 10% of what you need in a day, based on a 2,000-calorie daily diet, according to the U.S. Department of Agriculture (USDA) dietary guidelines.

You hear “fiber” and probably automatically think of digestion. It’s true — fiber is great for your gut. It helps keep things moving in your intestines, and most of us probably need to eat more.

But fiber also impacts your health in other ways. Researchers who looked at data from nearly 200 studies found that people who ate 25 to 29 g of fiber a day had up to a 30% decreased risk of:

  • Colorectal cancer.
  • Heart disease.
  • High blood pressure.
  • High cholesterol.
  • Stroke.
  • Type 2 diabetes.

2. Vitamin C for better immune health

Vitamin C (ascorbic acid) is a nutrient that helps your body absorb iron and boosts your immune system’s ability to fight illness. Adults need 75 to 90 milligrams (mg) per day. A banana delivers about 10 mg of vitamin C.

Vitamin C is one of many antioxidants you can get from food. Antioxidants are important because they cancel out free radicals in your body. Free radicals can build up and damage your cells, leading to disease. But antioxidants like vitamin C keep free radicals in check.

3. Vitamin B6 for improved metabolism and more

Your body needs vitamin B6 for:

  • Appetite regulation.
  • Immune system functions.
  • Metabolic processes.
  • Nervous system health.
  • Sleep regulation.

“One banana will give you one-quarter to one-third of the vitamin B6 you need in a day,” says Homan.

4. Potassium for organ health and lower blood pressure

The USDA recommended daily intake of potassium for adults is 4,700 to 5,000 mg. A banana supplies you with about 422 mg, or a little less than 10% of what you need per day.

Potassium, a mineral, does a lot for your body. It’s essential for the proper function of your:

  • Heart.
  • Kidneys.
  • Muscles.
  • Nerves.

Getting enough potassium also keeps your blood pressure in a healthy range. Potassium, which lowers blood pressure, balances out sodium, which raises blood pressure.

Homan says potassium also benefits your vascular system — the network of blood vessels and lymph vessels that run through your body’s tissues and organs — and reduces your risk of:

  • Heart disease.
  • Kidney failure.
  • Stroke.

5. Magnesium for improved blood pressure, blood sugar and more

A single medium-sized banana offers about 32 mg of the mineral magnesium, which fulfills around 8% to 10% of your daily magnesium requirement.

Magnesium is involved in many processes in your body, including:

  • Blood pressure.
  • Blood sugar levels.
  • Building proteins.
  • Maintaining bone.
  • Muscle function.
  • Nerve function.

Bananas and resistant starch

Green, or unripe, bananas are high in resistant starch. “Your body can’t digest resistant starch,” notes Homan. “Instead, it’s a prebiotic that promotes the growth of good bacteria in your colon.” Prebiotics improve digestive health and can be helpful if you’re experiencing diarrhea.

“I often hear patients say they avoid bananas since they’ve heard the fruit is too high in sugar,” says Homan. As bananas ripen, much of the resistant starch changes to sugar. But the health benefits of antioxidants and fiber outweigh the naturally occurring sugar. For those worried about blood sugar levels, pair bananas with a protein source such as peanut butter or a cheese stick for better control.

A small word of warning about unripe bananas: “If you’re not used to eating resistant starch, start slowly to let your body get used to it. Some people can experience constipation, gas and bloating at first,” adds Homan.

Another plus of this fruit? In addition to all the health benefits of bananas, they’re less expensive than many other fruits.

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.

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.”
