Question: Which martial artist advocates for consumption of a sugar substitute?
Context: Chocolate milk is sweetened chocolate-flavored milk.  It can be made by mixing chocolate syrup (or chocolate powder) with milk (from cows, goats, soy, rice, etc.).  It can be purchased pre-mixed with milk or made at home by blending milk with cocoa powder and a sweetener (such as sugar or a sugar substitute), melted chocolate, chocolate syrup, or a pre-made powdered chocolate milk mix.  Other ingredients, such as starch, salt, carrageenan, vanilla, or artificial flavoring are sometimes added. A sugar substitute is a food additive that provides a sweet taste like that of sugar while containing significantly less food energy.  Some sugar substitutes are produced by nature, and others produced synthetically.  Those that are not produced by nature are, in general, called artificial sweeteners. Maltitol is a sugar alcohol (a polyol) used as a sugar substitute.  It has 75–90% of the sweetness of sucrose (table sugar) and nearly identical properties, except for browning.  It is used to replace table sugar because it is half as caloric, does not promote tooth decay, and has a somewhat lesser effect on blood glucose.  In chemical terms, maltitol is known as 4-O-α-glucopyranosyl--sorbitol.  It is used in commercial products under trade names such as Lesys, Maltisweet and SweetPearl. Hydrogenated starch hydrolysates (HSHs) are mixtures of several sugar alcohols (a type of sugar substitute).  Hydrogenated starch hydrolysates were developed by a Swedish company in the 1960s.  In the United States, hydrogenated starch hydrolysates are provided by three manufacturers.  The HSH family of polyols is an approved food ingredient in Canada, Japan, and Australia.  HSH sweeteners provide 40 to 90% sweetness relative to table sugar. Stevia ( , or ) is a sweetener and sugar substitute extracted from the leaves of the plant species "Stevia rebaudiana". Norbu, is a brand of sweeter, claiming to be 100% natural.  Norbu is a sugar substitute containing Monk Fruit and Erythritol .  Norbu can be used as a sweetener for teas and coffees but also in baking and cooking as a sugar substitute.  Norbu sweetener was launched into market in 2013 in Coles and Woolworths in Australia. Squash (also known as dilute) is a non-alcoholic concentrated syrup used in beverage making.  It is usually fruit-flavoured, made from fruit juice, water, and sugar or a sugar substitute.  Modern squashes may also contain food colouring and additional flavouring.  Some traditional squashes contain herbal extracts, most notably elderflower and ginger. Dan Quinn is an American professional mixed martial arts fighter currently associated with the Gladiator Challenge promotion, and former amateur and professional boxer, also collegiate American Football player.  Quinn is notable for his advocacy of Stevia as a performance-enhancing substance and fat burner. Isomalt is a sugar substitute, a type of sugar alcohol used primarily for its sugar-like physical properties.  It has little to no impact on blood sugar levels, and does not stimulate the release of insulin.  It also does not promote tooth decay, i.e. is tooth-friendly.  Its energy value is 2 kcal/g, half that of sugars.  However, like most sugar alcohols, it carries a risk of gastric distress, including flatulence and diarrhea, when consumed in large quantities (above about 20-30 g per day).  Isomalt may prove upsetting to the intestinal tract because it is incompletely absorbed in the small intestine, and when polyols pass into the large intestine, they can cause osmotically induced diarrhea and stimulate the gut flora, causing flatulence.  As with other dietary fibers, regular consumption of isomalt can lead to desensitisation, decreasing the risk of intestinal upset.  Isomalt can be blended with high-intensity sweeteners such as sucralose, giving a mixture that has the same sweetness as sugar. Truvia (marketed and stylized as truvía) is a stevia-based sugar substitute developed jointly by The Coca-Cola Company and Cargill.  It is distributed and marketed by Cargill as a tabletop sweetener as well as a food ingredient.  Truvia is made of rebiana, erythritol, and natural flavors.  Because it comes from the stevia plant, Cargill classifies it as a natural sweetener in addition to being a non-nutritive sweetener, although Cargill has settled lawsuits alleging deceptive marketing of Truvia as "natural".  Since its launch in 2008, Truvia natural sweetener has become the second best-selling sugar substitute in units in the U.S. behind Splenda, surpassing Equal and Sweet'n Low.  Truvia competes with Stevia In The Raw, the #2 brand of stevia and with PepsiCo's PureVia, the #3 brand of stevia.
