What to know about hydrogen water
Hydrogen-rich water, or simply 'hydrogen water,' is water infused with pressurized hydrogen gas. Some limited research suggests that drinking hydrogen water may have health benefits. This article describes what hydrogen water is in more detail. It also explores the possible health benefits and safety of hydrogen water. Finally, it answers some common questions about hydrogen is hydrogen water?As a 2024 review explains, hydrogen water is regular water infused with pressurized hydrogen gas. Because the hydrogen molecules are very small, they easily dissolve in the water, creating a hydrogen-rich solution. Research into the effects of hydrogen water on health is still in its early stages. However, early research suggests that hydrogen water has antioxidant and anti-inflammatory properties that may prove beneficial to health.»Learn more:The pH of water: What to knowPossible health benefits Below are some of the potential health benefits of hydrogen water:Antioxidant and anti-inflammatory propertiesA 2020 randomized controlled trial investigated the effects of hydrogen water consumption on oxidative stress and immune functioning in healthy term 'oxidative stress' refers to a state in which the body contains too many free radicals and too few antioxidants. Free radicals are unstable molecules that damage cells, whereas antioxidants are substances that neutralize free radicals and help protect against cell this 4-week trial, hydrogen water consumption decreased activity in an inflammatory pathway called the 'NF‑κB–pathway', reduced programmed cell death or 'apoptosis' in immune cells, and increased antioxidant levels in participants over 30 years of age. Improved exercise performance and recoveryA 2019 randomized controlled trial found that drinking hydrogen-rich water 10 minutes before exercise was associated with reduced fatigue and an increase in exercise authors concluded that hydrogen has antioxidant properties that appear to reduce oxidative damage and inflammation, both of which are ordinarily responsible for exercise-induced muscle metabolic healthEarly human trials suggest hydrogen water may modestly improve markers linked to metabolic health. A 2022 clinical trial investigated the effects of hydrogen water consumption on people with non‑alcoholic fatty liver disease (NAFLD). Compared to placebo, drinking hydrogen water for 8 weeks was associated with reduced liver fat and improvements in body weight and body mass index (BMI). However, more research is a 2023 meta-analysis of seven clinical trials reported that hydrogen water consumption was associated with small but significant improvements in levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides. The study authors concluded that drinking hydrogen water can significantly improve lipid levels, though further studies are needed to confirm these against the effects of aging A 2021 randomized controlled pilot trial investigated the effects of a 6-month intake of hydrogen water on markers of aging in adults ages 70 years or above. The experimental group received hydrogen water, while the placebo group received regular to placebo, hydrogen water consumption was associated with an increase in telomere length. Telomeres are protective structures that sit at the end of chromosomes, and they shorten with each cell division. This shortening is associated with aging and age-related hydrogen water safe?Hydrogen water is one type of molecular hydrogen therapy (MHT), with other examples including inhalation of hydrogen gas and injections of hydrogen-rich saline.A 2023 review of more than 80 clinical trials on MHT reports good tolerability and notes that serious adverse effects are 2014, the Food and Drug Administration (FDA) has listed hydrogen gas on its Generally Recognized as Safe list. The listing indicates that hydrogen is safe as an ingredient in beverages with a volume of up to 2.14%.Frequently asked questions How do people make hydrogen water?A person can make hydrogen water by dissolving hydrogen-rich tablets in regular water, or by using a device called a hydrogen water generator to infuse regular water with hydrogen gas.A person can make hydrogen water by dissolving hydrogen-rich tablets in regular water, or by using a device called a hydrogen water generator to infuse regular water with hydrogen regular water healthier than hydrogen water?Some research suggests that hydrogen water may have greater health benefits than regular water.

