Avocado diets improve blood sugar and heart health outcomes

Recent research suggests that regular avocado consumption may lower the risk for type 2 diabetes and reduce cardiometabolic risk factors. Separate studies have indicated that eating avocados daily can help improve the body's blood sugar response and contribute to better heart health.

One study found that women who consumed 30 to 38 grams of avocado per day had a lower risk of developing diabetes compared to those who did not. The same significant association was not observed in male participants. Researchers suggested this difference could be due to lifestyle factors, such as a higher rate of smoking among the men in the study, or potential hormonal differences between sexes.

Improved Blood Sugar Control

A separate six-month study published in Current Developments in Nutrition examined the effects of daily avocado intake on 961 adults with elevated waist circumference, a risk factor for type 2 diabetes. Participants were divided into two groups: one continued their usual diet, while the other was instructed to eat one large avocado daily without other specific dietary restrictions.

After six months, the group that consumed an avocado each day showed a significant reduction in their dietary glycemic load (GL). GL measures how the quality and quantity of carbohydrates in a diet affect blood sugar. Diets with a lower GL are associated with better glycemic response and a reduced risk of type 2 diabetes and other cardiometabolic conditions like obesity, insulin resistance, and hypertension.

According to nutrition experts, avocados can help lower dietary GL by replacing foods with higher carbohydrate and sugar content. The fruit's fiber and unsaturated fat content also slow digestion, which helps to prevent sharp spikes in blood sugar after meals and can increase feelings of fullness.

Heart Health Benefits Linked to Fruit Pairing

Another study focused on individuals with prediabetes found that combining avocado with mango could yield cardiovascular benefits. In the eight-week trial, participants who ate one avocado and one cup of mango daily showed improvements in heart and vascular function.

The group consuming the fruit combination demonstrated better flow-mediated dilation (FMD), a measure of blood vessel health. Male participants in this group also experienced a notable reduction in diastolic blood pressure. While experts acknowledged the findings were promising, they also pointed to the study's limitations, including its relatively small size and short duration.
