Mango: which mango, and how much of it

Vitamin C in mango runs from 17 to 212 mg per 100 g across eight USDA Foundation samples, and the British tables give 26 mg where the American give 168. That is a twelvefold spread inside one food, and the review that explains it names variety, season, and handling before and after harvest without sizing any of them. So a mango number is a starting point. The amount also decides the direction of at least one result. Postmenopausal women eating 85 g of Ataulfo mango a day for 16 weeks had fewer deep wrinkles, and women eating 250 g of the same fruit had more wrinkles on four separate measures. That was a pilot with no placebo, no stated blinding and many outcomes tested twice, which is the setting where a p value near 0.05 turns up on its own. Take the reversal as the finding rather than either half of it, and note that the authors themselves recommend 85 g for any follow-up study.

The numbers, per 100 g

How much is actually in it

• The amount of vitamin C in a mango depends on which mango, and the review that says so does not say by how much. — published literature on mango pulp, peel and seed Evidence D source
  Pulp and peel are named as sources of ascorbate, soluble and insoluble fibre and phenolic compounds including gallic and protocatechuic acids, and the authors state that variety, seasonality, pre and post-harvest handling, extraction of bioactives and physiological barriers all modify the nutraceutical potential
• An eight week trial fed two named mango varieties to people with type 2 diabetes and both groups lost weight against bread. — 35 people with type 2 diabetes, Safeda n=10, Dasheri n=10, bread control n=15 (n = 35) Evidence B source
  Against bread, Safeda lowered fasting blood glucose by 26.9 mg/dL (p = 0.005) and HbA1c by 0.9% (p < 0.001), Dasheri lowered fasting glucose by 36.1 mg/dL (p < 0.001) and HbA1c by 0.5% (p < 0.02); weight fell 2.4 kg with Safeda and 2.1 kg with Dasheri, and total skinfold thickness fell 17.7 mm and 20 mm respectively

What your body absorbs

• Tracking mango polyphenols through the body showed that the marker researchers rely on does not come only from food. — ileostomists and subjects with a full gastrointestinal tract (n = number not stated in the abstract) Evidence C source
  89 phenolic catabolites appeared in urine and 26 in plasma, arising by at least four routes: absorption in the upper gut, microbial breakdown in the lower bowel, origins independent of mango intake through breakdown of the body's own proteins, and combinations of these; the authors conclude that raised hippuric acid is not an appropriate biomarker of polyphenol intake

What cooking and storage change

• Blended whole, mango and berries produced a lower glycaemic index than the same fruit eaten in pieces. — adults with obesity and healthy weight adults (n = number not stated in the abstract) Evidence C source
  In participants with obesity the glycaemic index fell from 44.85 ± 20.18 to 25.43 ± 18.20 for raspberry with mango (p = 0.034) and from 42.56 ± 20.64 to 26.30 ± 25.72 for passion fruit with mango (p = 0.044), with similar results in healthy weight participants

What it does to your health

• Three hundred grams of mango a day beat the same amount of fibre for constipation, in a pilot whose abstract gives neither the number of participants nor the size of the effect. — healthy volunteers with chronic constipation, described by the authors as a pilot study (n = pilot, number not stated in the abstract) Evidence B source
  Mango significantly improved stool frequency, consistency and shape, raised gastrin and faecal valeric acid, and lowered plasma endotoxin and interleukin 6, all beyond the equivalent fibre arm

Safety, limits and interactions

• One patient had anaphylaxis to mango eaten before exercise while her blood IgE test stayed negative, and in that same patient the skin test was positive to fresh mango and negative to canned. — one 21-year-old woman with atopic dermatitis, allergic rhinitis and mild asthma (n = 1) Evidence D source
  Skin prick testing was positive to fresh mango pulp at 5 mm against a 3 mm histamine control and negative to pineapple and to canned mango at 3 mm; serum specific IgE to mango was undetectable; both reactions followed mango eaten before exercise, and she tolerated mango without exercise and exercise without mango between episodes
• Mango led the fruit list for cadmium, and the same review calculated the risk from eating fruit as below the threshold. — published measurements of arsenic, lead, cadmium, copper, nickel and iron in fresh and processed fruits worldwide Evidence B source
  The highest concentrations of arsenic, cadmium and lead were found in pineapple, mango and cherry respectively; the highest and lowest copper were in plum and banana; the total target hazard quotient in infants stayed below 1 and the review concludes that eating fresh and processed fruit is safe

