CLINICAL
UPDATE - Antioxidant therapy alleviates severe psoriasis
58
patients with severe psoriasis were hospitalized and treated with either
a placebo or a mixture of CoQ10, vitamin E and selenium. Supplementation
significantly improved clinical symptoms while simultaneously lowering
markers of oxidative stress.

E, and selenium supplementation to psoriasis patients.
CLINICAL
UPDATE - Zn, Ca and Mg reduce type 2 diabetes risk
One
study followed more than 82,000 nurses ages 33-60 years for 24 years
and found higher zinc intake was associated with a slightly lower risk
of type 2 diabetes. Another study followed more than 64,000 Chinese
women and found that higher calcium and magnesium intake protected against
the development of type 2 diabetes.

CLINICAL
UPDATE - Does Lp(a) promote tumor growth?
Researchers
measured Lp(a) levels on 418 men with lung cancer and found they had
significantly higher levels of Lp(a) than healthy controls, supporting
the claim that Lp(a) plays an important role in the development of tumors

state in male patients with primary lung cancer
CLINICAL
UPDATE - Vitamin C helps prevent gout
Nearly
47,000 men were followed for 20 years and showed that a higher vitamin
C intake, which has been shown in previous trials to reduce uric acid
levels, significantly lowered the risk of gout.

CLINICAL
UPDATE - Can vitamin D lower rates of infection?
Since
recent studies have suggested a role of vitamin D in immunity, a group
of researchers looked at the association of vitamin D levels and upper
respiratory tract infections (URTI) in nearly 19,000 people and found
vitamin D levels to be independently associated with URTI, especially
in people with asthma and chronic respiratory diseases.

CLINICAL
UPDATE - Glutamine maintains intestinal barrier
Glutamine
deficiency has long been associated with increased gut permeability
and recent work reveals the specific mechanism of how glutamine protects
the intestinal barrier.
