Keys to Good Health

You hear lots of advice from many sources about what it takes to live well and keep your body in good working order. Sorting out what that means for you could seem like an overwhelming task. Let’s break it down into a few simple, easy-to-remember ways for adults to stay on a healthy path.

Become a flexitarian.

Numerous studies have shown that a plant-based diet is healthiest, but you can still get many of the benefits even if you don’t go full-on vegetarian. Following a semi-vegetarian diet that includes fewer animal products but doesn’t completely cut them out may help you keep your weight in check as well as lower your chances of high blood pressure, type 2 diabetes, and inflammatory bowel disease.

Expand your palate’s palette.

Dietary guidelines recommend that half of what’s on your plate at any meal be vegetables or fruits. But it’s also important to mix things up. While all fruits and veggies are healthy, they don’t all have the same nutrients. Give yourself the widest range of benefits by eating different-colored produce throughout the day.

Less sugar, more water.

It’s a good idea to avoid added sugar in whatever you eat, yet soda, sports drinks, and energy drinks may be a bigger source than you realize. Some studies show that just a soft drink or two a day makes you 26% more likely to get type 2 diabetes. Sugary drinks have also been tied to heart attacks, gout, and obesity. Stay hydrated with water or, if you miss the fizz and taste, naturally flavored seltzer.

Move more, sit less.

That’s the physical activity guidelines in a nutshell. While at least 150 minutes a week of moderate exercise is ideal, experts say that any movement is better than nothing. So make it a point to stand up more often and stretch, park a bit farther from your destination for extra steps, and explore new pastimes that will help put you in motion.

Get enough rest.

Sleep is often low on the list in our nonstop society, but it’s a must for good health. Chronic sleep deprivation raises the odds for heart disease, diabetes, stroke, obesity, and many other sicknesses. Getting your ZZZs also helps keep you safe: Driving while sleepy is just as bad as driving drunk. If you don’t usually wake up feeling refreshed, try slipping into bed 15 minutes earlier every week until you do.

Tame your stress.

Everyone has stress; it’s how you react to it that matters. When you often explode in anger, get stomachaches because you’re nervous, or have trouble sleeping because you’re anxious, it’s time to make a change. Find a way to blow off steam, whether that’s through exercise, meditation, or laughing with good friends. Still feeling overwhelmed? Make an appointment with a counselor or other mental health professional.

Wash your hands.

It’s one of the easiest and most effective ways to avoid catching whatever contagious bugs are going around. The key is to be thorough: After you lather up with soap, scrub your palms, the backs of your hands, between your fingers, and under your nails for at least 20 seconds. That’s about how long it should take you to sing “Happy Birthday” twice.

Limit your drinking.

It’s true that moderate amounts of alcohol have been tied to some health benefits, like a lower risk of heart disease, but there are also serious downsides to drinking, such as a higher risk of cancer and liver disease. So you shouldn’t start drinking for the sake of good health. When you do have alcohol, keep it to one drink per day if you’re a woman or two if you’re a man.

Steer clear of smoke.

Smoking doesn’t just hurt your lungs. It harms almost every organ in your body, making you a more likely target for cancer, heart disease, and other serious illnesses. Secondhand smoke is dangerous, too, and there’s no amount that’s “safe.” If you live with a smoker, support them in quitting or at least ask them to take it outside.

Map your family tree of health.

A history with a disease doesn’t guarantee your fate, but your genes do offer a clue about the health issues you might face. You may need to be screened more often or earlier for conditions that run in the family, especially when close relatives developed them at unusually young ages or several family members had them. Let your doctor know about any serious ailments your parents, siblings, and children have been diagnosed with.

Check in with your doctor.

While there’s no one-size-fits-all time frame for seeing your primary care doctor (anywhere from annually to every 3 years might be OK), don’t go AWOL. Regular visits can help you catch problems early, when they’re easier to treat and often cure. Stay on top of tests like cholesterol checks, mammograms, and prostate cancer screenings.

Use prescriptions correctly.

Missing doses or taking your medication at the wrong time can have serious consequences. According to the CDC, so-called “non-adherence” leads to 125,000 deaths every year. If you aren’t taking your prescribed medicine because of side effects or other issues, talk to your doctor. Having trouble remembering? Put notes on your calendar or set alarm reminders on your phone or watch.

Stay up to date on vaccines.

