Kickstart your New Year’s health resolutions this month with these top nutrition tips from our Senior Dietitians at Blackrock Health Hermitage Clinic. Prioritise your health this year by following some simple guidelines:
– Prioritise whole foods: Swap processed snacks for nourishing, nutrient-dense snacks such as nuts and dried fruits, fruit and yogurt, cheese and crackers, nutty flapjacks, oat snacks. When opting for convenience snacks be aware of the ingredient list, some snacks which may label themselves as ‘healthy’ alternatives may have a long list of ingredients, generally the more whole ingredients and the shorter the list the better!
– Stay hydrated: Start each day with a glass of water and aim for 8 glasses throughout the day. Proper hydration is key for energy and overall well-being.
– Limit alcohol: Alcohol dehydrates and can cause fatigue which leads to poorer food choices as well as negatively impacting overall health. Swap alcoholic drinks for non-alcoholic alternatives where possible and aiming for at least three alcohol free days per week.
– Stay active: Incorporating some daily movement (outside if possible) will support overall mood, energy levels and health.
– Plan ahead: Try not let busy schedules derail your healthy eating goals. Meal prepping, batch cooking and planning snacks will help you stay on track.
At Blackrock Health, our Dietetics and Clinical Nutrition department is made up of Registered Dietitians who help manage and support a variety of nutritional and medical concerns to patients across our clinics.

What to know before grabbing an ice-cold beer to beat the heat:
It’s a warm summer day and you’re hanging out with friends and family for the first time in over a year, celebrating being vaccinated and just being together. And to help beat the heat, you reach in the cooler for an ice-cold beer.
While that might be refreshing at the moment, though, there’s good reason to grab some water, too. The heat of summer can be brutal, sometimes, and its effects are amplified when you’ve had a little too much alcohol.
To better understand the risks you face when drinking alcohol during this hot vaccine summer, we spoke with registered dietitian Julia Zumpano, RD.
The biggest danger: dehydration
Whenever you’re outside in the heat for prolonged periods – like at the beach or picnic – you’re at risk of dehydration. Consuming alcohol only heightens that risk.
Alcohol reduces the release of the hormone vasopressin, which keeps your body fluids balanced. At the same time, alcohol is also a diuretic which means more urinating and that can lead to dehydration even without the heat. Add in all that sweat from the hot sun and it’s a recipe for dehydration disaster.
One thing Zumprano points out, too, is that caffeine – whether via coffee, soda or as a mixer for liquor – heightens that dehydration risk even further.
Dehydration can also compound certain aspects of intoxication, she notes. “Altered thinking, altered abilities to drive and make reasonable decisions or even just to have conversations are all things that intoxication can cause.”
Liquor versus beer: Is one worse than the other in the heat?
Given that alcohol content is usually higher in spirits than in your average beer, it makes sense that drinking beer instead of mixed drinks might help you avoid dehydration. But the reality is a little more complex, according to Zumpano.
“If you’re consuming liquor at a volume equivalent to the volume of beer, like 12 ounces of margaritas compared to 12 ounces of an average beer, you will get drunk a lot quicker,” she says. “But if you’re drinking what’s considered an alcoholic drink equivalent, there’s not much of a difference because your alcohol intake is the same.”
According to the National Institute of Health, one alcoholic drink equivalent, also referred to as a “standard drink,” contains around 14 grams of pure alcohol. By those measurements, an average 12-ounce can of beer contains the same amount of alcohol as a 5-ounce glass of wine or a typical shot of distilled spirits like rum, vodka, gin or whiskey.
One thing to keep an eye on, though, is the alcoholic content of your beer. While major brands generally run between 4% and 5% alcohol per 12-ounce can or bottle, certain styles of craft beer are as much as 9% alcohol per the same volume. In other words, one can of your favorite local IPA delivers almost twice the amount of alcohol to your system.
Beware a false sense of hydration
Another mistake you should avoid, Zumpano says, is thinking that drinking all that liquid rehydrates you. “If you’re drinking a lot of beer or alcoholic seltzer, it can feel like you’re drinking a lot of liquid and staying hydrated, but the alcohol offsets that because it’s the dehydrating factor,” she points out.
Not that drinking mixed drinks is any better, according to Zumpano. “If you’re drinking a sugary, sweet mixed drink, you run into the same thing. It feels like you’re staying hydrated because they go down so much smoother than drinking spirits on the rocks. But it’s the same effect as with beer: The alcohol is still dehydrating you unless you’re also drinking enough water.”
Sugar, the hidden villain
All of these drinks have other adverse health effects, too. They can pack a bunch of calories into a single serving – as many as 400 to 500 calories in some mixed drinks and craft beers – and they can come loaded with carbs.
