Fairlife is the brand name for a new product from Coca-Cola that many are calling "designer milk." It looks and tastes (more or less) like regular milk but if you look at the nutrition facts panel, you'll see a very different picture: Compared with regular milk, Fairlife ultra-filtered milk is 50 percent higher in protein, 30 percent higher in calcium, and 50 percent lower in sugar.
We can take milk, or leave it. Take milk fat, or leave that. Either way, we can have a good diet of wholesome foods in sensible combinations -- or not. But either way, we need to take seriously the reverberations of our dietary choices across the landscape of a shrinking planet, and the legacy of kindness or cruelty by which history will be invited to judge us.
