Avocados are jam-packed with nutrients and vitamins and can make a delicious, nutritious addition to your diet.

Millenials may get flak for being the “avocado toast generation,” but honestly, they may be onto something! Avocados are as nutritious as they are delicious, and they’re jam-packed with vitamins and nutrients.

Avocados include vitamins C, E, K1, B6 and folate, plus essential minerals like potassium and copper. They’re low in sugar, loaded with fiber and high in monosaturated fats, aka “good” fats. Oh, and did we mention that they taste great and they’re super versatile?!

Registered dietitian Julia Zumpano, RD, LD, shares a few more good reasons to give these wrinkly green fruits a second look — plus, how to add them to your regular rotation.

Are avocados good for you?

“Avocados are a great addition to a healthy diet,” Zumpano confirms, “and there are hundreds of varieties to choose from, ranging from big to small and wrinkly to smooth.”

What they have in common: A big round pit, creamy green flesh and a whole lot of nutrients crammed into a handy, pear-shaped package.

Just don’t go overboard. Avocados are packed with nutrients, but they’re also packed with calories. A 50-gram portion — about a third of a medium-sized avocado — has about 75 calories. And an entire large avocado can add upward of 400 calories to your daily diet.

Like most things, Zumpano says, moderation is key. “As long as you’re paying attention to portion sizes, avocados are very healthy foods to include in your food repertoire.”

Benefits of avocados

Whether you’re adding a slice to a salad or sandwich or using them as an ingredient in a more complicated recipe, Zumpano says avocados have a lot going for them health-wise.

Here are some of the many nutrients and vitamins packed into just a single avocado:

High in ‘good’ fats

You might’ve heard that avocados are high in fat — and that’s true, but it doesn’t mean you should avoid them! A medium avocado has 22 grams of fat, which includes 15 grams of monounsaturated fats, aka “good” fats.

“Avocados are rich in heart-healthy monounsaturated fats, which help lower your LDL, or ‘bad’ cholesterol,” Zumpano says. “Low LDL levels reduce your risk of heart disease and stroke.”

The American Heart Association says most of the fats you eat should be monounsaturated or polyunsaturated, confirming that avocados fit the bill as part of a healthy diet.

You can even swap avocado in for less-healthy fats in your home cooking. Here are some additional ways you can add this smooth, creamy fruit to your diet.

Spread avocado on a sandwich in place of mayonnaise.
Instead of dunking veggies into dips made with cheese or sour cream, try guacamole.
Forego shredded cheese on your salad and add avocado slices instead.
In baking recipes, replace butter or oil with mashed avocado, like in these chocolatey avocado brownie bites.

“If you use avocado to replace other fats, you can enjoy the flavor and nutrients and also cut down on saturated fats,” Zumpano says.

Lots of vitamins

Let’s talk vitamins: In simple terms, avocados have a lot of them! Here are the vitamins that are most abundant in avocados and what they do for your health:

Vitamin K1, or phylloquinone, is important for blood clotting, which helps stop wounds from bleeding. It also plays a role in strengthening your bones. For most adults, the daily recommended amount of vitamin K ranges from 90 to120 micrograms. Half an avocado has about 21 mcg.
Vitamin C, aka ascorbic acid, helps keep your immune system healthy. It also plays a role in the health of your tissues, blood vessels, bones and more. Depending on your age and sex, you need anywhere from 75 to 120 milligrams of vitamin C per day; half an avocado has about 10 mg.
Vitamin E, or alpha-tocopherol, is a powerful antioxidant that prevents cell damage and helps maintain muscle function. Most adults only need 15 mg of vitamin C per day, and half an avocado will give you about 4 mg of it.
Vitamin B6, also known as pyridoxine, helps your body convert food into energy. You only need a small amount of vitamin B6 each day (just 1.2 to 2 mg, depending on your age and sex), but half an avocado has about .25 mg, putting you well on your way to that daily goal.
Folateis a B vitamin that’s important for normal cell function and tissue growth. It helps your body form red blood cells and DNA, which is especially critical when you’re pregnant (but still important if you’re not). Half an avocado has about 20% of your daily recommended amount.

Low in sugar

Though most fruits are high in natural sugars, avocados rank very low on the sweetness scale. “A whole avocado has under 1.5 grams of sugar, while one medium apple, by comparison, has about 19 grams,” Zumpano points out. (Psst: It’s important to note that not all sugars are created equal! Fruit is still super-healthy.)

High in fiber

Avocados are a good source of fiber, which is a type of carbohydrate that your body can’t break down. You need both soluble and insoluble fiber — and lucky for you, avocados have both.

“Fiber can lower cholesterol and blood sugar, keep you regular and help you feel full and satisfied after a meal,” Zumpano states. Most adults need 25 to 35 grams of fiber per day, depending on your age and sex. Half an avocado provides about 7 grams.

