Key takeaways:

Too much caffeine can lead to headaches, vomiting, diarrhea, chest pain, high blood pressure and hyperactivity. For kids, this can impact schoolwork and athletics.

Everyone responds to caffeine differently. But a general rule for young people: limit daily caffeine consumption to 2.5 milligrams per kilogram of body weight.

Adults should watch what kids are drinking, how often and how they respond. If you have significant symptoms of a caffeine overdose, call 9-1-1.

Urbana - United States Sen. Chuck Schumer is asking the Food and Drug Administration (FDA) to look into PRIME Energy drinks, a product of entertainers Logan Paul and KSI. The senator claims the drinks are high in caffeine and are marketed to children, possibly leading to dangerous health outcomes. The people behind PRIME have defended the product.

Politics aside, the issue of what young people put in their bodies is something to be aware of, says Michael Broman, PhD, MD, an OSF HealthCare cardiologist. In fact, it’s one he thinks about daily.

“My children are 8 and 10. I don’t allow them to have caffeine except under my supervision and only in very small doses,” Dr. Broman says sternly.

Caffeine basics

Dr. Broman says energy drinks, when consumed properly, can provide the desired energy boost. A college student studying for a test, for example.

But it’s caffeine consumption that you must be aware of.

“Caffeine has clearly been linked to adverse events and toxicity when given at a high enough dose,” Dr. Broman says.

The effects of caffeine will vary from person to person. Some will be more sensitive to caffeine due to genetics. Others may be able to break down caffeine more quickly, meaning less sensitivity.

Generally though, Dr. Broman says taking in too much caffeine could lead to your heart racing, nausea, vomiting, diarrhea, chest pain and high blood pressure. You may also feel hyper and not able to sit still.

“Caffeine also causes dependence,” Dr. Broman adds. “As a person uses more and more over time, they start to miss it when they don’t have it. They can withdraw from caffeine.

“That’s one of the most worrisome side effects, especially in kids. If a child is using a lot of caffeine and they stop, they can have attention problems and headaches. It can affect their performance in school and athletics.”

What to know

Here’s the formula to remember: Dr. Broman says for children and adolescents, limit daily caffeine consumption to 2.5 milligrams per kilogram of body weight. (You can easily find a pounds to kilograms converter online.)

For example, if a high school student weighs 120 pounds (or around 54 kilograms), they would want to stick to 135 milligrams of caffeine per day. One PRIME Energy drink has 200 milligrams of caffeine. A 20-ounce bottle of Coca Cola has 57 milligrams. Caffeine content in coffee can vary. So be vigilant about your health and seek out the numbers. Check the product label or look up the product online before you swing by the drive thru or go to the store.

The formula, though, doesn’t mean two bottles of Coke or a half swig of PRIME per day will yield no consequences for a 120-pound teenager. Rather, Dr. Broman recommends people under 18 not ingest caffeine regularly at all. Parents, teachers and coaches should watch what young people are drinking. Make the energy drink or soda a once-in-a-while treat. Water flavored with fresh fruit can be an alternative or talk to a dietitian about what’s right for you.

“A lot of these caffeinated beverages are marketed and flavored to taste good for children,” Dr. Broman says. “The drinks may also be in the store displays right next to the non-caffeinated beverages. They can look almost the same. So, it’s often difficult for a young person to figure out, ‘Is this beverage caffeinated? Is this one non-caffeinated?’”

And remember, everyone reacts to caffeine differently. Like any other ailment, know your health history and how your body responds to things. If you have significant symptoms from a caffeine overdose, call 9-1-1 and take an ambulance to the emergency department.

“People with prior cardiac conditions are way more likely to have very dangerous side effects from the use of caffeine,” Dr. Broman says.

Exposing misconceptions about infant nutrition for new moms

DANVILLE - Bringing a new baby home raises the focus on their and mom’s well-being. Toward the top of the list: what and how the child is being fed.

Whether you choose to breastfeed or use formula, misconceptions about infant nutrition are everywhere. Xandra Anderson, a certified lactation consultant at OSF HealthCare, cuts through the noise.

