Is it okay to juice apples with the seeds?

According to the Centers for Disease Control and Prevention (CDC), a fatal oral dose of cyanide is typically 1–2 mg per kilogram of body weight. Juicing apples with the seeds is not recommended, as the process crushes the seeds and releases a compound that can convert into toxic cyanide in the body. While a few accidental seeds are unlikely to cause harm, consistently juicing them increases your risk.

Quick Summary

It is inadvisable to juice apple seeds due to the presence of amygdalin, which becomes toxic cyanide when crushed. While small amounts are not harmful, regularly consuming juice with pulverized seeds is a health risk. Proper preparation by removing seeds is the safest practice for homemade juice.

Key Points

• Cyanide Risk: Juicing crushes apple seeds, releasing amygdalin which the body can convert into toxic hydrogen cyanide.

• Minimal Accidental Risk: Swallowing a few whole seeds accidentally is unlikely to cause harm, but consistent juicing of crushed seeds increases risk.

• Amygdalin is the Key: The compound amygdalin is locked within the seed's tough outer coat and is only released when pulverized.

• Core and Remove: The safest practice is to always core apples and remove the seeds before juicing to eliminate any potential toxicity.

• Health Benefits Elsewhere: All the primary nutritional benefits of apples, including antioxidants, vitamins, and fiber, are found in the flesh and skin, not the seeds.

• Children are More Vulnerable: Children are at a higher risk due to their smaller body weight and lower tolerance for toxins, so taking precaution is especially important.

Why Juicing Apple Seeds Is Not Recommended

Apple seeds contain a compound called amygdalin, a cyanogenic glycoside that turns into toxic hydrogen cyanide when it is crushed, chewed, and metabolized by the body's digestive enzymes. When you bite into a whole apple, the seeds often pass through your digestive system unharmed, protected by their tough outer shell. However, the high-speed processing of a juicer or blender pulverizes these seeds, breaking down their protective casing and releasing the amygdalin into your juice.

The risk of acute cyanide poisoning from juicing a few seeds is low for an average adult, but the danger increases with the quantity of crushed seeds consumed. Moreover, the exact amount of amygdalin varies by apple variety and other factors. Experts from organizations like the Maryland Poison Center and medical professionals consistently recommend avoiding intentional consumption of crushed apple seeds.

Cyanide Toxicity: Symptoms and Risk Factors

Cyanide is a potent poison that interferes with the body's ability to use oxygen, which can be particularly dangerous for vital organs like the heart and brain.

Symptoms of Mild Cyanide Poisoning

• Headache
• Dizziness
• Nausea
• Rapid breathing

Symptoms of Severe Cyanide Poisoning

• Low blood pressure
• Seizures
• Loss of consciousness
• Coma or death

While consuming a few crushed seeds is unlikely to cause severe symptoms, chronic exposure to low doses over time could have adverse effects. It's a precaution that is easy to take by simply coring the fruit before juicing.

How to Safely Prepare Apples for Juicing

To ensure your homemade apple juice is both delicious and safe, proper preparation is key. Follow these steps to enjoy the maximum benefits of juicing without the risks.

1. Wash Thoroughly: Clean your apples under running water. If you are not using organic apples, you can soak them in a mixture of water and a splash of vinegar to help remove wax and pesticide residues.
2. Core the Apples: Use an apple corer or a paring knife to remove the entire core, which contains the seeds. Discard the core and seeds.
3. Cut for Your Juicer: Slice the apples into pieces that are small enough to fit comfortably into your juicer's chute.
4. Decide on Peeling: Peeling is optional. The apple's skin is packed with fiber and nutrients, so keeping it on can increase the health benefits of your juice.
5. Juice and Enjoy: Run the prepared apple pieces through your juicer and enjoy your fresh, healthy juice immediately for the best flavor and nutritional value.

Comparison: Juicing with vs. Without Seeds

Aspect	Juicing Without Seeds (Recommended)	Juicing With Seeds (Not Recommended)
Safety	High. Eliminates the risk of cyanide exposure.	Low. Grinding the seeds releases toxic amygdalin into the juice.
Nutritional Profile	High in vitamins, antioxidants, and fiber (if skin is included). Focuses on the beneficial parts of the apple.	Negligible change to overall nutritional benefit. The small amount of bacteria in the core doesn't outweigh the risk of toxicity.
Flavor	Pure, sweet apple flavor. Can be customized with other fruits and vegetables.	Can introduce a slightly bitter, almond-like flavor from the crushed seeds.
Equipment Wear	Less wear and tear on juicer blades and motor, as the seeds and hard core are removed.	Can cause unnecessary strain on your juicer, potentially shortening its lifespan.

The Verdict on Juicing Apple Seeds

The risk of immediate, severe harm from accidentally juicing a small number of apple seeds is minimal for a healthy adult, as the body can process tiny amounts of cyanide. However, the intentional and regular juicing of apple seeds is an unnecessary health risk. The act of crushing the seeds during the juicing process is what makes the amygdalin bioavailable, converting it into cyanide.

The most nutritious and delicious parts of the apple are the flesh and the skin. These parts provide antioxidants, fiber, vitamins, and minerals that contribute to overall health, from boosting immunity to supporting digestion. Therefore, for the safest and most beneficial homemade apple juice, always take the small extra step of removing the core and seeds before you begin. This simple practice ensures you can enjoy your fresh juice with peace of mind.

Conclusion: Prioritize Safety for Your Homemade Juice

While the prospect of juicing a whole apple may seem convenient, the consensus from health experts is clear: it is not okay to juice apples with the seeds. The potential for cyanide exposure, even if the risk of immediate poisoning is low, makes it an inadvisable practice. The benefits of fresh apple juice come from the fruit's flesh and skin, and there are no significant nutritional gains from adding the seeds. By simply removing the core and seeds, you can eliminate any risk and ensure that your homemade juice remains a healthy and safe part of your diet.

Frequently Asked Questions

Why do apple seeds contain cyanide?

Apple seeds contain amygdalin, a natural compound that, when chewed or crushed, can break down and release hydrogen cyanide in the body.

How many apple seeds would be toxic?

A fatal dose of cyanide requires consuming a large number of crushed seeds, often estimated in the hundreds, though the exact amount varies depending on body weight and apple variety.

Does the cyanide from apple seeds accumulate in the body?

No, cyanide is rapidly cleared from the body. It does not accumulate over the years from small, accidental ingestions.

Can I juice the core but just remove the seeds?

Yes, some experts say the rest of the core, excluding the seeds, is edible and contains beneficial fiber. However, the best practice is to remove the entire core to ensure no seeds are left behind.

What happens if I accidentally juiced a few seeds?

If you accidentally juice a few seeds, it is highly unlikely to cause harm to a healthy adult. The concentration of cyanide would be too low to be dangerous.

Is it safe to juice apples with the skin on?

Yes, juicing apples with the skin on is safe and recommended. The skin is full of beneficial nutrients, fiber, and antioxidants that enhance the health benefits of your juice.

Are seeds from other fruits like pears and cherries also a risk?

Yes, other fruits in the Rosaceae family, including pears, apricots, and cherries, also contain amygdalin in their seeds or pits and should be avoided when juicing or blending.

Can children be more affected by apple seeds?

Yes, children have a smaller body weight, which means a smaller dose of cyanide could be more dangerous. It is always wise to remove seeds before giving apples or juice to children.

Does heating apple juice destroy the cyanide?

Yes, the pasteurization process for commercial apple juice involves heating, which can cause cyanide to vaporize and reduces the amount of amygdalin.
