## Resource

Long-term, low-dose aspartame intake caused measurable changes in heart structure and brain energy use in mice, even at amounts far below current safety limits Weight and body fat dropped with aspartame use, but this came alongside reduced metabolic function and signs of cardiac strain rather than improved health Brain cells showed worsening access to fuel over time, which aligned with slower movement, poorer memory, and reduced task performance Harmful effects developed gradually and only appeared after many months, explaining why short-term studies often miss these risks Avoiding artificial sweeteners and restoring real carbohydrate fuel helps reduce metabolic stress and protect long-term heart and brain function
