Why this matters
Think through the nutrition questions before cutting methionine or protein.
How the pieces connect
Protein helps meet several needs. Ask how any proposed dietary change would affect nutrition before acting on a homocysteine number.
Changing a food changes more than one pathway
The argument in this discussion is that restricting a nutrient to alter one marker can affect other needs at the same time. Foods containing methionine also contribute protein and other nutrients. An experimental restricted diet, a specialist diet for an inherited disorder and an ordinary balanced diet are different situations. Read this discussion’s criticism of restriction within the population it addresses, rather than using it to overturn a medically prescribed nutrition plan.
Keep in mind
Do not restrict protein on your own to change a homocysteine number. If a specialist prescribed a diet for a rare inherited condition, follow that team’s instructions.
A question for your next conversation
What is the purpose of the proposed diet, and how will nutritional adequacy be assessed?
BUILD YOUR UNDERSTANDING
A few concepts, made clearer.
L-Methionine
An amino acid used in protein synthesis and other metabolic processes.
Read the full referenceMTHFR
Makes an enzyme that helps produce a form of folate used in the processing of homocysteine. Common variants are different from rare variants that cause severe MTHFR deficiency.
