Dark-Colored Soda
Sodas, especially those of a darker hue, not only supply unneeded calories and sugars but also contain additives rich in phosphorus. These additives are often incorporated during manufacturing to enhance flavor, extend shelf life, and maintain color. Unlike natural sources of phosphorus, these additives are readily absorbed by the gut due to their salt form. Despite the variance in phosphorus content among different soda types, a 12-ounce cola can contain up to 33.5 mg of phosphorus. Given the high absorbability of additive phosphorus and its prevalence in dark sodas, those with kidney issues are advised to avoid these beverages. [2]
Research indicates that the phosphorus from additives is more bioavailable, meaning the body absorbs it more efficiently than natural phosphorus. This can exacerbate the accumulation of phosphorus in individuals with kidney disease, leading to further complications. Since manufacturers are not obliged to disclose the amount of phosphorus added, consumers must be vigilant and consider the potential risks associated with these beverages.
Whole Wheat Bread
While whole wheat bread is generally recommended over white bread due to its higher fiber content and nutritional benefits, it’s a different story for those with kidney disease. Whole wheat bread contains higher levels of phosphorus and potassium, making white bread a preferable choice for those managing kidney health.
One slice of whole wheat bread contains significantly more phosphorus and potassium than white bread, highlighting the need for careful selection and moderation. Although whole wheat bread may be incorporated into a renal diet in limited amounts, it’s essential to balance its consumption with other dietary needs to avoid excessive intake of phosphorus and potassium.
