Living your best life at 35, ignoring cholesterol and glucose levels, may impact your chances of getting Alzheimer's disease (AD) later in life. According to new research, lower HDL (high-density cholesterol) and high triglyceride levels measured in blood as early as age 35 are associated with a higher incidence of AD several decades later in life. Researchers also found that high blood glucose measured between ages 51-60 is associated with risk of AD in the future.
