Side Effects of Tomato Seeds

Tomato seeds are the small, oval-shaped structures found within the flesh of a tomato fruit. They are reproductive structures that contain the genetic information necessary for growing a new tomato plant. Each tomato seed has the potential to develop into a fully grown tomato plant under the right conditions.

When a tomato fruit matures and reaches its full size, the seeds within it also mature. These seeds can be collected and used for various purposes, such as planting new tomato crops, gardening, or even for culinary uses like making sauces or condiments.

Tomato seeds are often surrounded by a gel-like substance that contains chemicals which inhibit germination. This gel coating helps protect the seeds within the fruit while it’s still on the plant. When tomato fruits naturally decompose, the gel coating breaks down, allowing the seeds to come into contact with the soil and water, which triggers germination and new plant growth.

In agriculture and gardening, tomato seeds can be harvested, processed, and stored properly for use in growing new tomato plants. They can be planted in soil, provided with proper water and sunlight, and given the necessary care to grow into mature tomato plants that produce fruits with more seeds, continuing the reproductive cycle.

Tomato seeds are not poisonous, but the tomato plant contains a toxic Alkaloid known as Solanine. However, the concentration of this toxin is high in the stems and leaves. The presence of Alkaloid in tomatoes helps in making the plant

unappealing to the animals. Moderate intake of tomatoes with the seeds will not impact health, but people suffering from gastrointestinal issues must avoid the intake of raw tomatoes or tomato seeds as its acidic nature may trigger heartburn and have adverse effects on the digestive system.

Here are some possible side effects:

  • Digestive Discomfort:

Tomato seeds have a tough outer covering that might be difficult for some people to digest. Eating a large number of seeds, especially if not properly chewed, could lead to gastrointestinal discomfort, including bloating, gas, or indigestion.

  • Allergic Reactions:

In rare cases, some individuals might be allergic to components present in tomato seeds. Allergic reactions can vary from mild symptoms like itching or hives to more severe reactions like difficulty breathing or anaphylaxis. If you suspect an allergy, it’s important to seek medical attention.

  • Antinutrient Content:

Tomato seeds contain compounds known as lectins and phytates, which can interfere with the absorption of certain minerals like iron, calcium, and zinc. However, the levels of these compounds in tomato seeds are relatively low and might not be a major concern unless consumed in very large quantities.

  • Kidney Stones:

Tomato seeds are a source of oxalates, which are compounds that can contribute to the formation of kidney stones in individuals predisposed to this condition. However, the oxalate content in tomato seeds is not particularly high, and consuming them in moderation is unlikely to cause kidney stone issues for most people.

  • Gastrointestinal Irritation:

Some people might be sensitive to the fibers and other components in tomato seeds, which could lead to irritation of the gastrointestinal tract. This might manifest as stomach discomfort, cramps, or a feeling of heaviness.


For most people, the occasional consumption of tomato seeds along with the rest of the fruit is not likely to lead to these issues. If you have concerns or experience any adverse effects after consuming tomato seeds, it’s a good idea to consult a healthcare professional for personalized guidance. It’s important to note that these potential negative effects are more likely to occur if you consume a large amount of tomato seeds, which is not typical in most diets. Moderation is key, and for most people, including tomato seeds as part of a varied and balanced diet is unlikely to cause any significant problems.
