Federal nutrient database findings show several plant-based foods provide at least one-fifth of the recommended daily iron intake per cooked cup.

Newly highlighted nutrient data drawn from the U.S. Department of Agriculture indicates that eight vegetables and legumes each deliver more than 19 percent of the recommended daily iron intake per cooked cup, offering measurable plant-based sources of the mineral essential to human health.
The figures, compiled from the agency’s FoodData Central system, align with federal dietary standards that set the Daily Value for iron at 18 milligrams for individuals over the age of four. According to reporting from Health.com, published in March 2026, several commonly consumed vegetables meet or exceed this benchmark, with some approaching or surpassing one-third of the daily recommendation.
Among the highest contributors are lentils and spinach. A single cooked cup of lentils provides 6.59 milligrams of iron, equivalent to 37 percent of the Daily Value, while boiled spinach delivers 6.43 milligrams, or approximately 35.7 percent. Both foods are widely recognized not only for their iron content but also for supplying additional nutrients, including fiber, vitamins, and essential minerals.
Chickpeas, also referred to as garbanzo beans, rank among the top sources as well, containing 4.74 milligrams of iron per cooked cup, or 26.3 percent of the Daily Value. Other vegetables identified in the dataset include Swiss chard, parsley, and leeks, each providing roughly one-fifth of the daily recommended intake. Swiss chard contributes 3.96 milligrams per serving, while parsley and leeks offer about 3.7 milligrams per cup.
The list is completed by edamame and dandelion greens. One cup of cooked edamame contains 3.52 milligrams of iron, or 19.6 percent of the Daily Value, while dandelion greens provide 3.55 milligrams, or 19.7 percent. These foods also contribute a range of additional nutrients, including vitamins A and K, potassium, and other compounds identified in nutritional analyses.
Iron present in plant-based foods is classified as non-heme iron, which differs from the heme form found in animal products. According to the Health.com report, non-heme iron is absorbed at lower rates, typically estimated between 2 and 10 percent depending on dietary conditions, compared to higher absorption rates associated with animal-based sources.
Research cited by NaturalNews.com indicates that pairing plant-based iron sources with foods rich in vitamin C may improve absorption efficiency. Additional preparation methods, such as boiling, can reduce naturally occurring compounds like oxalates that may limit the body’s ability to utilize iron from vegetables. The Health.com report notes that reducing these compounds can help improve nutrient availability.
The findings are presented within the broader context of dietary intake trends and nutrient availability. Analysts cited by NaturalNews.com have raised concerns about declining mineral content in modern diets, attributing the issue to factors such as soil depletion and increased reliance on processed foods.
The USDA data provides a reference point for evaluating plant-based dietary sources of iron, particularly for individuals seeking alternatives to animal-based nutrition. While absorption differences remain a consideration, the identified vegetables represent measurable contributors to daily iron intake when incorporated into balanced dietary patterns.
