Researchers link vitamin D deficiency to seasonal affective disorder – Medical News Today

January 31, 2015 by Shaklee Distributor Douglas Adams | No Comments | Filed in Uncategorized

The research team – led by Alan Stewart of the College of Education at the University of Georgia – publish their findings in the journal Medical Hypotheses.

Seasonal affective disorder (SAD) – a form of depression that usually begins in the fall, continuing throughout the winter months – affects up to 10% of the US population. Symptoms include feeling sad or anxious, fatigue, concentration problems, irritability and feelings of guilt and hopelessness.

Although the exact cause of SAD is unclear, numerous studies have suggested the condition may be triggered by lack of sunlight. SAD is more common among people who live at high latitudes or areas with lots of cloud.

One hypothesis behind SAD is that reduced sunlight exposure interferes with the body’s biological clock that regulates mood, sleep and hormones. Another theory is that lack of sunlight causes an imbalance of neurotransmitters – such as dopamine and serotonin – which regulate mood.

5 Vitamins and Nutrients You Need for a Happy, Healthy Winter

January 30, 2015 by Shaklee Distributor Douglas Adams | No Comments | Filed in Uncategorized

1. Iron

Why you need it: Iron deficiency, or anemia, often results in a weakened immune system, which leads to increased frequency of infection, reports the National Health Service. Iron deficiency is also known to cause fatigue (due to lack of red blood cells), dizziness, and headaches. The lethargy reported among anemic individuals tends to result in decreased physical activity, further compounding their risk of illness.What do you think?

How to get it: The U.S. Department of Health and Human Services recommends that individuals maintain a balanced diet consisting of iron-rich foods such as beef, lentils, spinach, white beans, and even dark chocolate. Check its website for further information on what this mineral can do for your body and how to ensure you’re getting enough.

A daily multivitamin is a great nutrition insurance policy. Some extra vitamin D may add an extra health boost.

True, a healthy diet should provide nearly all the nutrients you need. But many people don’t eat the healthiest of diets. That’s why a multivitamin can help fill in the gaps, and may have added health benefits.

The folic acid in most multivitamins helps prevent neural tube defects in newborns, if women take it before they become pregnant; folic acid may also lower the risk of heart disease, colon cancer, and breast cancer.

Vitamin D from a multivitamin or single supplement can lower the risk of colon and possibly many other cancers, as well as other chronic diseases.

Of course, there can be too much of a good thing. It’s important not to go overboard with vitamins. While a multivitamin and a vitamin D supplement can help fill some of the gaps in a less than optimal diet, too much can be harmful.

In general, stick close to standard recommended doses in a multivitamin. And since your multivitamin will likely contain all the folic acid you’ll need, stay away from cereals, protein bars, and other foods that are super-fortified with folic acid.

Read enough nutrition news, and you’ll see that not all scientists agree on multivitamins. Some say that there’s not enough proof that multivitamins boost health, so they don’t recommend them. Other scientists point to studies that seem to show a link between multivitamin use and increased risk of death.  But those studies are flawed. Looking at all the evidence, the potential health benefits of taking a standard daily multivitamin seem to outweigh the potential risks for most people.

5 Quick Tips: Getting the Right Vitamins

1. Eat a healthy diet. A multivitamin provides some insurance against deficiencies but is far less important for health than the healthy food patterns described on this website. Choose a diet rich in fruits, vegetables, whole grains, nuts and healthy oils, and low in red meat and unhealthy fats—let the Healthy Eating Pyramid be your guide.

2. Choose a daily multivitamin. A daily multivitamin is an inexpensive nutrition insurance policy. Try to take one every day.

3. Think about D. In addition to its bone health benefits, there’s growing evidence that getting some extra vitamin D can help lower the risk of colon and breast cancer. Aim for getting 1,000 to 2,000 IU of vitamin D per day—this likely will require an extra vitamin D pill, in addition to your multivitamin.  For more information, see the vitamin D section of The Nutrition Source.

4. Say no to “megas.” In general, avoid mega-dose vitamins and mega-fortified foods. Higher doses of vitamin E may help to prevent heart disease, but in general, the amount in a standard multivitamin is enough to have health benefits. A standard multivitamin also has a day’s worth of folic acid, so you should avoid foods that have high amounts of folic acid added to them. Vitamin D is an exception, as many people need more than the RDA.

5. Avoid “super” supplements. Don’t be swayed by the wild health claims of the many health supplements advertised on TV and the Internet. If they sound too good to be true, you can be sure they are. Save your money for healthy food and a good vacation.

A Daily Multivitamin Reduces Cancer Risk in Older Men | TIME.com

January 28, 2015 by Shaklee Distributor Douglas Adams | No Comments | Filed in Uncategorized

There hasn’t been strong evidence to support the idea that vitamins can combat cancer—until now.

In the first rigorous, long-term study of multivitamins and their effect on cancer, older men who took daily vitamins lowered their risk of cancer by 8% compared to men who skipped the supplements over an average of 11 years of follow up.

Participants included 14,641 male U.S. physicians ages 50 and over who were enrolled in the Physicians’ Health Study for 11 years. The men were randomly assigned to take a multivitamin —Centrum Silver — or a placebo, and neither they nor the scientists were aware of their status. Overall, they were healthy; two-thirds exercised on a regular basis and only 4% were current smokers. The doctors’ mean age was 64. Nine percent (1,312) reported a history of cancer (excluding nonmelanoma skin cancer).

Soy Protein Isolate and Soy Products Health Benefits and Risks – Shape Magazine

Q: Should I avoid soy protein isolate?

A: Soy has become a very controversial and complicated topic. Historically Asian populations have consumed large amounts of soy products while also having the longest and healthiest lives in the world. Research regarding soy protein and cardiovascular health became so robust that it was awarded a health claim, allowing food companies to state that “25 grams of soy protein a day, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease. A serving of (name of food) provides X grams of soy protein.”

But for every health benefit of this complete plant-based protein source, you’ll also hear of a potential detrimental effect, including an increased risk of certain cancers, disturbed hormonal balance, disrupted thyroid function, or intake of pesticides and toxins.

Easing some concerns, the Agency for Healthcare Research and Quality (AHRQ) released a nearly 400-page report on the effects of soy and soy isoflavones (antioxidants found in soy), concluding that, “For all outcomes, including adverse events, there is no conclusive evidence of a dose-response effect for either soy protein or isoflavone.” However, because soy products come in such a wide variety—whole soy, fermented soy, soy protein isolate, and others—confusion continues to ensue.

When it comes to being couch potatoes, Americans aren’t alone. Physical inactivity has become a global pandemic, say researchers in a series of related papers  published in the journal Lancet. According to one of the reports, lack of exercise causes as many as 1 in 10 premature deaths around the world each year — roughly as many as smoking.
