A Low-GI Food
One serving of tomato will not lead to spikes in blood sugar.
Image Credit: Polka Dot Images/Polka Dot/Getty Images Foods that have a ranking closer to 100 are considered high-GI foods, and foods that have a ranking closer to zero are considered low-GI foods. At less than 15, tomatoes are considered a low-GI food. This means that the tomato is digested and absorbed more slowly than high-GI foods. Eating a tomato will raise blood sugar and insulin levels gradually rather than rapidly. Because of this, the tomato would be an appropriate vegetable to include in a low-GI diet plan, which might be prescribed for someone who has diabetes or difficulty controlling his weight.
