Nutritionists are sharing surprising advice for those dealing with a condition that affects blood sugar control—guidance that might actually stop a serious disease from progressing.
About 96 million adults and roughly 8 million children in the U.S. are facing prediabetes, a precursor to type 2 diabetes. This condition, characterized by elevated blood sugar levels and insulin resistance, often goes unnoticed because it usually doesn’t present any symptoms for years, until it escalates into full diabetes.
Traditionally, doctors have advised individuals with prediabetes to choose foods that lead to a gradual increase in blood sugar, favoring whole foods over processed sugary options. However, recent research suggests that high-sugar fruits could be crucial in reversing prediabetes.
Tropical fruits contain sugars ranging from 10 to 50 grams, which those worried about blood sugar typically try to avoid. Yet, clinical nutrition researcher Raedeh Basiri argues that mangoes, though high in natural sugars, may provide protective benefits for adults with prediabetes. Participants who consumed a mango daily demonstrated improved blood sugar control, increased insulin sensitivity, and reduced body fat.
A mango is packed with essential vitamins—A, C, B6, and E—along with important minerals like potassium and copper, and over five grams of fiber. This fiber is vital as it slows sugar absorption into the bloodstream, helping prevent rapid spikes that could lead to type 2 diabetes, a condition affecting 37 million Americans.
Choosing the right foods involves considering more than just sugar content. Fiber and vitamin levels are equally significant. Basiri states that those at high risk for diabetes should focus not only on sugars but also on how those sugars are delivered in foods.
In Basiri’s long-term clinical trial, notable for its demonstration of the tropical fruit’s positive influence on metabolism and lean body mass despite sugar levels, researchers from Florida, Nevada, and Virginia enlisted 24 adults aged 50 to 70 with prediabetes. They excluded individuals with existing diabetes or specific dietary habits that might affect the study’s outcome.
Participants were randomly divided into two groups for 24 weeks. One group consumed 300 grams of fresh mango daily (about 32 grams of sugar), while the control group ate a granola bar containing about 11 grams of sugar and equivalent calories each day.
At different points throughout the study, including initial assessments and at weeks 6, 12, and 24, researchers measured various health indicators such as blood sugar and insulin levels, insulin sensitivity, and overall body composition.
They tracked participants’ body fat percentage, lean mass, total water weight, and assessed metrics like BMI and waist-to-hip ratio. The data revealed promising evidence supporting the benefits of daily mango intake for those with prediabetes.
The most significant health improvements were seen in the mango group, whose fasting blood glucose levels decreased. In contrast, the control group’s levels increased, resulting in an appreciable 18.3 mg/dL enhancement for the mango eaters by the study’s conclusion. Their fasting blood glucose levels dropped to 107.0 mg/dL compared to the control group’s 125.3 mg/dL, which is outside the normal range of 70 to 99 mg/dL.
Additionally, the long-term blood sugar marker remained stable for the mango group, while it rose in the control group, underscoring the protective effect of daily mango consumption on blood sugar regulation.
Benefits also extended to body composition; those consuming mangoes showed a decent reduction in body fat percentage from about 31% to 29%, along with an increase in fat-free mass, which is crucial for a healthy metabolism as muscle plays a key role in managing blood sugar levels.
On the other hand, the control group did not exhibit significant improvements, suggesting that adding a daily mango could be a viable dietary approach for better metabolic health and body composition in individuals at risk for type 2 diabetes.
The study has been published in the journal Foods. Basiri emphasized that it’s not just about sugar content but rather the overall context of the food consumed.
The aim is to inspire individuals to incorporate whole fruits, like mango, into their diet as part of effective strategies for preventing diabetes.
Preventing prediabetes fundamentally involves establishing sustainable lifestyle habits that enhance insulin use and blood sugar management.
Key strategies may include adopting a balanced diet rich in fiber from fruits, vegetables, and whole grains, while minimizing processed foods and sugary beverages. Maintaining an active lifestyle is also essential; experts recommend aiming for at least 150 minutes of moderate exercise, such as brisk walking, weekly to help muscles utilize glucose more effectively. Additionally, it’s important to keep a healthy weight, get enough sleep, and manage stress to enhance metabolic health and significantly lower the chance of developing type 2 diabetes.
