Researchers from King's College London published a study suggesting a link between theobromine, a compound in dark chocolate, and slower biological aging. This finding is based on an analysis of nearly 1,700 adults from the UK and Germany. Participants with higher levels of theobromine exhibited more favorable biological aging characteristics, indicating they may appear younger than they actually are. The research, published in the journal Aging, compared theobromine levels in participants with markers of aging, such as telomere length and DNA tests. It's not an invitation to eat more sweets. While the findings are intriguing, researchers caution that increasing dark chocolate intake is not a universal solution for combating aging, given its sugar and fat content. Dark chocolate, also known as bittersweet or pure chocolate, differs from other types of chocolate due to its high cocoa content (generally 50% or more) and the absence or minimal presence of dairy, which gives it its dark color and intense, sometimes bitter, flavor. Its antioxidants make it beneficial. (flavanols).

Despite showing an association, the researchers stress the need for further studies due to the observational nature of this research.

Theobromine Content

Theobromine levels can vary significantly in chocolate, depending on the cocoa content. A typical 40-gram chocolate bar can contain between 200 and 400 milligrams of theobromine.

Scientists plan to conduct follow-up studies to better understand the effects of theobromine and other beneficial compounds present in dark chocolate. This could expand our knowledge of aging and associated diseases.

“While we are not saying that people should eat more dark chocolate,“This research can help us understand how everyday foods may hold clues to a healthier and longer life,” explained Jordana Bell, lead author of the study and professor of epigenomics at King’s College London, in a statement.

On the other hand, “if people like it, they should enjoy it infrequently and in small amounts,” advised Dimitrios Koutoukidis, associate professor of diet, obesity, and behavioral sciences at the University of Oxford, who was not involved in the study.

Dark chocolate has previously been associated with other potential health benefits, Koutoukidis told Fox News. For example, cocoa flavanols can help reduce inflammation, promote heart and vascular health, improve blood flow, stabilize blood sugar, and improve memory.

Adverse effects of excessive theobromine consumption

Excessive consumption of theobromine, an alkaloid found in cocoa and chocolate, can cause Several adverse effects in humans, especially at high doses above 1,000 mg, although it is much less toxic to us than to animals like dogs.

Cardiovascular effects. It increases heart rate and can cause palpitations or tachycardia, particularly in sensitive individuals.

Neurological effects. It causes insomnia, restlessness, nervousness, and in severe cases, migraines or seizures.

Gastrointestinal effects. It causes mild stomach discomfort, such as bloating, gas, or nausea.
