We’ll get behind any health trend that approves of butter, so we’ve been on the Bulletproof coffee train since it swept the country last year. The technique of adding a few tablespoons of grass-fed butter to your morning cup of joe might seem strange, but it’s garnered a devout following and sparked a larger movement, the Bulletproof diet, aimed at increasing energy through efficient eating.
The creator of this school of thought, Dave Asprey, recently came out with a follow-up cookbook, Bulletproof: The Cookbook (Rodale, $26.95), with recipes that fulfill his mission of eating a diet heavy in vegetables, protein and healthy fats, with occasional carbs and limited sugars.
And once again, he’s shaken up our mentality about morning beverages with his concept for warm smoothies. That’s right—according to Asprey, it’s time to heat up the contents of your blender: “Drinking something cold in the morning is jarring at best,” he says. “It’s also a shock to the system.” But there’s a nutritional argument as well: kale, the health-food darling, is actually better for you when cooked. Raw kale has high levels of oxalic acid, which can be tough on the kidneys.
At first, we were skeptical about slurping down a piping cup of smoothie, but the steamed kale and pineapple concoction (see recipe) is actually the perfect entry into a cold winter day. The jury’s still out as to whether we continue the habit as the temperature warms up.
Warm Steamed Kale & Pineapple Smoothie
Recipe adapted from Bulletproof: The Cookbook
- 1 cup packed chopped kale leaves (center ribs removed)
- 1 cup chopped pineapple
- 1/2 avocado, peeled
- 1 teaspoon fresh lime juice
- 2 tablespoons high-quality, heat-stable protein powder
In a saucepan fitted with a steamer insert, bring a cup or so of water to a simmer. Add the kale, cover, and steam until cooked, about five minutes. Transfer the kale to a blender. Measure out 1/4 cup of the steaming water, add to the blender along with the pineapple, avocado and lime juice, and blend until smooth and creamy. Add more hot water if you want a thinner consistency. If desired, for extra protein, add the protein powder and lightly blend until the protein is mixed in.
