Title: 10 NUTRITION MYTHS
DESCRIPTION:
In this session, Dr. Harcombe will unveil 10 common nutrition myths, providing evidence-based insights that will revolutionize your understanding of food and health.
10 Common Nutrition Myths:
Meat and Saturated Fat Myths
Dairy has more saturated fat than other whole food groups.
All fat-containing foods have a mix of saturated, unsaturated, and polyunsaturated fats.
Red Meat Misconceptions
No Randomized Control Trial (RCT) evidence against red meat; all negative associations lack causation.

Dietary Fat Fallacy
No concrete evidence from RCTs or association studies supporting the restriction of dietary fat.
Limited studies involving only men with heart disease, and no calls for guideline changes.

Cholesterol Clarified
Misunderstanding between dietary cholesterol and heart disease; dietary cholesterol doesn't significantly impact blood cholesterol.
Cholesterol is vital for bodily functions and repair.
Discrepancies in the 1956 7-country study.
Research in 2010 indicates an inverse relationship between cholesterol levels and mortality.

Saturated Fat and Heart Disease
Saturated fat doesn't directly cause heart disease; the level of intake and its impact are inversely related.

Fiber Insights - do you need 25-30g a day?
Fiber is an indigestible polysaccharide; no proven necessity for gut health.
No RCTs supporting the benefits of fiber, but successful RCTs for people with IBS after fiber removal.

"Eat 5 a Day" Myths
Originated in 1991, no scientific basis or studies supporting this claim.

"Eat Less, Move More" Reality
Eating less can lead to increased consumption later, and less activity; the body compensates.

Public Health and Influence
Public health decisions are not always aligned with our best interests; often influenced by companies and financial interests.
