I have been seeing a lot of hype around superfoods and various health foods in recent times. While some of my friends swear by these foods and claim to have seen significant health benefits upon consuming them, I am a bit skeptical. I would like to know if there are any scientific studies that back up these claims. Are superfoods really that good for us, or are they just another marketing gimmick? I want to make informed decisions about what I eat, and I don't want to be taken in by false claims. Can anyone share any research that has been done in this area?
