These add up quietly and affect energy, sleep and heart health more than most people realize. Your daily limits below follow general guidance -- added sugar under ~50g/day (WHO), caffeine under ~400mg/day for most healthy adults, and alcohol tracked in ml of pure alcohol rather than "drinks" (e.g. a 500ml beer at 5% ABV = 500×0.05 = 25ml pure alcohol), kept to low-risk levels of ~50ml/day for men and ~25ml/day for women, with alcohol-free days each week. These limits are fixed to general population guidelines and can't be edited, since they aren't personal preferences. These are general guidelines, not medical advice -- adjust with your doctor if you're pregnant, sensitive to caffeine, or managing a health condition.
