Fava beans, or broad beans, are large green legumes that come in pods. Eaten by people around the world, fava beans exhibit a slightly sweet but earthy flavor. They are nutritional powerhouses, providing a variety of health benefits. Naturally rich in fiber, protein, and a variety of other vitamins, minerals, and antioxidants, fava beans may aid blood sugar regulation, support heart health, and boost immunity.Â
Even though fava beans are relatively small in size, they pack a ton of nutrients. They are particularly rich in plant protein, folate, and soluble fiber. One cup of fava beans contains the following nutrients:
- 187 calories
- 33 grams (g) of carbs
- 13 g of protein
- Less than 1 g of fat
- 36% of the daily value (DV) of manganese
- 18% of the DV of magnesium
- 40% of the DV of folate
- 14% of the DV of iron
- 22% of the DV of copper
- 13% of the DV of potassium
- 11% of the DV of thiamine and zinc
May Help Prevent Birth Defects
Folate is essential for creating cells and organs, and it is a nutrient that promotes healthy fetal development. An expecting mother should increase her intake of folate, be it from food or supplements, to help reduce the risk of neural tube defects, or developmental issues with the infant’s spinal cord and brain. One study involved more than 23,000 women and found that the incidence of brain and spinal cord issues was 77% lower in infants of mothers who had the highest daily intake of folate. Since one cup of fava beans contains 40% of the DV of folate, they should be near the top of the list of great pregnancy foods.
May Benefit Bone Health
Fava beans are rich in both manganese and copper, two nutrients that may prevent bone loss. Health experts do know the exact role that these nutrients play in bone health, but animal studies suggest that being deficient in these two nutrients may lead to decreased bone formation. Existing human research suggests that both manganese and copper are integral to bone health. A one-year study in postmenopausal women with weak bones found that taking a manganese and copper supplement along with vitamin D, calcium, and other nutrients, improved bone mass.Â
May Help Lessen Symptoms Of Parkinson’s Disease
Fava beans contain levodopa (L-dopa), a compound that the body converts into dopamine, a neurotransmitter. Researchers note that Parkinson’s disease causes the death of dopamine-producing brain cells. That process can lead to tremors, difficulty walking, and issues with motor function. Eating fava beans may help with some symptoms of Parkinson’s disease, but more research is necessary. One small study involved 11 people with Parkinson’s. Study authors observed that participants who ate 1.5 cups of fava beans after 12 hours without medication had a comparable positive effect on blood dopamine levels and motor function as L-dopa drugs.
May Help Boost Immune Function
Naturally rich in antioxidant compounds, fava beans may help optimize immune function. Antioxidants work to fight free radicals that may cause cell damage, making them vital to your body’s immune defense. One test-tube study found that fav bean extract was able to increase the antioxidant activity in human lung cells by 62.5%. Additionally, fava beans contain compounds that boost the ability of glutathione in human cells, which may help delay cellular aging.
May Help Reduce Blood Pressure
Fava beans contain magnesium and potassium, both of which may relax blood vessels and lower blood pressure. Various studies indicate that the Dietary Approaches to Stop Hypertension (DASH) diet recommends foods high in potassium and magnesium. A 10-year study in 28,349 women found that participants with the highest intake of magnesium were less likely to develop high blood pressure than those with the lowest intake.
May Help Lower Cholesterol
The soluble fiber in fava beans may help promote healthy bowel movements because it absorbs water in the gut. During that process, it forms a gel-like substance and helps soften your stool. Soluble fiber also binds to and removes cholesterol from the body. Several studies indicate that soluble fiber may help lower blood cholesterol levels in healthy adults and those with elevated levels. A review of 10 studies focused on the effects of fiber-rich legumes on cholesterol levels. The review concluded that diets that included these legumes were associated with modest decreases in total and LDL (bad) cholesterol levels.
