Bs for Stress and Energy

B-complex supplement products are popular commodities, often marketed for “stress” or “energy.” Is there scientific justification for these claims? Why should anyone choose a B-complex supplement as opposed to either broader multivitamin-mineral supplements or narrower single B-vitamin supplements? You might remember in the early ‘90s when a neuropathy epidemic broke out in Cuba among unsuspectingContinue reading “Bs for Stress and Energy”

Vitamin E

Vitamin E refers to eight compounds (vitamers: tocopherols and tocotrienols) and is found in both plants and animal foods (1). The most studied natural source of vitamin E is alpha-tocopherol because of its prevention of lipoprotein oxidation and inhibition of platelet aggregation, which suggests prevention of cardiovascular disease (1). Alpha-tocopherol is the only one withContinue reading “Vitamin E”

Antioxidants – Comparing Apples to Oranges

Which will keep the doctor way? The orange contains about 10 times more vitamin C, which is an essential antioxidant for many complex roles in the human body (1). On the other hand, the apple contains quercetin, which has been shown to have a higher antioxidant capacity than vitamin C, thus, potentially offering better protectContinue reading “Antioxidants – Comparing Apples to Oranges”

Whether or Not to Take Vitamin C

Unlike most other mammals, humans and other primates don’t synthesize vitamin C because we lack the enzyme glunolactone oxidase (1). The enzyme was lost long ago without affecting our survival due to frequent intake of high-vitamin C fruits and vegetables. Thus, we must continue to get vitamin C from our diet by the same mannerContinue reading “Whether or Not to Take Vitamin C”

Review of study on using antioxidant response as predictor for radiation pneumonitis

A currently unpredictable outcome of radiotherapy on lung cancer patients is radiation pneumonitis (lung inflammation). This study was the first performed on humans to determine how antioxidant response may be used to predict this “potentially lethal treatment-related complication”. The oxidative stress link had been established through studies on irradiated mice. Type of study: Observational studyContinue reading “Review of study on using antioxidant response as predictor for radiation pneumonitis”

Fatty acids and Depression

Sailor Man Should Not Be Without His Olive Omega-3 fatty acids from fish have largely stolen the spotlight for anti-depression, but recent evidence finds that oleic acid from olive oil may also be useful in women. Last May a 10-year national cohort followed 1,947 men and 2,909 women (African-American and Caucasian) (1). They were separatedContinue reading “Fatty acids and Depression”

Omega Ratio Rationale?

The plethora of scientific studies on lipids and nutrition would have nutritionists thinking within reason that omega-3s are the chosen fatty acid to deliver humankind from sickness. But despite the seemingly omnipotent oil’s overabundance of qualities, not nearly enough is known about how much to consume in relation to other fatty acids such as omega-6.Continue reading “Omega Ratio Rationale?”

Fiber for IBS, which is best?

Patients with irritable bowel syndrome (IBS) could find great relief from using dietary fiber, but how can clinicians make sure they get the right fiber? A 2004 systemic review published in Ailment Pharmacol Ther improved means of advising patients with IBS on which fiber to take. The review included 17 randomized, controlled trials on bothContinue reading “Fiber for IBS, which is best?”

Is Metabolic Syndrome for real or just a popular clinical tool?

Cardiovascular disease and diabetes have several inter-related risk factors that may include obesity, high-cholesterol, high-triglycerides, hypertension, insulin resistance and inflammation (1). All these separate conditions can be treated in various ways. But why not lump them all together: metabolic syndrome? Combining the cluster of risk factors into one condition remains controversial among scientists. On oneContinue reading “Is Metabolic Syndrome for real or just a popular clinical tool?”
