This could seem odd, given what we learn about carbs influencing blood sugar, but it surely does happen in some individuals. This impact is most probably because of the excessive fiber content material and the resistant starch present in beans and legumes.
However, the second meal have an effect on is not an excuse to exit and order an XL bean and rice burrito for lunch daily or eat cups of lentils at each meal. This would do far more harm than good in the long term.

But no matter why there’s a connection between legume consumption and illness prevention, we all know that prevention just isn’t at all times the identical as remedy.
So, what function to lentils play for those that have already got sort 2 diabetes?
Well, there have been combined outcomes about the advantages of consuming legumes for individuals with sort 2 diabetes.
A 2015 research examined the impact of a legume-based intervention food regimen versus a legume-free management food regimen, for a bunch of 31 chubby individuals with sort 2 diabetes. In the legume-based food regimen, two servings of purple meat have been changed with varied cooked legumes, together with lentils, for three days per week. After eight weeks of remedy, they discovered that the legume-based food regimen considerably decreased irritation markers like highly-sensitive C-reactive protein, interleukin-6, and TNF-alpha.
This signifies that lentils might have a constructive impact on total irritation – though the research didn’t handle modifications in blood sugar ranges or A1c.
Another advantage of lentils is that they’ve a glycemic index of 35, which places them squarely into the “low glycemic” class (something beneath 55 is taken into account “low”).
Low GI meals trigger a smaller rise in blood sugar ranges in comparison with larger GI meals do, so lentils could be a better option than, say, potatoes and wheat bread, which have a GI of 78 and 74, respectively.
This sentiment was confirmed in a 2018 research that discovered that lentil-based meals gadgets elicited a a lot smaller post-prandial (submit meal) glucose response than potato-based gadgets did. However, this research was carried out on metabolically wholesome members with regular glucose ranges, not individuals with diabetes.

What does all this boil all the way down to?
Lentils have some clinically vital advantages as a consequence of their fiber content material and potential anti-inflammatory results. However, none of those current research confirmed that consuming lentils result in a big enchancment in blood sugar ranges or A1c.
We additionally know that carbohydrates have the best affect on blood sugar and A1c, and lentils are sometimes fairly excessive in carbs.
