ISSUE 37:
Vegan vs. Omnivorous Diet in a Unique Twins Study
Welcome to the 37th issue of the ABS newsletter! Today we will discuss a recent and very unique study comparing the health impact of a vegan and omnivorous diet. Why is this so interesting; we have had these comparative studies done before. This one is a very special study considering the participants. They were all identical twins. Why is this special and ridiculously helpful for a comparative study design? This is the single best way we have to control for genetic variation, since identical twins have the same genes.
What did this study examine:
22 pairs of twins
8 weeks
LDL cholesterol
Plasma lipid profile
Glucose
Insulin levels
TMAO
body weight
What were the results for Vegan Diet group (compared to Omnivore group):
decrease in mean LDL of 13.9mg/dL
decrease in mean fasting insulin of 2.9 micro IU/mL
decrease in bodyweight of 1.9kg
decrease in median fasting HDL, triglycerides, Vitamin B12, glucose, and TMAO
less diet satisfaction at week 4 and 8
Does this end the debate? Not. So. Fast. These data and cardiometabolic marker improvements make perfect sense when you look deeper at the diet composition.
Key factors:
Caloric Intake (Vegan ~200kcal less than omnivorous group)
Fiber intake (Vegan ~1/3 greater fiber intake)
Saturated Fat Intake (significantly lower in Vegan group; replaced with polyunsaturated)
