Both starch and glucose occur naturally in carbohydrates, an essential macronutrient. Starches are a form of carbohydrates, while glucose molecules are part of the molecular structure of starchy foods. Both starch and glucose are important elements of a healthy diet. Understanding what foods contain them can help you ensure you're consuming these dietary necessities.
Starch
According to an article published on the National Health Service website, starches are the most common form of carbohydrates in your diet. Starch is found in many common foods. Grains, rice and potatoes are the most common starchy foods. White rice and potatoes contain the highest amounts of starch per serving, with roughly 40 g per 200 calories. The starch content of grains varies, with whole grains such as wheat flour and bulgur containing less starch than white flour or potato flour.
Glucose
Glucose is a type of natural sugar. Glucose molecules are found in all starchy foods. When you eat a food high in glucose, the glucose is absorbed into your bloodstream and stored as energy. According to Mayoclinic.com, the glucose amount in a food can be measured with the glycemic index, which assigns a number to each food based on its glucose content relative to pure glucose. Typically, the higher in starch a food is, the higher that food is on the glycemic index. Potatoes and white rice are high-glucose foods, whereas vegetables and whole grains are lower-glycemic foods.
Significance
Starchy foods are an excellent dietary source of energy and essential nutrients. Many foods high in starch also contain fiber, iron, calcium and vitamins. Carbohydrates high in fiber are often lower in starch and glucose, such as brown rice, couscous and whole wheat. Eating these foods on a daily basis may help you regulate your body weight and can promote healthy digestion. Foods high in starch and glucose provide you with nutritional energy and vitamin B.
Considerations
The consumption of carbohydrates can be associated with weight gain. Instead of avoiding carbohydrates altogether, focus on eating carbohydrates high in fiber and low in starch and glucose. If you have a dietary medical condition such as diabetes or celiac disease, you should consult your health care professional about consuming foods with starch and glucose.