5 Flavonol-Rich Foods You Should Be Eating More Of, According to Dietitians
Reviewed by Dietitian Katey Davidson, RD, CPTKey Points Flavonols are plant compounds with antioxidant and anti-inflammatory properties. Top sources of flavonols include citrus fruits, onions, dark chocolate, apples, herbs and spices. Eat a variety of colorful fruits and vegetables for an anti-inflammatory may know that the foods you eat contain macronutrients like carbs, fats and protein, as well as important vitamins and minerals. But you may not be as familiar with flavonols—plant compounds with antioxidant and anti-inflammatory properties that help your body defend against chronic disease. Flavonols belong to a larger family called flavonoids, which also includes compounds such as flavones, anthocyanins and catechins. "Flavonols are important for heart health, brain function, supporting memory, as well as reducing chronic inflammation, linked to diabetes, heart disease and arthritis," notes Val Goldberg Libraty, RD, CD, a registered dug into the research and spoke with registered dietitians to find out the top food sources of flavonols, why they're so good for you and tips for eating an anti-inflammatory diet. Citrus Fruits Citrus doesn't just bring bright, zesty flavor to foods and drinks—they're also packed with nutrition. "Citrus fruits, such as oranges and grapefruits, are not only rich in vitamin C but also in flavonols, which are mainly found in the membranes and pulp, protecting against oxidative stress and supporting immune system function," states Johane Filemon, RDN, a registered dietitian specializing in chronic inflammation and gut has found the flavonols and flavones found in citrus fruits—such as luteolin and apigenin—act as antioxidants in your body, helping to reduce inflammation. These compounds are also known to offer antimicrobial and anticancer properties. To get more in your diet, reach for tangerines, oranges, grapefruits, lemons and limes. Dark Chocolate It's a win-win when nutrition research supports a food most of us love. Frances Largeman-Roth, RDN, notes that "dark chocolate and cacao nibs are a fave. They are rich in epicatechins and procyanidins."Cacao—the plant behind chocolate—contains a mix of flavonoids, including quercetin and anthocyanins, along with an alkaloid known as theobromine. These compounds are linked to a reduced risk of certain chronic diseases, such as heart disease, type 2 diabetes, obesity, cognitive decline and certain types of cancer. "Research has linked dark chocolate consumption with improved endothelial function and lower blood pressure," explains Largeman-Roth. Cacao also has some fiber and minerals, such as magnesium and potassium. Dark chocolate contains a higher percentage of cocoa solids—often 70% or more—which helps deliver these health benefits. Cacao nibs, being minimally processed, retain the most nutritive value. Plus, both options are often lower in sugar than milk chocolate, making them a better choice when trying to get your chocolate fix. Herbs and Spices Herbs and spices add more than just flavor to your meals—they also support your health. Many flavonoid-rich herbs and spices may support heart and gut health and help stabilize blood sugar levels. Libraty recommends spices like cinnamon, turmeric and garlic for their antioxidant activity. But don't overlook herbs like parsley, often thought of as just a garnish. Filemon notes that parsley is "rich in kaempferol, as well as quercetin, two antioxidants known for their anti-inflammatory properties." It also adds lots of freshness in recipes like tabbouleh and salad dressings. Whichever herbs or spices you choose, you're likely going to get some health-supporting benefits. Plus, they're great for adding flavor when you're trying to limit extra calories and sodium. Apples Apples are one of the most popular fruits for a reason—they're full of nutrition and easy to access. Largeman-Roth remarks, "I also am a fan of apples thanks to their quercetin content, which helps protect our brains and provides cardiovascular benefits."If you want to stay strong as you age, you may want to reach for apples and other quercetin-rich foods. A recent study found that a high intake of quercetin was associated with a lower risk of frailty. "Apples are also a source of soluble fiber, making them a top choice as a filling and nutritious snack," says Largeman-Roth. Onions You've probably heard the advice to "eat the rainbow," since the compounds that give fruits and vegetables their beautiful colors are often the same ones tied to health benefits. But this also includes lighter-colored vegetables, like the humble white or yellow onion, which are also rich in flavonols. "Onions are a kitchen staple in my home, not only for the flavor but also due to their high quercetin content, a flavonol that has been linked to