Our Eating Habits Affecting Kidneys

Our eating habits are directly affecting our kidneys. We have not to concern with selection for food items, we always eat too many foods high in sugar. Sugar contributes to obesity, which increases your risk of developing high blood pressure and diabetes, two of the leading causes of kidney disease.

Foods that cause kidney damage

1. Avocados:

Avocados are a versatile fruit that is packed with nutrients. These are a great way to add healthy fat to your diet. Avocados also come with a high dose of potassium, which controls fluids, electrolyte balance, and pH level.

2. Dairy Products:

Milk, Butter, Yogurt, Cheese, and Milk contains a high quantity of calcium. More use of dairy products increases the level of calcium in your urine. Which causes a higher risk of kidney stones.

3. Artificial Sweeteners:

If you are adding an artificial sweetener to your food, to make them taste sweet. All these efforts to reduce your sugar consumption, you aren’t actually doing your body any favors. The artificial sweetener or sugar substitute is a chemical. Usually, it has a much lower energy value than sugar.

4. Nuts:

Use of Nuts is not good, in case you at risk of kidney stones or if you’ve had stones in the past, skip the nuts altogether. Nuts are very healthy additions to your diet however as with many things, balance is fundamental. Select the variety of greens vegetables rather than nuts.

5. Salt:

Salt, also known as sodium chloride (NaCl). It is about 40% sodium and 60% chloride and the Na (sodium) works in combination with P (potassium) to maintain the fluid balance in your body. Which is crucial to the proper functioning of the kidneys.

Eating Salts:

Eating salt raises the amount of sodium in your bloodstream and wrecks the delicate balance, reducing the ability of your kidneys to remove the water. The result is a higher blood pressure due to the extra fluid and extra strain on the delicate blood vessels leading to the kidneys.

6. Caffeine:

Some studies show that long-term consumption of caffeine can worsen chronic kidney disease. It also increases the risk of kidney stones. Caffeine causes a short but sudden increase in blood pressure. Moderating how much coffee you drink is a good idea.

7. Meat:

The highest amounts of red meat had a 40 percent increased risk of developing end-stage kidney disease, compared with people who ate the lowest amounts. Meat contains a significant amount of protein. Protein is very important to growth processes and the health of our muscles, but metabolizing it is one of the hardest jobs our kidneys do.
