A red wine with more than 1,000 calories is now the “biggest single source of energy” to a human being, according to a new study.
The findings by the University of Colorado, Boulder, have been cited in a recent paper that suggests red wine’s energy density has become an issue in the fight against obesity.
The study, which was conducted in the US, compared the energy density of a glass of red wines with a glass containing 1,100 calories.
It found that the energy of red-wine glasses is the “single largest source of total energy” a human would require for their daily activities.
“Red wine has an energetic spectrum that is unique among wine, as its energy density is extremely high,” said study author Dr Daniel E. Smith.
“[This] is a big issue in terms of the global energy challenge because of the increasing consumption of red and white wine.
Red wine is a great source of calories.”
The study also found that red wines contained a “substantial amount of carbohydrate” and “added more than 20% to the energy content of red beer”.
Red wine also contained “higher levels of phosphorous, calcium, iron, zinc, potassium, and magnesium” than white wines, the study found.
As a result, red wines are often the only source of nutrition to a large portion of the world’s population, said Smith.
“The red wine is the dominant source of the calories that are consumed in our society,” he said.
Smith said red wine should not be viewed as a food or beverage but rather a “superfood”.
“It’s an important energy source, a great energy source and a powerful nutritional source,” he added.
“It has been associated with many health benefits, including a reduced risk of cardiovascular disease, diabetes, and cancer.”
