Looking for a healthy pick-me up that may have longevity benefits? Here’s one I like to drink:

All blended together in:

  • 2 cups organic A2 raw milk. There’s some debate about whether milk is good or bad for the heart, with old-guard medical authorities still railing against it; but this study suggests that milk in reasonable quantities is actually highly protective against heart disease:

Is raw milk safe?

  • The FDA’s position is that raw milk is inherently dangerous. This strikes me as inaccurate. There’s of course no guarantee that any food is 100% safe. I buy raw milk from a state-regulated farm which does intensive testing. I get nasal allergies when I drink pasteurized milk; no reaction at all when drinking it raw.
  • This (industry) article explains the reason that some people choose to drink raw milk, and why the farm it’s purchased from can make a difference.
  • I’m not recommending that others drink raw milk, or avoid it – you’ll have to make your own decision – and it’s still illegal in some states in the U.S. (but freely available in others). I’m just explaining why I drink and love it.
  • Side note: In many places in Europe it’s sold freely in vending machines. In the U.S., the. FDS allows sales of Coca Cola and other toxic drinks in vending machines, while prohibiting raw milk:

Do the ingredients really support longevity?

  • It’s unclear whether any diet will really make us live longer. We’d need longer than a human lifespan to find out, and another lifetime to repeat the experiments. So I don’t plan on waiting.
  • All of the ingredients do have anti-aging properties, such as supporting brain health, gut health and heart health.

About malic acid


  • mTOR is the growth pathway. AMPK is the longevity pathway.
  • Some mTOR activation is essential to muscle building and immune health. But if it’s activated constantly, it’s pro-aging. And foods high in leucine, like dairy, do tend to activate it.
  • For this reason, I usually fast till around 1 or 2 pm, then have lunch (breakfast). I deliberately focus on activating mTOR around mealtimes.
  • I then balance this out activating by AMPK when I’m fasting.
  • We’d die if we tried to live with zero activation of mTOR. So my current strategy is to

Was this smoothie palatible?

  • The first time I drank it, I used no sweeteners. It was borderline.
  • The second time, I added the allulose and elderberry syrup, which made it tastier.
  • To my surprise, the smoothie came out thicker than a milkshake, probably because of the malic acid; I had to dilute it to drink it.
