About the Health Information

Rich in healthy fats, fibre, and protein, almonds offer several important nutrients that support overall health. However, they also contain oxalates, which may contribute to certain types of kidney stones in some individuals.

Key points to remember:

• Almonds contain moderate to high levels of oxalates.
• Oxalates can contribute to calcium oxalate kidney stones.
• Not everyone who eats almonds develops kidney stones.
• For individuals at risk of recurrent kidney stones, limiting foods rich in oxalates may be beneficial.
• Portion size and overall diet play an important role.

If you have a history of kidney stones or chronic kidney disease, consult your doctor or dietitian before making significant dietary changes.

Almonds are often considered a healthy snack because they provide protein, healthy fats, fibre, vitamin E, and magnesium.

However, many people with kidney stones wonder whether almonds are safe to eat.

The answer depends on the type of kidney stone you have, your overall diet, and your individual health condition.

For some people, excessive consumption of almonds may increase the risk of developing certain kidney stones.

Almonds do not directly cause kidney stones in everyone.

However, almonds contain oxalates, naturally occurring compounds found in many plant-based foods.

High levels of oxalates can bind with calcium in the urine and contribute to the formation of calcium oxalate stones, the most common type of kidney stone.

If you have a history of calcium oxalate stones, your healthcare provider may recommend limiting high-oxalate foods, including almonds.

Oxalates are naturally occurring substances found in foods such as:

• Almonds
• Spinach
• Beets
• Sweet potatoes
• Chocolate
• Tea

In most people, oxalates are eliminated through urine without causing problems.

Excess oxalates can bind with calcium in the urine, increasing the likelihood of crystal formation that may lead to kidney stones.

Yes. Almonds are considered a high-oxalate food.

The oxalate content can vary depending on serving size and preparation methods.

Eating small amounts occasionally is unlikely to cause kidney stones in healthy individuals. However, consuming large quantities of almonds regularly may increase the risk in people who are prone to calcium oxalate stones.

For most healthy individuals, almonds are not harmful to the kidneys.

They provide several nutritional benefits, including:

• Healthy unsaturated fats
• Plant-based protein
• Fibre
• Vitamin E
• Magnesium

However, people with certain kidney conditions may need to monitor their intake.

This includes individuals with:

• A history of recurrent kidney stones
• Chronic kidney disease
• Elevated potassium levels
• Dietary restrictions recommended by their healthcare provider

If you have previously had calcium oxalate stones, you may not need to avoid almonds completely.

Instead, your healthcare provider may recommend:

• Limiting portion sizes
• Drinking plenty of water
• Consuming calcium-rich foods with meals
• Following a personalised low-oxalate diet

Dietary recommendations vary depending on the type of kidney stone you have.

Almond milk may also contain oxalates, although levels vary by brand and preparation method.

Unsweetened almond milk consumed in moderation is generally safe for most people.

If you have recurrent calcium oxalate stones, check nutrition labels and discuss suitable alternatives with your healthcare provider.

Walnuts also contain oxalates, although their oxalate content differs from almonds.

Neither almonds nor walnuts need to be completely avoided unless your healthcare provider specifically recommends dietary restrictions.

A balanced diet, adequate hydration, and portion control are more important than eliminating individual foods.

You can lower your risk of kidney stones by:

• Drinking enough water throughout the day
• Limiting excessive intake of high-oxalate foods
• Including adequate calcium in your diet
• Reducing excess salt intake
• Limiting processed foods
• Maintaining a healthy body weight

If you have a history of kidney stones, regular follow-up with your doctor is important.

Consult a healthcare professional if you experience:

• Severe pain in your back or side
• Blood in your urine
• Pain during urination
• Frequent urinary tract infections
• Nausea or vomiting associated with pain

Getting evaluated early can help identify the underlying issue and guide the next steps in care.

Almonds do not directly cause kidney stones in everyone. However, because they contain oxalates, excessive consumption may increase the risk of calcium oxalate stones in susceptible individuals.

For most healthy people, almonds can be enjoyed as part of a balanced diet.

If you have a history of kidney stones or chronic kidney disease, speak with your healthcare provider about the right dietary choices for your needs.
