Health Benefits Of Lima Beans

1. Prevent constipation

The insoluble dietary fibre in lima beans acts as a laxative that reduces the chances of constipation [3] . Insoluble fibre stays in its fibrous form which helps food pass through the digestive system and increases the bulk of the stool. Eating lima beans can benefit people suffering from constipation or irregular stools.

2. Promote growth and repair of tissues

Lima beans contain a good amount of protein which is important for regulating every single process of the body. Proteins are the building blocks of the body required for the growth and repair of cells and tissues of the body. Proteins help in faster recovery from an injury or illness by boosting up the protein levels in the body[4] .

3. Improve heart health

Lima beans contain significant amounts of dietary fibre, potassium, magnesium, folate and saponin [5] . All these nutrients contribute to cardiovascular health. The fibre lowers the absorption of cholesterol in the bloodstream and reduces blood pressure. Folate reduces the thickening of artery walls, potassium and magnesium reduce the risk of heart diseases.

4. Prevent cancer

The dietary fibre content in lima beans protects the colon mucosa by decreasing its exposure time to toxic substances in the colon. It also acts as a binding agent to cancer-causing chemicals in the colon. Lima beans also contain little amounts of isoflavones like genistein and daidzein which have been found to protect from breast cancer. In addition, lunatusin, a trypsin-stable antimicrobial peptide extracted from lima beans has also been shown to reduce the risk of breast cancer [6] .

5. Stabilize blood sugar

If you have diabetes, lima beans can really help in managing your blood sugar levels due to the presence of dietary fibre. Consumption of lima beans by diabetic patients can help them manage their insulin resistance. Being a low glycemic index food, lima beans will help stabilize the blood sugar levels [7]

6. Increases energy levels

Lima beans are an excellent source of iron, a mineral responsible for increased energy production and metabolism. When the iron stores start depleting in the body, not enough red blood cells are produced to transport oxygen throughout the body. This leads to weakness and low energy levels in the body.

7. Prevent pregnancy-related issues

Both fresh and dried lima beans are a great source of folate also known as folic acid is an important mineral required for pregnant mothers. Folate, when consumed before or during pregnancy, can help prevent neural birth defects of a baby's brain and spinal cord [8] .

8. Help in digestion

The fibre in lima beans keeps the digestive tract healthy by helping in the digestive process and boosting the growth of good bacteria in the gut. Fibre works as a prebiotic that feed the good bacteria in the intestine and lowers the risk factor for obesity and metabolic syndrome [9] .