What people believe that the data does not support

• Mango added to a sugary breakfast did not raise the glucose peak, and the same carbohydrate as table sugar did. — 18 healthy young adults (n = 18) Evidence B source
  The glucose spike was higher with added sucrose than control (p = 0.007) while mango did not differ from control; the glucose area under the curve was higher than control for both sucrose and mango (p < 0.02); satiety was rated higher with mango at 15, 30, 60 and 120 minutes (p < 0.05), and snack calories did not differ between arms

What is still unknown

• Eighty five grams of mango a day reduced wrinkles and two hundred fifty grams made them worse. — healthy postmenopausal women with Fitzpatrick skin type II or III (n = pilot, number not stated in the abstract) Evidence B source
  Deep wrinkle severity fell in the 85 g group at 8 weeks (p = 0.007) and 16 weeks (p = 0.03); the 250 g group showed increases at 16 weeks in average wrinkle severity (p = 0.049), average wrinkle length (p = 0.007), fine wrinkle severity (p = 0.02) and emerging wrinkle severity (p = 0.02); cheek erythema rose in the 85 g group (p = 0.04)

The bottom line

Mango does something odd and useful to a sugary breakfast. Eighteen healthy young adults ate cornflakes plain, with 34 g of added sucrose, or with mango supplying 38 g of carbohydrate. The sucrose raised the glucose spike and the mango did not. The total area under the glucose curve rose with both, so the sugar still arrived, more slowly. People felt fuller with mango and then ate exactly as much at the snack two hours later. Eighteen healthy young people and one meal, and nobody with diabetes was tested. Blending it whole lowered the glycaemic index rather than raising it. Mango with raspberry came out at 25.43 against 44.85 for the same fruit eaten in pieces, and mango with passion fruit at 26.30 against 42.56, in adults with obesity. The fibre stays in, which is what makes this different from juicing. The standard deviations are as large as the means, and mango was never tested by itself, always mixed with a seeded fruit. For constipation, 300 g of mango a day beat an equal amount of fibre over four weeks on stool frequency, consistency and shape. The comparator is the strength of that design, because matching the fibre means the difference cannot be the fibre. The authors call it a pilot, and the abstract gives neither the number of participants nor any effect size, which is a real limit and not a quibble. Inflammatory markers moved in the same small study and should be read as a lead. Some of the enthusiasm about mango polyphenols has just lost its main piece of evidence. Feeding mango puree to people with and without a colon produced 89 phenolic breakdown products in urine, arriving by at least four routes, and one of those routes is the body breaking down its own proteins regardless of what was eaten. The authors conclude that raised hippuric acid is not an appropriate marker of polyphenol intake. Any claim that mango polyphenols reach the blood in a useful amount now has to get past that. Two practical notes. Mango carried the highest cadmium of the fruits in one pooled review, and the same review calculated the risk from eating fruit as below the threshold of concern, including for infants. Cadmium in a plant comes from the soil it grew in, so that league table is largely a league table of growing regions. And one young woman had anaphylaxis after eating mango shortly before exercise. Her blood IgE test to mango came back undetectable, which is the part worth carrying: a normal blood allergy test does not rule this out. The reaction needed exercise as a cofactor, and she ate mango safely on days without it. In that same patient the skin test was positive to fresh mango at 5 mm and negative to canned mango at 3 mm, and 3 mm is what the histamine control measured in the same test. One patient, one skin prick, and no basis for anyone else to decide that canned mango is safe for them.
