The topic of starch has become more interesting for me lately. It starts with Ray Peat advocating potato over rice and wheat, to name a few seed-based starches. Potato is a root crop, and it doesn't suffer the stigma of being called a seed. A seed would contain anti-nutrients, is the plant's way of discouraging animals from foraging on it. Anti-nutrients would make the seed more difficult to digest, and would cause irritation and inflammation, and increase the production of serotonin, the downstream effect being less efficient energy production, and over a period of time, degeneration and acceleration in aging.
Potato is just one root crop of many. It has a good amino acid profile, according to Ray Peat. And I'm interested in finding out if it is the best root crop. There are different kinds of yams, sweet potatoes, cassava and there is even an underwater tuber call lotus root. While there isn't much variety in the US, the same cannot be said in Asia.
I took a sampling, and checked on lotus root, and found something interesting. Lotus root has seven times as much glycine than either tryptophan and methionine. On the other hand, potato has twice as much glycine only. Although I'm not qualified to make any judgment on its amino acid profile taken altogether, I wonder if anyone here can.
I readily admit my interest in raising koi led me to look into this. It comes as no coincidence to me that the premium koi food use potato starch, while the regular koi food use wheat. While the price of premium koi food is prohibitive and I haven't used them, the makers of such koi food claim that with the use of potato starch, there is less waste produced over feed made with wheat as binders. Knowing that potato has none of the anti-nutrient properties of wheat, I think the claim is legitimate. Thinking about what possible carbohydrate a koi could eat in the wild, I thought about the lotus root, and imagine the koi dredging up the lake bottom and eating the lotus root.
Anyway, that was just an aside. I now think about hogs and chicken doing the same thing as koi, "dredging up" the land and eating roots and tubers for their carbohydrates. What if we had a root and tuber agricultural economy, and what if we can raise pigs and poultry with these, and have pork and chicken with a lot less PUFA?
