Metabolic diets

MSUD diet tracker

Maple syrup urine disease. Also called branched-chain ketoaciduria.

In MSUD the body can’t break down the three branched-chain amino acids: leucine, isoleucine and valine. The diet limits leucine most closely, and many families count isoleucine and valine too, since clinics often add them back.

Phebe counts all three in milligrams, with a daily target for each, so a day’s leucine is as easy to see as a day’s calories.

Your clinic sets your targets. Phebe does the counting.

What Phebe counts

  • leucine
  • isoleucine
  • valine
  • protein

Plus calories, macros, minerals, vitamins and every other amino acid.

How Phebe counts

  • Search the food database, scan a barcode, or photograph a nutrition label.
  • Weigh a portion on a Bluetooth kitchen scale, and the grams go straight into the entry.
  • Set a daily target for each nutrient you count, and see what is left today.
  • Log favorites in one tap, and build a recipe once to log the dish.
  • Start on your phone with no account. A free account adds the web app at app.phebe.life.

MSUD questions

Does Phebe work for MSUD?
Yes. Phebe tracks leucine, isoleucine and valine in milligrams, each against its own daily target, alongside protein and calories.
Can I show only the amino acids I count?
Yes. You choose which nutrients appear, so Today shows the ones your diet counts.
Is Phebe free?
Yes. Phebe is free on iPhone, Android and the web, with no ads and no paywall.
Where do the amino acid numbers come from?
From USDA food analyses, for every food that has been measured. For a packaged food whose label lists only protein, Phebe estimates all 18 amino acids from the label and its ingredients, and shows the range.
