Presenting at the Berry Health Benefits Symposium in Philadelphia earlier this month, a group of international researchers explored how various berries interact with numerous body systems, particularly the microbiome, to confer these benefits.“When we characterize the gut microbial community, we’re really trying to understand who is there and what they are doing,” said Johanna Lampe, PhD, RD, professor at the Public Health Sciences Division at the Fred Hutchinson Cancer Center. “The concentration and bioactivity of berries is actually highest in the gastrointestinal tract.”Berry bioactivity is attributed to polyphenols called anthocyanins, which give fruits and vegetables their red, purple and blue…

Frozen vegetables are a fast, budget-friendly way to add nutrition and color to soups, stews and curries.Their softer texture works best in brothy or saucy dishes, where simmering helps them blend right in.Because most frozen veggies are unseasoned, taste and adjust with herbs, salt or acid to make flavors shine. At thirteen, when my peers were becoming obsessed with playing video games and reveling in music their parents hated, I spent most of my outside-of-school time looking after my little sister and baby brother. Our parents worked long hours from their respective home offices, and I was frequently entrusted with…
