This fall drink will paralyze your blood vessels. We're talking mulled wine - a warming wine-based cocktail with citrus fruits and spices. The rapid absorption of sugar and alcohol from a hot drink causes a spike in glucose and a sharp spasm of blood vessels, nutritionist Elena Solomatina told the section. "Hot wine is strictly prohibited for pregnant women, breastfeeding women, people with mental illnesses, insulin resistance, ulcers in the digestive system, liver and heart diseases," she warned. Another dangerous mistake is the healing properties of hot wine. Alcohol during illness only causes additional stress on the body and causes complications.
