Eating a high-protein diet in middle age could increase your risk of diabetes and cancer, according to a study published this week in the journal Cell Metabolism.
But don’t stay away from meat for too long – the same study showed those over 65 need more protein to reduce their mortality risk.
Insulin-like growth factor 1, or IGF-1, is a protein in your body related to growth and development.
Past studies have linked IGF-1 to age-related diseases, including cancer.
Mice and humans with higher levels of IGF-1 often have a higher risk of developing these diseases.
Scientists believe protein intake plays a role in IGF-1 activity.
Eating less protein,studies have shown, can lead to lower levels of IGF-1 in your body.
So theoretically, protein consumption could be directly linked to disease incidence and death.
