Science: Cocoa Protects Your Heart

Most of us spend long hours each day sitting—at our desks, in our cars, or on the couch at the end of the day. It's no secret that this is one of the most dangerous habits of the modern era, with potential harm to a range of vital body systems.

Prolonged sitting damages blood circulation, increases the risk of heart disease, obesity, and depression. Surprisingly, studies show that even physical fitness doesn't always compensate for this damage. 

 

Now for the good news: researchers from the University of Birmingham have found that a hot drink containing natural cocoa may prevent the damage to blood vessels caused by hours of continuous sitting. In other words, one cup of cocoa might protect your body more effectively than even physical exercise.

Strong Protection Even for People Who Don't Exercise 

 

The study, published in The Journal of Physiology, examined 40 young, healthy men between the ages of 18 and 34—some of whom exercised regularly and others who didn't at all. Each participant came to the laboratory for two sessions: in the first, they drank cocoa rich in flavanols, plant compounds with antioxidant properties found in natural cocoa powder, and in the second session, they drank regular cocoa containing little of this active ingredient.

The participants were then asked to sit without moving for two hours while researchers measured their blood vessel function using ultrasound. The findings showed unequivocally that while drinking regular cocoa led to a significant decline in blood vessel function in the arms and legs, drinking natural, flavanol-rich cocoa completely prevented this decline. Blood flow remained normal, even after two hours of sitting.

Additionally, it's interesting to note that the participants' fitness level didn't change the outcome. Even men who exercised regularly experienced reduced blood flow when they drank regular cocoa and full protection when they drank the flavanol-rich beverage, just like the other subjects. 

 

The Unique Compound That Protects the Heart 

 

The researchers explain that the flavanols in cocoa promote the production of a molecule called nitric oxide, which is responsible for dilating blood vessels and maintaining their flexibility. When we sit for long hours, blood flow slows down and nitric oxide levels drop, making it harder for blood vessels to expand and eventually damaging heart health.

Dr. Catarina Rendeiro, a nutrition scientist from the University of Birmingham who led the study, wrote in the article that "our body may be at rest when we're sitting, but our blood vessels are under constant stress. Therefore, finding simple ways to reduce this damage can help prevent cardiovascular disease." 

 

This study joins a series of findings from recent years demonstrating the benefits of natural flavanols—the same components found not only in cocoa but also in green tea, apples, grapes, and even red wine. These are compounds that improve blood vessel function, reduce blood pressure, and contribute to heart health. 

 

However, it's important to remember that this isn't justification for drinking sugar-laden chocolate milk or commercial cocoa with artificial ingredients. The researchers emphasize that the significant effect was measured only in natural cocoa drinks containing a high concentration of flavanols. To enjoy these benefits, look for a drink with at least 70% cocoa, or natural powder without sugar.

How Dangerous Is Prolonged Sitting, Really? 

 

According to data collected over the past decade, the average person spends more than six hours a day sitting. Studies have shown that after just two hours of inactivity, blood vessels in the legs begin to lose their flexibility. The even more concerning finding is that even people who exercise regularly suffer from this effect—meaning one evening workout doesn't necessarily cancel out the damage from an entire day spent sitting.

Researchers estimate that consuming flavanols before prolonged sitting can reduce these negative effects, especially when combined with simple habits like getting up every half hour, stretching your legs, or taking walking breaks. And of course, maintaining physical fitness at least at a basic level is still the most important tool for improving health across all metrics.

Practical Tips for Implementing These Findings  

 

While the research is promising, experts recommend a multifaceted approach to combat the dangers of prolonged sitting: 

 

Choose Your Cocoa Wisely 

 

Not all cocoa products are created equal. To get the protective benefits shown in the study: 

 

 Opt for high-quality dark chocolate with at least 70% cocoa content 

 

Use unsweetened natural cocoa powder when making hot drinks 

 

 Avoid commercial hot chocolate mixes that are loaded with sugar and contain minimal actual cocoa 

 

Check labels for flavanol content when available—some specialty brands now list this information

Combine Cocoa with Movement 

 

The researchers stress that cocoa isn't a magic bullet that allows you to sit indefinitely without consequences. 

 

The best approach combines flavanol-rich foods with regular movement: 

 

Set hourly reminders to stand up and move around 

 

Take short walking breaks every 30-60 minutes 

 

Perform simple stretches at your desk  

 

Consider a standing desk or alternating between sitting and standing throughout the day 

 

Walk during phone calls when possible

Other Flavanol-Rich Foods to Include 

 

Beyond cocoa, you can boost your flavanol intake through various foods: 

 

Green tea - contains catechins, a type of flavanol 

 

Berries - especially blueberries and strawberries 

 

Apples - particularly with the skin on 

 

Red grapes - the source of flavanols in red wine 

 

Nuts - especially almonds and hazelnuts

The Bigger Picture: Sedentary Lifestyle Risks  

 

This research highlights a broader public health concern. The World Health Organization has identified physical inactivity as the fourth leading risk factor for global mortality. Beyond cardiovascular issues, prolonged sitting is associated with: 

 

Metabolic syndrome - including increased blood sugar and cholesterol levels 

 

Musculoskeletal problems - particularly back and neck pain 

 

Mental health issues - including increased risk of anxiety and depression 

 

Reduced life expectancy - even among those who exercise regularly

A Simple Addition to Your Daily Routine 

 

What makes this research particularly exciting is its simplicity. Unlike many health interventions that require significant lifestyle changes, adding a cup of high-quality cocoa to your morning routine is relatively easy and enjoyable. 

