Pomegranates are making a big splash in nutrition research, with scientists in the U.S., Portugal, Israel, India and other nations searching for the latest health benefits of this antioxidant-rich fruit.
Once an exotic item rarely seen in the supermarket, the popularity of ruby red pomegranate juice has made it easy to get the pleasure and benefits of this sweet fruit.
The enthusiasm for pomegranates stems from the high concentration of antioxidants that accompanies the sweetness of its juice.
Pomegranate Heart Health Benefits
One active area of research has looked at the potential heart health benefits of the pomegranate.
These studies indicate that daily consumption of pomegranate juice, about 8 ounces a day for three months or more, can help:
- Reduce dangerous LDL-cholesterol in blood
- Improve blood flow to the heart in patients with coronary artery disease
- Reduce thickening of the arteries that supply blood to the brain
- Lower the level of systolic blood pressure

Laboratory studies have demonstrated that pomegranate juice can help maintain the health of blood vessels by several interacting mechanisms:
1) Reversing a process called LDL-oxidation. LDL, which stands for low-density lipoprotein, is the major protein responsible for transporting cholesterol in your blood and depositing cholesterol in the walls of blood vessels. The level of oxidized LDL in blood is emerging as a leading risk factor for cardiovascular disease.
2) Decreasing inflammation in the lining of blood vessels. Inflammatory cells called macrophages, found in the walls of your arteries, accumulate cholesterol and deposit it in the vessel wall, initiating a process called atherosclerosis, a major step in hardening of the arteries. Pomegranate juice prevents this type of inflammation and inhibits atherosclerosis.
3) Raising the levels of nitric oxide, a chemical that keeps your arteries supple and flexible. Many types of stress impair your blood vessels’ ability to make nitric oxide. Pomegranate juice can prevent both reasons for reduced nitric oxide: impaired synthesis and rapid breakdown.

Research on Pomegranates and Cancer
Research is looking at the ways pomegranate juice and extracts of pomegranates may be able to help fight cancer.
The anticancer effects of pomegranate juice are related to its potential ability to induce cancer cells to self-destruct, a process called apoptosis. Laboratory research studies suggest that pomegranate juice may help induce apoptosis of human breast, prostate and colon cancer cells by activating genes and enzymes that regulate apoptosis.
Pomegranates Fight Inflammation
Whenever it’s been studied, unsweetened pomegranate juice has been more effective than any single component.
Not only does pomegranate juice contain potent phenolic antioxidants, like other brightly colored fruits, but pomegranate juice contains unique complex sugars that are anti-inflammatory on their own.
Here is a delicious recipe featuring pomegranate juice that my son Jonathan Galland wrote for The Fat Resistance Diet.
Omega Blast Granola
Granola is a crunchy and satisfying comfort food. This recipe has a smart mix of whole grain oats, fruit and nuts, and is high in Omega 3’s.
3 Cups Rolled Oats
1 Cup Oat Bran
1/2 Cup Chopped Walnuts
1/4 Cup Freshly Ground Flaxseeds
3/4 Cup Pomegranate Juice
2 Teaspoons Walnut Oil or Olive Oil
1 Teaspoon Cinnamon
1 Teaspoon Vanilla
1 Cup Raisins
Preheat the oven to 325°F. In a big bowl, mix everything except the raisins. Spread the mixture over a nonstick baking pan and bake for 20 minutes, or until nice and brown, stirring occasionally to cook evenly.
Remove from the oven and toss in the raisins. Let cool and put in a glass container for storage in the refrigerator. Makes about 5 cups. Serve one cup granola with one cup nonfat plain yogurt, nonfat milk, or unsweetened soy milk per person.
I hope you enjoy the healthy pleasure of pomegranate juice throughout the year.
