This image is a “balloon race”. The higher a bubble, the greater the evidence for its effectiveness. But the foods are only effective for the conditions listed inside the bubble.
You might also see multiple bubbles for certain foods. These is because some foods affect a range of conditions, but the evidence quality varies from condition to condition. For example, there’s strong evidence that Garlic is good for blood pressure. But evidence for its anti-cancer effects is conflicting. In these cases, we give a supp another bubble.
This visualisation generates itself from this Google Doc. So when new research comes out, we can quickly update the data and regenerate the image. (How cool is that??)
As ever, we welcome your thoughts, crits, comments, corrections, compliments, tweaks, new evidence, missing supps, and general feedback. Thank you!
