Is it OK for diabetics to eat tomatoes? Tomato and Diabetes

Although classified as a vegetable, tomato is technically a fruit. It’s red flesh forms the basis of gravy in many Indian curries. Can tomato and diabetes survive together? What do you think?

“Knowledge is knowing that tomato is a fruit,

Wisdom is not putting it in a fruit salad!”

Glycemic index and Glycemic load (tomato and diabetes)

Tomato is one of the lowest GI food items and even the carbohydrate is just at the 1% of recommended daily intake. The glycemic load of 100g ripe tomatoes is 15*3.9/100 = 0.6 which is damn good for a type 2 diabetic. 

Thus, eating tomatoes as a part of gravy or mixed vegetable salad won’t affect your glycemic status. Green thumbs up to tomato and diabetes.



Vitamin C 21% of RDA | An experimental study suggests that vitamin C supplementation of 1000mg per day for 6 weeks can cause reduction in blood sugar and lipid levels along with insulin. However, the supplemental dose is almost 17 times the RDA, but increasing the dietary vitamin C intake can help reduce the supplemental dose. Also, as you can see, vitamin C will also help to prevent dyslipidemia which is commonly seen among diabetics.

Vitamin A 17% of RDA | The role of vitamin A in type 2 diabetes is still under review. However, there are 3 possible mechanisms by which vitamin A can be beneficial. These include its antioxidant property, its property to lower insulin resistance and thirdly, it ability to mediate insulin release.

Vitamin K 10% of RDA | Vitamin K (specifically K2) has been scientifically proved to improve the insulin sensitivity through three of its attributes namely the protein osteocalcin, it’s anti-inflammatory effects and the lipid-lowering properties. (R)

Potassium 7% of RDA | Potassium itself has no role to play directly on diabetes parameters. However, diabetics who have kidney disease need to regulate potassium intake to avoid too much or too less of potassium in the body.

Manganese 6% of RDA | A scientific study shows that manganese has some role to play in maintaining blood glucose balance and even the function of kidneys. However, the mechanism behind this is yet unknown. (R)
