Avocados are incredibly nutritious. They are an excellent source of healthful fats and are packed with vitamins, minerals, and phytochemicals. Sadly, they might not be the best for the kidneys. Avocados are extremely high in potassium, which the kidneys may find challenging to absorb. It's acceptable to occasionally decline guacamole because people with kidney issues will probably be advised by their doctors to avoid consuming too much potassium. Restrictive renal diets often have low levels of sodium, potassium, protein, and phosphorus, all of which are challenging for the kidneys to digest. Diets rich in these ingredients can cause renal disease later in life, even in those with healthy kidneys.
