28 Oct 2022 --- Following a recent report by the Australian government revealing that two-thirds of the country’s adults and a fourth of its children are considered to be obese or overweight, researchers in the country have discovered that engineered particles of porous sand silica may help to treat obesity with better results than the leading pharmaceutical intervention. The sand silica treatment adsorbs digestive enzymes, sugars, fats and carbohydrates and may allow them to pass through the body without being absorbed with less adverse gastrointestinal (GI) effects.
