Refined sugar is a completely unnecessary food additive, our bodies don' need it, and it causes both short term and long term damage to the body. In the short term, it can cause jitteriness, fatigue, mood swings, acne, sleep problems, and urinary tract infections. In the long term, it can cause cancer, Alzheimer's, diabetes, inflammation, weight gain (obesity), and mood disorders. And worse? it's almost impossible to avoid.
