Author/Year/CountryStudy designObjectiveParticipantsHealth statusInterventionMain results
Tenore et al. [28], 2017, ItalyRandomized, single-blind, clinical trialTo evaluate the effects of daily consumption of Annurca apple for 8 weeks on plasma TC, LDL-c and HDL-c in healthy, mildly hypercholesterolemic human subjects.

  • Adults

  • Men and women

  • 18 years to 83 years

  • n = 250

Healthy and slightly elevated cholesterol

  • Protocol: 1 apple a day

  • Duration: 8 weeks

  • ↓ TC and LDL-c

  • ↑ HDL-c and TG

Chai et al. [27], 2012, United States of AmericaRandomized, controlled, unblinded clinical trialTo evaluate the effect of dried apple versus dried plum consumption on reducing CVD risk factors in postmenopausal women.

  • Adults

  • Women

  • 50 years to 55 years

  • n = 160

Postmenopausal

  • Protocol: 75 g/day of dried apple

  • Duration: 12 months

  • ↓ TC and LDL-c

  • ↑ HDL-c and ↓ TG

Koutsos et al. [25], 2020, United KingdomRandomized, controlled, crossover clinical trialTo determine the effects of apple consumption on circulating lipids, vascular function and other CVD risk markers.

  • Adults

  • Men and women

  • 29 years to 69 years

  • n = 43

Mild hypercholesterolemia

  • Protocol: 2 apples a day

  • Duration: 8 weeks

  • ↓ Serum cholesterol and LDL-c

  • ↓ TG

  • There were no differences in concentration of HDL-c

Vafa et al. [29], 2011, IranRandomized, controlled cinical trialTo verify the effect of Golden Delicious apple on the lipid profile in hyperlipidemic and overweight men.

  • Adults

  • Men

  • 18 years to 41 years

  • n = 46

Hyperlipidemic and overweight

  • Protocol: 300 g of Golden Delicious apple a day

  • Duration: 8 weeks

  • Apple consumption did not change lipid profile in overweight men

Ravn-Haren et al. [26], 2013, DenmarkRandomized, single-blind, crossover clinical trialTo investigate the effect of the consumption of whole apples and processed apple fractions for four weeks on plasma lipids, bile acid excretion, blood pressure and other CVD risk factors.

  • Adults

  • Men and women

  • 18 years to 69 years

  • n = 23

Healthy individuals

  • Protocol: 550 g of fresh apple a day

  • Duration: 4 weeks

  • ↓ TC

  • There was no difference in LDL-c concentration between the placebo group and the apple group

↓: decrease; ↑: increase