Packed with potassium

Surprise! “Avocados actually contain more potassium than bananas,” Zumpano reveals. Half a large avocado provides about 485 mg of potassium, while a whole banana provides about 420 mg. (Most adults need 2,600 to 3,400 mg per day.)

This essential mineral is beneficial for blood pressure control and heart health. Low blood potassium can increase your blood pressure, raise your risk of kidney stones and even pull calcium out of your bones.

Increases your copper intake

Think past pennies: Copper is actually an essential trace mineral that your body needs in order to function correctly. Most Americans don’t get enough of it in their diets, but half an avocado will get you 20% of your daily recommended amount.

“Copper helps your body metabolize iron, and it plays a role in a healthy immune system and nervous system,” Zumpano explains.

Tips for enjoying avocados

“A perfectly ripe avocado is slightly firm but not rock-hard,” Zumpano says. “If it’s not ripe but you can’t wait to eat it, store it in a paper bag on the counter until it gives a little when you squeeze it.”

A ripe-but-not-too-ripe avocado is a time-limited treasure, so dive right in and get creative with your avocado creations, or embrace the millennial method and enjoy some avocado toast.

But if you need to store it for a couple of days, just be sure to keep it in the fridge — not submerged in water, as some TikTokkers recommend. Some people call it a “food hack,” but it can easily lead to foodborne illness.

“You can even freeze avocado slices if you’re worried you won’t use them in time,” Zumpano suggests. “Then, you can easily throw them into a smoothie.”

Many older adults focus on exercise and diet to stay healthy. But one of the worst offenders to health—poor balance—is often an afterthought. “I see a lot of older adults who are nonchalant about balance,” says Liz Moritz, a physical therapist at Harvard-affiliated Brigham and Women’s Hospital.

Unfortunately, imbalance is a common cause of falls, which send millions of people in the United States to emergency departments each year with broken hips and head injuries. But there are many things you can do to improve your balance. The strategies below are some of the most effective.

Physical therapy

Physical therapy for balance focuses on the ability of the joints and brain to communicate, the balance system in the ear (the vestibular system), and vision. “We coordinate all three with exercises such as standing on one foot, first with the eyes open, and then with the eyes closed. We also work on joint flexibility, walking, and lower-extremity exercises on one or two legs,” says Moritz. Other exercises that boost balance include chair stands (see “Move of the month”) and squats. Make sure you get training before attempting these exercises at home.

Muscle strengthening

“Core strength is very important for balance. If the abdominal muscles in your core are weak, they cannot support your limbs, especially when you’re walking. If the gluteal muscles in your buttocks and hips aren’t strong, they won’t be able to propel you forward,” says Moritz. Muscle strengthening can help. Moritz suggests starting with gentle core exercises like a pelvic tilt (lie on the floor with your knees bent up, then roll your pelvis up) and then moving to more intense exercises such as wall planks (stand six inches from a wall, keeping your body rigid, then lean forward with your forearms flat against the wall, and hold the position for 20 seconds). Leg lifts will strengthen the gluteal muscles, and adding resistance bands to leg lifts makes the exercise even more effective.

Tai chi and yoga

“Tai chi and yoga are exercises that make you pay attention to the control and quality of movement, rather than the quantity, which improves your balance,” says Moritz. In tai chi, you practice slow, flowing motions and shift your weight from one limb to another. Yoga incorporates a series of focused postures and breathing. Both exercises increase flexibility, range of motion, leg and core strength, and reflexes. The result: you become better at balancing in a number of different positions, which helps you avoid falling if you encounter uneven pavement or obstacles in your path.

Vision correction

“If you can’t see where you’re going, your fall risk goes up,” says Moritz. “A lot of people I treat for balance are here be-cause they tripped when they didn’t see something on the floor.” The fix may be as simple as a new eyeglasses prescription. Get a comprehensive, dilated eye exam every one or two years if you’re 65 or older, every one to three years if you’re age 55 to 64, and every two to four years if you’re 40 to 54. If you have an increased risk for other eye conditions, you may need an eye exam more often.

Assistive walking devices

A cane or a walker can complement your balance and give you more stability and confidence walking. But don’t buy a device on your own. “If it’s too high or too low, that can cause a fall. You need to get it measured, and you need training to learn how to use it,” says Moritz. Training takes just a few physical therapy sessions. Walkers are available with wheels intended for different terrain, lockable brakes, seats, baskets, and other features such as headlights. Canes are available with various handgrips and bases.

5 surprising benefits of walking: @HarvardHealth #healthaware #physicalactivity

5 surprising benefits of #walking: Any physical activity is a boon to your overall health. But walking in particular comes with a host of benefits. https://bit.ly/3uyNvhI #HarvardHealth

The next time you have a check-up, don’t be surprised if your doctor hands you a prescription to walk. Yes, this simple activity that you’ve been doing since you were about a year old is now being touted as “the closest thing we have to a wonder drug,” in the words of Dr. Thomas Frieden, former director of the Centers for Disease Control and Prevention.

