Subscribe for free to Dr. Greger’s videos at DESCRIPTION: The secret to naturally boosting serotonin levels in the brain may include eating foods such as pumpkin seeds with a high tryptophan to total protein ratio. This may help explain why studies show that those eating plant-based diets have superior mood states. This is the final video of a four-part series (mentioned in Uprooting the Leading Causes of Death [ on natural ways to boost serotonin in the brain. Wednesday’s video-of-the-day Human Neurotransmitters in Plants ( noted that plants themselves can contain serotonin. Thursday’s video The Wrong Way to Boost Serotonin ( was a cautionary tale about tryptophan supplements and Friday’s video A Better Way to Boost Serotonin ( covered the role carbs can play in boosting tryptophan transport into the brain. The findings of better mood scores in those eating vegetarian is consistent with both cross-sectional ( and interventional ( findings I’ve reported previously. The reason I report more data on nuts than seeds is due to researchers’ greater access to funding for studies involving nuts (thanks to producer groups). From what little data we have, though, I have a feeling it’s like the soy versus other beans story ( If I had to guess, I’d bet that, in general, seeds may be even healthier than nuts, and since I encourage daily nut consumption

  1. how did you consume the seeds? Ive always been wary of eating the seed, rather than planting it for more harvest, the theory behind it.
    but, I need to up my serotonin and trypto while laying off the meats, so share more details please..

  2. Btw, I tried this, ate 1/4 cup of pumpkin seeds (pepitas) seperate from other proteins in the morning. By night time I was slap happy. I also took them with a b complex which is required to convert 5 htp to serotonin.

  3. LOL! Maybe that’s way his voice sounds so weird that i miss half the message!

  4. Awesome video, great information, thanks. 

  5. What is the recommended amount of Butternut Squash seed one should take? Which carb is best to take with it? How do they compare to pumpkin seeds for raising serotonin? Also, does one get the same benefit from Pumpkin Seed Oil as from the pumpkin seeds?

  6. im a fan of tripping on tryptophan

  7. Thank you so much for this video! I’ve been experimenting with dates in recipes and avoiding most all other sweeteners on your list for the last few years and I’m thrilled that I’ve made the healthiest choice :)

    Where do Stevia and Erythritol fall among these sweeteners? I’ve been dubious and actively avoiding both, but my dad keeps trying to convince me they’re both the best/healthiest sweeteners (and that dates are no better than HFCS or Agave Nectar… Hm). Just curious how they rate.

  8. Agave is REALLY bad for you, its around 90% fructose or so! Oo

  9. This guy is trying to be dramatic (which I have no problem with), but he comes-off as very annoying. Delivery aside, he provides good, basic information (to be used as a starting basis for further research, of course).

    It’d be wonderful if you could post your comment to this specific video on nutritionfacts. org. This way more people benefit from the dialogue, and I can actually provide you with links in my response (which I can’t do on Youtube). Thanks!
