Reply to this email and let me know!— Alexandra Engler, senior directorShould we rethink tattoo ink?Sorry to be the bearer of bad news, but tattoo ink doesn’t just stay skin-deep. In a new study, researchers analyzed tissue samples from tattooed individuals and found ink nanoparticlesaccumulated in lymph nodes over time.¹The study observed that this accumulation was linked to localized structural changes and immune cell activation—specifically involving macrophages. This could theoretically lead to chronic low-grade inflammation.Pigment composition played a role: inks with titanium dioxide and certain organic pigments were more likely to trigger immune cell engagement.An important caveat? Risks may accumulate over very long timeframes, and many individuals with tattoos have no known adverse outcomes.More research is needed and researchers say this doesn’t necessarily mean immediate health risks, but this study suggests it would be a good idea to know about the ingredients in tattoo ink and gain a greater understanding of its impact on the immune system. +A much-needed boostDon’t forget your immune system relies on thisWhy you should always have ginger aroundThese carbs play a surprising role in immune healthPRESENTED BYIs your running shoe shape & fit wrong?One of the most pervasive myths about running is that pinched toes and aching feet are just part of the deal. The truth is that these are signs your running shoe is all wrong. Altra’s signature fit is designed to keep your feet in a natural position for comfort, balance, and strength. The Altra Fit features:Room for your toes: Narrow toe boxes can increase the risk of physical stress by limiting natural toe splay and changing gait mechanics.² Altra’s roomy toe box means the toes have room to naturally spread out, providing a stable foundation to run on.Zero-to-low drop heal: Research shows that this helps keep the foot in a more natural position, encourage better form, reduce strain on several joints, and improves energy efficiency.³Altra builds shoes around how your feet are actually shaped and how they’re meant to move. Lace up a pair and you’ll experience runs that feel freer, smoother, and more sustainable.Shop nowIf you do one thing… learn a new languageLearning another language isn’t just handy when you travel, it has serious health benefits.

These are 3 foods to have on rotation this winter.
