“When you create a meal centered around vegetables, you’re taking steps to improve and maximize your health,” says Liz Moore, registered dietitian at Beth Israel Deaconess Medical Center. Try these three meals today. — #HarvardHealth #Diet #Nutrition

Meatless Mondays, meet summer’s bounty: a wide variety of colorful, fresh summer vegetables now available in grocery stores, backyard gardens, and farmer’s markets. We’re talking sunshiny golden corn on the cob, deep purple eggplant, red beets, peppers of all hues, not to mention tomatoes, zucchini, green beans, cucumbers, and more. With a bit of simple prep, they’re ready to take center stage on your plate, reinforcing the joy of summer.

“Vegetables in our diet provide many benefits. And when you create a meal centered around them, you’re taking steps to improve and maximize your health,” says Liz Moore, the author of a heart-healthy cookbook and a registered dietitian at Harvard-affiliated Beth Israel Deaconess Medical Center.

Centering healthy vegetables on your plate

Making vegetables the stars of a meal is part of the “veg-centric” movement, which teaches people how to elevate even average vegetables to creative entrées and side dishes. The trend gives vegetables bold flavors by grilling, layering, caramelizing, or roasting them — steps you can take with a backyard grill or stovetop skillet.

Summer veggie meals have lots of important health perks. “Vegetables such as eggplant and beets of all colors are rich in fiber, Moore says. “Eating a high-fiber diet helps lower cholesterol and is linked to heart health, digestive health, and helping to maintain stable blood sugar levels. For those trying to lose weight, vegetables are low in calories and provide volume, which helps keep you full.”

Summer vegetables also have a wide variety of essential vitamins, minerals, and phytochemicals (beneficial plant chemicals) like flavonoids. “For example, carotenoids in cooked tomatoes are rich in lycopene, which is associated with inhibiting cancer growth and boosting the immune system. And beets are a good source of folate and potassium,” Moore says.

Three easy summer vegetable meals

Wondering what to do with the colorful harvest available to you? Moore suggests keeping it simple by making a meal of vegetables paired with whole grains or legumes (beans or lentils). Here are three meals that fill the bill.

Grilled eggplant steak with cucumber, tomato, onion, chickpea, and feta salad

  1. Slice an eggplant (from root to stem) into three-inch thick “steaks.” On each side, drizzle olive oil and a little black pepper. Grill on both sides until tender.
  2. Dice two tomatoes, one cucumber, and half a red onion. Add a can of rinsed, drained chickpeas. Toss with a dressing of olive oil, a little red wine vinegar, and oregano to taste.
  3. Serve the salad over the eggplant steak. Top with some diced feta cheese, if you like.

Veggie pita pocket with gazpacho

  1. Put a couple of tomatoes, a cucumber, a green pepper, half a red onion, some bread crusts, and a little olive oil into a blender. Blend until chunky or finer, as you prefer. Add salt, pepper, and cumin to taste, blending for a few more seconds. Chill for 30 minutes.
  2. Open a whole-wheat pita and spread a tablespoon of hummus inside. Add slices of zucchini and carrots, and some arugula, salad greens, or other vegetables that appeal to you.
  3. Serve the pita with half a cup of the gazpacho.

Quinoa-stuffed red peppers

Based on a recipe from BIDMC’s CardioVascular Institute’s Hungry Heart Cookbook by Liz Moore, RD, LDN

  1. Cut peppers in half, remove seeds, and lay them open side up on a dish.
  2. Mix cooked quinoa, diced tomatoes, and corn off the cob (you can grill the corn first and cut off the kernels for a special summer flair). Add low-fat grated cheddar cheese, canned (rinsed) black beans, one egg, and some spices to taste, such as a bit of cumin, chili powder, salt, and pepper.
  3. Use the mixture to stuff the peppers evenly, and then cook them on the grill in a grilling basket for about 30 minutes. You can also cook them in the oven at 350° F on a cookie sheet or in a roasting pan, checking at 30 minutes to see if they are done.

Other ideas include

  • grilled veggie kebabs with chunks of eggplant, zucchini, cherry tomatoes, and mushrooms. Serve on a bed of lettuce and add a little goat cheese.
  • whole-wheat pasta with a mix of sautéed vegetables that appeal to you.
  • salad with green leaf lettuce, raw green beans, cherry tomatoes, Kalamata or black olives, and half a hard-boiled egg. Top with a dressing you enjoy.

Which combinations of summer vegetables you choose can depend on cost, taste preferences, and how much time you want to spend cooking. If you’re in a hurry, go with a salad. If you have more time, try grilling or sautéing vegetables.

Finally, be open to inspiration from the bounty you see at the market. “Focus on getting a variety of colors in the vegetables you choose. The more colors there are on the plate, the more nutrients you’ll be consuming,” Moore says. “And try something new. Explore vegetables you’ve never tried before or new methods of cooking. Think of it as one of summer’s glorious adventures.”

