High blood pressure? Try a glass of orange juice!

Tuesday, August 15th, 2017

Good news for orange lovers: citrus fruit intake has been associated with reduced stroke risk.

The key may lie with a citrus phytonutrient called hesperidin, which appears to increase blood flow throughout the body, including the brain.

Using a machine known as a doppler fluximeter, scientists can measure blood flow through the skin using a laser beam.

If we hook people up to this machine and give them a solution containing the amount of hesperidin found in two cups of orange juice, blood pressure decreases and overall blood flow increases.

Good news for orange lovers: citrus fruit intake has been associated with reduced stroke risk.

When subjects drank straight orange juice instead of the hesperidin solution, their blood flow was even better. In other words, the stroke-reducing effects of oranges extend beyond just the hesperidin.

When it comes to food, the whole is often greater than the sum of its parts.

The positive effects of citrus fruits on blood flow don’t require a machine to measure them. In one study, scientists recruited women who suffered from sensitivity to cold weather due to poor blood flow — women with chronically cold hands, feet and toes — and placed them in a highly air-conditioned room.

The women in the experimental group drank a solution containing actual citrus phytonutrients, while another (control) group drank a placebo (an artificially flavoured orange drink).

The placebo drinkers got colder and colder. Because of decreased blood flow, the temperature of their fingertips dropped nearly 13c during the course of the study.

The fingertips of the women who drank real citrus, meanwhile, cooled less than half as fast, because their blood flow remained steadier.

The researchers also had both groups of women plunge their hands into icy water and saw the citrus drinkers recover about 50 per cent faster than the control group.

Sip the Health Benefits of Orange Juice for Clearer Arteries

Wednesday, August 2nd, 2017

Whether beside oatmeal or eggs, this breakfast favorite helps prevent hardening of the arteries: orange juice.

The health benefits of orange juice include vitamin C. And in a study of men, those with a high intake of vitamin C—as well as berries and other fresh fruit —experienced significantly less thickening of their carotid arteries compared with the low fruit-and-C group.

Findings published in the American Journal of Clinical Nutrition confirms the presence of a natural plant chemical called hesperidin – part of a a class of disease-fighting compounds found in plant foods like tea, fruit, soya and cocoa.

Although previous studies have hinted orange juice may be good for the heart, scientists have been uncertain exactly what gives it its protective powers, til now.

Pipe-Cleaning C

Clear arteries. They’re super important because gunk-free can often mean problem-free. But carotid-artery thickness is important, too. It’s a direct measure of atherosclerosis—the narrowing and hardening of the arteries that can lead to heart disease, heart attack, or stroke. To keep your arteries wide open and pliable for years to come, you need the health benefits of orange juice and other foods rich in vitamin C and pipe-friendly antioxidants. 

Open Wide

Aside from preventing the hardening of the arteries, similar studies have found that vitamin C may help protect your cardiovascular system in numerous ways as well. Whether you get the health benefits of orange juice or another vitamin-C-rich food, the cells lining your arteries will improve, your risk of blood clots will decrease, and bad-for-your-heart inflammation will fade away.