Do I need to change what I put in my body while breastfeeding? This covers a lot of ground, from a mom’s diet to whether she should abstain from alcohol, caffeine, tobacco and medication.

Breastfeeding moms generally don't need to change their diet. Drinking a caffeine-heavy drink before breastfeeding may keep your baby awake longer than normal. After drinking alcohol, wait a few hours to nurse.
Moms can also generally stay on medication while breastfeeding. Talk to your health care provider if you have questions or if you have a medical procedure.
If you smoke, do so after breastfeeding. Then wait a few hours to nurse again.
Have breast milk you can't use in feeding? Use it on baby acne or in their bathwater.

Do I need to change what I put in my body while breastfeeding? This covers a lot of ground, from a mom’s diet to whether she should abstain from alcohol, caffeine, tobacco and medication.

Diet:

Healthy eating is always good. But Anderson says new moms generally don’t have to change their diet for breastfeeding. If your diet is heavy on certain things (like garlic or dairy) and you notice your baby is extra fussy, you can try changing your meals. A provider may also want to test your baby for allergies.

Alcohol and caffeine:

Drink these in moderation and with precise timing, Anderson says.

“Babies are very sensitive to caffeine. If you have a cup of coffee and nurse right away, the baby is going to be awake for a lot longer than normal,” Anderson explained.

“That doesn’t mean you have to not drink coffee. Just maybe not add three shots of espresso to your morning coffee,” she adds with a smirk.

For alcohol, Anderson says the drink will filter out of your breastmilk like it filters out of your blood. So after having a couple of alcoholic drinks, wait two to three hours before breastfeeding or pumping.

“The breastmilk isn’t ruined. You just need to give it time,” Anderson says.

But here’s a lifehack if mom feels full of breast milk and wants to pump right after having a drink: Go ahead and pump, and use the milk on your baby’s acne or in their bathwater. Just keep it away from their mouth.

“It’s antimicrobial. It’s antibacterial. It’s moisturizing,” Anderson says, singing the praises of breast milk. “Our babies are in the most perfect environment in the womb. Once they’re born, their world is cold, dark and dry. They can get dry skin, acne or cradle cap [greasy or flaky spots on the scalp]. Breast milk is a great way to prevent or heal those things.”

Medication and other health care issues:

Anderson says most medication is safe to use while breastfeeding. In fact, it’s important to stay the course – for example, with mental health medication – so you can be the best mom possible. Talk with your health care provider if you have questions.

If you have a medical procedure, also get advice from a professional. For example, Anderson says if you get a hepatobiliary iminodiacetic acid (HIDA) scan for a gallbladder concern, you’ll be radioactive for around 24 hours. Don’t breastfeed during that time. Or if your breasts feel full and you have to pump, dump the milk down the drain.

Tobacco:

Anderson admits it’s tough to kick the habit. But she reminds moms: infants are very sensitive to nicotine. It can disrupt the child’s sleep and feeding and even interfere with organ development. Secondhand smoke can increase the risk of a respiratory infection and sudden infant death syndrome (SIDS).

If you’re smoking with a new baby at home, do so after breastfeeding, then wait two to three hours before nursing again. Wear one jacket while smoking so you don’t get an odor or residue on a lot of your clothes or the baby.

Drinking three or more cups of green tea a day has been proven to maintain and improve cardiovascular health.

PEORIA - So, what’s the tea?

You may have heard that tea is good for you, but when walking through the grocery aisle and being confronted by a barrage of options, it can be hard to choose.

Ashley Simper, the manager of dietetic services with OSF HealthCare, has done the research and has some helpful guidance.

To start, it’s best to understand the different kinds of teas and where they come from. Simper says black, white, oolong and green tea all come from the Camellia sinensis plant. Herbal teas come from root, stems and flowers of various plants, and they all have different benefits.

What’s the overall healthiest tea?

Overall, Simper says green tea shines above the rest. But diving into the specific benefits of each tea can help people choose what’s right for them.

