Some people say sugar makes you fat and sick, but this review says: if you eat sugar like most people do — not huge amounts, and instead of other carbs — it doesn’t cause extra harm.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Chronic consumption of ultra-processed foods, refined carbohydrates, and added sugars drives systemic inflammation, insulin resistance, and dyslipidemia, prompting maladaptive dietary counter-reactions.
Eating normal amounts of sugar doesn’t make your blood pressure go up, raise uric acid (which can cause gout), or cause fat to build up in your liver — unlike what some people claim.
When you eat the same number of calories from sugar or from bread or rice, you don’t gain more weight from the sugar — so sugar isn’t uniquely fattening.
Eating normal amounts of table sugar or corn syrup in your food and drinks doesn’t make you more likely to get overweight, diabetes, or heart disease than eating the same number of calories from other carbs like bread or pasta.
Lab studies that give people pure fructose or pure glucose don’t reflect what people actually eat — we usually consume sugar as table sugar or corn syrup, which are mixtures, so those lab results don’t apply to real life.