 

The study's lead researcher emphasizes that this is especially relevant for office workers, students, drivers, and anyone else whose occupation requires long periods of sitting. A morning cup of flavanol-rich cocoa could provide protection throughout the workday, though the researchers are still investigating exactly how long the protective effects last.

Looking Forward while we wait for more research, there's little downside to incorporating natural, high-quality cocoa into your daily routine—especially if you spend significant time sitting. Just remember to choose products with high cocoa content and minimal added sugar, and don't let a cup of cocoa replace the fundamental need for regular movement throughout your day.

10 Easy Ways to Slash Sugar from Your Diet

Cut the sweetness
You may not be eating Oreos by the roll or guzzling cans of Coke, but that doesn't mean sugar's absent from your diet. You're likely eating sugar throughout the day without even realizing it, says Amari Thomsen, RD, owner of Chicago-based nutrition consulting practice . Sugar is added to foods that don't even taste all that sweet, like breads, condiments, and sauces. And it adds up: although the American Heart Association recommends women consume no more than six teaspoons of added sugar per day (or about 100 calories), most of us take in double that. (One note: we're talking about added sugar, not the naturally occurring sugars found in dairy and fruit.) A high-sugar diet boosts your odds of , , and , not to mention . Slash your sugar intake now with these 10 expert tips.

Read from labels
You'll quickly realize just how often sugar is added to foods when you look for it on ingredients lists. "Even things that you don't think are sweet, like tomato sauce, crackers, condiments, and salad dressings can be packed with sugar," says Diane Sanfilippo, certified nutrition consultant and author of The 21 Day Sugar Detox. Ingredients are listed in order of how much exists in the product, so if sugar's near the top, that's a red flag.
Learn sugar substitutes
When you read food labels, you'll need to look for more than just the word "sugar." Sugar hides under several sneaky names, including high fructose corn syrup, dried cane syrup, invert sugar, molasses, sucrose (or any word ending in "-ose"), brown rice syrup, honey, and maple syrup. These can be listed separately on ingredients lists, so many foods, even seemingly healthy ones like yogurt and cereal, may contain three or four different . If several sugars appear on the label, it's an indication that the food is less healthy than you may think.
Buy unsweetened
Once you know where sugar hides, you can start making changes. One strategy: buy foods labeled "no added sugar" or "unsweetened." You'll find unsweetened versions of these common foods in most grocery stories: non-dairy milk like almond and soy, nut butters (look for those made with only nuts and salt), applesauce, oatmeal, and canned fruit (they should be packed in juice—not syrup).
Don't go cold turkey
Going cold turkey on sugar isn't realistic for most people. Thomsen suggests cutting back slowly. If you normally put two packets of sugar in your , for instance, try one for a week, then half, and finally add only a splash of milk. For your yogurt, mix half a serving of sweetened yogurt with half a serving of plain, and eventually move on to adding natural sweetness with fresh fruit.
Think protein and fats
Unhealthy carbs loaded with sugar can cause blood sugar to rise rapidly (and dive just as quickly, leaving you hungry again). To minimize this rapid rise and fall, pair protein, healthy fats, and fiber with your meal, all of which can slow down the release of blood sugar in your body and keep you full for longer. (At breakfast, that means adding almonds to your usual oatmeal or pairing eggs with your morning toast, and for your , a slice of turkey breast or cheese along with your apple, suggests Thomsen.) Fats are a key player because they help keep you fuller for longer, thus helping to decrease your desire for sugar, adds Sanfilippo. Focus on fats like avocados, nuts, seeds, and like olive oil, walnut oil, and coconut oil.

We’ve heard it a million times—the added sugars in soda can pack on the pounds or prevent you from losing weight. But soda is a hard habit to kick. Watch the video to get on the path toward a soda-free life.

Add more flavour
Sanfilippo loves using vanilla bean and vanilla extract, spices, and citrus zests to add sweetness to foods without having to use sugar—and for zero calories. Order an unsweetened latte and add flavor with cocoa or vanilla powder. Skip the flavored oatmeal and add a sweet kick with cinnamon, nutmeg, and ginger. One bonus for sprinkling on the cinnamon: according to a meta-analysis in the , the spice has been shown to naturally regulate blood sugar, which helps control your appetite.

Don't drink it
Avoiding soda is a good idea, but that's not the only sugar-packed drink out there. Even drinks that are considered healthy can contain more of the sweet stuff than you're supposed to have in an entire day. Case in point: "enhanced" waters (eight teaspoons per bottle), bottled iced teas (more than nine teaspoons per bottle), energy drinks (almost seven teaspoons per can), bottled coffee drinks (eight teaspoons per bottle), and store-bought smoothies (more than a dozen teaspoons—for a small).

Enjoy dessert
You can still indulge in an occasional sweet treat after you resolve to slash sugar. The idea is to avoid wasting your daily sugar quota on non-dessert foods like cereals, ketchup, and bread. To avoid overdoing it, set specific rules about when you may enjoy dessert: only after dinner on the weekends or at restaurants as a special treat, Thomsen suggests.

Stick with it
At first, cutting down on sugar can feel like an impossible task. Eventually, though, your taste buds will adjust. Super-sweet foods like ice cream and candy will start to taste too sweet. When you could have a whole slice of cake before, now a couple bites will be enough. You'll notice the and vegetables—and yep, they'll taste better, too.

Avocado Smoothie- aids constipation

Avocado contains magnesium, a mineral that acts as a laxative by drawing water into the intestinal tract to keep things moving.  For a stomach soothing smoothie, blend 1/2 avocado, 1/2 cup raspberries, 1/2 cup unsweetened almond milk and some ice cubes.
