Yes, lemon is good for diabetes. In fact, lemons are listed as a diabetes superfood by the American Diabetes Association (ADA).

Lemons are an excellent choice for diabetics because they contain high levels of vitamin C and other antioxidants that can help lower blood sugar levels and improve insulin sensitivity.

Glycemic Index of Lemon

Lemon has a glycemic index (GI) of 20, classifying it as a low GI food.

The glycemic index (GI) of a food is a measure of how much a food impacts blood glucose levels. The glycemic index is a measure of how rapidly glucose is absorbed by your body. It is calculated as follows: It's measured on a scale from 0 to 100, with 100 representing pure glucose and 0 representing no glucose. The greater the glycemic index (GI) of a meal, the greater the blood sugar increases. Foods that have a low glycemic index are much better for people living with diabetes to consume. Lemon water for diabetes is miraculous as when ingested with a meal that has a high GI, lemon juice may help to inhibit the conversion of starch to sugar, hence decreasing the GI of the item. Lemon has a very very low glycemic index which makes it great to consume for just about everyone.

When you consume the fruit, you get the nutritional advantages of the fruit's fiber content. It has been shown that soluble fiber may reduce the absorption of sugar into your circulation, which can aid in the stabilization of blood sugar levels. Citrus fruits are high in bioactive (poly)phenolic flavonoids and vitamin C, making them a healthy snack option. Citrus consumption over a longer period of time has been shown to positively regulate the indicators of type 2 diabetes. The majority of epidemiological investigations have produced equivocal results. The direct acute impact of citrus on postprandial glycemic response is rather minimal in comparison to other foods. The gut microbe composition and flavanone bioavailability are both important factors in individual responses.

Citrus fruits are widely eaten around the globe, both in their raw and processed forms, and are particularly popular in juices. However, whereas fruit eating is generally considered to be advantageous to long-term health, the effects of fruit juices are more contentious, and are tied to the high intrinsic sugar content of the liquids themselves. Citrus juices, on the other hand, are rich in numerous nutrients, including vitamin C, and also include a variety of bioactive components, such as (poly)phenols, which are found in the fruits themselves. According to a research conducted in 2013, the bioactive components found in citrus fruits may prove to be beneficial in the prevention and treatment of obesity. People who are overweight or obese are more prone to acquiring diabetes because the body's capacity to appropriately utilise insulin to manage blood sugar levels is put under additional strain. Incorporating citrus in one's daily diet is a must as despite all these benefits, citrus has even more good long term health impacts.

  • Trusted Source discovered that consuming 1,000 milligrams of vitamin C for six weeks may help minimize the risk of type 2 diabetes complications by lowering blood sugar and cholesterol levels, according to the journal Diabetes Care.
