Economy: Food: Big Agriculture designs a new sweet patoto, but what about diabetics like me?

ConAgra is a mega-corporation that dicks around with the genomes of food, and I worry that it's part of obsolescing historic varieties that nature, under God. developed for itself, so to speak. Humans were incidental to the process, except as farmers conducted experimental Mendelian hybriding. Then along came Big Ag in the USA and around the world (the Green Revolution in the Punjab, India). In Louisiana university research is cooperating with ConAgra to develop a new kind of sweet potato. My main question about including sweet potatoes in my diet is precisely their sweetness, their sugar-content. I'm wondering if we're going to have genetically altered sweet potatoes, why do they have to be so sweet? Coudn't a niche product be developed that woud make this variety of "potato" give us more more like a mild tabasco-taste, or a minty taste, or even a licorice taste perhaps? --less sugar, for instance?
