Fruit salad: light on its own, heavy once it is dressed

A meta-analysis of 8 randomized trials with 1026 people found that eating about 4.7 oz (133 g) more fruit and vegetables a day, for a mean of 14.7 weeks, left body weight 1.2 lb (0.54 kg) lower than in the low intake arms (95% CI -1.05 to -0.04). The trials mixed fruit with vegetables and varied a lot (I2 73%), and none tested fruit salad as such. UK data list homemade fruit salad at 59 calories, 14.0 g sugars and 24 mg vitamin C per 3.5 oz (100 g), and the fruit mix moves the vitamin C most. A cup of plain fresh fruit salad weighs 5.3 oz (150 g) in US survey data. The dressing is what turns it into a different food. With salad dressing or mayonnaise it reaches 247 calories per 3.5 oz (100 g), about 464 calories in a 188 g cup, and with marshmallows 251 calories per 3.5 oz (100 g).

  Energy 59 calories, carbohydrate 14.3 g, total sugars 14.0 g, protein 0.7 g, water 82.6 g, potassium 155 mg, vitamin C 24 mg per 3.5 oz (100 g)

What a real portion looks like

• A cup of plain fresh fruit salad weighs 5.3 oz (150 g) in US survey data, and an unspecified serving 2.6 oz (75 g). — USDA FNDDS portion weights for fresh fruit salad without citrus and without dressing (code 63311000) Evidence E source
  1 cup 150 g; quantity not specified 75 g

  With salad dressing or mayonnaise 247 calories and 9.93 g sugars per 100 g (1 cup 188 g = 464.4 calories); with marshmallows 251 calories and 12.72 g sugars per 100 g (1 cup 171 g = 429.2 calories)

What cooking and storage change

• FDA treats a packaged fruit salad of cut melons as fresh-cut produce, which it defines as a processed food. — ready-to-eat fresh-cut produce sold in the US Evidence E source

What it does to your health

• A meta-analysis of 8 RCTs with 1026 people found body weight 1.2 lb (0.54 kg) lower in high fruit and vegetable arms than in low intake arms. — 8 randomized trials, 1026 participants, mean 14.7 weeks, 133 g more fruit and vegetables a day on average (n = 1026) Evidence A source
  Body weight -1.2 lb (95% CI -2.3 to -0.09; I2 73%; metric: -0.54 kg, -1.05 to -0.04); energy intake +368 kJ (-27 to 762), not significant
• In a randomized crossover study of 9 women, fruit salad eaten as a mid-morning snack gave the best satiety control until lunch. — 9 healthy women, 11 test sessions (n = 9) Evidence B source

Safety, limits and interactions

• At a Wisconsin wedding, fruit salad was the likely vehicle of a norovirus outbreak, with a risk ratio of 3.2 for illness. — 56 of 106 wedding attendees interviewed, 23 ill, May 2015 (n = 56) Evidence C source
  Risk ratio 3.2 (95% CI 1.1-8.3); norovirus GII.4 found in 12 leftover fruit salad samples and a food handler
• Listeria monocytogenes was found in 0.51% of 4691 packaged fresh-cut fruit samples at Canadian retail. — 10,070 pre-packaged ready-to-eat fresh-cut samples at Canadian retail, 2012-2016, 4691 of them fruit (n = 4691) Evidence C source
  L. monocytogenes in 0.51% (0.34-0.76) of fresh-cut fruit; Salmonella, E. coli O157:H7 not detected; melons and apples more often contaminated
• In an Austrian rehab clinic outbreak of Bacillus cereus, eating the fruit salad was linked with a 50% higher risk of falling ill. — 362 residents of a rehabilitation clinic, 29% fell sick, 2013 (n = 362) Evidence C source
  Fruit salad RR 1.50 (95% CI 1.09-2.00); other dishes also implicated
• For fruit salad ingredients, FDA advises scrubbing firm produce such as melons with a clean produce brush, buying pre-cut produce such as half a watermelon only if refrigerated or surrounded by ice, refrigerating all pre-cut or packaged produce, and storing perishable fruit at 40°F or below. — general public Evidence E source
  Scrub melon rind with produce brush, refrigerate pre-cut produce, store at 40°F or below

What people believe that the data does not support

• A review of 11 RCTs and 6 cohorts linked whole fruit with less long-term weight gain and fruit juice with weight gain. — healthy adults in 11 RCTs and 6 prospective cohorts, 1997-2014 (n = 17 studies) Evidence C source
  Whole fruit linked to reduced long-term weight gain; fruit juice to weight gain; no pooled estimate

Who this works differently for

• Poppy seeds are used in fruit salads, and most reported cases of poppy seed allergy are in children. — case reports of poppy seed allergy reviewed Evidence C source
  Anaphylaxis even with traces; cross-reactivity with sesame, buckwheat, nuts, kiwi
• For fruit salad that contains melon, CDC Listeria advice says to avoid cut melon left out for more than 2 hours, or 1 hour above 90°F, and cut melon kept in the refrigerator for more than a week, and to choose melon that has just been cut. CDC lists pregnant women, newborns, people 65 or older and people with a weakened immune system as at higher risk. — general public, higher risk: pregnant women, newborns, people 65 or older, weakened immune system Evidence E source
  Avoid cut melon held over 2 hours at room temperature (1 hour above 90°F) or over a week refrigerated

The bottom line

In a randomized crossover study of 9 healthy women, fruit salad eaten as a mid-morning snack gave the best control of fullness until lunch, compared with eating it at breakfast or drinking apricot juice, and the abstract gives no effect size. A systematic review of 11 trials and 6 cohorts found whole fruit linked with less weight gain over the long term and fruit juice with more, without a pooled estimate. Cut fruit can pick up germs in handling and storage, and the records below show it can make people ill. At a 2015 Wisconsin wedding, fruit salad was the likely vehicle of a norovirus outbreak (risk ratio 3.2, 95% CI 1.1 to 8.3), with the virus found in leftover salad and in a food handler. It is one outbreak, so it shows a handling risk without telling how often this happens. In an Austrian rehabilitation clinic, eating the fruit salad went with a 50% higher risk of falling sick in a Bacillus cereus outbreak (RR 1.50, 95% CI 1.09 to 2.00), though other dishes were implicated too and the strain was isolated from other foods. Canadian retail testing of packaged products found Listeria monocytogenes in 0.51% of 4691 fresh-cut fruit samples (95% CI 0.34 to 0.76), with melons and apples more often contaminated. The FDA classes a packaged fruit salad of cut melons as fresh-cut produce, a processed food. Poppy seeds added to fruit salad can cause fast, life-threatening allergy even in traces, according to case reports that are mostly in children and give no frequency. CDC lists pregnant women, newborns, people 65 or older and people with a weakened immune system as at higher risk from Listeria. For a salad with melon, its advice is to avoid cut melon left out for more than 2 hours, or 1 hour above 90 F, and cut melon kept in the refrigerator for more than a week. CDC also advises choosing melon that has just been cut. FDA advises scrubbing melons with a clean produce brush, buying pre-cut produce only if it is refrigerated or surrounded by ice, refrigerating all pre-cut produce and storing perishable fruit at 40 F or below. We hold no card on fruit salad with medicines, and that gap is not a reassurance.
