The second category includes soft drinks, sweetened iced tea, packaged fruit drinks, energy beverages containing large amounts of sugar, and other drinks with added sweeteners.
These beverages are often consumed without much thought.
Someone may drink a bottle during lunch, purchase another in the afternoon, and have a sweetened beverage with dinner.
Over time, the calories and added sugar can accumulate.
Although an occasional sweetened drink does not automatically cause a stroke, regularly consuming large amounts can contribute to several established cardiovascular risk factors.
Excess sugar can contribute to weight gain
Most sugar-sweetened beverages contain substantial calories but provide relatively little satiety compared with solid foods.
This means people may consume additional calories without feeling particularly full.
When calorie intake regularly exceeds energy expenditure, body weight can increase.
Excess body weight is associated with a higher risk of hypertension, type 2 diabetes, and other metabolic conditions.
These conditions can significantly increase the likelihood of stroke.
The relationship with type 2 diabetes
Regular consumption of sugar-sweetened beverages is associated with an increased risk of developing type 2 diabetes.
Diabetes affects the way the body processes glucose and can damage blood vessels over time.
Elevated blood sugar may contribute to inflammation, oxidative stress, and changes in the structure and function of arteries.
People with diabetes have a higher risk of cardiovascular disease, including stroke.
Managing blood glucose is therefore an important part of protecting long-term brain and heart health.
Sugar and triglycerides
Excessive consumption of added sugars, particularly in beverages, can contribute to elevated triglyceride levels in some individuals.
Triglycerides are a type of fat circulating in the bloodstream.
High triglyceride levels, especially when combined with other metabolic abnormalities, can contribute to an unfavorable cardiovascular risk profile.
Healthier alternatives
Water is generally the simplest replacement.
Unsweetened tea, sparkling water without added sugar, and plain coffee in moderate amounts can also be suitable options for many adults.
Whole fruit is generally preferable to fruit drinks because it provides fiber and requires more chewing, helping people feel satisfied.
When purchasing packaged beverages, check the nutrition label.
Look beyond the large claims printed on the front of the bottle and examine the amount of added sugar per serving.
A bottle may contain more than one serving, meaning the actual amount consumed could be considerably higher than expected.
4. Drink Number Three: Highly Caffeinated Energy Drinks
Energy drinks have become increasingly popular among people who work long hours, study late, drive long distances, or participate in physically demanding activities.
They are often marketed as products that improve alertness, concentration, and physical performance.
However, highly caffeinated energy drinks deserve caution, particularly among people with existing cardiovascular conditions.
Their caffeine content can vary considerably.
Some products also contain additional stimulants or combinations of ingredients intended to increase alertness.
How caffeine affects blood pressure
Caffeine stimulates the central nervous system.
In some individuals, it can temporarily increase blood pressure.
The effect varies according to habitual caffeine intake, individual sensitivity, medication use, and underlying health conditions.
For healthy adults who regularly consume moderate amounts of caffeine, the body may develop some tolerance to these effects.
However, people with uncontrolled hypertension or certain heart conditions should be more cautious.
Energy drinks may affect heart rhythm
Some research has identified changes in heart rate, blood pressure, and electrical activity of the heart after consumption of energy drinks.
These findings are particularly relevant when large quantities are consumed over a short period.
The combination of high caffeine levels and other stimulant ingredients may be concerning for susceptible individuals.
Although evidence directly linking ordinary energy drink consumption to stroke remains limited, cardiovascular effects provide a reason for caution.
People with atrial fibrillation, uncontrolled hypertension, or other heart rhythm disorders should discuss their caffeine intake with a healthcare professional.
Mixing energy drinks with alcohol
Another concern is combining energy drinks with alcoholic beverages.
Caffeine can make a person feel more alert without reversing alcohol-related impairment.
As a result, someone may underestimate how intoxicated they are and continue drinking.
This can increase the likelihood of excessive alcohol consumption, dehydration, accidents, and other health problems.
How much caffeine is too much?
For most healthy adults, the U.S. Food and Drug Administration identifies 400 milligrams of caffeine per day as an amount not generally associated with dangerous effects.
However, this is not a universal target or a guarantee of safety.
Pregnant individuals, people taking certain medications, and those with cardiovascular conditions may need lower amounts.
Energy drinks should never be treated as harmless substitutes for sleep.
Persistent fatigue is better addressed by identifying its underlying cause rather than repeatedly using stimulants to overcome it.
5. Drink Number Four: High-Sodium Packaged and Processed Drinks
The fourth category is less obvious but important for people who regularly consume packaged beverages.
Certain vegetable juices, instant soups served as drinks, concentrated broths, and savory packaged beverages can contain substantial amounts of sodium.
Some people do not consider these products salty because they are consumed as liquids rather than traditional foods.
However, sodium intake still matters regardless of whether it comes from a solid meal or a beverage.
Why sodium matters for blood pressure
Sodium helps regulate fluid balance and supports normal nerve and muscle function.
However, consuming too much sodium can increase blood pressure in susceptible individuals.
When sodium intake is excessive, the body may retain additional water.
This can increase the volume of fluid circulating through the bloodstream and contribute to higher blood pressure.
Long-term hypertension places continuous stress on blood vessel walls.
Over time, this can increase the risk of stroke, heart disease, kidney disease, and other complications.
Hidden sodium in packaged beverages
Some packaged tomato juices, vegetable drinks, savory nutritional beverages, and concentrated broths contain more sodium than consumers realize.
A product marketed as a healthy vegetable drink is not necessarily low in sodium.
People with hypertension should read the nutrition information carefully.
It is also important to distinguish between naturally occurring sodium and added salt.
Products with reduced sodium may be useful alternatives, although their suitability depends on the individual's overall dietary needs.
