Sugar is the only substance that humans ingest that has no nutritional value whatsoever, no essential fats, no protein, no vitamins, no minerals… in terms of sugar, we either eat in on top of what we should be eating, in which case it can make us fat, or we eat it instead of what we should be eating, which leaves us nutritionally deficient and we end up sick. So we’re getting fat and sick at the same time. ‒ Dr Zoe Harcombe, PhD, Public Health Nutrition Researcher
Actually, there is one other substance that meets these criteria: alcohol. Alcohol is not a nutrient either, and alcohol and sugar bear striking similarities in the ways in which they work on your liver and your brain.
But Dr Harcombe is absolutely correct, of course. Contrary to what the food industry may wish you to believe, the human body has no biological requirement for added sugar whatsoever, and sugar is therefore not a ‘nutrient’ and should be described only as an ingredient or additive. When we refer to ‘added sugar’, we are discussing sucrose (50 per cent glucose and 50 per cent fructose) or high-fructose corn syrup (45 per cent glucose and 55 per cent fructose).
