Alcohol has a greater negative impact on public health than most other things. It is commonly known that alcohol abuse burdens the liver and depletes the body of B vitamins. Now, scientists have also demonstrated that overconsumption of alcohol leaches vitamin C from the body, and they call for further studies to show that vitamin C supplements may help improve the health of alcoholics. It is also possible that vitamin C supplementation can limit the damage of short-term excessive drinking. Their new review article is published in BMJ Nutrition, Prevention & Health.

This almost sounds too good to be true, but scientists from Germany and the United States have discovered that zinc combined with a compound found in cocoa beans, coffee beans, tea leaves, and grapes is able to activate a particular molecule that protects against oxidative stress. In ageing, oxidative stress holds a key role. It is caused by an imbalance between harmful free radicals and protective antioxidants. Although anti-ageing is normally conceived as something that can delay the exterior signs of ageing, it is really more important to slow down internal ageing such as atherosclerosis, fatigue, dementia, and early death in worst case. Many people lack zinc, and deficiencies of this nutrient are widespread and typically observed among vegetarians, vegans, older people, and pregnant and breastfeeding women. What the scientists are telling us now is that it is good for us to enjoy a little dark chocolate, coffee or tea in order to benefit even more from the zinc we get.

- and pre-diabetes and overweight caused by unstable blood sugar

Type 2 diabetes is a global health problem, which is associated with cardiovascular disease, eye disorders, kidney disease, and amputations. Many people unwittingly have an early stage of diabetes called metabolic syndrome. This condition is characterized by insulin resistance, where the cellular uptake of glucose is impaired. This causes insatiety, and you risk eating too many sweets and other quick carbohydrates, which the body is unable to burn and therefore stores ad fat, instead. Many people who struggle with their weight also have insulin resistance and unstable blood sugar that affect their strength of will in terms of food choices and increase their risk of type 2 diabetes. A new meta-analysis has shown that chromium supplements may be useful as add-on therapy for type 2 diabetics. Chromium yeast has the best bioavailability, and specific dietary changes can positively influence your blood sugar levels, waist circumference, and weight.

– and many people are deficient of the nutrient

Overweight is a growing problem, bringing in its wake problems like type 2 diabetes that is spreading like a bushfire. Many people lead a hopeless battle against overweight, unaware that it is their insulin resistance that gets in the way. This is when cells have difficulty with absorbing sugar from the bloodstream. Now, a new Brazilian study has demonstrated that vitamin D increases insulin sensitivity, thereby lowering the risk of overweight and type 2 diabetes. Still, according to existing science, it is not possible to get enough vitamin D without sufficient exposure to sunlight. At our latitude, it is necessary to take a vitamin D supplement throughout the entire winter period.

There are countless reasons why an expecting mother must make sure to get plenty of vitamin D to support the health of her child. Neonates that lack vitamin D are 44% more likely to develop schizophrenia later in life compared with neonates that do not have a vitamin D deficiency. This was demonstrated by Danish and Australian researchers in a recent study. This vital knowledge may help prevent schizophrenia in the future, and the scientists therefore recommend more focus on the importance of having adequate vitamin D levels during pregnancy.

Alzheimer’s disease is the leading cause of dementia. Science has observed changes in the brain that show decades before the disease surfaces. According to a study carried out by the Italian neurologist Lisa Mosconi, eating a Mediterranean diet helps lower the risk of some of these changes that signal the onset of the disease. The study results suggest that one can help prevent this common neurological disorder by eating Mediterranean-style food. What is also important is to focus on having stable blood sugar levels and getting the right nutrients that strengthen and protect the brain.

We need plenty of vitamin D for our bones and immune defense, for preventing cancer and so on, but if we lack magnesium, vitamin D does not work as expected. This is because magnesium is needed for activating vitamin D and enabling it to benefit the body’s cells and tissues. Magnesium also regulates blood levels of vitamin D, more specifically by increasing them if they are too low and lowering them if they are too high. This was demonstrated in a recent study from Vanderbilt University, the United States. The scientists call this highly important information, as there has been conflicting results from studies that compared blood levels of vitamin D in relation to colon cancer and various other diseases. Because magnesium deficiency is a widespread and overlooked problem, there is reason to believe that many people have difficulty with regulating levels of vitamin D in their blood. Also, they risk that their vitamin D does not have the desired effect in terms of preventing a host of different diseases.

A large Irish study has shown for the first time ever that people from 50 years of age and older, who are vitamin D-deficient, are more likely to develop depression.
The study also showed that vitamin D deficiencies are more widespread among seniors, and that taking a vitamin D supplement can make a significant difference. The study supports earlier studies that also link vitamin D deficiency to an increased risk of depression, including winter depression. It is essential to get enough vitamin D all year round, as the nutrient is important for many different processes in the brain and even helps protect against local inflammation that is associated with depression.
