Pears: a mild fruit with two specific cautions

The pear is one of the least argued about fruits, and the trials behind it are small. The best of them gave 40 adults with metabolic syndrome two medium fresh pears a day for 12 weeks. Pulse pressure fell from 54 to 51 mmHg. Systolic pressure, the reading the researchers were actually testing, only tended to fall and did not reach significance. That was whole fruit, which matters more here than usual, because the sharpest pear finding we have was measured in juice. Give a child of about one to five an age sized serving of pear juice and 84 percent of them leave the carbohydrate incompletely absorbed, against 41 percent after apple juice and about 20 percent after grape. Six children in that study got diarrhoea. The five year olds in the same trial showed no difference between the juices, so the result sits with the younger ones. The fibre that comes with a whole pear is absent from the juice, so the result describes the drink and cannot be carried over to the fruit in your hand.

The numbers, per 100 g

What your body absorbs

• One age sized serving of pear juice left carbohydrate incompletely absorbed in 84% of children aged about 1 to 5, against 41% after apple juice and about 20% after grape juice, with no difference between the juices in the 5 year olds. — 104 healthy children in three age groups, about 1, 3 and 5 years old, one randomly assigned juice each, breath hydrogen measured for 3 hours (n = 104) Evidence B source
  Incomplete absorption (breath hydrogen peak above 20 ppm) in 84% after pear juice vs 41% apple, 20% white grape, 24% purple grape, p < 0.05; diarrhoea reported in 6 children after pear juice

What it does to your health

• Two medium fresh pears a day for 12 weeks lowered pulse pressure from 54 to 51 mmHg in 40 adults aged 45 to 65 with metabolic syndrome, while systolic pressure only tended to fall. — 40 men and women aged 45 to 65 with metabolic syndrome, 12 week treatment periods separated by a 4 week washout (n = 40) Evidence B source
  Pulse pressure 51 ± 1 vs 54 ± 1 mmHg at baseline, P < 0.05; systolic 130 ± 2 vs 134 ± 2 mmHg, P = 0.07
• Pooling four cohort studies, each extra 100 g a day of apples or pears went with 5% lower risk of developing hypertension. — four cohort studies inside a meta-analysis of 18 prospective studies, 451291 participants and 145492 hypertension cases (n = 451291 in the full review) Evidence C source
  Summary RR 0.95 per 100 g/day, 95% CI 0.93 to 0.98, I2 = 0%
• Twenty male cyclists riding 75 km finished 3.3% faster while eating pears than on water alone, a gap that did not reach statistical significance. — 20 male athletes cycling 75 km, taking water, bananas or pears at 0.6 g carbohydrate per kg per hour in randomised order (n = 20) Evidence B source
  3.3% faster with pears, P = 0.091; bananas 5.0% faster, P = 0.018; both fruits halved the postexercise rise in lipid metabolites
• In 341519 European adults followed for a median 13.4 years, the top quartile of apple and pear, banana, mushroom and onion intake carried 42% lower risk of Crohn disease, with a confidence interval that reached 1.02. — 341519 participants of the EPIC cohort, 149 cases of Crohn disease and 379 of ulcerative colitis over a median 13.4 years (n = 341519) Evidence C source
  Fourth vs first quartile adjusted HR 0.58, 95% CI 0.33 to 1.02, P trend 0.03; no association with ulcerative colitis

Safety, limits and interactions

• Among 15 birch pollen allergic adults with a history of pear allergy, 14 of 15 reacted to Conference pears and 12 of 15 to Cepuna pears in blinded oral challenges. — 15 adults from an allergy clinic, average age 37, all sensitised to one or both pear varieties, challenged outside the birch pollen season (n = 15) Evidence B source
  12 of 15 symptomatic on Cepuna, 14 of 15 on Conference

What people believe that the data does not support

• In 61 people with type 2 diabetes the glycaemic index of pears measured 60, and it did not differ statistically from seven other common fruits tested the same way. — 61 patients with type 2 diabetes, randomised into eight groups, one fruit per group (n = 61) Evidence B source
  Glycaemic index 60 ± 4.9 for pears against 63 for apples and 83 for bananas, with no statistically significant difference between fruits

Who this works differently for

• The cultivar changes how hard the reaction is: objective symptoms appeared in 2 of 15 challenges with Cepuna pears against 7 of 15 with Conference pears. — the same 15 birch pollen allergic adults, each challenged with both varieties (n = 15) Evidence B source
  Objective symptoms 2 vs 7 of 15; the difference did not reach significance in a group this small

The bottom line

Eat pears because you like them. Nothing on this page turns them into a treatment. The blood pressure signal beyond that one small trial is thin and borrowed. Pooling four cohort studies, each extra 100 g a day of apples or pears went with 5 percent lower risk of developing hypertension, and apples and pears are counted together in those cohorts, so nobody can say which fruit carried it. The gut finding has the same problem. In 341519 European adults followed for a median 13.4 years, the top quartile of apple and pear, banana, mushroom and onion intake carried 42 percent lower risk of Crohn disease, with a confidence interval that reached 1.02, which means the data is still compatible with no effect. Four foods pooled into one number, observational to begin with. One common belief about pears was tested directly. They are sold as the gentle fruit for blood sugar, and in 61 people with type 2 diabetes the glycaemic index of pears came out at 60, next to 63 for apples and 83 for bananas, with no statistically significant difference between any of the eight fruits tried. Eight small groups of people can hide a real gap, so the honest reading is that no difference was found, not that pears have been shown to be equal. Two cautions on this page are real, and both are narrow. The first is pear juice for small children, the finding above, which is a reason to give a one to three year old water or a whole pear rather than a glass of juice. The second is allergy. Among 15 adults allergic to birch pollen who already knew they reacted to pear, blinded challenges brought on symptoms in 14 of 15 with Conference pears and 12 of 15 with Cepuna. The variety changed how hard the reaction was: objective symptoms appeared in 7 of 15 challenges with Conference against 2 of 15 with Cepuna, and in a group of fifteen that gap did not reach significance. Everyone in it came from an allergy clinic, so these are not rates for the general population. If your mouth itches after apples or birch pollen season is hard for you, this is a fruit to raise with a doctor instead of testing on yourself. The holes are worth naming, because most of the safety picture here is missing rather than reassuring. Our drug interaction layer is indexed by nutrient, so for a whole fruit it comes back empty by construction. That is a limit of our method and says nothing about whether pears interact with medicines. We found no trial of what cooking or storing does to a pear, and the USDA retention tables carry no factors for its fibre or carbohydrate at all. Neither the United States nor the European register holds an authorised health claim naming pear. The fruit is also less consistent than a single table row suggests: across six Foundation samples of raw bartlett, insoluble fibre ran from 1.7 to 3.7 g per 100 g against a listed 2.8, and no study explains the spread. One more result stayed unproven rather than negative. Twenty male cyclists riding 75 km finished 3.3 percent faster eating pears than on water alone, and that gap did not reach significance, while bananas in the same trial did.
