Starch is the main type of carbohydrate consumed by humans and is a crucial source of energy. Starchy foods include potatoes, pasta, rice, grains, legumes, and root vegetables. They are also a source of fibre, vitamins, and minerals. While starchy foods are an important part of a balanced diet, they can cause blood sugar spikes, especially in people with diabetes or high blood sugar. Therefore, it is recommended to substitute refined starches with whole-grain options, which release sugar into the blood more slowly.

What You'll Learn
Starch is a good source of energy
Starchy foods are an important part of a balanced diet. They are a suitable source of energy because of their high carbohydrate content. When a person's body digests starch, it breaks down into glucose molecules, which enter the bloodstream and power nearly every cell in the body, including the organs, muscles, and brain. The body can use this glucose right away or store it in the liver and muscles for later use.
Starchy foods are also a good source of nutrients such as fibre, calcium, iron, and B vitamins. Fibre can help keep your bowels healthy and can help you feel full, reducing the likelihood of overeating. Starchy foods are also low in fat and good value for money.
However, it is important to note that starchy foods can cause a spike in blood sugar levels, which may be a concern for people with diabetes or high blood sugar. Additionally, simple carbohydrates found in starchy foods like potatoes and pasta are broken down into glucose quickly, which can lead to increased hunger and weight gain. It is recommended to substitute white or refined starches for their whole-grain counterparts whenever possible as they release sugar into the blood slower and are associated with better health outcomes.

Starch is a carbohydrate
Starch is a complex carbohydrate and a natural component of many plants, such as fruits, vegetables, and grains. Starchy foods form an essential part of a healthy diet. When people hear the word “starch,” they may think of foods rich in carbs, such as potatoes, rice, and pasta. However, most plants store energy as starch, including fruits and vegetables.
Starchy foods are the primary source of carbohydrates for most people. They play a crucial role in a nutritious, well-balanced diet, as they provide the body with glucose, which is the main energy source for every cell. They also provide a range of vitamins, minerals, fiber, and other nutrients. Foods rich in starch are valuable ingredients in the kitchen, too, as they can thicken soups and sauces without adding fat.
Starchy foods are sometimes called ‘carbs’. Starchy foods are an important source of fibre as well as vitamins and minerals. Starchy foods are not fattening if consumed in the right portion sizes. It is important not to eat more calories than one needs from any food group. Types of starchy foods include bread, pasta, and rice. It is healthiest to opt for wholegrain versions of these foods.
Starchy foods are a suitable source of energy because of their high carbohydrate content. When a person’s body digests starch, it breaks down into glucose molecules. This glucose enters the bloodstream and powers nearly every cell in the body, including the organs, muscles, and brain. The body can use this glucose right away or store it in the liver for later use. It is particularly important for brain function and the brain requires a lot of glucose.

Starchy foods are a source of fibre
Starch is the main type of carbohydrate that people eat and is a primary source of energy. Starchy foods are an important part of a balanced diet, providing energy, fibre, and various vitamins and minerals. Starchy foods are a suitable source of energy because of their high carbohydrate content. When a person’s body digests starch, it breaks down into glucose molecules, which enter the bloodstream and power nearly every cell in the body, including the organs, muscles, and brain.
Starchy foods come in many forms, and people often consume them as staple foods in diets worldwide. Legumes, grains, and root vegetables are all examples of starchy foods. Starchy foods, including fruits and vegetables, also provide fibre, which is important for digestive health. Fibre that cannot be digested helps other food and waste products move through the gut. Fibre can help keep your bowels healthy and can help you feel full, which means you are less likely to overeat.
Some examples of starchy foods that are a good source of fibre include:
- Wholegrain bread
- Wholewheat pasta
- Brown rice
- Potato skins
- Corn
- Whole-grain pasta
It is recommended that we consume at least 25 grams of fibre per day, from beans and pulses, whole grains, fruits, and vegetables.

Starchy foods are a source of vitamins and minerals
Starchy foods are an important part of a balanced diet, providing the body with energy, fibre, and a range of vitamins and minerals. Starch is the main type of carbohydrate consumed by humans and is a primary source of energy. When starch is digested, it breaks down into glucose molecules, which power nearly every cell in the body, including the brain, organs, and muscles.
Starchy foods include legumes, grains, root vegetables, potatoes, bread, rice, pasta, and cereals. These foods contain fewer calories from fat and are a good source of nutrients such as fibre, calcium, iron, and B vitamins. For example, potatoes are a good source of fibre, B vitamins, and potassium, while also providing some vitamin C. Similarly, whole grains, fruits, and beans are high in fibre, a type of carbohydrate that increases satiety and improves insulin sensitivity.
Whole wheat bread, brown rice, and wholegrain cereals are excellent sources of fibre, iron, B vitamins, and protein. They also provide a slow release of energy and help to keep blood sugar levels stable. In contrast, white bread, white flour, and refined pasta have a higher starch-to-fibre ratio and can cause rapid spikes in blood sugar.
Corn is another starchy staple food that is high in fibre and B vitamins. Oats, another healthy grain option, provide protein, fibre, fat, and a wide range of vitamins and minerals. They have been shown to have health benefits such as lowering blood sugar levels and reducing the risk of heart disease.
In summary, starchy foods are a valuable source of vitamins and minerals, contributing to a balanced and nutritious diet. They provide essential energy and nutrients, but it is important to be mindful of added fats during cooking and serving, as these can increase the calorie content.

Starch can cause blood sugar spikes
Starch is a significant source of carbohydrates and is composed of hundreds of individual glucose molecules. When a person’s body digests starch, it breaks down into glucose molecules, which enter the bloodstream and power nearly every cell in the body.
Starch is one of the largest dietary sources of blood sugar. Even ""healthy" grains such as whole wheat and brown rice convert into sugar during digestion. Simple carbohydrates, such as pasta and potatoes, are quickly broken down into glucose by the body, causing a spike in blood sugar. This is known as the "glycemic load." Whole-grain carbohydrates release sugar into the blood more slowly than refined carbohydrates, resulting in better health outcomes. For example, whole wheat bread has more fiber and less starch than white bread, and brown rice has more fiber and a lower glycemic load than white rice.
Individuals with diabetes or high blood sugar may need to monitor their intake of starchy foods, as they are more sensitive to blood sugar spikes that accompany consuming carbohydrates. Starch-induced glucose spikes can be especially dangerous for people with diabetes, as they can trigger deadly insulin release. However, resistant starch, a non-viscous fermentable fiber, has been shown to enhance glucose metabolism and may even have antidiabetic effects.
To prevent starch-induced glucose spikes, one can reduce starch intake or take a transglucosidase supplement before starchy meals. Transglucosidase is an enzyme that reduces the rapid conversion of starch to sugar and increases the amount of starch that is converted to beneficial fiber in the digestive tract. Studies have shown that transglucosidase can reduce the amount of rapidly digested starch by up to 40%, helping to prevent dangerous spikes in blood sugar following a meal.
