New article puts oat milk and soya milk as the most environmentally sound, and both miles and miles ahead of dairy milk. That's handy because oat is by far the best milk out there and I like soya milk too.
Soy: back in favor
Soy milk was the go-to alternative long before almond.
According to the Oxford study, soy milk is the joint winner on the sustainability scale. Plus, soy is the only plant milk that comes close to offering a protein content comparable to dairy. It was the go-to alternative long before almond milk came into vogue – but then soy fell out of favor.
“Soy has a relatively high concentration of certain hormones that are similar to human hormones and people got freaked out about that,” says Emery. “But the reality is you would have to consume an impossibly large amount of soy milk and tofu for that to ever be a problem.” Recent studies have instead found that a moderate amount of soy is healthy, especially for women.
The primary environmental drawback to soy milk is that soybeans are grown in massive quantities around the world to feed livestock for meat and dairy production. Large swaths of rainforest in the Amazon have been burned to make way for soy farms. The work-around for this is to simply do a little research and read the carton to find soy milk that is made from organic soybeans grown in the US or Canada.
Oat: a humble hero
Oat milk ‘performs very well on all sustainability metrics’.
Meet the winner: the unassuming oat.
“I’m excited about the surge in oat milk popularity,” says Liz Specht, associate director of science and technology for the Good Food Institute, a not-for-profit that promotes plant-based diets. “Oat milk performs very well on all sustainability metrics.” Also: “I highly doubt there will be unintended environmental consequences that might emerge when the scale of oat milk use gets larger.”
According to Bloomberg Business, retail sales of oat milk in the US have soared from $4.4m in 2017 to $29m in 2019, surpassing almond milk as the fastest-growing dairy alternative. But unlike almonds, there are already plenty of oats to go around. “Right now, 50 to 90% of global oat production goes into animal feed,” says Specht, “so there’s a huge existing acreage that we can safely steal share from without moving the needle at all on total production.”
Oats are grown in cooler climates such as the northern US and Canada, and are therefore not associated with deforestation in developing countries. The only drawback with this trendy and guilt-free option is that most oats come from mass-produced, monoculture operations where they are sprayed with the Roundup pesticide right before harvest. A study by the Environmental Working Group found glyphosate, the active ingredient in Roundup and a possible carcinogen, in all the foods it tested containing conventionally grown oats and even in one-third of products made with organic oats. However, the popular Oatly brand oat milk company maintains its oats are certified glyphosate free.
A glass of dairy milk produces almost three times more greenhouse gas than any plant-based milk. But vegan options have drawbacks of their own
