I'll agree with the diet blu is on yeah I I'm with you on that. Poor deluded girl who bought some smucksters book
But let me tell you Food science studies are also well outdated in many many areas. - look for example at todays typical dieticians- they are trained to the obsolete food pyramids (funny that was revised not so long ago eh?) But anyway our knowledge is changing all the time. If I had to state what the biggest threat to our food supply was I'd say the lack of minerals in our soils. That and GMO seed, false labelling and Chinese tampering.
I like to think that I stay up to date on food science. I argue consistently with supposed dieticians and in fact I promote the intake of certain fats, which really peeves some of them off. Some of them did a few courses in uni and haven't bothered to stay up to date with things.
GMO foods I have dealt with time and time again. We've been eating GMO since farming became commercial thousands of years ago already...
