Tomato nutrition, glycemic index, calories, and serving size
Tomato Glycemic index (GI)
Vegetables in general contain very little carbohydrates, so they tend to be classified as low glycemic index foods. On average a GI value of 40 could be assigned for most vegetables.
The International Tables of Glycemic Index does not include GI values of vegetables, due to the difficulty of consuming a portion of the food containing 10g of carbohydrates.
However there are GI numbers for other products made from tomatoes. Tomato soup from Canada has a glycemic index of 38±9. Condensed tomato soup, prepared with water, from the US has a GI of 52±4.
Tomato juice with low sodium from Canada has a GI of 23±6. The GI of a tomato juice with no added sugar from the USA is 33±3. Australian canned tomato juice, with no added sugar, has a GI of 38±4. The mean of these three studies makes the glycemic index of a tomato juice 31.
Based on the numbers by The Journal of Ethnic Foods, Nigerian tomatoes have a glycemic index of 38.38±1.42.
According to another study (6) the GI of a tomato ranges around 23±11.
The American Journal of Clinical Nutrition has shown the GI of tomato pasta sauce to be 31.
Consuming 200g of raw tomatoes a day has been studied to have beneficial effects in lowering the risk of cardiovascular diseases, by decreasing blood pressure, in people with type 2 diabetes (7).
Tomatoes are rich with a carotene called lycopene. Although there is no evidence for the association between the intake of lycopene in tomatoes and the risk for having diabetes, the compound may have a beneficial effect on the oxidative stress in diabetic patients (8).
One research has found that while tomatoes do not improve insulin resistance, they are still favorable for diabetic conditions, since they decrease diabetic-induced oxidative stress, inflammation, atherosclerosis and tissue damage (9).
