Blood Glucose Response Chart
Brazil nuts have a low Glycemic Index (GI) of 15 and a low Glycemic Load (GL) of 0.64 (per 100g serving).
Their low GI and GL means that consuming Brazil nuts has a minimal impact on blood sugar levels, making them a suitable choice for individuals managing blood glucose levels, including those with diabetes.
These giant seeds from the capsule of the Brazil nut tree (Bertholletia excelsa) are not only nutrient-dense but also metabolized in a way that supports stable energy release.
The glycemic impact (how much it makes your blood sugar rise) of brazil nuts can be attributed their macronutrient composition and metabolic processing.
Brazil Nuts: Nutritional Composition and Blood Sugar Regulation
Brazil nuts are one of the most nutrient-dense nuts, offering a rich source of healthy fats, proteins, and essential micronutrients. They contain approximately 66% fat, 14% protein, and only 12% digestible carbohydrates, ensuring a slow release of glucose into the bloodstream.
Additionally, Brazil nuts are packed with dietary fiber (~7.5%), further regulating glucose absorption and maintaining stable blood sugar levels.
Brazil nuts is also the richest natural source of selenium. Selenium is a powerful antioxidant that supports glucose metabolism. Magnesium, another key micronutrient in Brazil nuts, plays a significant role in enhancing insulin sensitivity, helping to prevent blood sugar fluctuations.
The combined effects of fiber, fat, and micronutrients make Brazil nuts a valuable food for metabolic health.
Brazil Nuts and Glycemic Absorption
Brazil nuts exhibit a low digestible carbohydrate density, meaning there is limited glucose available for immediate release into the bloodstream. The fiber-rich composition of Brazil nuts slows down enzymatic digestion, reducing the rate of glucose absorption and preventing spikes in blood sugar.
Brazil Nuts and Glycemic Response to Digestion
Unlike high-carbohydrate foods, Brazil nuts contain minimal starch, which significantly reduces α-amylase activity—an enzyme responsible for starch breakdown. As a result, glucose is released gradually, leading to a slow hydrolysis process that helps regulate postprandial blood sugar levels.
This slow digestion and absorption make Brazil nuts an ideal food for individuals focusing on glycemic control.
Brazil Nuts’ Impact on Glycemic Index and Glycemic Load
Brazil nuts has Glycemic Index of 15, classifying them as a low-GI food. Their minimal digestible carbohydrate content and slow glucose absorption prevent significant blood sugar elevation, ensuring metabolic stability.
The Glycemic Load (GL) provides a more accurate measure of blood sugar impact by accounting for portion size:
A 28g serving of Brazil nuts contains approximately 1.19g of total digestible carbohydrates, resulting in an exceptionally low GL score of 0.18 . A 100g serving of Brazil nuts yields a Glycemic Load of 0.64, due to its 4.24g of net carbohydrates.
This confirms that Brazil nuts are a glycemic-friendly snack suitable for blood sugar management.
Brazil Nuts and Their Role in Blood Sugar Stability
Brazil nuts help stabilize blood sugar levels, reduce the risk of insulin spikes, and enhance satiety due to their high-fat and fiber content. The presence of selenium, magnesium, and polyphenols further supports glucose metabolism and insulin function, making Brazil nuts an ideal food for metabolic balance.
Selenium, a potent antioxidant found in high concentrations in Brazil nuts, reduces oxidative stress linked to insulin resistance. Additionally, the high-fat and protein content in Brazil nuts prolong satiety and prevent overeating, making them a beneficial choice for individuals managing diabetes, pre-diabetes, and general blood sugar concerns.
Summary
Brazil nuts are low-glycemic food, with a Glycemic Index (GI) of 15 and a Glycemic Load (GL) of 0.64 per 100g, making them ideal for glycemic control.
Their nutrient-rich composition - including healthy fats, dietary fiber, and key micronutrients - ensures stable blood sugar levels and long-term metabolic health.
Regular consumption of Brazil nuts can help regulate blood sugar, improve insulin sensitivity, and promote sustained energy release.
However, due to their high selenium content, moderation is essential to prevent excessive intake.
As a powerful, nutrient-dense snack, Brazil nuts support long-term metabolic wellness and blood sugar stability.
