Molasses is a syrup made from the extraction of sugar from sugarcane and sugar beets, and the nutritional value of molasses varies greatly depending on how much sugar is extracted, states About.com. However, all types of molasses contain sugar, and sugar has powerful effects on the human body.
Sugar affects the body by triggering insulin secretion, says Women's Health. Insulin is a hormone that pulls sugar from your blood to be used as energy. The brain balances insulin with serotonin, which causes the sugar crash, and insulin blocks the hormone for hunger, so the body feels hungry even after eating a lot. Sugar that isn't used by other cells stays floating in the blood stream and may lead to diabetes. Consuming too much sugar lowers HDL, the good cholesterol, and promotes the production of triglycerides.
Molasses also contains a concentrated level of vitamins and minerals, such as iron, calcium, magnesium and potassium. The amount of these nutrients is different depending on brand and variety, says About.com, so be sure to check the nutrition label. Black strap molasses is the type of molasses with the least amount of sugar and the highest concentration of nutrients. Light molasses has the highest sugar content and least amount of nutrients.
