Avocado is a nutritious food, containing a lot of monounsaturated fats, fiber and micronutrients such as potassium, magnesium. However, for people with kidney failure, especially chronic kidney failure, consuming avocados in the evening before going to bed can cause negative effects.
One of the main reasons is the very high potassium content in avocados. 100g of avocado contains about 485mg of potassium higher than the potassium content in bananas.
In people with kidney failure, the kidneys cannot fully filter potassium out of the blood, leading to increased blood potassium. This condition can cause heart rhythm disturbances, even sudden death while sleeping when the body is at a state of complete rest, the heart works more slowly. Experts warn that hyperkalemia is one of the serious complications of kidney failure. Therefore, kidney patients need to strictly control their potassium intake, especially in the evening.
Avocado also contains a lot of fat, which causes the digestive system to work harder to metabolize, causing bloating and indigestion - which is not good for sleep and can affect the circadian rhythm, which is already easily disrupted in kidney patients. According to research, a diet high in potassium and fat in the evening can increase pressure on the circulatory system as well as the kidneys at night, especially in people with reduced renal plaque filtering function.
Although it is a healthy fruit, avocados can become a potential risk for people with kidney failure, especially if eaten before bed. People with kidney disease should consult a nutritionist for a suitable diet to avoid dangerous complications due to potassium blood disorder.
