As we move into 2025, science, technology, and lifestyle awareness are transforming the way we approach food. People everywhere are beginning to wonder: “How can I weave more vibrant, healthy years into the span of my life?” rather than simply, “How can I live longer?” Below are the leading nutrition trends for 2025 that support both longevity and vibrant health.
