Both advertising claims I have provided with question mark, why? I daily consume multiple cores and other reviewers - added more expensive - had products, I feel by the words "very high proportion bitter" kidding. So are under 6 cores quite 3 times sweet, at times are actually 6 bitter. I guess 10 - 20 percent are not bitter. "Natural" - when one understands that not a small amount of seeds are extremely foul taste, so that they spit out quickly, so then the statement is true. Of the strongly dried seeds I do not even talking about. My recommendation, rather spend a little more money and buy quality.
