Myth: Switching out sugar in your diet for carbs will improve cholesterol and blood pressure levels.
Truth: This is false. After conducting a large review study, which was published in the American Journal of Clinical Nutrition, researchers determined that the substitution of sugars for carbs in the diet will not help to improve blood pressure or body weight; the impact on cholesterol remained unclear. Researchers conducted a review of 28 different clinical studies, which involved a total of 510 participants, in order to see the impact of this diet change.
With the switch from sugars to carbs, researchers saw that there was no significant improvement in high-density lipoprotein (good) cholesterol, low-density lipoprotein (bad) cholesterol, or triacylglycerols (the main component of fats). This has large implications for many metabolic diseases, including diabetes, which can develop or worsen as a result of high blood pressure, increased body weight, and/or high cholesterol levels.
