Food Therapy: Lentils (Legumes) Intake in Improvement of Diet Quality

Kyle J. Norton

Intake of lentils frequently and daily may have a substantial and positive effect in improved diet quality, recent recommendation and guidance suggested.

Lentil, a type of pulse or tiny legumes that can be cooked quickly and rich in protein and fiber is a bushy annual plant of genus Lens to the Fabaceae family, native to Middle East.

The differentiation of lentils in improvement of diet quality may be observed through several different aspects and implications.

According to the review of published medical literature online of MEDLINE, EMBASE, CINAHL, and the Cochrane Library for relevant controlled trials of >or=7 days, dietary non-oil-seed pulses (chickpeas, beans, peas, lentils, etc.) are a good source of slowly digestible carbohydrate, fibre and vegetable protein and a valuable means of lowering the glycaemic-index (GI) of the diet.

Further examination of the selected trials and studies satisfied the criteria and guideline of 41 trials (39 reports), found that studies using pulses alone (11 trials demonstrated a significant effect in reduced fasting blood glucose (FBG)  and improved insulin levels, in compared to pulses in low-GI diets (19 trials) in lowered glycosylated blood proteins (GP), expressed blood glucose to the red blood cells, observed by HbA(1c)  in measurement of three-month average plasma glucose concentration or fructosamine, in measurement of glucose levels over the previous 2-3 week and pulses in high-fibre diets (11 trials) lowered FBG and GP.

Observation of the  outcomes of the trials and studies obtained indicated a significant effect of pulses in high-fibre diets in reduced risk of over expression of glucose levels in the tested subjects in compared to other 2 groups.

After taking into account of other con founders such as high inter-study quality and unexplained outcomes, Dr. Mitchell DC, the lead author said, "Pooled analyses demonstrated that pulses, alone or in low-GI or high-fibre diets, improve markers of longer term glycaemic control in humans, with the extent of the improvements subject to significant inter-study heterogeneity".

According to the recommendation of The US Department of Agriculture's (New) MyPyramid guidelines, in doubling dietary intake for vegetables, particularly, in subgroups of vegetables, including dry beans, peas and lentils.

Even through, dry beans, peas and lentils were found to contain a rich source of nutrients and phytochemicals that have been shown to have beneficial health effects by numbers of respectable institutes and recommended by health advocates, but consumption levels in the United States are quite low. 

The review from the National Health and Nutrition Examination Study (NHANES) found that only 0.9% of adolescents, 2.2% of adult men, and 3.5% of adult women met their dietary guidelines for both fruits and vegetables in compared to the EU-28, with average a third (34.4 %) of the population aged 15 or over did not consume any fruit or vegetables in a day; half (51.4 %) the population ate daily from 1 to 4 portions of fruit and vegetables, while the residual 14.1 % consumed more than 5 portions a day.

In the study to assess nutrient and food group intakes of dry bean and pea consumers compared to non consumers using data of dietary intake from the 1999-2002 of National Health and Nutrition Examination Survey for adults aged > or =19 years, researchers surprisingly found that only 7.9% of adults are consuming dry beans and peas everyday. Dry beans or peas intake showed a significant biber, protein, folate, zinc, iron, and magnesium levels and lowering saturated fat and total fat consumption.

Most Mexican Americans or other Hispanics are more likely to be consumers than non consumers.

After in depth differentiation of the data, Dr.Mitchell DC, the lead scientist said, "These data support the specific recommendation for dry beans and peas as part of the overall vegetable recommendation" and "Increased consumption of dry beans and peas-economical and nutrient-rich foods-could improve the diet quality of Americans".

Taken together, there is no doubt that lentil and other dry beans and peas diet may have a substantial effect in improved diet quality to population in all nations.
