Scientists have determined how to fortify the cassava plant, a staple root crop in many developing countries, with enough vitamins, minerals and protein to provide the poor and malnourished with a day's worth of nutrition in a single meal. The researchers have further engineered the cassava plant so it can resist the crop's most damaging viral threats and are refining methods to reduce cyanogens, substances that yield poisonous cyanide if they are not properly removed from the food before consumption.

Too much alcohol can cause permanent brain damage, such as Wernicke-Korsakoff syndrome, which is largely related to thiamine deficiency. Previous animal studies have shown that alcohol can also cause brain injury and degeneration by inhibiting insulin and insulin-like growth factor. A new study using postmortem human brain tissue has found that chronic alcohol abuse can decrease levels of genes needed for brain cells to respond to insulin/IGF, leading to neurodegeneration similar to that caused by Type 2 diabetes mellitus.

For those patients who receive the nearly 40 million intramuscular injections per year to treat their B12 deficiency, a new oral option may soon exist. According to the National Institutes of Health, vitamin B12 deficiency can lead to a wide spectrum of conditions, such as anemia, dementia and reduced cognitive functioning.

As summer comes and people across America get ready to start slathering on the sunscreen, a note of caution is in order -- a little sunshine is good for you. Studies increasingly are suggesting the value of vitamin D -- often known as the sunshine vitamin, because that's one way you can obtain it -- in everything from bone metabolism to maintaining muscle strength, immune function, reducing hypertension and possibly even playing a role in prevention of cancer and autoimmune disease.

Got memory problems? If you suffer from obstructive sleep apnea, your brain could be to blame. Researchers have discovered that people with sleep apnea show tissue loss in brain regions that help store memory. The findings emphasize the importance of early detection of the disorder, which afflicts an estimated 20 million Americans. Sleep apnea occurs when a blocked airway repeatedly halts the sleeper's breathing, resulting in loud bursts of snoring and chronic daytime fatigue. Memory loss and difficulty focusing are also common complaints. Prior studies have linked the disorder to a higher risk of stroke, heart disease and diabetes.

A study of individuals with age-related macular degeneration (AMD) found that nearly 40 percent of those likely to benefit from specific vitamin/mineral supplements were either not taking the supplements or not using the recommended dosage. The study also showed that some patients used high-dose supplements even in the absence of evidence that these would be effective for their levels of AMD or other eye conditions.

As DNA sequencing becomes cheaper, it will become common for people to have their complete genomes sequenced. Personal genomes will not only tell people about genetic susceptibility to cancer and heart disease, but will also tell them which vitamins and how much can improve their health. A new study shows that one enzyme can be tuned up with vitamins, suggesting that one day we all may take personalized vitamin supplements.

A new vegetarian food that boosts the uptake of iron and offers a good set of proteins. The food, called tempe, is moreover a whole-grain product with high folate content. It is generally accepted in medicine that whole-grains reduce the risk of cardiovascular diseases, and it is also believed that it protects against age-related diabetes and certain forms of cancer. The B vitamin folate is the natural form of folic acid and, among other things, is necessary for normal fetal development.

Organic farmers who let their cows graze as nature intended are producing better quality milk. Milk from grazing cows on organic farms in the UK contains significantly higher beneficial fatty acids, antioxidants and vitamins than its conventional 'high input' counterparts. During the summer, one of the beneficial fats in particular -- conjugated linoleic acid -- was found to be 60 percent higher.

Following the introduction of HAART (Highly Active Antiretroviral Therapy), the survival and quality of life for people infected with the human immunodeficiency virus (HIV-1) have increased in the resource-rich countries. However, with this improved prognosis an increase in long term negative disorders has been observed, namely osteoporosis (the gradual loss of bone mass). Osteoporosis is a multifactorial disease that is characterized by a reduction in bone mass and its mechanical resistance, and leads to an increased propensity to bone fractures.

A chemical compound derived from vitamin A prevents cancer from forming and is being developed by the National Cancer Institute as a daily preventive pill. The compound, which still faces several rounds of clinical trials, successfully stopped normal cells from turning into cancer cells and inhibited the ability of tumors to grow and form blood vessels. If successful tests continue, researchers eventually hope to create a daily pill that would be taken as a cancer preventive.

Scientists have found evidence to suggest an important role for vitamin D in brain development and function, and that supplementation for groups chronically low in vitamin D is warranted. Vitamin D is present in only a few foods (e.g., fatty fish), and is also added to fortified milk, but our supply typically comes mostly from exposure to ultraviolet rays in sunlight.

High blood levels of vitamin D protect post-menopausal women from breast cancer. This connection has been confirmed by research of the German Cancer Research Center. It also shows that a particular gene variant of the vitamin D receptor is associated with an elevated breast cancer risk if the tumor has receptors for the female sex hormone estrogen.

Genetic variations in the body's receptor for vitamin D could increase the risk of breast cancer in post-menopausal women, according to a new study. The researchers explain that vitamin D intake and serum concentrations of its metabolites have been associated with a decreased risk of developing breast cancer. The vitamin plays a known role in controlling calcium levels and influences the differentiation of cells and so could play a part in preventing the runaway proliferation of cells characteristic with cancer.
