Yes, accidentally eating a few lemon seeds is generally harmless, although they taste bitter and are usually removed. There is little reason to eat them deliberately in large amounts; strain lemon juice if you want to avoid them.
No, lemon seeds are not considered poisonous in the small amounts people might swallow while eating or drinking. Their bitter taste does not mean they are toxic, but they are not normally eaten as a snack.
A swallowed lemon seed will usually pass through your digestive system without causing a problem. Accidentally swallowing one or a few is generally not a concern, though small seeds can pose a choking risk for young children.
Yes, a fresh lemon seed can sprout and grow into a tree. Seed-grown trees may not produce fruit like the parent lemon, and they can take years to fruit, so they are not a quick way to grow lemons.
Lemon seeds taste bitter because they contain naturally occurring bitter plant compounds. Removing the seeds before squeezing or blending lemons helps keep drinks and dishes from picking up that sharp taste.
Lemon seeds are not regarded as a cyanide-poisoning risk when swallowed in the small amounts typically encountered in food. Avoid chewing or deliberately eating large quantities; the ordinary advice is simply to remove them if their bitterness bothers you.
Rinse a fresh lemon seed to remove pulp, then plant it in moist potting soil and keep it warm and bright. Keep the soil damp but not waterlogged; fresh seeds are generally more likely to sprout.
Pour freshly squeezed lemon juice through a fine-mesh strainer to catch the seeds. You can also squeeze the lemon over a small sieve or remove visible seeds with a spoon before using the juice.
There is no good evidence that eating lemon seeds causes appendicitis. A seed swallowed by accident is usually harmless; seek medical care for severe or worsening abdominal pain rather than assuming a seed is responsible.
Lemon seeds are usually removed from recipes because they are bitter and do not add much flavor beyond that bitterness. Strain them out of juice, dressings, or sauces before serving.

Lemon seed is the small, firm seed found inside a lemon. It is not a common food ingredient: most people remove the seeds when squeezing the fruit or preparing slices, rather than eating them on purpose. A seed accidentally bitten into has a distinctly bitter taste, so it can be noticeable even in a drink or dressing.
For lemonade, tea or a salad dressing, strain out the seeds for a smoother sip or bite. Although the nutrition figures per 100 g look concentrated, seeds are usually avoided and a typical serving is only about 3 g, so they contribute little to an everyday meal. For lemon flavour, use the juice or a little zest instead.
Medium
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
