Health Benefits of Lupin Beans
Given their robust nutritional profile, the wide range of health benefits lupin beans offer is hardly surprising. They have been associated with potential cardiovascular benefits, including reductions in blood pressure and serum lipids. Moreover, their high fiber content promotes gut health, and their role in blood sugar control could help prevent type 2 diabetes.
It’s worth examining these health benefits in more detail.
Gut Health
The high fiber content in lupin beans serves as a source of prebiotics, enhancing gut health by promoting the growth of beneficial bacteria. Specifically, the fiber in lupin beans encourages the growth of helpful intestinal bacteria such as bifidobacteria.
Furthermore, the fermentation of lupin fiber by these intestinal bacteria results in a lower environmental pH in the gut. This creates a favorable environment for the proliferation of beneficial bacteria, contributing to a healthy gut microbiome.
Therefore, the regular intake of lupin beans can potentially contribute to a healthy gut, a vital aspect of overall well-being.
Heart Health
Lupin beans have shown potential advantages in the realm of heart health. They have been associated with lowering ‘bad’ LDL cholesterol, which contributes positively to heart health. In a clinical trial, supplementation with lupin protein over 28 days resulted in an approximate 4% reduction in LDL levels.
In addition to reducing cholesterol, lupin beans have shown promise in lowering blood pressure, particularly in individuals classified as ‘mild to clinically hypercholesterolaemic’. The intake of lupin fiber may also lead to a reduction in serum lipids, offering further cardiovascular benefits for hypercholesterolaemic individuals. This makes lupin beans a heart-friendly addition to the diet, potentially improving the HDL cholesterol ratio.
Blood Sugar Control
Lupin beans have several benefits for controlling blood sugar levels:
Their low glycemic index makes them a beneficial food.
Their high protein and fiber content contribute to this low glycemic index.
Replacing just 10% of the total ingredients with lupin bean flour can significantly reduce the glycemic index of bread.
Lupin beans have the potential to:
Reduce blood plasma glucose levels, which can be beneficial for supporting weight loss efforts
Be a valuable addition to a balanced diet
Be part of a diet without contributing to weight gain in overweight or obese individuals
Help manage blood sugar levels, offering potential benefits for individuals with diabetes
Early research indicates that eating lupin beans, which are derived from lupin seed, may provide these potential benefits of lupin, similar to those found in mung beans.
Culinary Uses of Lupin Beans
