Mayo Clinic says :

• Low GI: Green vegetables, most fruits, raw carrots, kidney beans, chickpeas, lentils and bran breakfast cereals
• Medium GI: Sweet corn, bananas, raw pineapple, raisins, oat breakfast cereals, and multigrain, oat bran or rye bread
• High GI: White rice, white bread and potatoes

There are plenty of healthy and nutritious foods to choose from. You should base your diet on the following low-GI foods:

• Bread: Whole grain, multigrain, rye and sourdough varieties
• Breakfast cereals: Porridge made with rolled oats, bircher muesli and All-Bran
• Fruit: Such as apples, strawberries, apricots, peaches, plums, pears and kiwi
• Vegetables: Such as carrots, broccoli, cauliflower, celery, tomatoes and zucchini
• Starchy vegetables: Carisma and Nicola potato varieties, sweet potatoes with an orange flesh, corn, yams
• Legumes: Examples include lentils, chickpeas, baked beans, butter beans, kidney beans

• Rice: Basmati, Doongara, long-grain and brown rice
• Grains: Quinoa, barley, pearl couscous, buckwheat, freekeh, semolina
• Dairy: Milk, cheese, yogurt, custard, soy milk, almond milk

The following foods contain few or no carbohydrates and therefore do not have a GI value. These foods can be included as part of a low-GI diet:

• Meat: Including beef, chicken, pork, lamb and eggs
• Fish and seafood: Examples include salmon, trout, tuna, sardines and prawns
• Nuts: Such as almonds, cashews, pistachios, walnuts and macadamia nuts
• Fats and oils: Including olive oil, rice bran oil, butter and margarine
• Herbs and spices: Such as salt, pepper, garlic, basil and dill

Foods to Avoid on a Low-GI Diet

Nothing is strictly banned on the low-GI diet.

However, try to replace these high-GI foods with low-GI alternatives as much as possible.

• Bread: White bread, Turkish bread, bagels, naan bread, French baguettes, Lebanese bread
• Breakfast cereals: Instant oats, Rice Krispies, Corn Flakes, Cocoa Krispies, Froot Loops
• Starchy vegetables: Désirée and Red Pontiac potatoes, instant mashed potatoes

• Cakes and biscuits: Scones, doughnuts, cupcakes, cookies, waffles, pikelets
• Extras: Jelly beans, licorice, Gatorade, Lucozade

SUMMARY:To follow a low-GI diet, limit your intake of the high-GI foods listed above and replace them with low-GI alternatives.

Drawbacks of the Low-GI Diet

Although the low-GI diet has several benefits, it also has a number of drawbacks.

Firstly, the glycemic index (GI) does not provide a complete nutritional picture. It's important to also consider the fat, protein, sugar and fibercontents of a food, regardless of its GI.

For example, the GI of French fries is 75, whereas a baked potato, the healthier substitute, has a higher GI of 85 (3Trusted Source).

In fact, there are many unhealthy low-GI foods, such as ice cream (GI 36–62), chocolate (GI 49) and custard (GI 29–43).

Another drawback is that the GI measures the effect of a single food on blood sugar levels. However, most foods are consumed as part of a larger mixed meal, making the GI difficult to predict in these circumstances (28Trusted Source).

Lastly, as mentioned earlier, the GI does not take into account the number of carbs you eat. However, this is an important factor in determining their impact on your blood sugar levels.

For example, watermelon has a high GI of 80 and therefore would not be considered the best option when following a low-GI diet.

However, watermelon also has a low carbohydrate content, containing only 6 grams of carbs per 100 grams. In fact, a typical serving of watermelon has a low glycemic load (GL) of 5 and a minimal effect on blood sugar levels.

This highlights that using GI in isolation may not always be the best predictor of blood sugar levels. It's important to also consider the carb content and GL of a food.

SUMMARY:The low-GI diet has a number of drawbacks. The GI can be difficult to calculate, it does not always reflect the healthiness of a food and it doesn't take into account the number of carbs consumed.
