What Your Saltshaker Says About How You’ll Age
Key Takeaways:
- Men are more likely to reach for the saltshaker. In a study of 8,300 Brazilian adults over 60, about 1 in 8 men and 1 in 10 women reported adding salt at the table.
- Women’s salt habits track more closely with overall diet quality. Among women, extra table salt was more common when ultra-processed foods were frequent and fruits and vegetables were scarce—and less common when produce intake was higher.
- Salt use reflects routine, not just taste. Living alone, everyday food choices, and whether people follow special diets all shaped salt habits, suggesting simple environmental tweaks could gently reduce discretionary salt use.
Who actually reaches for the saltshaker— and what does that say about the rest of their plate? A new analysis of more than 8,300 Brazilian adults over 60 looked at “discretionary” salt use: adding salt to food at the table, after cooking. The researchers found that this habit was still relatively common, but far from universal—and that it clustered with specific lifestyle and dietary patterns in surprisingly different ways for men and women.
Do Salt Habits Differ by Gender and Lifestyle?
Overall, 10.9% of older adults reported salting at the table, with men leading the pack: 12.7% of men versus 9.4% of women. For men, only two factors really stood out. Those who lived alone were substantially more likely to add salt, and those following special diets that restricted salt were much less likely to do so. In other words, social context and explicit dietary guidance seemed to be the main levers shaping men’s behavior.
For women, the picture was more nuanced. Women who did not follow special diets were more likely to reach for the saltshaker, but so were those who often ate ultra-processed foods or lived in urban areas. By contrast, regularly eating fruits and vegetables was associated with a markedly lower likelihood of adding extra salt at the table. That pattern suggests that, at least in this cohort, table salt use may be a rough proxy for overall dietary pattern, especially in women.
Habit, Taste, and Easy Levers for Change
The team notes that adding salt is often as much about habit as flavor. Repeated exposure to high-sodium foods can dull sensitivity to salt, nudging people toward a preference for more intense saltiness over time. But it can also simply be an automatic behavior: the saltshaker is there, so we use it.
Encouragingly, the authors highlight low-friction strategies that could help dial back discretionary salt without sacrificing enjoyment. These include using herbs, natural seasonings, and acidic ingredients like citrus to boost flavor complexity, as well as avoiding the automatic placement of saltshakers on the table. The takeaway is less about obsessing over every grain of salt and more about recognizing that small, repeated habits—what we put on the table, who we eat with, and how often ultra-processed foods crowd out plants—shape our long-term relationship with sodium.
