When It Comes To Diet, What Really Works?
While some claim a change may alleviate or even eliminate their
psoriasis, current scientific research does not confirm that eating
a certain food or taking a specific supplement clearly makes
psoriasis better or worse. Even the well-known claim that fish oil
works has not been unequivocally proven. Many scientifically valid
studies have been conducted on fish oil, and the results have not
always shown clear improvement.
We also do not have scientific evidence to support the claim that
supplements such as grape seed extract, olive leaf extract, and
Ester C effectively clear psoriasis. The same is true for shark
cartilage, which some say works. If you are considering any food
supplement or herbal remedy, it is important to know that some can
interact negatively with prescription medications. Equally
important, in large quantities, some supplements can be toxic. For
example, large doses of fish oil can be toxic because of the amount
of vitamins A and D that is consumed. Before taking a dietary
supplement or herbal remedy to treat your psoriasis, be sure to
consult a dermatologist. If you are currently supplementing your
diet, tell your dermatologist what kind of supplement or herbal
remedy you are taking and how much you are consuming.
When it comes to diet, dermatologists recommend a healthy balanced
diet. If this balanced diet includes a food that you think makes
your psoriasis worse, conduct your own research. Stop eating the
food, and see what happens. It is possible that some people have
specific food triggers.
Dermatologists also urge patients to avoid any diet that claims it
can “cure” psoriasis. These diets simply do not work, and some are
extreme diets that can be harmful. Fad diets and weight-loss
supplements also should be avoided, especially if you are taking
cyclosporine or methotrexate. If you are overweight, which some
believe makes psoriasis worse, be sure to talk with your
dermatologist if you want to lose weight. A doctor who is familiar
with your medical history is the best person to recommend an