Grownups need shots, too. You should get a flu shot every year, but you may also be due for a tetanus booster, a shingles vaccine, or a shot to protect against pneumonia. Ask your doctor what you might be missing and when you should get it.COVID-19 vaccine recommendations will be updated as needed, so it is important to stay up to date on COVID-19 vaccines.

Take baby steps.

It’s tempting to overhaul your entire lifestyle at once. But tackling too many health goals at once often backfires because change can be hard. To better your odds of getting — and staying — healthier, make a series of small changes and work your way up to a bigger end game. For instance, if you’d like to eat a more nutritious diet, focus on breakfast. Once you get used to that, think about how to improve your lunch menu.

Don’t go it alone.

Whatever your health goals are, it will be far easier to reach them if someone has your back. That might mean finding an exercise buddy who meets you at the gym, asking a friend to go with you to doctor’s appointments, or simply confiding in someone you trust about your current struggles so they can cheer you on along the way.

“Sweetness should be consumed in moderation, regardless of the calories,” 

caution researchers, as a new study reveals the impact of consuming artificial sweeteners on metabolism and glucose control.

New research suggests that artificial sweeteners also have metabolic effects.

Lately, we have been hearing a lot in the media about the dangers of sugar consumption. Added sugar raises the risk of obesity, cardiovascular disease, and type 2 diabetes, not to mention having an addictive effect on the brain. 

Therefore, in an attempt to avoid sugar, many people have turned to low calorie sweeteners instead. Artificial sweeteners provide the sweet taste with none of the side effects, so it appears to be a welcome and healthful “trick.” 

So, many people have bought into the idea that, according to some estimates, about a quarter of children in the United States, and more than 40% of adults, are currently consuming low calorie sweeteners.

But, are artificial sweeteners as harmless as people seem to think? Research from a few years ago suggested that artificial sweeteners can still promote diabetes and obesity. And now, a new study adds to the evidence that sweeteners may have undeniable metabolic effects. 

In fact, the latest study suggests that merely tasting something sweet could alter our metabolism and glucose control.

People should consume sweetness in moderation

By contrast, when people with obesity swallowed the sweetener, their insulin levels spiked a lot more compared with when they drank distilled water or when they only tasted the sweetener. 

“While insulin responses to either tasting or swallowing the sucralose were similar in those of normal weight, those responses were very different in people with obesity. “Therefore, we hypothesize that some post-ingestive effects of sucralose may occur only in people with obesity.”

The researcher cautions, however, that different sweeteners have different chemical structures, so the findings of this study, regarding the “post-ingestive effects,” may apply exclusively to sucralose. Nevertheless, the effect of sweet taste alone may be more generalizable.

Intriguingly, and contrary to what the researchers expected, the study also found that merely tasting the sweetener had a metabolic effect, as well.

“Interestingly, we found that in both groups of people — those with obesity and those of normal weight — there was a reduction in insulin response to the glucose tolerance test when they just tasted sweetness before drinking the glucose solution.

The researchers acknowledge the limits of their results, saying, “What our data suggest is that there are mechanisms that we don’t understand clearly about how the human body regulates glucose, and the potential metabolic effects of tasting something sweet beyond providing a sense of pleasure.”

However, they stress the importance of eating sweet foods in moderation.

“Even though the sample population in our study was small, the findings add to a body of evidence that suggests sweetness should be consumed in moderation, regardless of the calories.

Will I get cancer from using artificial sweeteners like sucralose?

The first topic we delved into was that of the link between artificial sweeteners and cancer. This particular piece of research found that a chemical in a commonly used artificial sweetener may cause DNA damage.

The chemical in question was sucralose-6-acetate, a metabolite of the sweetener sucralose. The study findings showed that sucralose harms gut health and may lead to oxidative stress, inflammation, and DNA damage, and hence increase the risk of cancer.

Dr. Hilary Guite, our presenter, pointed out the most common food items that contain this sweetener: “It’s in chewing gum, salad dressings, barbecue sauces, sugar-free jams…”

One important nuance here was that this study was done on human blood cells. To see the same DNA-damaging effect in humans, an average human weighing 70 kilograms would have to consume 18 liters of sucralose-sweetened beverages daily.

What should we do in order to live healthier lives for longer? Research shows there are a few lifestyle interventions that can effectively prolong our life and health span. One of these is exercise, but what kind, and in what combinations, and why does it help add years to our lives? 

