From tacos to fruit bowls, lime isn’t just flavor — it’s a cultural habit with documented benefits for immunity, digestion, and heart health.
In many Latino households, especially Mexican ones, lime isn’t a garnish — it’s a daily essential. A small green limón sits on kitchen counters and restaurant tables alongside salt, ready to be squeezed over tacos, soups, seafood, fruit, and even snacks. But beyond tradition and taste, nutrition science suggests this habit carries real health implications.
Mexico is the world’s second-largest producer of limes, according to the Food and Agriculture Organization of the United Nations, and consumption is woven into everyday eating rather than reserved for special dishes. That frequency matters.
“Citrus fruits like lime are one of the most accessible sources of vitamin C globally,” the U.S. Department of Agriculture notes, and even small amounts consumed regularly can contribute meaningfully to daily nutrient intake.
One tablespoon of fresh lime juice provides vitamin C, flavonoids, and citric acid — compounds linked to immune support, iron absorption, and reduced inflammation. For communities where iron-deficiency anemia remains a public-health concern, particularly among women and children, this combination is significant. The National Institutes of Health has documented that vitamin C enhances absorption of non-heme iron found in beans, lentils, and leafy greens — staples in many Latino diets.
Lime’s citric acid also plays a role in digestion. Gastroenterologists cited by the Cleveland Clinic explain that acidic foods can stimulate digestive enzymes, which may reduce bloating for some people. Separate studies published in the Clinical Journal of the American Society of Nephrology suggest citrate intake may help lower kidney stone risk by increasing urine pH and volume.
There’s also emerging evidence linking citrus consumption to cardiovascular health. Flavonoids found in limes have been associated with reduced LDL cholesterol and improved blood vessel function, according to research summarized by Harvard’s T.H. Chan School of Public Health.
Still, health experts urge moderation. Excessive lime or lemon juice — especially taken straight — can erode tooth enamel and trigger acid reflux. The American Dental Association recommends consuming acidic beverages with meals and rinsing with water afterward.
Nutritionists generally advise adding lime juice to water, soups, or meals rather than drinking it concentrated. That mirrors how lime has traditionally been used across Latin America: integrated, balanced, and consistent.
In that sense, lime’s benefits aren’t about superfoods or trends. They’re about how cultural habits — practiced daily and shared across generations — quietly support health long before science catches up.
