All the Reasons You Should Eat Strawberries. These berries benefit your memory, boost your immune system and keep your heart healthy @ClevelandClinic #healthaware

Strawberries are an iconic summer fruit — delicious in lemonade, on shortcakes or just straight out of the basket. And it turns out they may be the sweetest way to stay healthy, too. Registered dietitian Bailey Flora, MS, RDN, LD, explains the benefits of strawberries and what nutrients they contain that make strawberries so good for you.

Why are strawberries good for you?

“Strawberries give you a lot of nutritional value for very few calories,” says Flora. “They’re tasty but naturally low in sugar. That’s a combination that’s hard to beat.”

For starters, strawberries are loaded with vitamin C. Eight medium strawberries contain 160% of your daily recommended amount — the amount that the U.S. Food and Drug Administration (FDA) recommends you eat every day. That’s more vitamin C than you get from an orange, the fruit famous for its vitamin C.

Strawberries are also packed with antioxidants, which protect cells from damage. The primary antioxidant in strawberries is anthocyanin, which gives the fruit its color. The amount of anthocyanin in strawberries increases as the fruit ripens. So, the redder the berry, the more antioxidants it contains.

Strawberries also have fiber and several other important vitamins and minerals, including manganese, potassium and folic acid. And strawberries have less natural sugar than other popular fruits such as apples and bananas.

Health benefits of strawberries

Strawberries are a nutrient-rich snack that can:

1. Boosts brain power

As your brain ages, it can lose some of its mental sharpness. But according to research, eating strawberries protects your brain’s processing powers as you get older.

The Nurses’ Health Study measured brain function in more than 16,000 participants over six years. It found that people who ate the most blueberries and strawberries had less cognitive decline — their thinking and processing abilities didn’t weaken as much. They had the brain power of someone up to two and a half years younger.

In more good news for strawberry lovers: The results of the Rush Memory and Aging Project showed that people who ate strawberries were 34% less likely to develop Alzheimer’s disease.

Researchers believe the protective effects are due to the antioxidants that safeguard cells. Some of the antioxidants in strawberries also reduce systemic inflammation, when your body is in a state of constant inflammation (swelling and irritation). Systemic inflammation is a key factor in the development of Alzheimer’s disease.

2. Strengthens your immune system

Strawberries are a great source of vitamin C (ascorbic acid), which you need to get from food, as your body can’t produce it. In rare cases, people who don’t get enough of this crucial vitamin develop scurvy, a disease that causes bleeding, bruising and anemia.

Vitamin C plays an important role in wound healing. And it may prevent and treat respiratory and systemic infections too. Research shows that vitamin C increases the production of:

T-cells, which remove infected and cancerous cells.
B-cells, which create antibodies so your body can better defend against germs in the future.

Vitamin C is also anti-inflammatory, lowering your stress response triggered by illness or just your busy life. To ward off germs, researchers suggest getting 100 to 200 milligrams (mg) of vitamin C a day — and more when you’re sick. As eating eight medium strawberries gives you 160 mg, it takes just a handful of berries to help keep your immune system in good shape.

“There isn’t enough evidence to say whether vitamin C can prevent colds and the flu,” says Flora. “And it can be more beneficial to choose vitamin-C-rich foods like strawberries over vitamin C supplements, as you get additional health benefits. With strawberries, that includes fiber and other phytonutrients and vitamins that cannot be replicated in a vitamin supplement.”

3. Protects heart health

Flora says that popping a few strawberries in your mouth isn’t just a way to stave off hunger — it’s also a heart-healthy food choice. Research shows that strawberries can help prevent several conditions that can lead to heart disease and stroke, as well as diabetes, which increases the likelihood of heart disease. Eating more strawberries can help you:

Lower cholesterol

In one small study, participants consumed two drinks a day, each made with 25 milligrams of freeze-dried strawberry powder blended with water. That’s about the same as eating 3.5 cups of fresh strawberries a day. After a month, the participants’ total cholesterol was 5% lower.

The cholesterol-lowering results of that study were echoed in another study that gave participants the same amount of freeze-dried strawberry powder. But this time, they consumed the drink for two months. Researchers compared the results to a group that just drank more water. Those who sipped the strawberry drink saw their cholesterol decrease by 10%.

Decrease triglycerides

Triglycerides are fats found in your blood. Having high triglycerides increases your risk of heart disease. And when triglycerides break down, they leave byproducts that trigger inflammation, attracting sticky deposits to blood-vessel walls. That material can clog your arteries (atherosclerosis), explains Flora.

But eating a pound of strawberries a day may reduce triglycerides by 20%. That’s the result of one study, which also found that strawberries reduced total cholesterol by 8%.

4. Reduces inflammation

Widespread internal inflammation contributes to multiple diseases, including heart disease. Lifestyle factors like a poor diet, low physical activity and smoking can lead to inflammation.

Eating more strawberries is a step in the right direction to boost your heart health, says Flora. That’s because the most prevalent antioxidants in strawberries are anthocyanins, known for their anti-inflammatory effects.

5. Helps manage blood sugar

Too much glucose (sugar in your blood) is a risk factor for Type 2 diabetes, making you more likely to develop heart disease, too. If you’re watching your blood sugar levels, strawberries are a good way to satisfy your sweet tooth.

In a Finnish study, people who ate strawberries with a piece of white bread released 26% less insulin compared with eating bread with a cucumber. Participants also ate the bread with other berries, including raspberries and cranberries. Only strawberries weakened the post-meal blood sugar spike.

Strawberries are a great addition to a healthy diet, especially when you eat them on their own — Flora advises laying off the calorie-laden whipped cream, cake or ice cream. (Sorry!) They’re delicious, full of good-for-you nutrients and low in sugar. Try this strawberry smoothie. (Surprise — it’s green!)

How does breaking a sweat boost immunity?@ClevelandClinic

Cleveland Clinic

@ClevelandClinic

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.

Q: How does breaking a sweat boost immunity?

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.

Q: How much exercise do you need?

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.

Q: What types of exercise are most helpful?

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.

Q: Can too much exercise set your immune system back?

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.

Q: Can exercise make an illness worse?

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.

9 Ways Alcohol Affects Your Health @ClevelandClinic

February 15, 2024

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.