Of course, you probably know that any physical activity, including walking, is a boon to your overall health. But walking in particular comes with a host of benefits. Here’s a list of five that may surprise you.

1. It counteracts the effects of weight-promoting genes. Harvard researchers looked at 32 obesity-promoting genes in over 12,000 people to determine how much these genes actually contribute to body weight. They then discovered that, among the study participants who walked briskly for about an hour a day, the effects of those genes were cut in half.

2. It helps tame a sweet tooth. A pair of studies from the University of Exeter found that a 15-minute walk can curb cravings for chocolate and even reduce the amount of chocolate you eat in stressful situations. And the latest research confirms that walking can reduce cravings and intake of a variety of sugary snacks.

3. It reduces the risk of developing breast cancer. Researchers already know that any kind of physical activity blunts the risk of breast cancer. But an American Cancer Society study that zeroed in on walking found that women who walked seven or more hours a week had a 14% lower risk of breast cancer than those who walked three hours or fewer per week. And walking provided this protection even for the women with breast cancer risk factors, such as being overweight or using supplemental hormones.

4. It eases joint pain. Several studies have found that walking reduces arthritis-related pain, and that walking five to six miles a week can even prevent arthritis from forming in the first place. Walking protects the joints — especially the knees and hips, which are most susceptible to osteoarthritis — by lubricating them and strengthening the muscles that support them.

5. It boosts immune function. Walking can help protect you during cold and flu season. A study of over 1,000 men and women found that those who walked at least 20 minutes a day, at least 5 days a week, had 43% fewer sick days than those who exercised once a week or less. And if they did get sick, it was for a shorter duration, and their symptoms were milder.

9 Ways Alcohol Affects Your Health @ClevelandClinic

What Does Alcohol Do to Your Body? 9 Ways Alcohol Affects Your Health

Alcohol affects your whole body, from your liver and immune system to your brain and mental health

You probably already know that excessive drinking can affect you in more ways than one.

There are the empty calories that can lead to weight gain. There’s the potential for injury and regrettable choices. And don’t forget about the hangovers of course.

Heavy drinking can also lead to a host of health concerns, like brain damage, heart disease, cirrhosis of the liver and even certain kinds of cancer.

And that’s on top of the toll that alcohol use can take on relationships, not to mention the potential for financial strain and legal troubles.

But even moderate alcohol use changes the way your body functions.

We talked with hepatologist Shreya Sengupta, MD, about how alcohol use affects your body and your emotional health.

“Some people think of the effects of alcohol as only something to be worried about if you’re living with alcohol use disorder, which was formerly called alcoholism,” Dr. Sengupta says.

“But when you consider how alcohol is metabolized and used by your body, we can start to see that even moderate and social drinking affects our health to some degree.”

Dr. Sengupta shares some of the not-so-obvious effects that alcohol has on your body.

Liver

Your liver detoxifies and removes alcohol from your blood through a process known as oxidation. When your liver finishes that process, alcohol gets turned into water and carbon dioxide.

But when you ingest too much alcohol for your liver to process in a timely manner, a buildup of toxic substances begins to take a toll on your liver.

If alcohol continues to accumulate in your system, it can destroy cells and, eventually, damage your organs.

“When your liver is overwhelmed by oxidizing alcohol, it generates molecules that inhibit fat oxidation,” Dr. Sengupta explains. “The fats build up. Over time, it can lead to a condition known as steatotic liver disease.”

Steatotic liver disease used to go by the name fatty liver disease.

Steatotic liver disease develops in about 90% of people who drink more than 1.5 to 2 ounces of alcohol per day. That’s about one shot glass worth.

With continued alcohol use, steatotic liver disease can lead to liver fibrosis. Eventually, you can develop permanent and irreversible scarring in your liver, which is called cirrhosis.

“The good news is that earlier stages of steatotic liver disease are usually completely reversible in about four to six weeks if you abstain from drinking alcohol,” Dr. Sengupta assures.

Cirrhosis, on the other hand, is irreversible and can lead to liver failure and liver cancer, even if you abstain from alcohol.

Metabolism

You probably are keenly aware of the so-called “beer belly.” That’s shorthand for a round midsection that some people associate with drinking too much beer.

In reality, there’s no evidence that drinking beer (or your alcoholic beverages of choice) actually contributes to belly fat.

But there’s plenty of research to back up the notion that alcohol does lead to weight gain in general. Even for people who aren’t particularly heavy drinkers.

“Drinking gives your body work to do that keeps it from going about its other processes,” Dr. Sengupta notes. “Alcohol distracts your system from its regularly scheduled duties, including things like metabolizing carbohydrates and fats.”

