Is sugar bad for you? It depends on how you eat it.
Current WHO recommendation to reduce free sugar intake from all sources to below 10% of daily energy intake for supporting overall health is not well supported by available evidence

Surprising Findings
Sugar in solid foods (like cookies or cereal) showed no independent link to weight gain or metabolic disease, even at 20–25% of daily calories.
Most public messaging says ‘sugar = bad’ regardless of source — this flips that by showing form (liquid vs. solid) may be the real differentiator.
Practical Takeaways
Cut back on sugary drinks first — they’re the only form with strong, consistent evidence of harm.

Eating too much fructose, like the sugar in soda and sweet snacks, makes your liver create more fat, which raises bad fats in your blood and causes body-wide inflammation, making heart disease more likely.
Eating way too little sugar might be just as bad for your nutrients as eating way too much sugar—both extremes can make your diet less healthy.
Eating a moderate amount of sugar from foods like fruit or baked goods doesn’t seem to make people gain weight or get metabolic diseases, even if you’re eating other healthy things.
Some studies say drinking sugary sodas is linked to weight gain and health problems, but eating sugar in foods like candy or cake doesn’t seem to have the same effect—so maybe how you consume sugar matters more than how much you eat.
Scientists often give animals way more sugar than people normally eat—sometimes more than half their calories—and use pure fructose, which isn’t how humans usually consume sugar. So, the results from these animal studies might not apply to real human diets.
