Are Walnuts Acidic or Alkaline? (Expert Answer)

Short Answer: Walnuts are acidic with a pH level of 5.4 and alkaline-forming with a PRAL of -2.8.

Walnuts are a type of nut that grows in temperate regions of the world, such as North America, Europe, and Asia.

They have a hard brown shell and a wrinkled white kernel that is rich in oil and protein.

They are often used in baking, salads, snacks, and sauces.

The acidity or alkalinity of a food is measured by its pH level, which ranges from 0 to 14.

A pH of 7 is neutral, while a pH below 7 is acidic and a pH above 7 is alkaline.

The pH level of a food can affect its taste, shelf life, and health benefits.

Walnuts have a pH level of 5.4, which means they are acidic.

This is because they contain organic acids, such as malic acid and ellagic acid, that lower the pH level.

Another way to measure the acidity or alkalinity of a food is by its potential renal acid load (PRAL), which is the amount of acid or base that the food produces in your body after being digested.

Foods with a high PRAL create more acid in your body, while foods with a low or negative PRAL create more base in your body.

The PRAL of a food is calculated by measuring the amount of protein, phosphorus, potassium, magnesium, and calcium that it contains.

Protein and phosphorus are acid-forming, while potassium, magnesium, and calcium are base-forming.

Walnuts have a PRAL of -2.8, which means they are alkaline-forming.

This is because they contain high amounts of potassium, magnesium, and calcium that outweigh the acid-forming effects of protein and phosphorus.

Eating acidic and alkaline-forming foods can have positive effects on your health.

They can help digestion, kill harmful bacteria, provide vitamin C, and balance the pH of your blood, which is slightly alkaline.

They can also prevent acidosis, a condition that occurs when your body becomes too acidic.

You can eat walnuts raw, cooked, dried, or preserved.

You can also make walnut oil, butter, milk, or flour.

However, you should be careful of potential hazards, such as allergies, mold, or rancidity.

You can store walnuts in a cool, dry, and airtight place for up to a year.

Do not store walnuts in a warm, moist, or open place or with other foods that may affect their quality, such as onions, garlic, or bananas.

Finally, remember, walnuts are a nutritious and versatile food that can benefit your health in many ways.

They are a good source of omega-3 fatty acids, antioxidants, fiber, and minerals.

They can also improve your brain, heart, and skin health.
