Food logging / recovery / antioxidants

Fuel the work.
Do not chase an antioxidant score.

MacroFactor is the best fit for photo-plus-text logging and controlling the speed of weight change. Cronometer is better when deep micronutrient coverage matters. Neither can produce a scientifically valid total antioxidant-intake score.

01FOOD LOGGING

Use the camera as a draft.

Photo estimation is convenient but portion size is its hardest problem. Add a text description, ingredients, and weights for calorie-dense foods to turn a rough guess into useful data.

Best overall fit$71.99/year

MacroFactor

Its AI food logger accepts a meal photo plus text. More importantly, it adapts calorie targets using your logged intake and observed weight trend.

  • Photo and natural-language entry
  • Garmin weight via Apple Health or Health Connect
  • Clear smoothed trend and change-rate target
Deep nutrients299.99 zł/year

Cronometer Gold

Better for inspecting vitamins, minerals, amino acids, and fatty acids. Photo and voice logging reduce friction, while curated database entries can be more complete.

  • Tracks more than 95 nutrients
  • Photo logging and voice entry
  • Best for adequacy and deficiency checks
Accuracy limitHuman review

Photo alone

A camera cannot see cooking oil, hidden ingredients, recipe ratios, or exact mass. Treat its answer as editable structured input, not a laboratory estimate.

  • Name sauces and oils in text
  • Weigh staple portions while learning
  • Save repeat meals and recipes
02ANTIOXIDANT EVIDENCE

No proven recovery shortcut.

Intensive apnea creates oxidative stress, but that does not prove that more antioxidant supplements improve recovery. The stress signal may be part of the adaptation.

Deep dives increase oxidative markers

Recent repeated-dive research reported increases in reactive oxygen species and inflammatory markers. This establishes physiological stress, not a supplement benefit.

Static apnea also activates defenses

After maximal static apnea, antioxidant enzymes increased while malondialdehyde did not. That pattern is consistent with a rapid endogenous defense response.

The direct supplement evidence is tiny

A crossover trial gave seven people 1 gram of vitamin C daily for seven days. Some biomarkers changed, but it did not show faster recovery or improved freediving performance.

Megadoses can have a cost

A randomized endurance-training trial found that high-dose vitamins C and E blunted some cellular adaptations even when performance changes were less clear.

03PRACTICAL RECOVERY

Track adequacy, not ORAC.

There is no validated human score that turns a day of food into total antioxidant protection. ORAC measures test-tube chemistry, not biological effect, and the USDA withdrew its consumer database.

Food first

Build variety over the week

Log fruit, vegetables, legumes, nuts, seeds, whole grains, herbs, spices, cocoa, tea, and coffee as foods. Cronometer can show vitamin and mineral adequacy, but color and variety are the more honest proxy for plant compounds.

Priority order

Recover from the actual load

Adequate energy and carbohydrate, sufficient protein, hydration, sleep, and sensible progression have much stronger practical justification than chasing a large supplement dose.

Supplement rule: correct a demonstrated deficiency or follow medical advice. Avoid routine megadoses of isolated antioxidants around key adaptation sessions without a clear reason.
Freediving safety: never perform in-water breath-hold training alone and do not hyperventilate. A favorable HRV, sleep, or readiness score does not make maximal apnea safe.
