Health Benefits of Legumes

Introduction

Legumes contain nutrients like protein, minerals, vitamins, and starch and are observed as the earliest domestic plants. They are utilised as human and animal food and soil-enhancing ingredients in agriculture and agro-forestry. 

What are Legumes?

Legumes comes under leguminosae family. It is one of the most prominent and principal families of flowering plants representing 650 to 750 genera, 18,000 to 19,000 species of climbers, shrubs, herbs, and trees. 

The podded fruits or legumes generally define this family. It is divided into four subfamilies: Papilionoideae (14,000), Caesalpinioideae (2,800 species), Mimosoideae (2,900), and Swartzioideae (80) 

The most popular and commonly used legumes are chickpeas, cowpeas, kidneys, lentils, alfalfa, clovers, mung beans, peanuts, peas, pigeon peas, and vetches soybeans.  

The nutrition profile of legumes

One-half cup of legumes gives about 115 calories, 7–9 g of fibre, 8 g of protein, 20 g of carbohydrate, and 1 g of fat. They also have a low glycemic index, ranging between 10 and 40.  

Legumes are a great source of nutrients such as protein, starch, minerals and vitamins and main health-protective compounds (phenolics, inositol phosphates and oligo-saccharides) 

The considerable nutritional value of legume seeds provides the required nourishment and food for vegetarians. It acts as a replacement for meat. The isolated proteins, starch and fibres from legume seeds possess excellent physico-chemical and health-protecting characteristics. 

Legumes in our food 

Legume seeds are the primary human food source, second only to cereals. In comparison with cereals, legumes are more rich in protein content. When they are both eaten together, they have complete protein requirements. 

Kidney beans are a significant source of food in Latin America. In contrast, lentils, chickpeas, and pigeon peas are important diets in South Asia, and fava beans, lentils, and chickpeas are the primary protein sources in the Middle East and North Africa. 

Everyday food products made from legumes include peanut butter and soymilk.    

Fodder and Animal Food 

Legumes are also used as animal fodder; soybeans are the most commonly used animal fodder. 

Forage legumes commonly used are grass-legume mixtures, medics, trefoils, clovers, and vetches, which are crucial in temperate regions. 

Lablab, Desmodium, Stylosanthes, Pueraria, and other tropical pasture crops are mainly used as cattle fodder in tropical and subtropical regions.  

Health Benefits 

Lowers the risk of cardiovascular diseases 
 
The high fibre content, low glycaemic index and the presence of minor components like phytosterols, saponins, oligosaccharides, etc., are considered vital responsible agents in regulating lipids and, therefore, decrease the risk of cardiovascular diseases.  
 
Regulates Diabetics 
 
The lower glycaemic index and undigestible fibres of dry legumes are observed to assist glycaemic control in people with diabetes.  
 
Promotes Digestion  

Legumes are assumed to be essential in the accelerated transit of digested food in the intestinal tract.  This accelerated transit and its final excretion play a principal role in decreasing cholesterol re-absorption and incomplete starch digestion and reducing fermentation processes.