“Consuming three or more cups of green tea a day leads to the most health benefits when it comes to cardiovascular disease, cancer and the overall risk of mortality,” Simper says. “The research is a little stronger when it comes to promoting heart health. The consumption of three to five cups of green tea a day has also been shown to lower blood pressure, stroke risk, and LDL (bad cholesterol),” Simper says.

Consuming three to five cups of green tea or black tea has also been shown to lower the risk of developing diabetes.

In 2022, a large study in the Annals of Internal Medicine showed that drinking black tea resulted in a modest reduction of overall death. A research team from the National Institutes of Health’s (NIH) National Cancer Institute (NCI) investigated roughly half a million adults, ages 40-60, in the United Kingdom (UK), who enrolled in the UK Biobank study between 2006-2010. The researchers followed participants until 2020 and found a 9-13% lower risk of death among people who drank at least two cups of tea per day than non-tea drinkers.

What makes tea so healthy?

“The compound in tea that leads to these health benefits is polyphenols. Polyphenols are a type of antioxidant, and antioxidants are linked to decreased inflammation and reduced risk of chronic disease,” Simper says. “The highest antioxidant compounds are in the green tea, followed by the oolong, black and then white teas.”

She adds that green tea and white tea contain an amino acid called L-theanine. Amino acids are the “building blocks” of protein, Simper adds.

“L-theanine has been linked to decreased anxiety, improved sleep and boosting mental clarity,” Simper says.

Green tea, high in antioxidants, offers the most health benefits. In beverage or dietary supplement form, it has been linked to improved mental alertness, relieving digestive issues and headaches, and assist with weight loss.

Cancer: Mixed reviews, additional safety tips

“When it comes to cancer, the research is conflicting. People who drank higher amounts of green tea had a decreased risk of liver, ovarian, lung and breast cancers. But it is important to keep in mind, that if you’re drinking really hot tea, you have a higher risk of esophageal and gastric cancers,” Simper says.

To avoid the tea being scalding hot, Simper recommends allowing the just-boiled water to cool down for an appropriate amount of time before taking a sip.

Tea’s impact on the flu

“In lab and animal studies, they have found an antiviral effect with the consumption of green tea. In Japan, they did a study with kids that showed anywhere from one to five cups of green tea a day lowered the risk of flu,” Simper says. “There was also a study where they gargled green tea in a bottle, green tea extract or black tea extract, and there was a 30% decreased risk of flu.”

How to prepare your tea

As Simper mentioned, scalding hot tea can come with its own risks, more than just burning your mouth. But there are other ways, she says, to make sure you’re receiving the most benefit from drinking tea.

“They recommend boiling your own water and steeping it yourself instead of putting the water in the microwave to heat it up. They found you lose some health benefits if you microwave the water in your tea. Fresh is best, steep your own, and boil your own water. But let it cool down to a comfortable temperature before you consume it. “Freshly brewed tea with minimal additives, especially things like sugar and milk, is the way to go when it comes to adding tea to your daily intake,” Simper adds.

Benefits of herbal teas

Depending on which symptoms you’re dealing with, or health benefit you’re looking for, different herbal teas have different purposes.

Peppermint teas – Helps with upset stomach

Ginger tea – Helps with nausea

Chamomile teas – Can help decrease cardiovascular disease and some cancers. It can also help with premenstrual syndrome and help boost immunity, Simper says.

But what about all the caffeine?

“The caffeine in tea is about half the amount of coffee. You would have to drink eight or more cups of tea a day to get to that highest level we would recommend for caffeine. So, it’s not that much of a risk for people,” Simper points out. “However, if you’re going to start drinking three to five cups of tea a day, and you’re not normally a caffeine consumer, you might notice the effects of the caffeine.”

Connection to weight loss

If you’re looking to tea for weight loss, you might be waiting for some time, Simper says. She says the research is conflicting, and weight loss is minimal due to drinking tea. However, switching out caffeinated tea for sodas and coffees filled with sugar would be the healthier choice.

Daylight Savings Time is coming, start preparing your body for time change

Family Features - Millions of Americans will soon get extra sunlight in the evenings when daylight saving time (DST) - observed by every state except Arizona and Hawaii - begins on the second Sunday in March and clocks are set ahead by one hour at 2 a.m.

