About this food
Sugar (Snacks & Sweets). Snacks and sweets are mostly processed foods that often contain inorganic phosphorus additives (the most absorbable kind) and added sugar, making them a high-caution category in CKD. This is the same lens used for similar items.
Nutrient insight
Potassium is the highest of the three at 1%. With reduced kidney function, blood potassium can rise, so spread high-potassium foods across the day rather than in one large serving.

How much Potassium is in Sugar?
In every 100 g of Sugar, Potassium is about 29 mg - roughly 1% of the daily limit (2,000 mg).
Is Sugar safe on a low-potassium diet?
For people watching potassium, Sugar falls below 300 mg per 100 g, with Potassium at 29 mg. Confirm your personal limit with your nephrologist or renal dietitian.
How does Sugar compare to other snacks & sweets foods?
Against the Snacks & Sweets average, Sugar shows less Potassium (29 mg per 100 g). The tier shown here comes from its own numbers, not the category.
