Is Sugar 'Poison'? Doctor Explains Dangers

Dr. Robert Lustig, a leading pediatrician and endocrinologist, asserts that added sugars are detrimental, likening them to poison. He identifies four key reasons for this: the harmful effects of fructose on liver function, leading to conditions like fatty liver disease; glycation, a process that accelerates aging and contributes to numerous chronic diseases; interference with the gut microbiome and immune system; and sugar's addictive properties stemming from fructose's impact on the brain's reward system.

Lustig's research indicates that consuming excessive added sugar can shorten life expectancy by approximately 15 years. Fortunately, he emphasizes that substantial health improvements and recouping lost years are possible by adhering to recommended daily sugar limits, especially from unprocessed foods. He advocates for eliminating sugary drinks, opting for whole fruits, and prioritizing ‘real food’ – unprocessed items – to minimize sugar consumption.
