Aluminum

A metal that gets into food from soil and water, and from some food additives.

In the body: In animal studies, high doses affected the nervous system and reproduction.

The one to watch: Cakes. About 380 g, eaten alone, reaches the weekly limit. The rest stay under it at a serving a day. The one with the least room, Coffee creamer, powder, has about 120 g, eaten alone.

Builds up over time. Agencies set an amount you can take in every week, or every day, for life. A food measured against it shows the grams that reach it.

Reviewed foods that carry it

51 reviewed foods carry it, 51 of them rated by dose. A food counts once, as in the foods list: preparations sharing a page (raw and cooked, canned) count once; one with its own page counts apart. Below, one line for each of 56 preparations. 56 of those lines are rated by dose. 59 measurements in all. A preparation measured more than once gets one line, the measurement the dataset leads with or a stricter one, named beside the food; the others fold under it.

Grams to the limit

Grams of each food that reach the limit in its window, for a 70 kg adult. Fewest first: those are the foods to watch.

Known background: an average adult already takes in 0.2–1.5 mg/kg body weight/week. Where the dataset allows, the grams below are the room left after that intake (the median of the surveys’ averages where EFSA gives one, otherwise the highest); beside each, the same limit counted from zero, the food eaten alone.

    How it’s rated

    No cap: this is the upper end of an approximate range (about 50-600 mg/kg) in a 2005 US abstract, not a mean, and it applies to powdered creamer only. EFSA's tolerable weekly intake for aluminium is 1 mg/kg body weight/week, 70 mg a week for 70 kg. At 600 mg/kg, 117 g of powder a week eaten alone would reach it; at the 50 mg/kg end, 1,400 g. The paper's own packet carries 1.5 mg, so a packet a day (10.5 mg a week) is 15% of the limit and adds 12-50% to the 3-12 mg a day of dietary aluminium it quotes. Abstract only.

    Intake: one 2.0 g serving a day, 70 kg adult · Level in the food: 600 mg/kg (upper end of a reported range (about 50-600 mg/kg))

One 80 g slice is 20.81% of the weekly limit, but a slice a day is 145.7% of it, adding 97.1-728.5% to the adult weekly mean (0.2-1.5 mg/kg body weight/week, 14-105 mg/week). Over most of that range a daily habit reaches or passes the doubling line. One slice is not a toxic dose in itself; the limit is weekly, and the rating looks at a daily habit.

Cooked mussels average 47.00 µg/g (CFIA inspection results, 431 samples; the raw mean of 23.49 doubled for water loss), so about 1,489 g cooked a week, eaten alone, would reach it, and about 3,600 g at the median (19.5 cooked).

    How it’s rated

    The counted figure is 720,000 g a week, about 273 servings a day.

    No cap: EFSA's tolerable weekly intake for aluminium is 1 mg/kg body weight/week (2008), 70 mg a week for 70 kg. Eaten alone, about 715,916 g a week would reach it. A serving a day comes to 0.26 mg a week, 0.37% of it, and adds 0.2-1.8% to the average adult intake of 14-105 mg a week.

    EFSA 2018 · grade A

    How it’s rated

    The counted figure is 1,800,000 g a week, about 1,792 servings a day.

    No cap: EFSA's tolerable weekly intake (TWI) for aluminium is 1 mg/kg body weight/week, 70,000 µg a week for 70 kg. Eaten alone, about 1,756,147 g a week would reach it. A 140 g serving carries 5.58 µg; one daily serving is 0.06% of the daily share of the weekly limit. The Health Canada composite covers grapefruit and oranges together. Background intake is not shown.

    Intake: one 140 g serving a day, 70 kg adult · Level in the food: 39.86 µg/kg (mean (pooled by sample count), n = 17)

    Measured on: Health Canada TDS HH07 Citrus fruit, raw (Oranges and grapefruit), as consumed: 13 composites 2000-2012 mean 35.22 ng/g (3 non-detects) plus 4 composites 1999/2016-2018 under the bilingual label mean 54.94 ng/g (1 non-detects); pooled by sample count. The composite names grapefruit and oranges together; grapefruit alone is not separated.
