Research Spotlight: Replacing dietary sugar

  • A meta-analysis of 38 randomized controlled trials (RCTs) assessed the impact of replacing dietary sugar with other carbohydrates on metabolic health.
  • Over 1300 subjects were involved, and the dietary changes lasted at least one week.
  • Replacing sucrose with starch was found to reduce levels of LDL cholesterol and fasting glucose.
  • Substituting fructose with starch also resulted in decreased LDL cholesterol, while switching fructose for glucose lowered insulin resistance (HOMA-IR) and uric acid levels.
  • No significant changes were observed in triglycerides, HbA1c, CRP, ALT, or AST.
  • A separate study noted that very high fructose intake (150g/day for 8 weeks) didn't adversely affect metabolic health in young, healthy individuals with a normal BMI.
  • Research suggests that while significant sugar reduction may benefit cholesterol and glucose levels, complete elimination is not necessary for everyone, especially if they are active and maintain a balanced diet.

Specificity: Conceptually Simple, but Deceptively Complex

Specificity is a given. All trainers learn the “SAID” principle and know that the body produces Specific Adaptations to Imposed Demands. So, if you want to get stronger, you lift heavy. Thus, in a simple, individual, closed-sport like powerlifting, it’s no surprise that highly specific training is c…
