What It Measures in Kaizora
Each food you logged, with its time, amount, and nutrients: energy, protein, carbohydrates, fibre, fats, vitamins, minerals, caffeine, alcohol, water, and more.
- Foods and nutrients
How It Gets to Kaizora
A file import: export your Food & Recipe Entries (servings.csv) from the Cronometer website and import it. Importing again replaces the days it covers.
Strengths
- Tracks far more nutrients than most food diaries.
- Keeps exact definitions, such as vitamin A as retinol activity equivalents, which Kaizora keeps as given.
Limits
- The export is on the website only, not in the mobile app.
- A nutrient Kaizora has no metric for yet is skipped.
About What It Measures
How Much Added Sugar Is Too Much?
The WHO's limit of 10% of energy from free sugars and its 5% ideal, the AHA's 25 g and 36 g a day, how added and free sugars differ from total sugars, and how to find yours.
How Much Saturated Fat Should You Eat?
The WHO's limits of 10% of energy from saturated fat and 1% from trans fat, what that is in grams, what trials found about cutting saturated fat, why replacing it matters, and where the evidence is disputed.
How Much Sodium Should You Eat, and Why Does Potassium Matter Too?
The National Academies' 2,300 mg a day for sodium and the WHO's 2,000 mg, the Adequate Intakes for potassium, how salt and sodium differ, and where most sodium in a diet comes from.
What Are Net Carbs?
How "net carbs" subtract fiber and sometimes sugar alcohols from total carbohydrate, why no US or EU labelling rule defines them, why a European label's carbohydrate already leaves fiber out, and what that means for comparing numbers.
What Do the RDA, AI, and UL Mean?
How the Dietary Reference Intakes set the Estimated Average Requirement, the Recommended Dietary Allowance, the Adequate Intake, and the Tolerable Upper Intake Level, why they're averages over time, and how to read your intake against them.
What Vitamin D Level Is Enough?
Why experts disagree on the level, the National Academies' 20 ng/mL (50 nmol/L), the Endocrine Society's 2024 advice against routine testing, what large trials found, and how much vitamin D the Dietary Reference Intakes recommend.