While the extra daylight is a welcome change for most, failing to prepare for DST can have consequences. In fact, research from the Sleep Foundation has found a lack of sleep caused by the time change can affect thinking, decision-making and productivity. The change can alter your circadian rhythm, the body's internal clock that helps control sleep and other biological processes, which may cause mood fluctuations, and the transition has been associated with short-term risk of heart attack, stroke and traffic accidents.

However, making small adjustments ahead of DST can help reduce its impact on your sleep and minimize negative effects. Consider these tips to help navigate the time change.

Reset Your Internal Clock
As you get ready to "spring forward," gradually adjust your sleep schedule throughout the week leading up to the time change, which can help prevent unnecessary shock to your system. The American Academy of Sleep recommends going to bed 15-20 minutes earlier each day than normal, and other daily activities like mealtimes and exercise can also be moved up slightly to help acclimate to the change. Awakening earlier and getting extra light exposure in the morning can also help adjust your circadian rhythm.

Upgrade Your Sleep Environment
Creating a bedroom environment that is conducive to sleep can help ensure you get a good night's rest, which is especially important leading up to the time change when you effectively lose an hour of sleep. Start optimizing your sleep space comfort by choosing a supportive mattress and comfortable bedding then block out unwanted light with blackout curtains and dampen unwanted noises using a fan or soothing white noise machine.

To help regulate temperature, set the thermostat to 60-70 F - a cooler thermostat setting helps maintain a lower core temperature - then adjust if too hot or too cold by adding or removing blankets or changing your pajamas. Lavender essential oils, or another fragrance like peppermint or heliotropin, can also help improve relaxation and sleep quality.

Avoid Screens Before Bed
In the days leading up to DST, experts recommend turning off electronics, including televisions, computers, smartphones and tablets, at least 1 hour before bedtime as the blue light from screens can suppress production of melatonin, the substance that signals the body it's time for bed. If necessary, cut back on screentime in smaller increments leading up to the time change or swap evening screen usage for other activities like crossword puzzles, meditation or reading a book.

Phase Out Caffeine in the Evenings
While avoiding caffeine later in the day can help you fall asleep easier at night, experts suggest limiting and slowly reducing your caffeine intake in the days prior to DST. Choosing half-caffeinated coffee, mixing regular and decaf or cutting out 1-2 caffeinated drinks during the week can help sleep patterns ahead of the change. However, be wary that giving up caffeine "cold turkey" can sometimes lead to headaches.

Pre-workout supplements not for teen and youth athletes, a healthy diet is safer

The question is should middle- or high school-aged kids use these supplements? The answer: Probably not.

PEORIA - Did you have a childhood hero? If so, you likely aspired to emulate them and their achievements.

Nowadays, your kids may see their favorite athlete or influencer using pre-workout supplements, whether on social media or in stores, to enhance their performance in the gym or on the field.

What are pre-workout supplements?

Pre-workout supplements come in various names, flavors, and sizes. Some popular options are creatine and branched-chain amino acids (BCAA). While creatine and the main ingredient in most pre-workout supplements is caffeine, most BCAAs don’t contain caffeine.

These supplements are taken before a workout or athletic match with the goals of increasing endurance, muscle mass, and reducing recovery time. But the question is should middle- or high school-aged kids use these supplements? The answer: Probably not.

What are the risks of pre-workout supplements?

“These can cause increased heart rate or heart burn. You’re also taking a lot of supplements that are going straight to your gut. You can see some nausea, vomiting, diarrhea or constipation. They’re also not well-monitored, the U.S. Food & Drug Administration (FDA) isn’t regulating these very closely,” says Erica Dawkins, a dietetic intern with OSF HealthCare.

Taking it further, kids with heart defects need to steer clear of these supplements.

“A lot of times we see defects or heart irregularities that somebody isn’t even aware of. They don’t know that until they take something like this and have an adverse event,” Dawkins says. “So, if you already know, avoid these because we don’t want to throw that heart into an abnormal rhythm it might not be able to come back from.”

What are the benefits of pre-workout supplements?

