It has been associated with better digestive health, lower levels of blood sugar and cholesterol, as well as increased feelings of fullness. Guar gum is a long-chain carbohydrate used to thicken and bind foods. It is common to use cement additives that increase the mechanical strength by chemical activation, without changing the cement surface and particle size distribution. Extended cement slurries are used to reduce the hydrostatic pressure on weak formations and to decrease the cost of slurries. Many other studies have found a similar association, reporting that a higher intake of processed meats may be linked to a higher risk of colorectal, breast and bladder cancer (15, 16, 17).
