Fava Beans Nutrition

Fava beans are a good source of energy, with a 100-gram serving offering 110 kcal of energy. They are rich in protein, carbohydrates, and fiber as per the USDA Nutrient Database. These beans contain slight sugar levels, which gives them their sweet taste. When it comes to minerals, fava beans offer calcium, iron, magnesium, phosphorus, potassium, sodium, and zinc. They also contain various vitamins, including vitamin C, thiamin, riboflavin, niacin, vitamin B6, folate, and vitamin A, E, and K, making them a nutritious and tasty addition to your diet. [3]

Fava Beans Benefits

Given their rich nutrient content, fava beans have many benefits such as treating Parkinson’s disease, preventing birth defects, improving bone health, and fighting anemia. Let’s take a detailed look at them below.

Treat the Symptoms of Parkinson’s

According to a study published in 2013, fava beans, given their rich L-dopa and C-dopa content, help improve the motor performance in those suffering from Parkinson’s disease by increasing the blood dopamine levels. [4]

Another study revealed that when patients with Parkinson’s disease were fed 250 grams or 1.5 cups of fava beans in a day, their blood dopamine levels showed a positive rise similar to the effects of their L-dopa medications. These beans can also be combined with other Parkinson’s disease medications like carbidopa for an improvement in symptoms. [5]

Having said that, it is important not to replace your medically prescribed drugs for Parkinson’s disease with fava beans, as more research on this topic is still needed.

May Prevent Birth Defects

According to the Centers for Disease Control & Prevention, fava beans have a huge supply of folate, with 106% of the recommended daily requirement per 100g serving. Folate is one of the most important nutrients for fetal growth. It helps in the creation of cells and organs for the fetus, thereby preventing the risk of neural tube defects. A study done at the Boston University School of Medicine revealed that women who got an ample supply of folate in the first few months of their pregnancy had a markedly lower risk of spinal cord and brain issues in their infants, thereby making broad beans a good dietary option for them. [6] [7]

Improve Bone Health

Fava beans, being rich in manganese, copper, zinc, and calcium, are known to help improve bone health. As per research, one single cup with a 100 gram serving of fava beans contains 43 mg of manganese. Manganese helps in reducing calcium deficiency in the body, thereby reducing the risk of bone-related ailments like osteoporosis and bone loss in older women. [8] [9]

May Help Fight Anemia

Due to the high iron content in fava beans, they help fight the symptoms of anemia, such as tiredness, weakness, shortness of breath and more. Iron promotes the production of hemoglobin in the body which helps in carrying oxygen to your cells. Hence, regular consumption of fava beans may help prevent anemia too. [10]

Although an important point to note here is that those suffering from a G6PD deficiency, should not consume these beans as they may lead to another blood disorder called hemolytic anemia. [11]

Manage Blood Pressure

Given the high manganese and potassium content in fava beans, they can help in managing your blood pressure. According to studies published on the DASH diet, foods high in manganese and potassium are known to relax the blood vessels and lower high blood pressure, also lowering the risk of a heart attack or stroke. [12] [13]

May Promote Weight Loss

One cup or 170-gram serving of fava beans contain around 180 calories, which makes them a good food option for those looking to lose weight. According to research done at the University of Washington School of Medicine, they also have a rich supply of protein and fiber, which help improve the feeling of fullness in your stomach thereby curbing the need or urge to eat more. [14]

Help Lower Cholesterol Levels

Fava beans are rich in soluble fiber, which helps in binding and removing cholesterol from your body. A study also reveals how soluble fiber helps in decreasing the LDL cholesterol and glucose levels in the body. [15]

Boost Immunity

Fava beans are a rich source of copper, which is an important mineral to regulate the production and growth of healthy blood cells. Copper also promotes the functioning of white blood cells, which destroy the disease-causing pathogens in the body. Research also reveals how broad beans can promote antioxidant or free-radical fighting abilities in people as they age.

Side Effects

It is important to exercise moderation while consuming fava beans as an excess of them can have some side effects.

  • Vitamin B6 deficiency: Fava beans can cause depression if taken in excess. This is due to the presence of L-dopa in them, which although beneficial for health, in excess can cause a vitamin B6 deficiency.
  • Drug interactions: They may also have some drug interactions, so if you’re taking medicines for depression, then it is best to consult your doctor before adding these beans to your diet.
  • G6PD deficiency: Another point to note is that these beans should not be consumed if you have a G6PD deficiency, as already mentioned above.
  • Allergy: Broad beans can also cause an allergic reaction to some people, so be cautious while adding them to your diet.

While the side effects of these beans are rare, they are very much possible, so please see a medical professional if you feel uncomfortable after eating them.