There’s more, though. “If you’re drinking high sugar, high caloric intake beverages and you’re drinking a lot of them, they can be very filling,” Zumpano says. If you’re feeling full, you might not eat any food which can otherwise help absorb some of the alcohol.
How to counter dehydration: water, water, water
So what can you do to avoid dehydration troubles when you’re sipping your favorite boozy beverage by the pool? “To counteract the dehydration risk of alcohol,” Zumpano says, “drink 8 to 12 ounces of water for every alcoholic drink. It slows your intake, keeps you hydrated and can mitigate negative hangover effects.”
She suggests keeping a reusable water bottle with you that you can refill as the day goes on, taking time to drink the necessary water between beers or margaritas. Another option is to buy a pack of 8-ounce bottles of water and alternate with your booze. And you can always infuse your water with fruit to keep it flavorful.
“It’s also important to know what your trigger for over-consumption is,” she adds. “If you’re triggered by over-consuming beer or alcoholic seltzer, you want to be mindful of that. Try to switch a drink you have better control of and keep the water bottle handy.”
Get your blood pressure checked at least once a year and understand what the numbers mean. Severe high blood pressure combined with symptoms such as chest pain or trouble speaking may be a hypertensive emergency, according to the new high blood pressure guideline, and you should call 911 immediately.

Daily stressors can increase BP in the moment, as well as contribute to habits that can feed long-term hypertension
Feeling stressed? If so, you’re hardly alone, given that stress has been called the health epidemic of the 21st century. But have you ever wondered what all this stress means for your blood pressure?
The answer, it turns out, is more complex than you might think. Let’s take a closer look with preventive cardiologist Luke Laffin, MD.
Does stress raise blood pressure?
Stressful moments can totally send your blood pressure (BP) skyrocketing. You feel it deep in your core, too, as your heart thumps harder and your nerves jangle with a fight-or-flight response.
“If we’re in a stressful situation, the normal physiologic response is to increase blood pressure,” explains Dr. Laffin. “But your body can handle these sorts of acute changes in blood pressure pretty well.”
And once the immediate stressor is gone, your BP should return to its typical level.
Of course, not all stress clocks out like it’s a shift worker. Chronic stress tends to linger — and that can contribute to a long list of physical symptoms, including high blood pressure (hypertension).
The connection between stress and hypertension
Researchers don’t know as much about the direct effects of long-term stress on blood pressure. But they do know that stress can impact lifestyle habits and increase your risk of heart disease and other chronic health issues.
“Stress itself doesn’t necessarily cause sustained elevations in blood pressure,” says Dr. Laffin. “But it often has an impact on lifestyle factors, which can absolutely contribute to long-term elevations in blood pressure.”
When you’re chronically stressed, you can fall into habits that can lead to higher blood pressure and increase your risk of heart disease. These include:
It can be difficult to see when acute stress transitions to chronic stress. But seemingly “temporary” stressors that last for weeks can turn into chronic stressors that need to be addressed for the sake of your heart health.
“What we’re really worried about is chronically elevated blood pressure,” states Dr. Laffin.
Can lowering stress lower your BP?
Finding ways to better manage your stress can help keep your blood pressure from rising and staying at elevated levels, suggests Dr. Laffin. He suggests:
Focusing on fitness: “Working out regularly is a great way to feel better, decrease stress levels and better adapt to difficult situations,” says Dr. Laffin. The positive effects of exercise on heart health are also important for your blood pressure.
Catching ZZZs: The quantity and quality of your sleep matter for your BP. “For stable blood pressure, you need to get about six to eight hours of uninterrupted sleep at night,” he advises.
Minimizing stressors: To reduce stress, you need to address its causes. Of course, that can be easier said than done when stressors involve your job or family. In these cases, additional steps, like therapy, may help you find coping strategies.
Adopting a heart-healthy diet: Foods high in sodium and saturated fats can increase blood pressure even before you add stress to the mix. Embracing a Mediterranean-style diet and eating more antioxidant-rich foods can help keep your BP down.
Calming techniques: Various forms of meditation can help you calm your mind and tamp down stress. There’s evidence that mindfulness-based stress reduction can lower BP within a few months.
Medications like beta-blockers may also be an option if stress seems to be driving blood pressure into danger zones. Antihypertensives can help bring down high blood pressure, too.
“But managing stress-related hypertension usually comes down to lifestyle,” clarifies Dr. Laffin. “Diet, exercise, sleep — those are all factors that play a big role in keeping your heart healthy.”

Excess alcohol and substance use can cause temporary and permanent memory loss
What are blackouts and brownouts?
Blackouts involve complete memory loss caused by your brain’s inability to record new memories for a period of time due to the effects of excessive alcohol, substance misuse or some other condition.
But sometimes, auditory or visual cues can help a person piece together memories of what happened during a blackout. These cues could come in the form of texts, pictures or conversations with people who were present while you were blacked out. The medical term for blackouts is called transient loss of consciousness (TLOC).
