Score your meal.
Find out how your food affects longevity. Scored 0-10 on 30+ nutrients and longevity research.
How the longevity score works
Every meal you enter is broken down into its ingredients by AI, and each ingredient is matched against a database of nearly 1,000 foods rated on longevity research — from large cohort studies on mortality to trials on inflammation, cardiovascular health, and cellular aging. Ingredients that research consistently links to longer, healthier lives (fatty fish, leafy greens, legumes, olive oil, fermented foods) score positive. Ingredients linked to accelerated aging (processed meat, deep-fried food, added sugar) score negative.
Each ingredient's effect is weighted by how much of the meal it makes up — a slice of bacon in a big salad moves the needle less than a plate of it. Meals built from several different beneficial ingredients earn a diversity bonus, because variety matters for longevity in its own right. The result lands on a 0–10 scale where 5.0 is neutral: above it, your meal is doing work for you; below it, against you.
What the numbers mean
8.5–10 is an exceptional meal — think wild salmon with quinoa and broccoli, or oatmeal with blueberries and walnuts. 7–8.5 is a genuinely great choice. 5–7 is solid, doing no harm. Below 5, the meal works against you — pepperoni pizza with fries lands here. The “±minutes” estimate translates the score into the currency the research actually uses: epidemiological studies consistently associate dietary patterns with differences in lifespan. It is an honest estimate for intuition, not a medical measurement.
The same scoring model powers the Biohack app, where every logged meal also feeds into daily tracking of 30+ nutrients. You can read the full methodology in how the longevity score works or browse the research behind Biohack.
Frequently asked questions
Is the longevity score scientifically proven?
The score is a heuristic grounded in published nutrition research — cohort studies on mortality, trials on inflammation and cardiovascular health. No single number can capture a food’s full effect on your body, but the direction and magnitude reflect what the research consistently shows.
What do the plus and minus minutes mean?
They translate the score into intuition: large epidemiological studies associate dietary patterns with measurable differences in lifespan. The minutes are an estimate derived from those associations — a way to feel the stakes of a single meal, not a promise or a medical measurement.
Why did my healthy meal not score higher?
The score weighs ingredients by their share of the meal, so one large neutral ingredient (rice, pasta, bread) dilutes a few great ones. Processing matters too — the same vegetable scores differently fried versus steamed. Adding one or two more beneficial ingredients usually lifts the score through the diversity bonus.
Is the meal scorer free?
Yes — free, no signup, no credit card. It is the same scoring engine the Biohack app uses; the app adds daily nutrient tracking, AI coaching, and a fasting timer on top.
Which meals score highest?
Meals that combine several research-backed ingredients: fatty fish with vegetables and olive oil, legume-based bowls with leafy greens, oatmeal with berries and nuts. Diversity of beneficial ingredients matters as much as any single superfood.
