Some evidence suggests that the high polyphenolic content of dates may benefit your heart health. Polyphenols are micronutrients that naturally occur in plants. The polyphenols in dates help increase your HDL (“good”) cholesterol and reduce your total cholesterol, which are risk factors for heart disease.
A study published in 2020 tested the effects of consuming dates on blood fats and glycemic index. The researchers randomly assigned 100 males and females with type 2 diabetes to eat three dates daily for 16 weeks or no dates at all.
People who ate dates had a statistically significant decline in LDL (“bad”) and total cholesterol. A measure of blood sugar control over the previous two- to three-month period, or HbA1c, did not change.
