 ANSWER: A

• According to recent research, Erythritol, a popular artificial sweetener, is associated with an increased risk of heart attack and stroke.
• Erythritol activates platelets, the blood cells which cause clots when they clump together. Such aggregation of platelets blocks blood flow in blood vessels in different parts of the body.
  • When that happens in blood vessels supplying blood to the heart or brain, fatal or non-fatal cardiovascular events occur.

About Erythritol

• It is a type of sugar alcohol commonly used as a sugar substitute in foods and beverages.
  • Unlike traditional sugars, it has no calories and does not raise blood sugar levels.
• Artificial sweeteners are common replacements for table sugar in low-calorie, low-carbohydrate and “keto” products (high in fat and low in carbohydrates).
• Low Glycemic Index (GI): It is also believed to have a lower GI than other sweeteners, meaning it may not impact insulin levels as strongly.
  • GI is a value used to measure how much specific foods increase blood sugar levels.
• Uses: Sugar-free products containing Erythritol recommended for people who have obesity, diabetes or metabolic syndrome. People with these conditions also are at higher risk for adverse cardiovascular events like heart attack and stroke.

ANSWER: B

• Scientists at Paderborn University, Germany have been able to make a unique class of catalysts called Lewis super-acids.
• Named after chemist, G N Lewis, Lewis super-acids derive from Lewis acids.
• A Lewis acid is any substance, such as a Hydrogen ion (H+) that can accept a pair of nonbonding electrons. In other words, it is an electron-pair acceptor.
• They are often used to speed up chemical reactions.
• Lewis superacids are stronger than antimony pentafluoride– strongest Lewis acid — and can break even toughest bonds.
• A Lewis base is any substance, such as OH- ion, that can donate a pair of nonbonding electrons. Therefore, it is an electron-pair donor.