Once you take a drink, your body makes metabolizing alcohol a priority — above processing anything else.

That’s because your body already has processes in place that allow it to store excess proteins, carbohydrates and fats. But there isn’t a storage tank for alcohol. So, your system prioritizes getting rid of alcohol before it can turn its attention to its other work.

That allows excess calories from the foods you eat to sit around, leading to weight gain.

Gut health

Your gut microbiome is a hotbed of bacteria that help keep your digestive system happy and healthy. The trillions of microbes in your colon and large and small intestines are critical to proper digestion. They also help fend off inflammation and support healthy metabolism.

When you drink too much alcohol, it can throw off the balance of good and bad bacteria in your gut.

“Alcohol can kill the good bacteria that live in your gut, allowing bad bacteria to grow unchecked,” Dr. Sengupta explains. “That can lead to problems with digestion, inflammation and even organ damage.”

Having a glass of wine with dinner or a beer at a party here and there isn’t going to destroy your gut. But even low amounts of daily drinking and prolonged and heavy use of alcohol can lead to significant problems for your digestive system.

Heart health

Too much alcohol is bad for your heart. Alcohol can cause:

Increased heart rate.
Spikes in blood pressure.
Irregular heartbeats (arrhythmia).
A weakening in your heart (cardiomyopathy).

Warnings from the World Heart Federation go so far as to state that no amount of alcohol is safe for your ticker.

But wait, you may be thinking, what about those headlines that claim red wine is supposed to be good for my heart?

There are a few studies that associate red wine with improved heart health in lab tests. But no research proves that red wine causes any improvements in heart health in people.

“The reality is that alcohol causes more health troubles than it could ever help,” Dr. Sengupta reinforces. “And that goes for your heart, as well as the rest of your body.”

Pancreas

Your pancreas helps your body digest food and manage your blood sugar. Drinking alcohol changes how your pancreas works.

“Your pancreas secretes fluids. Alcohol use can thicken those fluids, which can clog the ducts that those fluids flow out of,” Dr. Sengupta explains.

Like a clog in a drain, those thickened fluids can jam up your ducts. That can lead to pancreatitis, which is inflammation of the pancreas.

Pancreatitis can be a short-term (acute) condition that clears up in a few days. But prolonged alcohol abuse can lead to chronic (long-term) pancreatitis, which can be severe.

Cancer risk

The U.S. Centers for Disease Control and Prevention (CDC) has a clear warning regarding the connection between drinking and cancer: “The less alcohol you drink, the lower your risk for cancer.”

Why?

Your body breaks alcohol down into a chemical called acetaldehyde, which damages your DNA. Damaged DNA can cause a cell to grow out of control, which results in cancerous tumors.

Alcohol use has been shown to raise your risk for several kinds of cancer. That includes cancers of the:

Mouth.
Esophagus.
Throat.
Liver.
Breast.
Colon and rectum.

Immune system

If you drink every day, or almost every day, you might notice that you catch colds, flu or other illnesses more frequently than people who don’t drink. That’s because alcohol can weaken your immune system and make your body more susceptible to infection.

“We see lower levels of a specific kind of white blood cells called lymphocytes in people who drink heavily for long periods of time,” Dr. Sengupta reports. “That can leave them more vulnerable to infectious diseases.”

Brain

The morning after a night of over-imbibing can cause some temporary effects on your brain. Things like trouble concentration, slow reflexes and sensitivity to bright lights and loud sounds are standard signs of a hangover, and evidence of alcohol’s effects on your brain.

Long-term alcohol use can change your brain’s wiring in much more significant ways. Ways that your standard hangover cures won’t even begin to touch.

“Excessive alcohol consumption can cause nerve damage and irreversible forms of dementia,” Dr. Sengupta warns.

Mental health

Alcohol is a depressant. And prolonged alcohol use can lead to mental health conditions like anxiety and depression. Chronic misuse can also lead to paranoia and hallucinations.

Even drinking a little too much (binge drinking) on occasion can set off a chain reaction that affects your well-being. Lowered inhibitions can lead to poor choices with lasting repercussions — like the end of a relationship, an accident or legal woes. Each of those consequences can cause turmoil that can negatively affect your long-term emotional health.

“Alcohol tends to cause more problems than it solves for a lot of people,” Dr. Sengupta emphasizes. “If drinking is affecting your health, your relationships, your work, your finances, it’s time to make some serious changes.”

Ready to stop drinking and improve your health? These tips may help.

If you need more guidance to quit drinking, the Substance Abuse and Mental Health Services Administration (SAMHSA) offers a hotline, 24/7, 365 days a year. Call 1.800.662.HELP (4357).

Alcoholics Anonymous is available almost everywhere and provides a place to openly and nonjudgmentally discuss alcohol issues with others who have alcohol use disorder.
