Grape seeds are small, crunchy, pear-shaped seeds found in the middle of seeded grapes. . . . While they may not be the tastiest, they’re harmless for most people to eat. If you choose not to spit them out, it’s OK to chew and swallow them. In fact, ground up grape seeds are used to make grape seed oil and grape seed extract, which have become popular health foods. However, certain populations may want to avoid eating grape seeds. Some research has found that grape seed extract has blood-thinning properties, which could interfere with blood-thinning medications or be unsafe for people with bleeding disorders.
