More than 25 percent of people older than 65 years have low levels of vitamin D in their blood. Deficiencies in vitamin B12, folic acid, and iron are also common. This is the conclusion of a large study that was conducted by scientists from Helmholtz Zentrum in Munich, Germany. The widespread lack of vitamins and minerals among older people is critical, especially because this population group is increasing. The lack of essential nutrients affects the calcium uptake, immune defense, and nervous system among other things, leaving older people increasingly vulnerable to osteoporosis, influenza, dementia, and a host of other diseases that impair quality of life and burden the entire public health sector.

Atherosclerosis is one of the leading causes of death in the Western world, and the heart is particularly vulnerable. According to a study from the University of Birmingham, Alabama (USA), foods that are rich in potassium such as bananas, potatoes, avocado, and almonds protect against this disease, which takes years to develop. Beware that too much salt and the use of diuretics may deplete the body’s potassium stores.

Fish oil contains the omega-3 fatty acids, EPA and DHA, which are important for normal development of the baby’s brain and immune defense. Pregnant women who eat oily fish several times a week help their babies against developing asthma later in life. Oily fish and fish oil supplements have similar effects. This was shown in two studies from the University of South Florida in Tampa, USA. However, pregnant women should avoid predatory fish like tuna that contain mercury. For those who dislike the taste of fish or who simply do not eat enough, fish oil supplements are an option.

Earlier studies have shown that zinc plays an important role for our health and for preventing esophageal cancer. However, it has been a puzzle to science to understand how zinc protects against this widespread cancer form. Now, Professor Zui Pan and a team of researchers from the University of Texas at Arlington, USA, have identified the mechanisms through which zinc protects healthy cells and prevents cancer cells from spreading in the esophagus. The scientists behind the new study believe that zinc given in the right dosages has a great potential for helping to prevent the disease and serving as an adjuvant in therapy. Their study is published in The FASEB Journal.

Forget about keeping track of calories if you want to shape up. Weight loss is about eating the right kinds of food, and ensuring an optimal blend of carbohydrates, fat, and protein that guarantees satiety for four to six hours so you are not tempted by quick energy fixes. Continue reading and find out more about why it is so important to get plenty of Q10, iodine, selenium, and chromium for permanent results. The question is, why is it difficult to get enough from a normal diet? And why are so many people suffering from weight problems caused by metabolic disorders and insulin resistance?

Type 2 diabetes and early stages of the disease such as insulin resistance are spreading like a bushfire. The good news is that if you consume many antioxidants from fruit, vegetables, berries, tea, and dark chocolate and limit your intake of alcohol, you can lower your risk diabetes risk. This was shown in a new study that is published in the European journal Diabetologia, which focuses on diabetes research.

- and other inflammatory conditions

It is hardly a coincidence that many patients with arthritis feel worse during the winter period where the sun sits too low in the sky for us humans to be able to synthesize vitamin D. In patients with rheumatoid arthritis, there is a direct link between vitamin D levels and neuropathic pain caused by irritated nerves. This was shown in a study that is published in International Journal of Rheumatic Diseases.

All B vitamins work together as a close-knit team, and they are involved in most of the body’s enzymatic processes. For that reason, lacking one or several B vitamins may cause a long list of different symptoms. We humans depend on a regular supply of B vitamins. A wholesome smoothie or a multivitamin in the morning is no guarantee that the body has enough B vitamins for the rest of the day. Add to that the fact that some factors can impair our nutrient absorption and increase our need for B vitamins. But if you keep your body adequately supplied with B vitamins at all times throughout life, it can work wonders.

- and widespread deficiency has serious consequences

It is commonly known that vitamin C has an essential role in our connective tissue and immune defense. However, vitamin C is also vital for the brain. This was demonstrated in a new Australian study of the link between vitamin C and cognitive functions like memory, lingual skills, calculation, and orientation. The scientists also point to the fact that vitamin C deficiency is rather common in western countries, either due to dietary factors or because of conditions that increase the need for the nutrient.

It appears so. Iodine is an essential trace element that is vital for metabolism and estrogen balance. Iodine also helps the body get rid of environmental toxins. In fact, exposure to these toxins increases our need for iodine, and many experts believe that the official recommendations for iodine are too low.

Taking a supplement of vitamin D in combination with your prescription asthma medicine may halve your risk of an asthma attack that would require hospitalization, according to a new meta-analysis from Queen Mary University in London (QMUL). A vitamin D deficiency alone, which is rather common at northern latitudes, can increase the risk of asthma. Therefore, it is vital to make sure to have sufficiently high levels of this nutrient all year round to protect your respiratory tract.

Decades of intensive farming have depleted the soil. As a result, crops lack up to 40% of their essential nutrients, according to a previously published study from University of Texas and a more recent one from Switzerland. Even if you stick to the official dietary guidelines, you may have difficulty with getting enough calcium, selenium, zinc, iron, vitamin B2, vitamin C, and other essential micronutrients that are required for good health.
