Type 2 diabetes is spreading like a bushfire, and most people will be affected by periodontal disease at some point in their life. Now, science has discovered that lack of vitamin D, which is also increasingly common, enhances the risk of both diseases. Their observation is based on new study that sheds light, for the very first time, on vitamin D and its role in preventing and treating the two conditions.

- but specific nutrients protect you

People, who eat nutrient-depleted diets, have an increased risk of contracting cancer, according to a French study that is published in PLoS Medicine. The scientists therefore recommend labeling food to help consumers make healthier choices. In the Nordic countries, we already have the “Keyhole label” on certain healthy food items, but even if you follow the official dietary guidelines, it may be difficult to get enough vitamin D and selenium, both of which are nutrients with several anti-cancer mechanisms.

A pregnant woman can support the development of her baby’s brain and vision by consuming oily fish regularly, according to a new Finnish study. Meanwhile, a new Danish study shows that fish oil supplements given to pregnant women give their offspring a better start at life because of their content of omega-3 fatty acids. Unfortunately, the consumption of omega-3 has gone down, and pregnant women are discouraged from eating tuna and other good sources of omega-3, as these fish contain mercury. Health authorities should take this dilemma into account and possibly recommend high-quality supplements of purified fish oil to pregnant women and small children – just like they recommend extra folic acid, iron, and vitamin D. Pregnant vegetarians and vegans should pay careful attention and make sure that their child gets enough omega-3.

- and a common trait in most chronic diseases

Although chronic inflammation is not something that you feel as such, it sets the stage for a number of symptoms and a host of different diseases including fatigue, overweight, diabetes, cardiovascular disease, rheumatism, metabolic disorders, asthma, periodontal disease, bowel infections, depression, Alzheimer’s disease, sclerosis, and cancer. Not surprisingly, people are more and more hooked on the anti-inflammatory lifestyle, and we will take a closer look at studies showing how fish oil, vitamin D, selenium, magnesium, and zinc contribute to preventing and fighting inflammation, related diseases and premature death. Any nutritional supplements must be of a proper quality that the body can absorb, and they should contain therapeutic dosages.

- but is heavily overrated in energy beverages and breakfast cereals

Vitamin B6 is essential for the energy turnover, nervous system, hormone balance, and a number of other important functions. Vitamin B6 has been added to many energy beverages and breakfast cereals as an “energy booster” or a way of telling consumers that the product is healthy. But don’t be fooled. The same products often contain loads of sugar and caffeine, which burdens the blood sugar balance and the nervous system. It is therefore far better to get vitamin B6 by eating a balanced and healthy diet, possibly topped off with a supplement if necessary. Those who are likely to benefit from a supplement are strict vegetarians and vegans, pregnant and breastfeeding women, and seniors.

Perhaps so. More and more studies reveal that it helps to take large quantities of Q10 and a vitamin B3 derivate. Q10 and vitamin B3 are both essential for the body’s energy turnover, which takes place inside the mitochondria of the cells. A more recent study shows that taking supplements of the mentioned nutrients can also have a positive effect on the heart, which is the body’s central motor.

– whereas the often scolded cholesterol is good for you

Cardiovascular diseases account for more deaths than anything else. Still, there is a lot of discussion about the diet and its impact on cardiovascular health, typically when it comes to the question of avoiding fat and choosing margarine instead of butter. A team of Czech scientists decided to study diet habits among different populations and compare these with the risk of cardiovascular disease and premature death. Their study shows that there is no need to be afraid of cholesterol. In fact, the official dietary guidelines could easily do with an adjustment. At the same time, it is important to reduce our intake of carbohydrates and omega-6 fatty acids that are the real culprits. Finally, it is essential to increase the intake of omega-3.

– but what about the mercury? – but what about the mercury?

Oily fish is a great source of the essential omega-3 fatty acids, EPA and DHA, which are important for the development of the brain and nervous system of the unborn child. Pregnant women with low levels of these two omega-3 fatty acids have a statistically significant increased risk of preterm delivery compared with pregnant women who have high levels of EPA and DHA in their blood. This was shown in a study from SSI in Copenhagen, carried out in collaboration with Harvard T.H. Chan School of Public Health in Boston, the United States. The problem is that many women are afraid to eat oily fish during their pregnancy because of the risk of mercury poisoning. So which fish are the safest for consumption – and what about fish oil supplements?

- and that may down to a lack of the sleep hormone melatonin

Sunlight is important for our mental health for various reasons. At northern latitudes, we are exposed to less sunlight. According to a new American study, that increases your risk of the OCD, a psychiatric disorder characterized by compulsive thoughts and behavior. The scientists point to the fact that people with OCD often have delayed 24-hour rhythm and get to bed late at night, and they theorize that these disturbances of the circadian rhythm and lack of melatonin may play a role. This presents new potential in the treatment of the disease, and morning light is part of it. Melatonin supplements may also be worth trying.
