Researchers from University of Otago have found that a natural fruit source of vitamin C – kiwifruit – is vastly superior to a purified supplement form.

The researchers are studying kiwifruit as a source of dietary vitamin C and found that in mice eating kiwifruit, vitamin C uptake was five times as effective as taking a purified supplement form.

The study was recently published in the American Journal of Clinical Nutrition, the highest ranking journal for human nutrition research. ...

Researchers at Yale School of Medicine, Harvard Medical School and the Broad Institute have identified a prime suspect in the mystery of an increased incidence of autoimmune diseases in the past few decades—dietary salt. In the paper, researchers showed that salt can induce and worsen pathogenic immune system responses in mice and that the response is regulated by genes already implicated in a variety of autoimmune diseases.

Surgeons have successfully replaced a patient’s skull with a 3D-printed version. Three months after the operation the patient, a 22-year-old woman with a rare disorder that thickened her skull and gave her poor eyesight as well as headaches, has recovered her eyesight and has gone back to work.

Human trials are now planned. If successful, the simple, cheap HIV vaccine could be taken as a probiotic-like drink.

The new vaccine works in the opposite way to most vaccines - by suppressing, rather than triggering, an immune response. This is because HIV and SIV actually require immune cells known as CD4 T-cells in order to proliferate and establish an infection in the body.

While they are super sweet, syrup made from this ancient fruit has antibacterial compounds that are more effective than honey. In case you've never had it or seen it before, dates are a thick, dark brown, and super-sweet fruit used in Middle Eastern cuisine. New research suggests that date syrup contains chemical compounds that help ward off a number of bacterial infections, including those caused by Staphylococcus aureus and Escherichia coli. This was discovered after scientists inhibited the growth of these pathogens for about six hours, which researchers say is faster than manuka honey - a honey known for its antibacterial and wound healing properties. ...

White bloods cells, known scientifically as leukocytes, are immune system cells that fight infect. The immune system is made up of a network of cells, tissues, and organs that work together to protect the body. Sometimes our bodies encounter pathogens like bacteria, or in this case a parasitic worm. Roundworms, or nematodes, are parasites that can infect people by living and feeding in the intestines. There are different kinds of worms that can cause infection, and they can range in length from 1 millimeter to 1 meter. Luckily, this worm was no challenge for these hungry white blood cells. ...

According to a new study published in Cell Metabolism, mice who spent their free time on a running wheel were better able to shrink tumors (a 50 percent reduction in tumor size) compared to their less active counterparts. Researchers found that the surge of adrenaline ( epinephrine) that comes with a high-intensity workout helped to move cancer-killing immune (NK) cells toward lung, liver, or skin tumors implanted into the mice.

While the research is hopeful for patients looking for inexpensive ways to manage their cancer, more needs to be learned about the effects of exercise on metastasis and longevity, as well as if the observations hold true in humans. Scientists also wants to explore the combined impact of anti-cancer treatments and ex ...

Phytochemicals are compounds in foods found in plants that are thought to be beneficial to health. More than 5000 different types have been identified, and several studies have linked their intake to reduced risk for cardiovascular disease, cancer, diabetes, Alzheimer’s, cataracts, and age-related decline. While they may be beneficial, they are not considered nutrients (substances necessary to sustain life), thus no daily recommended intakes have been established.

A list of five popular phytochemical families are listed below, along with their health claims and food source.

Carotenoids:

Includes: Alpha-carotene, beta-carotene, lutein, lycopene, zeaxanthin, etc.

Health Claims: Diets with foods rich in these phytochemicals may reduce the risk of ...
