Glaucoma is a serious eye disease that is often detected too late. In worst case, it can lead to blindness. A Swedish study from Karolinska Institutet, published in Cell Reports Medicine, shows that supplementation with various B vitamins can improve the metabolism in the eye, which may slow down the deterioration of the optic nerve. It is also important to get enough of the different B vitamins if you want to prevent the condition.

The widespread use of cholesterol-lowering statins increases the risk of developing diabetes, which is linked to cardiovascular disease. It has also been shown that statins inhibit the body’s endogenous synthesis of Q10, which plays a role in cellular energy metabolism and is also a vital antioxidant that protects cells and the cardiovascular system. A new American population study shows that statin users can reduce their risk of developing diabetes by taking a Q10 supplement.

Many people take calcium supplements for bone health. However, this does not significantly reduce their risk of fractures and may even be associated with a range of serious side effects and premature death because calcium from supplements can accumulate in the blood vessel walls and increase the risk of atherosclerosis and heart attacks. A new review article published in Current Osteoporosis Reports highlights this connection. It is also important to be aware that the body’s calcium absorption, distribution, and bone health depend on vitamins C, D, and K2, as well as magnesium.

There are several possible causes of male impotence, and the risk increases with age. Oxidative stress appears to play a role, as this condition contributes to local atherosclerosis, which restricts blood flow to the penis. However, consuming a variety of antioxidants - such as selenium, zinc, vitamins A, C, and E, as well as various carotenoids - may help reduce the risk of impotence, according to a U.S. population study published in Scientific Reports.

Breast milk is the optimal nutrition for babies, but according to a population study from New Zealand, which is published in Nutrients, breastfeeding women often lack vitamin D, vitamin E, manganese, selenium, and other important nutrients. The authors emphasize how crucial it is for both mother and child to be well-supplied with nutrients, as deficiencies can affect the child's development and the mother's health and mood.

During fetal development and childhood, the brain requires a range of nutrients to build the nervous system and support cognitive development. According to a new review article published in Nutrients, widespread deficiencies in vitamins C, D, and A, as well as iron, iodine, selenium, zinc, and other nutrients, may contribute to the development of autism.

High blood pressure is the primary cause of cardiovascular diseases, strokes, and early death. There has primarily been focus on limiting salt (sodium) intake, but now it appears that the balance between sodium and potassium is even more important. According to a study published in the American Journal of Physiology-Renal Physiology, consuming bananas, avocados, broccoli, nuts, and other potassium-rich foods can be beneficial in preventing and treating high blood pressure.

Cholesterol is a vital substance found in all cells and involved in many metabolic processes. Our bodies produce most of cholesterol according to its own needs, and the substance only becomes harmful if it oxidizes and gets embedded in the vessel walls. This has nothing to do with cholesterol levels being high or low. There is evidence that cholesterol-lowering statins inhibit the biosynthesis of Q10, vitamin D, vitamin K2, and several selenium-containing proteins. These compounds are important for energy production and serve as essential antioxidants that protect cholesterol from oxidative stress. Because of their reducing impact, statins often lead to fatigue, muscle weakness, oxidative stress, and other side effects that may eventually increase the risk of atherosclerosis, heart failure, and dementia. This is documented in numerous studies published over recent decades.

Non-alcoholic fatty liver disease (NAFLD) and alcoholic fatty liver disease are associated with the development of other liver diseases, obesity, diabetes, cardiovascular diseases, and cancer. Diet and drinking habits play a major role. Magnesium deficiency also seems to increase the risk of cardiovascular disease and other complications, particularly in individuals with liver-related metabolic disorders, according to a large population study published in Nutrients.

Omega-6 fatty acids, which are mainly found in seed oils, margarine, deep-fried foods, and industrially processed foods, are known to promote the growth of a particularly aggressive type of breast cancer. This was seen in a new study published in Science. Although omega-6 fatty acids are essential for life, many people consume far too much omega-6 through refined diets, and this contributes to the rising incidence of breast cancer and many other diseases. According to previous research, it is important for omega-6 fatty acids to be correctly balanced with omega-3 fatty intake, which can regulate the harmful activity in breast cancer cells. With this insight, researchers see new potential in the prevention and treatment of breast cancer.

It is an established fact that pregnant women should supplement with folic acid, as it reduces the risk of the baby developing neural tube defects in the brain and spinal cord. According to a new Canadian study, folic acid supplementation may also reduce the risk of the child developing neurological damage and autistic behavior caused by lead exposure. It is crucial for pregnant women to get enough nutrients to support fetal development. Also, they should try to avoid environmental toxins as much as possible.
