Pomegranate, the Wonder Fruit

By Sabeen Faquir, MPH candidate

The pomegranate or punica granatum originates from Persia. It was cultivated over the whole Mediterranean region since ancient times and became naturalized. It is extensively cultivated throughout India and the dry regions of southeast Asia, Malaya, the East Indies and tropical Africa.

You may or may not know this but the pomegranate’s benefits are profound. It can help almost every bodily system (cardiovascular, endocrine, nerve, skeletal and blood system) as well as benefit oral health. One of the first steps in building arterial plaque is damage of macrophages.  Pomegranate’s flavonoids can prevent this damage (Aviram et al).  “Pomegranate polyphenols were shown to reduce the capacity of macrophages to oxidatively modify LDL, due to their interaction with LDL to inhibit its oxidation by scavenging reactive oxygen species and reactive nitrogen species and also due to accumulation of polyphenols in arterial macrophages; hence, the inhibition of macrophage lipid peroxidation and the formation of lipid peroxide-rich macrophages,” (Aviram et al.)

Pomegranate is also known to help lower blood pressure. It does this by lowering angiotensin converting enzyme activity. In a study where subjects drank 50 ml or 1.5mmol of total polyphenols every day for 2 weeks, researchers found a 36% decrease in serum ACE activity and a 5% reduction in systolic blood pressure (Aviram, Dornfeld). In another study, they found a statistically significant increase in urinary free cortisone and a decrease in free cortisol/cortisone ratio after one week of pomegranate juice consumption (Tsang et al). This also helps lower blood pressure.

And because of its chondroprotective effects in mice, pomegranate can theoretically help with osteoarthritis in humans (Mahsa, Reza). In another study where they aimed to measure whether pomegranate and carvacrol (a phenol found in oregano and other herbs) could alleviate oxidative stress on the sciatic nerve, they found the combination decreased the pro-inflammatory response (Celik et al).

In yet another study they found pomegranate’s ability to protect teeth from degeneration. Hydro-alcoholic extract (HAE) from pomegranate decreased the CFU/ml by 84% (Silvna el al). It can also help gingival health by reducing the risk of gingivitis (DiSilvestro et al).
