Why Do We Smell Different As We Age? Let’s be honest — no one wants to admit they might have a “scent.”“old person smell” is real.

In fact, a 2001 study by researchers at the Shiseido Research Center in Japan found that 2-Nonenal is only detectable in people over 40 — and becomes significantly more common after 60.more sensitive to with age.
So, what can we do?
Curious what they are?Let’s start with something red, juicy, and surprisingly powerful…
1. Tomatoes: Nature’s Internal Deodorant You’ve probably heard that tomatoes are good for your heart.smell better from the inside out?
Tomatoes are rich in lycopene , a powerful antioxidant that helps reduce oxidative stress in the body.2-Nonenal — the one behind the “old person smell.”
Here’s how it works: when your body has lots of antioxidants, it’s better equipped to neutralize the unstable molecules (free radicals) that lead to the breakdown of fatty acids on your skin.
Plus, tomatoes are high in water content and vitamin C, which both support healthy skin and hydration — two more factors in keeping body odor at bay.
A 2022 study from the UK even found that consuming tomato juice daily helped reduce body odor levels in healthy adults over a 2-week period.
So whether you’re slicing them into salads, juicing them for breakfast, or tossing them into pasta — tomatoes may be helping you more than you think.
🍅 Hot Tip: Go for cooked tomatoes (like in sauce or soup) if you want extra lycopene power — it becomes more absorbable when heated.

Ergothioneine is a powerful antioxidant amino acid that helps reduce inflammation and protects your skin’s fatty acids from breaking down — which is key because this breakdown creates the smelly culprit, 2-Nonenal.University of Texas MD Anderson Cancer Center
On the other hand, spermidine activates a natural cell cleanup process called autophagy . Think of autophagy as your body’s “housekeeping service,” clearing out damaged cells and making room for fresh, healthy ones.
