Diabetic patients can eat tomatoes, note that diabetic patients can eat raw tomatoes, and at the same time to control the amount, each time to eat tomatoes of medium size a can, do not eat too much at once. Because tomatoes can also have an impact on blood sugar, as long as the amount consumed does not exceed the prescribed amount, it can have a relatively small impact on blood sugar. It is best not to add too much oil, otherwise the heat contained in the tomato dish may increase, which may have a negative impact on blood sugar. Finally, diabetic patients should only be able to add tomatoes as a meal between two meals if their blood sugar is particularly well controlled. If the usual blood sugar is very high, it is not recommended that patients eat additional tomatoes.
