For years, liver disease was closely associated with alcohol.
But there is another liver problem that has become increasingly important: metabolic dysfunction-associated steatotic liver disease, or MASLD.
The condition occurs when excess fat accumulates in the liver in association with metabolic risk factors. Its earlier name, non-alcoholic fatty liver disease or NAFLD, is still widely used, but the newer terminology better reflects what researchers now understand about the disease.
And one everyday habit is attracting particular attention: drinking sugar-sweetened beverages.
A systematic review and dose-response meta-analysis involving 12 studies and more than 35,000 participants found that higher consumption of sugar-sweetened beverages was associated with a greater likelihood of NAFLD. The researchers reported a 1.39-fold higher odds among consumers overall, with stronger associations at higher levels of consumption.
That does not mean a can of soda directly causes liver disease in every person who drinks it.
It does mean that regularly consuming large amounts of added sugar in liquid form can be one piece of a much bigger metabolic picture.
Why the liver gets involved
The liver plays a central role in processing nutrients, regulating blood sugar and handling fats.
When we consume carbohydrates, glucose and fructose are handled somewhat differently. Fructose is largely processed by the liver, and high intakes of added sugars can contribute to increased energy intake and metabolic changes that may promote liver fat accumulation.
But the popular explanation that fructose simply travels straight to the liver and is automatically converted into fat is too simplistic.
The amount of sugar consumed, overall calorie intake, insulin sensitivity, body-fat distribution, physical activity, genetics and other dietary factors all influence an individual’s risk.
That matters because MASLD is not caused by one food or one drink alone.
The silent problem under your ribs
One reason MASLD deserves more attention is that it can be remarkably quiet.
Many people have few or no symptoms even when fat has accumulated in the liver. Some experience fatigue or discomfort in the upper-right abdomen, but symptoms are not reliable for identifying the disease.
That can be particularly important as we get older.
A person may feel perfectly well while living with high blood pressure, type 2 diabetes, abnormal cholesterol levels or insulin resistance—all conditions associated with increased risk of metabolic liver disease.
The liver can therefore become another place where the effects of metabolic health quietly accumulate.
When liver fat becomes liver damage
Not everyone with liver fat develops serious disease.
Some people have relatively little inflammation or injury. Others develop MASH, or metabolic dysfunction-associated steatohepatitis, in which fat accumulation is accompanied by inflammation and liver damage.
Persistent injury can eventually lead to fibrosis, meaning scar tissue develops in the liver. Advanced fibrosis can progress to cirrhosis and, in some people, liver cancer.
The important point is that this progression is not inevitable.
Identifying metabolic risk and addressing it earlier can make a major difference.
You don’t have to be visibly overweight
Perhaps one of the most important messages for older readers is that body size alone does not tell the whole story.
MASLD is more common among people with overweight or obesity, but it can also occur in people who do not appear overweight. Diabetes, insulin resistance, abnormal blood fats, genetics and other metabolic factors can contribute to risk.
That means the question should not simply be:
“Do I look overweight?”
A better set of questions is:
How are my blood sugar, blood pressure, cholesterol, triglycerides and overall metabolic health?
This is especially relevant with aging, when the risk of metabolic conditions can increase.
What about fruit?
This is where sensational nutrition advice can become misleading.
Whole fruit contains naturally occurring sugars, but it also provides fiber, water, vitamins, minerals and other beneficial compounds. Current dietary guidance does not suggest eliminating whole fruit because it contains fructose.
Sugar-sweetened beverages are different because they can deliver substantial amounts of added sugar without the same food structure.
That distinction is more useful than declaring all fructose “bad.”
For people concerned about liver health, the bigger goal is an overall eating pattern rich in vegetables, fruits, whole grains, legumes, nuts and other minimally processed foods, while limiting energy-dense foods and commercially produced high-fructose foods and drinks.
What about your morning coffee?
Coffee has an interesting relationship with liver health.
Research has associated coffee consumption with a lower risk of advanced liver disease in some populations, and current liver-health guidance discusses coffee as part of the broader picture.
But that should not turn coffee into a “liver detox.”
Nor does it mean everyone needs to drink several cups a day.
Individual tolerance, medications, sleep, heart conditions and other health considerations matter. If you already drink coffee comfortably, there is no need to treat it as a miracle medicine—or to add sugar and syrups in the belief that the coffee itself cancels them out.
The most useful change may be hiding in your glass
For someone who drinks sugary beverages every day, reducing them can be a practical place to start.
That might mean choosing water more often, selecting an unsweetened drink or simply making sweetened beverages an occasional rather than routine part of the day.
The goal isn’t dietary perfection.
For older adults especially, nutrition should provide enough protein, fiber and essential nutrients while fitting comfortably around existing health conditions, medications, appetite and lifestyle.
If you have diabetes, high triglycerides, obesity, unexplained abnormal liver tests or other metabolic risk factors, it is worth discussing liver health with your healthcare professional.
Don’t wait for your liver to complain
Because MASLD can have few symptoms, waiting for pain is not a reliable strategy.
Doctors may use medical history, physical examination, blood tests and imaging to investigate suspected fatty liver disease. Depending on the person’s risk, additional tests can help assess whether significant fibrosis is present.
An abnormal liver enzyme result does not automatically mean someone has MASLD, and normal enzymes do not necessarily rule it out.
That is why evaluation needs to consider the whole picture.
A quieter way to protect your liver
The liver does not need a fashionable detox drink.
It needs the same things that support much of the rest of the body: sensible nutrition, appropriate physical activity, management of blood sugar and cholesterol, healthy sleep and medical attention when risk factors appear.
For someone who has been drinking a sugary beverage every day for years, the important question isn’t whether one drink has already “damaged” the liver.
It is what happens when that habit is repeated thousands of times.
A daily soda may look insignificant in the moment.
But health is rarely determined by one moment.
It is shaped by patterns.
And when it comes to your liver, changing one everyday pattern may be far more meaningful than waiting until the organ finally gives you a warning.
