The Berry Family (including strawberries, blueberries, raspberries, Blackberries etc.)

Numerous studies have confirmed that consuming berries contributes to the regulation of serum total cholesterol, serum triglycerides, low-density lipoprotein cholesterol, and blood pressure levels. Regular intake of berries can reduce the risk of cardiovascular diseases by 17%.
Dark-colored berries, especially blueberries, are rich in high levels of anthocyanins, which can protect vision, enhance memory, and benefit children's bone development.
Fresh berries have limited storage durability, making frozen berries a preferable alternative.
Research has found that "raspberries frozen and stored for 60 days" retain nutritional values that are not inferior to, and in some cases superior to, "raspberries stored at room temperature for just 2 days."

It is important to note that the freezing duration should not be excessively prolonged. Generally, a period of 12-24 months is considered safe, whereas exceeding 30 months significantly diminishes nutritional value.
Additionally, berries must be consistently maintained in a low-temperature environment. Repeated thawing and refreezing can lead to a sharp decline in nutritional value.
Health Advisory
For elderly individuals with sensitive gastrointestinal systems, it is advisable to avoid consuming frozen fruits directly and to consume them after thawing.
Studies indicate that the majority of antioxidant components in berries, including vitamin C, anthocyanins, and catalase, remain well-preserved even after microwave heating.
