Seed consumption offers substantial nutritional and health benefits for humans. Among non-conventional legumes, guaje (Leucaena leucocephala<\/em>) \u2014a member of the Fabaceae family\u2014<\/strong> stands out for its potential. It is widely distributed throughout Mexico\u2019s tropical and subtropical regions.<\/strong><\/p>\n\n\n\n

This legume is primarily used as animal feed and, to a lesser extent, as a protein source in human diets.<\/p>\n\n\n\n

In culinary contexts, guaje<\/em> is consumed directly or mixed with other ingredients in traditional dishes, forming part of the local food identity in southwestern Mexico.<\/p>\n\n\n\n

Despite its potential, guaje<\/em> remains underrecognized as a high-protein food source: between 25% and 32%, comparable to more popular legumes. This nutritional profile is further enriched with essential amino acids, minerals, and phytonutrients.<\/p>\n\n\n\n

However, one major challenge in its consumption is the presence of mimosine<\/strong>, a non-protein amino acid with toxic properties that limits its safe use as a food.<\/p>\n\n\n\n

The Toxic Mechanism of Mimosine<\/strong><\/h2>\n\n\n\n

Although various studies have explored the effects of mimosine in animals, a safe dosage for human consumption has not yet been determined, and the minimum toxic threshold remains unknown.<\/strong><\/p>\n\n\n\n

Growing global demand for sustainable food sources and environmental concerns have encouraged the shift from animal to plant-based proteins, especially those from underutilized native crops. Assessing the toxicity of plant compounds is a crucial step toward understanding the possible adverse effects of certain substances found in non-conventional legume seeds, such as guaje<\/em>, when they are not properly processed.<\/p>\n\n\n\n

Mimosine\u2019s toxicity has been identified in livestock animals. It works by inhibiting key enzymes in DNA synthesis, halting the cell cycle, and damaging rapidly dividing tissues such as the intestinal lining, bone marrow, and hair follicles.<\/p>\n\n\n\n

Additionally, mimosine molecules readily bind to iron, causing a functional deficiency that affects hemoglobin production and enzymatic activity. In sensitive animals lacking the enzymes needed to metabolize this compound, it can lead to the following health issues:<\/p>\n\n\n\n
