Can You Eat Lemon Seeds? Are They Toxic or Safe to Swallow?

Can I Eat Lemon Seeds?

Lemons are a popular citrus fruit that most people have in their kitchen. They add flavor to dishes, drinks, and baked goods. But what about the seeds inside lemons? Can you eat lemon seeds, or are they toxic and should be avoided?

Lemon seeds are not poisonous or toxic. However, they are very bitter and hard, making them unpleasant to eat. Most people prefer to spit out lemon seeds rather than swallow them. But if you did swallow a few accidentally, you dont need to worry.

Are Lemon Seeds Edible?

Lemon seeds are edible in the sense that they wont harm you if eaten. But they have an extremely bitter, sour taste that makes them unpalatable. The hard, tough texture of lemon seeds also makes them difficult to chew.

The seed consists of the outer coat, pulp, and enclosed embryo which has the capacity to germinate into a new plant. The pulp is the part with the unpleasant taste. The seed coat is also too hard and fibrous to make the seeds worth eating.

Occasionally swallowing a seed or two wont cause any issues. But chomping down on lemon seeds isnt recommended. The taste and texture make them unenjoyable. For these reasons, most recipes call for removing seeds from lemons before using them.

Are Lemon Seeds Toxic?

Rest assured that lemon seeds are not toxic, poisonous or dangerous to eat. They contain complex organic compounds like limonene, phellandrene, pinene and other volatile oils. But these oils dont pose any health risks.

In large quantities, limonene may cause skin irritation. But youd need to eat a huge amount of lemon seeds to reach toxic levels. Swallowing one or two seeds while juicing a lemon wont come close.

Bitter foods like lemon seeds can stimulate digestion by increasing bile production. Some alternative medicine practitioners even recommend eating a small number of seeds as a digestive aid.

So while lemon seeds taste bad, they wont hurt you if ingested. The small quantities found in lemon juice or baked goods are perfectly safe to consume.

Nutritional Value of Lemon Seeds

Most people dont think about the nutritional content of lemon seeds. But they are high in certain vitamins, minerals and plant compounds that may offer health benefits.

According to nutrition data, one teaspoon of lemon seeds contains:

• Calories: 5
• Fat: 0.1 g
• Carbs: 0.8 g
• Fiber: 0.5 g
• Protein: 0.1 g
• Thiamine: 1% RDI
• Riboflavin: 1% RDI
• Niacin: 1% RDI
• Vitamin B6: 1% RDI
• Calcium: 0.5% RDI
• Iron: 1% RDI
• Magnesium: 1% RDI
• Phosphorus: 1% RDI
• Potassium: 1% RDI
• Zinc: 1% RDI

Lemon seeds also contain plant compounds like flavonoids, coumarins, saponins and terpenes. These function as antioxidants in the body to help neutralize free radicals and reduce oxidative stress.

Research shows that foods rich in these types of antioxidants may help prevent chronic diseases like heart disease, cancer and diabetes. This is why a diet high in fruits and vegetables is linked to better health.

However, keep in mind that these are trace amounts. Youd need to eat Spoonfuls of seeds to obtain significant antioxidants from lemon seeds alone.

Can You Grow Lemon Trees From Seeds?

Lemon seeds are viable and can be used to grow lemon trees, if you have patience. The seeds need warm conditions to germinate and should be planted soon after the lemon is squeezed.

Start by drying the seeds for a day or two. Fill small pots with seed starting mix and plant a few seeds in each about 14 inch deep. Water and move the pots to a warm spot with indirect sunlight.

It can take between 2-6 weeks for the seeds to sprout. Once sprouted, transplant the seedlings into slightly larger pots. Fertilize with a citrus fertilizer according to package directions. When the trees are 1-2 feet tall, transplant them outdoors into large pots or the ground.

Citrus trees grow slowly and need full sun. It will take at least 3-5 years for dwarf lemon trees to start producing fruit. Some varieties take much longer. But growing lemon trees from seeds can be an interesting gardening project.

What About Pre-Sliced, Packaged Lemons?

Pre-sliced lemons sold in plastic containers at the grocery store are a convenient shortcut for cooking. But check the package closely. Some brands remove all seeds, while others leave a few in.

If the packaging advertises seedless sliced lemons, then theres nothing to worry about. You can add them to drinks, fish, desserts or anything else without the annoyance of seeds.

However, other brands are less consistent about removing the seeds. Its not uncommon to find 1 or 2 stray seeds hidden in these container of pre-cut lemons.

In these cases, inspect each slice and pick out any seeds you find before using. Or give the lemons a quick rinse in a colander to dislodge most of the seeds if you plan to juice them.

Check labels closely and contact the manufacturer if youre concerned about how thoroughly they remove seeds.

What About Other Citrus Seeds Like Oranges?

The safety and taste of lemon seeds applies to other citrus fruits as well. Seeds from limes, oranges, grapefruit, mandarins and other types are also not toxic, but they are bitter and difficult to chew.

Citrus seeds contain the same types of plant compounds and trace vitamins and minerals. But theyre far too bitter and tough to make eating them worth it.

Accidentally swallowing a few generally isnt harmful. But if you start crunching down on handfuls of citrus seeds, the fibrous texture could potentially cause issues. They may also become lodged in dental work like braces or bridges.

For these reasons, avoid making a habit of eating citrus seeds. Pick them out of fruit before juicing or cooking for the best flavor and smooth texture.

Risks of Eating Lemon Seeds

Although lemon seeds are edible and non-toxic, some potential downsides are worth considering.

Choking Hazard

Lemon seeds pose little risk to adults if swallowed whole. But their small size and hard shell can make them a choking hazard for children.

For very young children, especially those under 3 years old, citrus seeds are on the list of foods to avoid. The American Academy of Pediatrics recommends cutting grapes, hot dogs, popcorn and other small, hard foods into very small pieces to prevent choking.

If you plan to serve lemon water or other lemon-infused dishes to children, be sure to strain out the seeds first. Encourage kids to spit out any seeds if they accidentally ingest one.

Dental Damage

The tough, hardy texture of lemon seeds makes them difficult to bite through. If you try crushing them with your teeth, they could potentially damage dental work.

The seeds can become trapped in braces, bridges and other dental appliances. Their hard shell may also chip teeth if you try to chew them.

To avoid dental issues, keep lemon seeds away from children with braces. Adults with dental concerns should also think twice before deliberately chewing seeds.

Phytates Limit Mineral Absorption

Like many seeds and nuts, lemon seeds contain phytic acid