reducing inflammation and cellular protection," says are packed with flavonoids known for their anti-inflammatory effects, and potential benefits for blood sugar and cholesterol management. They're flavorful, affordable and versatile—just a few more reasons to love this everyday powerhouse. Other Tips for an Anti-Inflammatory Diet Eating foods that are rich in flavonols is important for reducing inflammation, but your overall dietary patterns and habits are key. A diet full of fruits, vegetables, whole grains, healthy fats, proteins, nuts, seeds and legumes delivers many powerful anti-inflammatory nutrients. It's important to combine that with other healthy lifestyle habits, like physical activity, social connection and limiting stress. These tips can help too: Sip on coffee and green tea. What you eat is important, but so is what you drink. Coffee and tea are rich in antioxidants that may support brain health and concentration. Largeman-Roth says, "Green tea is one of the richest sources of catechins and has been linked to brain protection and cardiovascular benefits. Drinking a cup of green tea daily is a very smart health habit." Go for color. The more colorful your meals, the better. Different fruits and vegetables offer a variety of flavonoids, which help reduce inflammation. "The more colorful your plate is, the more nutrients you are including," explains Filemon. Decrease ultra-processed foods. If you're looking to lower inflammation, reducing ultra-processed foods that are high in added sugar, sodium, saturated fats and refined grains is a smart place to start. Eat a variety of foods. While we've highlighted five top sources of flavonols, it's important to remember that every food has its own unique nutrient profile. You'll get different benefits from cherries than you would from kale or almonds—but it doesn't necessarily make one better than the other. "Eating a variety of foods is important for getting as many inflammation-fighting foods in your diet as possible," points out Largeman-Roth. Our Expert Take Flavonols are plant compounds linked to reduced inflammation and a lower risk of chronic disease. Foods that are rich in flavonols—like onions, apples, citrus, chocolate, herbs and spices—also provide other nutrients that are important for overall health. You don't need to overthink it when it comes to flavonols. Just aim for a variety of different colorful fruits and vegetables and occasionally challenge yourself to try something new."The first step in any wellness journey is starting with the basics," says Filemon. "Making your plate around fiber-rich, colorful produce and healthy fats is an easy change to make to reduce inflammation and promote good gut health." Read the original article on EATINGWELL

I changed my whole diet to conquer Samsung's antioxidant index; here's how it works
When you buy through links on our articles, Future and its syndication partners may earn a commission. One of the few Galaxy Watch 8 exclusives is its antioxidant index, which measures nutrients through your skin to determine whether you're eating healthily. I took it personally when Samsung estimated that I had "Low" antioxidants, so I spent the past week eating as healthily as possible to see if it made a difference. Samsung's multicolored health sensors look for carotenoids, the pigment that gives fruits and veggies their bright red, orange, or yellow coloring; once in your body, they counterbalance the "oxidative stress" generated from poor lifestyle habits like smoking, drinking, overeating, and stress. Hence the name "antioxidants." Generally speaking, the antioxidant index is intended to determine whether you're consuming your WHO-recommended 400g of fruits and vegetables per day. For health-conscious individuals who dislike logging their food daily, the Galaxy Watch 8 offers valuable context. But since I thought I was eating healthily enough, I decided to cram carotenoid-rich foods into my diet for a week to see whether Samsung would be able to detect the changes properly. How the Antioxidant Index score works on the Galaxy Watch 8 Your body stores carotenoids in the skin, where the Galaxy Watch 8's optical sensors can spot and measure them. Samsung told TechRadar that your wrist has too many capillaries, so your blood confuses the results; pressing your thumb against the sensor will "push away all the blood" and make it easier to check your carotenoid levels. Carotenoids are just one type of antioxidant, but their pigmentation allows Samsung to detect them. We've emailed Samsung to ask if it might eventually track other antioxidants, but for now, carotenoids are the best estimate to check non-invasively if your body has other healthy vitamins and nutrients. So, what foods have carotenoids? Samsung suggests root vegetables (carrots, sweet potatoes), leafy greens (spinach, kale), citrus