Tofu ir unikāls ar to, ka tam pašam par sevi nav garšas. Tas, kāds būs izdevies ēdiens ar tofu – salds, sāļš vai ass –, ir pilnībā atkarīgs no tevis, jo tofu „uzsūc” citu ēdienu garšu.
In 1997, about 8% of all soybeans cultivated for the commercial market in the United States were genetically modified. In 2010, the figure was 93%. As with other glyphosate-tolerant crops, concern is expressed over damage to biodiversity. A 2003 study concluded the RR gene had been bred into so many different soybean cultivars, there had been little decline in genetic diversity, but "diversity was limited among elite lines from some companies".
