Lentils are a
powerhouse of nutrition. They are a good source of potassium, calcium, zinc,
niacin and vitamin K, but are particularly rich in dietary fibre, lean protein,
folate and iron. The Centres for Disease Control and Prevention reports that
eating plenty of nutrient-dense foods like lentils can lessen your risk of many
serious medical problems. Lentils are not only one of the oldest commonly
consumed legumes in history, but they are also one of the simplest to prepare
since they don't require a lengthy soaking time like other beans. Some people
may experience flatulence and abdominal discomfort when initially adding
legumes like lentils into their diet. Cookbook author Mark Bittman recommends
incorporating lentils into regular meals slowly, over a period of weeks, and
using a commercial digestive aid.
A single cup of cooked lentils contains 16 grams of dietary fibre.
Lentils contain some soluble fibre, but are an outstanding source of
insoluble fibre. According to The Cancer Project, a diet that includes plenty
of insoluble fibre can regulate bowel movements, promote digestive system
health and may significantly decrease the risk of colon, breast, throat and
esophageal cancer. Fibre-rich foods like lentils may also help prevent stroke,
heart disease, diabetes, high blood cholesterol and hypertension.
Lentils, as an ancient food source, has been
known to mankind for a very long time. The cultivation of lentils is as old as
early agriculture. It provides lot of health benefits, which include the
following:
Good for Muscle Generation:
Our organs and muscles need a constant supply of protein for
repair and growth of the body. Lentils,
especially sprouted lentils, contain all the essential amino acids that are
needed by our body for good muscle-building and smooth functioning of the body.
Controls Diabetes: A study conducted by Anderson and Bridges showed that in the
various categories of foods, dietary fibre was found to be high in the case of
the legume family. Lentils, along with beans and peas, belong to the legume
family. Dietary fibre found food such as
lentils helps in controlling blood sugar levels. Dietary fibre slows down the
rate at which food is absorbed by the blood and thus maintains the sugar level
constantly.
Improves Digestion: As lentils contain high levels of dietary fibre, it improves
digestion if consumed regularly. It also helps in easy bowel movement,
resulting in decreased constipation.
Heart Health: Lentils, with their negligible amounts of fat, are an ideal
source of protein without adding any extra fat to the body, thereby promoting a
healthy heart. Lentils contain magnesium, which helps in relaxing
cardiovascular muscles and helping to lower blood pressure.
Prevents
Atherosclerosis: Research conducted by Xu, Yuan,
and Chang at the Department of Cereal and Foods Sciences in North Dakota showed
that the consumption of lentils provides a supply of antioxidants that
decreased the chances of developing atherosclerosis. Also, these antioxidants
play a role in neutralizing free radicals and thereby preventing cell and gene
damage (aging).
Counteracting
Cancer: Studies conducted by Elvira González De Mejía & Valentin I.
Prisecaru at the University of Illinois have found that plant lectins, a
separate type of plant protein originating from foods like lentils, wheat,
peanuts, peas, and soybeans have a great influence on cancer cells. Research
studies have shown that these lectins cause cytotoxicity and apoptosis, which
means that they have a great potential to control cancer growth.
Good Source of Folic
Acid: Lentils are a good source of Vitamin B-complex, such as folate
or folic acid. The consumption of folic acid by pregnant woman helps in
preventing birth defects. According to study by Susan J Duthie, at the Rowett
Research Institute in Aberdeen, UK, a lack of folic acid often results in
neural tube defects. Folate found in
lentils helps in the formation of red blood cells, is good for pregnant women,
and plays a key role in maintaining homocysteine levels. It is also known to be
effective against hypertension and DNA damage, which may result in cancer.
Weight
Management: Research studies suggest that the regular consumption of lentils
can help in weight control and increase satiety.
Healthy Nervous
System: It was long believed that micronutrients such as vitamins and
minerals did not have an effect on the functioning of the brain. However,
further research suggested that for the proper functioning of the brain,
vitamins and minerals are equally important. According to the research
conducted by J.M. Bourre at the Department of Neuro-pharmaco-nutrition at
Fernand Widal Hospital in Paris, vitamins and minerals found in lentils are
helpful in optimum brain functioning.
High Iron Content: Lentils contain high amounts of iron, which is needed by the
body for optimum haemoglobin production. About 36% of the iron of the Daily
Recommended value can comes from eating 1 cup (200 grams) of lentils every day.
Improved
Electrolytic Activity: Potassium, one of the minerals
found in lentils, is regarded as a better substitute for electrolytic activity
than sodium. Many diseases have been associated with a high sodium content and
a low potassium content in the body. Apart from acting as an electrolyte,
potassium is also helpful for the functioning of a number of organs like the
heart, brain, and kidney.
Boosts Metabolism: Lentils are a good source of many vitamins, including vitamin
B3, which plays a significant role in boosting the digestive and nervous
systems. Vitamin B3 offers many other benefits, including cholesterol control,
a decreased risk of diseases like Alzheimer’s disease, cataracts,
osteoarthritis, and diabetes.
A Few Things to Consider:
Although lentils are good for your health and
are the best alternative for meat, poultry, and fish, they also have few
disadvantages, which include:
Risk of Kidney Stones: Research conducted by Massey et al. at the Washington State
University’s Department of Food Science and Human Nutrition showed that that
some lentils such as soy beans, soy foods, peanut butter, and re-fried beans,
contain high concentrations of oxalate compounds. These oxalate compounds were
responsible for the formation of kidney stones. Therefore, individuals who have
kidney stones should stay away from legumes and lentils.
Risk of Kidney Diseases: Consumption of high levels of protein has other side effects as
well. On an average, the amount of protein needed for our body stands at 0.8
grams per one kilogram of body weight. Excessive protein consumption can
pressurize kidneys in flushing out those excess proteins in the body. In the
long run, that elimination can damage overall kidney function.
Formation of Gas Due to Fermentation: After entering the digestive system, lentils start fermenting
and subsequently release gas. These gases can make matters uncomfortable and therefore,
too much lentil consumption should be avoided unless you don’t mind being a bit
gassy!