fruits (oranges, mangoes), tomatoes, and bell peppers. Other carotenoid-rich foods include pumpkin, squash, cantaloupe, and corn; most red, orange, and yellow produce will likely have some. Samsung used data from clinical trials at Samsung Seoul Hospital to determine the "correlation between fruit and vegetable intake and the accumulation of carotenoids in the skin." Adequate antioxidant levels get a score of 75–100. People with "Low" scores (50–75) consume 50–99% of the recommended daily amount, so about a 2% increase per point. Very Low (0–49) is "less than 50%." Samsung also warns that your score may fall during "periods of severe stress or when drinking or smoking," so it's about lifestyle as much as nutrition. The company says it may change the criteria with "future clinical results," but the gist is that you want a score of 75 to match recommended levels. Everything above that is just gravy, while lower scores leave you vulnerable to "cell damage, excessive aging, inflammation, worsening eyesight, and chronic diseases such as cancer" over time. Raising my Antioxidant Index score on my Galaxy Watch 8 Samsung warns that it can take "up to 2 weeks for your antioxidant index to reflect an increased intake of fruits and vegetables," so I knew that eating a boatload of carotenoids wouldn't instantly level me up. But I wanted to see if there was an obvious impact from a changed diet in the short term. I stuck to my normal diet for the first day, and my reading stayed consistent. Starting on Monday, I raided my grocery store for carotenoid-rich fruits and veggies, then spent the next five days eating salads, bell peppers, cantaloupe, and other healthy produce, well above the recommended five servings per day. My score did start to course-correct, but slowly. I looked into the benefits of raw vs. cooked veggies and realized that raw vegetables are high in vitamins and fiber but low in beta-carotenes. You get the most carotenoids from cooked vegetables paired with healthy fats, like cooking oil. I'm more of a raw veggies guy than a stir-fry guy, which may be part of my problem. So I tried to incorporate more cooked veggies, paired with meats or peanut butter, during the final stretch. Sunday Monday Tuesday Wednesday Thursday Friday Saturday 54 53 56 65 61 65 65 I climbed from an antioxidant index score of 53 (56% of recommended antioxidants) to 65 (80%) in a week. In theory, one more week of healthy eating will bring me to my target score of 75, on pace with Samsung's two-week estimate. I can't quantify how accurate Samsung's antioxidant index is without a blood test, but this experience did, at least, show that this sensor isn't just some pseudoscientific guesstimate. It can tell that I'm eating healthier. On the other hand, it feels demoralizing that my antioxidant index score has stalled out in the last few days, despite eating so healthily. I could have cheated and taken dietary supplements to raise my score, but Samsung warns that these can have "harmful side effects" and "increase your risk for cancer and heart disease," so you and I should stick to the healthy-eating path. The main problem with Samsung's antioxidant index Most Android watches have food logging in their apps, but I dislike calorie-counting and having to quantify every meal. I do care about eating healthy, however, and only the Galaxy Watch 8 and Galaxy Watch Ultra have a tool like this, thanks to the BioActive sensor. I'm glad to have this tool as a baseline for my health. Here's the main issue with the antioxidant index: there are more antioxidants than just carotenoids. Other types, such as flavonoids, polyphenols, and lycopene, are found in a wide range of fruits, vegetables, beans, and teas, and they all help remove the "free radical" molecules that contribute to aging and disease. Carotenoids are a key indicator of your health, one that helped me recognize a dietary deficiency. However, since Samsung cannot track other non-pigmented antioxidants as easily, your actual "antioxidant score" might be higher than Samsung can accurately assess with a smartwatch. But this isn't a criticism! It's merely a reminder that you shouldn't ignore the healthy foods that don't have carotenoids just because Samsung doesn't reward you for eating them. The Samsung Galaxy Watch 8 uses its BioActive sensor to track several new metrics, including your circadian rhythm for Bedtime Guidance, Vascular Load for heart health and stress, and the aforementioned antioxidant index. It's a fast smartwatch with valuable health and fitness insights. View Deal The Samsung Galaxy Watch 8 Classic has the same BioActive sensors as the Watch 8, but with a stainless steel case, rotating bezel for exact controls, doubled storage, and a third Quick Button for shortcuts. Choose this option if you care about eating healthy and looking more stylish. View Deal
