GLP Podcast: Plant-based meat ain’t so ‘green’? Science of fasting; ‘Monoculture’ myths debunked

• Viewpoint: Is cell-based meat oversold as a sustainability solution?

Is “alt-protein,” meat made from plants, fungi and animal cells, a viable tool in our fight against climate change? The evidence isn’t as clear as proponents of Impossible burgers and similar products say. When we consider all the data, what can we say with confidence about the benefits of alternative proteins?

• Most humans eat three meals a day. Is that what’s best for our health?

Many of us take for granted that eating three meals a day is optimal. As it turns out, three squares a day is more a cultural artifact than a science-based conclusion. Some people do indeed thrive when they eat frequently throughout the day, but others may do just fine on one or two meals a day. The fact of the matter seems to be this: the “right” eating habits likely differ based our genetic makeup and individual preferences.

• Does crop genetic engineering promote monoculture, as anti-GMO activists claim?

Does growing the same crop year over year jeopardize our food system? There is some validity to this concern hypothetically; however, the situation is more complicated in practice. Many farmers do not grow the same crop every season. And those who do often have good reasons for doing so. To what extent are monocultures a problem, and are GMOs to blame for our “dependence” on monocultures?
