Is Trump’s favorite “diet cole” healthy? It does not contain real sugar, so you will be more eager for sweets!

Diet Coke's most well-known "spokesperson" today may be US President Trump.

There is even a famous red button in President Trump's White House office. With just one click, the assistant will give him a bottle of his favorite Diet Coke.

Despite its popularity, whether Diet Cole will affect health has been debated among researchers, nutritionists and doctors, mainly the artificial sweetener Aspartame added. Although Diet Coke does not contain real sugar, artificial sweeteners can cause new treatments, increase appetite and lower foot feeling, and even affect kidney health and insulin sensitivity, which may increase risk of obesity and heart disease.

There are many conflicting reports about the risks of Aspartame, including whether it will be detrimental.

According to WebMD, aspartame, like ordinary sugar, will cause the brain to release hormones such as dopamine, making people more eager for sugary foods and drinks.

Lelli said: "Aspartame in Diet Coke stimulates dopamine and increases desire for more sweets, thus defrauding the brain and reducing GLP-1 (hormones that are responsible for foot feeling), making people more likely to overeat."

Some studies also pointed out that there is a potential connection between artificial sweeteners and insulin sensitivity, and Lailli compared it to "trying to open a sticky door with an incorrect key."

She explained: "Under normal circumstances, insulin is the key to open cells, allowing sugar (glucose) to enter the cells and use it as energy, but if insulin resistance occurs, it will leave sugar in the blood, leading to high blood sugar. The body may also produce more insulin, resulting in excessive insulin in the blood and continuous increase in blood sugar, which may cause weight gain, fatigue and unstable appetite."

The artificial sweetener in Diet Cole also changes the microbiome and induces health in the kidneys.

studies show that these sweeteners increase bacteria and reduce beneficial tract bacteria, leading to misalignment of bacteria, which may damage epilepsy, cause inflammation, and cause digestive problems such as gastrointestinal and gastric aches. ”

Studies have also shown that Diet Cole and other products containing artificial sweeteners may increase the risk of dementia.

A related study in 2017 found that people who drink diets every day have three times the chance of developing dementia or mesogenia than those who do not drink it. Another 2019 study tested different effects of sweeteners on mouse behavior and neurologic reproduction, and found similar evidence.

Leilly said that this is because aspartame and sucralose can plague neurologic activities, which in turn affects brain function.

Aspartame may also bring higher cardiac diseases, as elevated blood sugar, insulin resistance, increased abdominal fat and elevated cholesterol levels can cause oxidative pressure, leading to inflammation, stiffness, hypertension and cardiovascular disease

A study published by the National Medical Library of the United States found that people who drink diets every day have a risk of cardiovascular disease 43% higher than those who do not drink, and published in "Cell" in February 2025 A study in the journal Metabolism showed that aspartame-induced insulin surges may lead to the accumulation of fat patches in the angiopia, thereby increasing the chances of heart disease and mediation.

This research report also points out that Diet Cole also contains phosphoric acid and tric acid, which can weaken the quality and permanently invade the teeth. The weakened quality is also easier to dye, affecting the health of the teeth from the inside out.

The only good news is that aspartame's carcinogenicity certificate for humans is "limited" based on the International Agency for Research on Cancer, the World Health Organization (WHO), the FAO, and the Joint Expert Committee on Food Additives.

WHO reported that as long as you do not drink too much, the FDA still believes that Diet is safe.

However, nutritionists warn that the boundary of "but excessive" is difficult to define, so the less you drink, the better.
