As we continue the series on Nutrients from A to Zinc, we now take a look at vitamin E and all its intricacies. Vitamin E may be one of the most complex of the fat soluble vitamins, as eight naturally occurring forms can be found, including four different tocopherols and four similar tocotrienols, each with alpha, beta, gamma and delta types. The most abundant, active and known form is alpha tocopherol, although each compound has its own unique strengths, biological activity and function.
Vitamin E protects vitamin A, carotene, and vitamin C in foods from oxidative destruction. Continue reading “The Antioxidant Power of Vitamin E”
Move over carrots. Although beta carotene (precursor to vitamin A and what gives carrots their orange color) has long been THE nutrient for eye health, a new study shows that vitamin E rich foods lessened the chances of cataracts by just over 25%.
The review published in the Journal Public Health Nutrition looked at 27 studies, including 245,351 individuals from many countries. The researchers looked at vitamin E intake from supplements and diet, combined and alone, and the effect on development of age-related cataracts (ARC). They found a statistically significant decreased risk of developing ARC with increasing dietary vitamin E.
For eye health, and to help improve your eyesight, eat foods like spinach, broccoli, avocados, shellfish, nuts and seeds are all rich sources of vitamin E. If you have trouble meeting your daily dose of vitamin E, a Complete Vitamin E supplement will help fill the gap. Continue reading “Improve Your Eyesight With Vitamin E Rich Foods”
Fertility is not just a women’s issue. Statistics show that 35-40% of infertility issues are male related. So it makes sense to look at how men can improve their chances for conception, as well.
Stress, alcohol and smoking are the most common culprits when dealing with male-related infertility, but there are many other factors that can lower testosterone, decrease sperm concentration, limit motility or even damage sperm, including:
· Prescription medications: talk to your doctor to see if the medications you are taking affect fertility
· Heavy metals, such as lead and mercury
· Hot baths, hot tubs, saunas, steam rooms and laptops Continue reading “Men and Fertility”
A new study in JAMA (Journal of the American Medical Association) found that long-term use of vitamin E increased the risk of prostate cancer. The study showed that a dose of 400 IU vitamin E was not likely to provide benefit for preventing cancer, and in fact found an increased risk for developing prostate cancer. However, when vitamin E was combined with selenium, the risk was reduced even more than with the placebo.
Perhaps this is evidence of the importance of nutrients working together in synergy as opposed to isolating one specific nutrient.
So, should men stop taking vitamin E? Well, this is the first study that has shown a significant link towards cancer. So, talk to your doctor or health care practitioner about what is best for you. If you continue to take vitamin E, choose one that encompasses all aspects of vitamin E as well as the mineral selenium.
Do not disregard the importance of vitamin E in our lives. Deficiencies can result in many issues such as digestive system problems where nutrients are poorly absorbed from the digestive tract. These problems include pancreatic disease, gallbladder disease, liver disease, and celiac disease. Vitamin E deficiency symptoms can also include neuropathy, muscle weakness, slow tissue repair and dry skin and hair. Diet is still the best way to get most nutrients, and luckily vitamin E is readily available in many foods.
A diet rich in foods that contain vitamin E has actually shown to be beneficial in reducing prostate risk. Sunflower seeds, brazil nuts, egg yolks and whole grains are all great dietary sources of vitamin E and can easily help meet your daily vitamin E requirement without supplementation.
According to the University of Texas M.D. Anderson Cancer Center, vitamin E in its natural form, l-alpha-tocopherol, can lower lung cancer risk by 55%!