Seemingly since times immemorial, humankind has been, metaphorically speaking, seeking the path that leads to the “Fountain of Youth” — that is ways to ensure a longer, healthier life.

And while we may not yet benefit of any “miracle” medicines or technologies to prolong our life spans well over the hundred-year mark, many recent studies have provided strong evidence in support of the notion that simple, achievable lifestyle changes can help us stay healthy for longer and decrease our risk of premature death.

Research presented at the American Heart Association’s Scientific Sessions 2023, for example, suggested that eight healthy habits can slow down biological aging by as much as 6 years.

These habits are related to diet, maintaining a healthy weight, avoiding tobacco, maintaining good sleep hygiene, managing cholesterol, blood sugar, and blood pressure, and, no less importantly, staying physically active.

Dr. del Pozo Cruz is principal researcher in Applied Health Sciences at the University of Cadiz in Spain, and adjunct associate professor in the Department of Sports Science and Clinical Biomechanics at the University of Southern Denmark.

In collaboration with other researchers, Dr. del Pozo Cruz has conducted various studies exploring the link between different forms of exercise and the risk of death from different causes.

Dr. Brocklesby has gained fame under the nickname “Iron Gran,” as at the age of 72, she was the oldest British woman to complete an Ironman Triathlon. She is also founder and CEO of Silverfit, a not-for-profit organization promoting lifelong fitness.

What types of exercise lower death risk?

In a study published in JAMA Internal Medicine in August 2023, Dr. del Pozo Cruz and his colleagues analyzed data from 500,705 participants followed up for a median period of 10 years to see how different forms of exercise related to a person’s mortality risk.

The study looked at the effect of moderate aerobic physical activity, such as walking or gentle cycling, vigorous aerobic physical activity, such as running, and muscle-strengthening activity, like weight lifting.

Its findings indicated that a balanced combination of all of these forms of exercise worked best for reducing mortality risk.

More specifically, around 75 minutes of moderate aerobic exercise, plus more than 150 minutes of vigorous exercise, alongside at least a couple of strength training sessions per week were associated with a lower risk of all-cause mortality.

When it came to reducing the risk of death linked to cardiovascular disease specifically, Dr. del Pozo Cruz and his collaborators suggested combining a minimum of 150–225 minutes of moderate physical activity with around 75 minutes of vigorous exercise, and two or more strength training sessions per week.

Dr. Brocklesby, who goes by “Eddie,” is herself an example of the importance of combining different forms of exercise. Indeed, training and participating in a triathlon — which is an endurance multisport race where participants compete in swimming, cycling, and running — involves achieving a balanced “diet” of moderate and vigorous exercise, as well as strength training.

How little exercise is enough?

But what about people who are not nearly as athletic? What is the minimum “amount” of exercise that could help fend off some of the conditions that pose the highest threat to health?

Dr. del Pozo Cruz and his team may also have found an answer to this question. In December 2022, they published the findings to a previous study in the European Heart Journal.

This research suggested that engaging in vigorous exercise for only 2 minutes a day could help slash the risk of death related to cancer or cardiovascular events.

The researchers found that study participants who never engaged in vigorous exercise had a 4% risk of dying within 5 years, but introducing less than 10 minutes of vigorous activity weekly halved this risk. Moreover, their risk of death halved again for those who engaged in at least 60 minutes of exercise per week.

Is any physical activity good?

In our podcast, Dr. del Pozo Cruz emphasized that almost any amount of any form of exercise is better than none, a point reinforced by a new study arguing that any activity at all is better for heart health than a sedentary lifestyle.

However, he also cautioned that physical activity related to chores or to one’s job, as opposed to exercise in a leisure context, may sometimes do more harm than good.

Once again, his idea is supported by recently published research, which found a link between physically demanding occupations and a higher risk of cognitive impairment.

Some of the most common occupations linked to intensive physical activity cited in this research were in nursing and care, retail, and farming, where individuals are on their feet a lot, and often having to deal with stressful situations.

So while all forms of exercise can be good for health, strenuous or intensive physical activity in a work environment could end up compounding the risk of various health conditions.

And even exercise for leisure can affect aspects of physical health — such as joint integrity — particularly later in life. In our podcast, both Dr. del Pozo Cruz and Eddie emphasized the importance of consulting a trusted healthcare provider, who can advise on the best forms of exercise to engage in on an individual basis.