The difference between a brownout and a blackout is that brownouts involve partial memory loss. With a brownout, you may be able to remember certain details from the period of time you were affected, but other portions of time can’t be recalled.
“The hippocampus is a part of your brain that takes our experiences and the awareness of all our senses and processes those into memories,” explains Dr. Streem. “It’s sensitive, and it’s the same part of the brain that deteriorates in people with Alzheimer’s disease.”
Excessive alcohol use isn’t the only thing that can cause blackouts or brownouts. Substance misuse on its own or with alcohol can increase your likelihood of experiencing a blackout. Hypnotics or sedatives and benzodiazepines like flunitrazepam (also known as Rohypnol or roofies) can also lead to blackouts or brownouts.
There are other medical conditions that cause blackouts or brownouts, too, including:
“Anything that causes damage to the brain, whether temporary or permanent, can cause memory loss if the damage is in the right spot,” states Dr. Streem.
“When you’re passed out, you’re not awake. A blackout happens to someone who’s still conscious but they’re not coding any new memories,” explains Dr. Streem. “A person who has a blackout is still awake and they have some ability to think, but other parts of their brain may not be working well enough. Often, this is because of intoxication.”
Understanding these definitions and the difference between blackouts and passing out is incredibly important, as it may be difficult for other people to recognize someone is having a blackout because of their seemingly aware state.
How much alcohol can cause a blackout?
How much alcohol or substance use is needed to cause a blackout varies based on a person’s height, weight, sensitivity and assigned sex at birth.
“We know females absorb more alcohol in their bloodstream than males,” says Dr. Streem. “But for most people, it’s going to involve more than the legal blood alcohol limit. In almost all states in the U.S., the blood alcohol limit for driving is .08. Blackouts usually appear at blood alcohol levels that are twice the legal limit or higher.”
Studies have shown that young adults under the age of 25 are particularly vulnerable to experiencing blackouts. Additionally, blackouts may occur at far lower thresholds among younger populations. That’s largely because the parts of your brain responsible for decision-making aren’t fully matured until around age 25. Despite this, intentional binge drinking has been a common practice among young adults.
Regardless of age, recent studies show more frequent blackout experiences are related to an increase in memory lapse and cognitive difficulties even after alcohol misuse is corrected. This means that even after a blackout occurs, you can continue to experience memory loss and other difficulties recalling memories.
Blackout effects on your body
If you’re experiencing a blackout or brownout, you’re at higher risk for falling, injury and unwanted or unsafe sexual experiences. A person who is blacked out may also throw up while sleeping, which could lead to an increased risk of choking or suffocating.
It can be hard to determine when you’re going to have a blackout or brownout. But some signs it may be happening to you in the moment include:
Difficulty standing.
Nausea.
Lightheadedness.
Loss of vision or shrinking of your field of view.
Other signs of substance-related blackouts, specifically blackouts caused by sedatives, hypnotics or benzodiazepines, include:
Loss of bowel or bladder control.
Difficulty breathing.
Feeling drunk when you haven’t consumed alcohol or consumed less than your usual amount.
Sudden body temperature changes.
Sudden increase in dizziness, disorientation, loss of vision or difficulty speaking.
“Hypnotic drugs are prone to cause this kind of impairment and memory loss,” states Dr. Streem. “Sadly, people sometimes use them to take advantage of other people.”
Strategies for managing blackouts
A blackout ends when your body has absorbed the alcohol you consumed and your brain is able to make memories again. Sleep often helps this process along.
Alcohol is dehydrating by nature, so making sure you’re drinking plenty of water and staying hydrated is important. Being aware of potential signs of intoxication can also be helpful in understanding your limitations.
But what if you end up having a blackout anyway?
“The experience of a blackout can sometimes be an opportunity to learn about our bodies and our brains, and what we can and can’t handle,” says Dr. Streem. “But the most important thing to do when you have a blackout is to try and piece together as best we can what happened and whether we were injured. It also might be necessary to try to assess whether you’ve been taken advantage of in some way.”
If you think you’ve been injured, sexually or physically assaulted, it’s important that you get medical attention immediately and talk to the police about everything you can remember.
Other measures you can take to reduce the likelihood of blackouts and brownouts and increase your own safety include:
Drinking with people you trust.
Pairing up with a close friend or group of friends and leaving together.
Not drinking on an empty stomach.
Not taking drinks from other people.
Opening containers yourself or watching your drink being poured.
Taking your drink with you when leaving a room.
Not drinking anything that tastes or smells odd.
Asking for help when you start to feel drunk or intoxicated.
“There’s no way to prevent a blackout or brownout from happening other than to stop consuming so much alcohol or other substances that cause them,” says Dr. Streem. “Beyond that, safety and general physical care can be very helpful in making sure this doesn’t happen to you.”
