Taking care of your kidneys is important for your overall health. This article explains 5 foods you should stop eating at night to prevent kidney problems.
Do you know that what you eat is important in your kidney function? Particularly at night, according to research by the National Institute of Diabetes and Digestive and Kidney Diseases, your body’s metabolism slows down, making it important to choose soft foods for your kidneys.
Here are 5 foods you should stop eating at night to prevent kidney problems and ensure your kidneys stay happy and healthy:
1. High-Sodium Foods
Sodium, commonly found in table salt and processed foods, can harm your kidneys, especially when consumed in excess.
At night, consuming high-sodium foods can lead to water retention and increased blood pressure, both of which can strain your kidneys over time.

2. Processed Foods
Processed foods are convenient but often contain high levels of additives, preservatives, and unhealthy fats, which can burden your kidneys.
These foods are normally low in nutrients and high in refined sugars and unhealthy fats, contributing to inflammation and oxidative stress in the body.
What to avoid:
- Fast food items like burgers, fries, and pizza
- Packaged snacks like cookies, cakes, and sugary cereals
- Frozen meals with added sauces and flavorings

Choosing whole, unprocessed foods ensures you’re giving your kidneys the nutrients they need without overloading them with harmful additives.

While protein is important for muscle repair and overall health, consuming too much protein, especially at night, can strain your kidneys, according to GJ Ko · 2020.

When your body breaks down protein, it produces waste products like urea that must be filtered out by the kidneys.
Taking excessive protein can lead to increased kidney workload and potential damage over time.
What to avoid:

- High-protein snacks like protein bars and shakes
- Excessive amounts of dairy products

Balancing your protein intake throughout the day and going for plant-based sources can help lighten the load on your kidneys while still meeting your nutritional needs.
4. High-Potassium Foods
Potassium is a mineral that plays an important role in muscle function and heart health.
However, for people with compromised kidney function, consuming high-potassium foods, especially at night, can be problematic.
According to research by LV Simon · 2023, kidneys regulate potassium levels in the body, and excess potassium can lead to hyperkalemia, a condition that can affect heart rhythm and muscle function.

Monitoring your potassium intake, especially if you have kidney issues, can help prevent complications and maintain optimal kidney function.

5. Caffeine and Alcohol
According to research by KCMM Polhuis · 2017, both caffeine and alcohol can have a diuretic effect, meaning they increase urine production.
While moderate consumption of these substances is generally considered safe for most people, excessive intake, especially close to bedtime, can lead to dehydration and strain on the kidneys.
What to avoid:
- Coffee, tea, and energy drinks in large quantities
- Alcoholic beverages, especially sugary cocktails, and heavy beers
What to choose instead:
- Herbal teas or decaffeinated beverages
- Water and natural fruit juices in moderation
- Non-alcoholic mocktails or light beer if you choose to drink alcohol
