As healthy living becomes a priority in Thailand, protein shakes, grilled chicken, and high-protein snacks fill supermarket shelves. Yet new research urges caution about excess protein intake, especially from animal sources. Experts warn that more protein is not always better and emphasize nuanced guidance for different ages and lifestyles.

Protein remains essential for muscle maintenance and many body functions. However, consuming too much—particularly from red meat, eggs, and dairy—can raise insulin-like growth factor 1 (IGF-1), a hormone linked to cell growth. Elevated IGF-1 has been associated with accelerated aging and heightened risk for several conditions, including certain cancers, Type 2 diabetes, and heart disease. For many adults, the potential downsides may outweigh short-term fitness gains.

As Thais become increasingly health-conscious—and protein shakes, grilled chicken, and high-protein snacks dominate supermarket aisles—a new wave of research suggests that excess protein consumption may carry more dangers than benefits, contradicting popular trends and social media advice. Recent findings, highlighted by comments from longevity and nutrition experts, warn against overeating protein, especially from animal sources, and offer nuanced advice on the healthiest intake for different age groups (nypost.com).

The latest scientific insights indicate that while protein is crucial for muscle maintenance and basic biological functions, too much of it—particularly from red meat, eggs, and dairy—can significantly elevate levels of insulin-like growth factor 1 (IGF-1), a hormone involved in cell growth and metabolism regulation. According to the chief executive of an international nutrition company, chronically elevated IGF-1 has been linked to accelerated aging and increased risk of serious diseases, including various cancers, Type 2 diabetes, and cardiovascular conditions. For adults, the risks outweigh the short-term muscle gains often encouraged by fitness culture.