The “little trees” are full of fiber, folate, vitamins and more. @ClevelandClinic #broccoli

“Eat your broccoli,” may be a familiar refrain from your childhood. Maybe you didn’t love broccoli as a kid, but your parents were onto something. The “little trees” are full of fiber, folate, vitamins and more.

Broccoli is a member of the Brassica genus of plants, also known as the cabbage family. Broccoli’s relatives include Brussels sprouts, cabbage, cauliflower, chard and watercress. Many Brassicas have strong flavors and mix well with meats and other vegetables.

“A pile of steamed broccoli doesn’t appeal to everyone,” recognizes registered dietitian Beth Czerwony, RD, LD. “But broccoli is incredibly versatile and can be used in so many different dishes. Toss it in with your stir fry, chop it fresh in a salad or roast it with your baby potatoes. And with an abundance of nutrients, there are many benefits of eating broccoli.”

Broccoli benefits

It’s worth finding ways to add broccoli to your diet because it’s a health-boosting dynamo. Here’s some motivation for you to get your green on: Some of the beneficial substances in broccoli are somewhat unique to the Brassica family of vegetables. Broccoli provides nutrients that may:

  • Reduce your risk of cancer.
  • Help control blood sugar.
  • Protect your gut.
  • Boost immunity.

As a superfood status, broccoli can improve your health with these five components:

1. Compounds to reduce cancer risk

“Broccoli offers some powerful molecules that protect your cells from damage,” says Czerwony. “Some of them even destroy cancer cells.”

Cancer-fighting molecules in broccoli include DIM, indole-3-carbinol and sulforaphane. According to studies, they may help:

  • Detoxify certain substances that promote the growth of cancer cells, which means they don’t remove the substances, but they remove the harmful effects.
  • Provide antioxidants, which prevent cell damage that can lead to cancer.
  • Stop the growth and spread of cancer cells.
  • Support apoptosis, your body’s process for destroying cells that could turn into cancer.

These anticancer molecules are in several of broccoli’s cruciferous veggie relatives, too. These nutrients don’t survive cooking or freezing. So, to get the benefits, raw broccoli is best.

“Some of these compounds are even more concentrated in broccoli sprouts,” notes Czerwony. “You can find broccoli sprouts in health food stores and many grocery stores. Sprouts are also easy to grow at home using a sprouting kit.”

2. Nutrients to help manage blood sugar

Both human and lab studies suggest compounds in broccoli may help lower blood sugar in people with Type 2 diabetes. This effect may be due to the antioxidants in broccoli, like vitamin C.

Research shows that fiber can also help with blood sugar management. At 2.5 grams of fiber per cup, broccoli is a good source of this nutrient.

3. Ligands to protect your gut

In a nonhuman study, researchers found that broccoli can help protect the lining of your small intestine. Compounds found in broccoli, called aryl hydrocarbon receptor ligands, help keep small intestine cells working well.

Why do those cells matter so much? When your small intestine lining is healthy, it only allows water and nutrients to pass through it into your bloodstream.

But when the cells of the lining are damaged, undigested food particles, bacteria and other disease-causing particles may pass through. A damaged small intestine lining can lead to infections and inflammation. It can also prevent you from absorbing the nutrients you need.

4. Vitamin C to boost immunity

Vitamin C is well-studied as an immune-boosting nutrient. When you don’t have enough vitamin C, you’re more likely to get infections.

The antioxidant effects of vitamin C also help your body keep free radicals under control. “Free radical damage is linked to all kinds of problems, including Alzheimer’s disease, autoimmune diseases, cancer, heart disease and Parkinson’s disease,” says Czerwony. When you don’t have enough antioxidants to neutralize free radicals, they damage your cells.

Surprising but true: Broccoli has more vitamin C than oranges. In 1 cup of the green cruciferous veggie, you get a whopping 81 milligrams of vitamin C. That’s 90% of the daily U.S. recommended dietary allowance (RDA) for adults. (An orange has about 70 milligrams.)

5. Nutrients to help heart health

Research suggests certain bioactive compounds in broccoli may boost your heart health in a variety of ways. It may:

  • Lower triglycerides and LDL (“bad”) cholesterol: “High LDL can lead to fatty deposits on your artery walls, increasing your risk of artery disease, stroke and heart attack,” Czerwony explains. Research shows that eating broccoli can lower triglycerides, a type of fat, as well as LDL.
  • Provide fiber: According to a review of 22 clinical trials, fiber can reduce your risk of cardiovascular and coronary artery disease.
  • Reduce calcium buildup in blood vessels: When calcium builds up on your blood vessel walls, it increases your risk of heart attack and stroke. According to research, broccoli can help reduce this calcium buildup.

Is frozen broccoli healthy?

“If you want those anticancer compounds like sulforaphane, choose fresh broccoli,” advises Czerwony. Freezing inactivates sulforaphane.

“Frozen broccoli also loses a bit of its vitamin content. But overall, frozen broccoli is still very healthy. It’s better than not eating any broccoli because you still get a lot of the health benefits,” she continues.

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.

(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.”
