Boost drinks are available in milk chocolate, vanilla and strawberry flavors, and contain a mix of water, corn maltodextrin, sugar, canola oil and sodium caseinate. Their ingredients also include milk protein concentrate, corn oil, soy protein isolate, cocoa powder, short-chain fructooligosaccharides and calcium beta-hydroxy-beta-methylbutyrate.
Boost's official website claims this drink is meant to supplement a meal and keep the consumer feeling full. Boost is low-fat, does not contain caffeine and provides protein and carbohydrates for energy. Boost also contains 26 vitamins and minerals along with a number of antioxidants.
One of the main ingredients in Boost Nutritional Drink is 25 grams of sugar per serving, which is just five grams fewer than a full-sized Snickers bar, based on nutritional information at The Daily Plate. Sugar can provide energy, but is a simple carbohydrate and leads to an energy crash after a short time. Sugar is also linked to tooth decay.
Milk protein concentrate contains lactose and is to be avoided by people who are lactose intolerant. Milk protein can help build lean muscle and manage weight. According to the May 2008 issue of the American Journal of Clinical Nutrition, protein helps people feel full for longer periods of time. The research also noted that protein increases calorie burning, which leads to fat loss.
