Macro partitioning

Substituting Polyunsaturated Fatty Acids (PUFA) for carbohydrates (LGI or HGI) significantly reduces the odds of developing hypertension.

To potentially lower your risk of developing hypertension, consider replacing 3% of your daily calories from carbohydrates (both low and high glycemic index) with Polyunsaturated Fats (PUFA). This is particularly beneficial for women in this study. Ensure you keep your total calorie intake the same by reducing carbs rather than adding extra fat. Good sources of PUFA include fatty fish, walnuts, and sunflower oil.
