Concord grape seeds are safe to eat. They are small, crunchy, and have a bitter flavor that some people may not prefer, but eating them is unlikely to harm health. Concord grapes can be eaten whole, including the seeds, or the seeds can be spit out after sucking out the juicy pulp. Some people even swallow the seeds whole, and consuming the seeds provides antioxidants, flavonoids, and melatonin, which may offer health benefits. However, people on blood-thinning medications should be cautious as grape seeds and extracts have mild blood-thinning properties. Overall, eating Concord grape seeds is a matter of personal preference and is generally safe.