“A lot of them will already have beta-alanine or branched-chain amino acids which help improve recovery time and reduce fatigue,” Dawkins says. “We also see some nitrates used that help improve blood flow to the muscles.”

Most pre-workouts are intended for healthy adults in moderation. Pregnant and nursing women are generally advised to avoid them due to the high caffeine content.

“Focus first on making sure you’re having quality workouts, then introduce healthy nutrition,” Dawkins says. “We want to make sure we’re getting that nutrition throughout the day. Especially if we’re working out multiple times throughout the day. If you’re working out within two to four hours, make sure you’re getting a snack. We see a lot of benefits for pre-workout snacks or snacks during half-time. We also want to make sure we’re staying adequately hydrated.”

Dawkins says leafy and root vegetables like spinach, lettuce and beets are a great, natural option.

“Those have the natural nitrate in it. So, we’re getting the same effects we would from a pre-workout supplement, just in our regular diet,” Dawkins adds.

Having a conversation with your child’s pediatrician or sports medicine physician is extremely important if you are wondering what supplements should or should not be added into their routine.

Creatine: Kicking your fitness level up a notch or two, it can work for you

In the sports world, victory can be just inches or seconds away.

Dr. Karan Rai

BLOOMINGTON - Think about ‘The Longest Yard’ in Super Bowl 34 between the Tennessee Titans and St. Louis Rams. In the final play of the game, one yard was all that stood between the Titans and the Vince Lombardi Trophy.

Or look at the 2024 Summer Olympics! Noah Lyles earned the United States a gold medal after winning by just five thousandths of a second in the 100-meter final.

Athletes look for game changers to help propel themselves ahead of the competition, and creatine has entered the chat.

Who does creatine work for?

“Creatine, when used appropriately, can improve your max power. It can help with muscle growth in certain individuals, it typically does not have as significant of an impact when you're doing more endurance-based sports," says Karan Rai, MD, a sports medicine physician with OSF HealthCare. "If you're a weekend warrior or CrossFit athlete trying to get a little extra boost, while practicing appropriate hydration and dietary intake, I think creatine has benefits.”

Dr. Rai adds that in the realm of supplements, creatine has been “decently studied over the years.” He says football players, power lifters and track sprinters could benefit from the supplement. However, if you’re training for an upcoming Ironman or triathlon, it’s really not necessary.

Hydrate, hydrate, hydrate!

It’s no surprise that extreme exercise increases the amount we sweat. With or without creatine, that’s reason enough to up your water intake. But Dr. Rai says with creatine, there’s an added reason to why water is so important.

“Commonly I'll find someone who is new to using a supplement and they'll come see me and talk about muscle cramps or excessive fatigue after their workouts,” Dr. Rai says. Oftentimes it's because of an imbalance in their intake, whether that's food intake or hydration."

If you already cramp constantly or are not as experienced in weight training, Dr. Rai would recommend caution in using creatine. He says to talk to your primary care physician or a sports medicine physician to see if creatine is a beneficial option for you.

Best times to use creatine

Before and/or after your workouts are times Dr. Rai recommends taking creatine. He says like most dietary changes, don’t rush it.

"When someone is using creatine, I recommend they start slowly. Typically, utilizing it before the workout and making sure your workout is power based vs. endurance-based matters," Dr. Rai says. “Just starting off, depending on the serving size, use one to two scoops.”

Careful with the caffeine!

Avoid a ton of caffeine consumption if you're using creatine. Caffeine can elevate the heart rate and creatine can cause cramping, so combining those things could lead to "adverse outcomes," Dr. Rai says.

"Supplements are meant for augmentation," Dr. Rai adds. “A healthy diet, hydrating appropriately while cultivating your goals, whether you're a power or endurance athlete, gives the max benefit. Really we should be looking at creatine or sports drinks as a way to augment and get that extra 5-10% we are pushing for, based off our goals.”

If you’re looking to add creatine to your lifestyle, Dr. Rai recommends creating an individualized plan with your doctor or sports medicine team.

Due to limited data, the American Academy of Pediatrics does not recommend creatine for kids under 18.
