Psidium guajava

Pink guava is a common tropical fruit that is found in many parts of tropical and subtropical countries (including Malaysia). Pink guava is famous for its sweet and musky fragrance that have unique tropical notes of papaya, passion fruit and ripe pear. Many guava fruits are claimed to have a slightly sour taste, but pink guava is known to be the sweetest kind of all guava varieties.

Pink guava is called as “pink” due to its pink colour flesh that carries a phytochemical known as “carotenoid”. Carotenoids are beneficial antioxidants that keep you protected from diseases, aging and enhance your immune system. For its nutritional values, guava fruit is considered as one of the richest sources of vitamin C as it contains at least 3 times that of recommended daily allowance. Besides, guava contains other nutrients like potassium and pectin which can helps to lower blood cholesterol.

HEALTH BENEFITS

High in antioxidant

Randomized crossover design

Subject

Psidium guajava L. and Psidium acutangulum D.C

Parameters analysed

free radical DPPH scavenging
ferric reducing antioxidant power assay (FRAP)

Outcomes

Peel and pulp of guava extracts were tested to have remarkable antioxidant capacity.
There was a significant correlation between estimated extractable phenol content and radical scavenging activity and ferric reducing antioxidant power.
Guava extract inhibited the LDL oxidation in vitro.
Guava could be a promising source of natural antioxidants.

Improves heart health

Randomized and single-blind trial

Subject

Hypertension patients

Duration of the study

12 weeks

Groups

0.5-1.0 kg/day

Dosage

With guava diet (n = 61)
Without guava diet (n = 59)

Parameters analysed

Blood lipid analysis

Outcomes

Significant net decrease of total cholesterol (9.9%), triglycerides (7.7%), and blood pressure (9.0/8.0 mm Hg), with net increase in high-density lipoprotein cholesterol (8%) after 12 weeks of guava fruit consumption.

	Group A (n = 61)		Group B (n = 59)
	At entry mean (SD)	Change after 12 weeks mean (SD)	At entry mean (SD)	Change after 12 weeks mean (SD)
Cholesterol (mg/dL)	226(20)	-26.6	223(18)	-5.6
Triglycerides (mg/dL)	116(18)	-18.6	162(15)	-5.8
High-density lipoprotein (HDL) (mg/day)	44(8)	+2.4	46(11)	-1.2
Blood pressure (mm.Hg) 1) Systolic 2) Diastolic	163(6) / 106(4)	-13.6 / -11.0	161(7)	-4.6 / -3.0

Function

Moderate intake of guava fruit in daily diet provides sufficient amount of dietary fibre, antioxidant vitamins and minerals. -Inclusion of high fibre food can decrease fat intake by decreasing lipoprotein metabolism and blood pressure, which subsequently may improve overall heart health.
