Male Infertility

Recent research suggests that male infertility is a common problem. Researchers have found that the higher quality omega-3 fatty acids EPA and DHA improve the vitality of sperm and improve male fertility. A recent analysis by Hosseini and associates concluded the following: "This meta-analysis indicates that supplementing infertile men with omega-3 fatty acids resulted in a significant improvement in sperm motility and concentration of DHA in seminal plasma."

Another study repeats the emphasis on omega-3 fats but also mentions the apparent importance of cereal grains and fruits and vegetables. These researchers wrote, "Studies have indicated that in men with idiopathic infertility, omega-3 intervention resulted in significant improvement in total sperm count as well as sperm cell density. Moreover, several studies have shown that higher intake of poultry, cereals, fruit and vegetables may play a beneficial role in male infertility." It sure sounds like ProVitality Plus with omega-3 fats, grain, fruit and vegetable extracts along with a good protein supplement might be worthy of attention for those suffering with infertility.

Fruits, Fruit Juice, Soft Drinks

Consumption of 100% fruit juices was associated with increased risk of cancers comparable to the risk associated with sugary soft drinks like regular coke. A glass of orange juice and regular coke have about the same sugar content. The study looked at 101,257 French adults, 79% of whom were women. Consumption of 100 ml of sugary drink consumption was associated with an 18% increased overall cancer risk and a 22% increased risk of breast cancer. Orange juice is healthier than a coke due to the antioxidants present, but the heavy content of rapidly absorbed sugars is a problem. It is better to consume fruits whole. The fiber slows the absorption of sugars and decreases the total amount of sugar it is possible to consume due to the bulk of the food. Researchers suggested follow-up to this research needs to be done.
