Case Study: Ward et al., in 2000, conducted a study to evaluate the changes in homocysteine levels in response to two-fold fluctuations (increases and decreases) in dietary methionine intake in 52 healthy men. Subject's usual diets were assessed and they were divided into a highest methionine intake group and a lowest methionine intake group.

The investigators then fed the highest methionine consumers a diet 80% lower in methionine for a week. Conversely, they fed the lowest-met consumers a diet 100% higher in methionine for a week. B vitamin status was normal in all subjects.

Question: The authors found that homocysteine levels did not change from baseline (before changing the diet) to follow-up (after consuming the experimental diet) in either group.

Based on our class discussions, explain their findings. Be sure to consider regulatory events and molecules in your explanation.
