Heart & Brain Health
How do blueberries protect the heart?
Living on a diet that includes a cup of blueberries daily can lower bad LDL cholesterol and raise good HDL cholesterol. The fiber slows sugar absorption, while potassium helps balance sodium, reducing blood-pressure spikes. A 2021 review found that people who ate berries three times a week had a 15% lower risk of heart disease. If you're also managing blood sugar or exploring timing of meals, combining berry-rich snacks with an intermittent fasting guide can help some people structure berry intake around fasting windows for steady energy.
