It is commonly known that oily fish and fish oil supplements contain the two omega-3 fatty acids EPA and DHA that are good for the brain. Now, scientists from Singapore have discovered a special omega-3 fatty acid that is of particular importance to brain cells that are surrounded by a protective myeline sheath. The scientists say that their discovery may help prevent brain ageing and lead to the development of new therapies aimed at treating neurological disorders like sclerosis that are associated with myelin damage. Their new study is published in Journal of Clinical Investigation and it appears that fish roe is the best source of these special omega-3 fatty acids that are needed to stimulate the myeline sheath.
ADHD: Supplements of vitamins and minerals have a positive effect on emotional disturbances and growth
Over the past decades, the number of children and teenagers with ADHD has skyrocketed, and the diet has a lot to say. According to a new American-Canadian study, supplementing with all the essential vitamins and minerals can improve young ADHD sufferers’ mood, emotional disturbances, and ability to concentrate. The supplements can even stimulate their growth.
Alzheimer’s is an insidious disease and the leading cause of dementia. It’s also one of the major causes of death in old age. Diet plays a major role in preventing the disease. In fact, having high concentrations of the omega-3 fatty acid, DHA, in the blood can halve the risk of developing Alzheimer’s disease, according to a study that is published in Nutrients. DHA (docosahexaenoic acid) is found in oily fish and fish oil supplements. This essential fatty acid is also found in all our cell membranes (including nerve cells) and plays a key role in maintaining our general health and cognitive skills. Unfortunately, modern diets contain far too little omega-3, but science is not quite sure how much we need.
Veganism is on the rise, and experts have different views on whether or not plant-diets are suited for children. A team of Polish scientists has now discovered that children on vegan diets have low stature and lower bone density than children who eat meat and dairy products. Children on vegan diets also are also more likely to lack amino acids, vitamin B12, vitamin D, vitamin A, iron, selenium, iodine, and the omega-3 fatty acid DHA (docosahexaenoic acid). It is particularly important for growing children to get enough nutrients to support their muscles, bones, brain, and a variety of enzyme processes. Also, children on vegan diets should be given relevant supplements to compensate for their shortcomings.
Apparently so. Omega-3 is a class of essential fatty acids with a host of different functions in the body. We primarily get omega-3 from oily fish but it is also found in certain other foods. Our intake of omega-3 has been reduced substantially as a result of altered diets and the use of unnatural animal feed. It appears that having more omega-3 in the blood can help us live longer. This was shown in a study that is published in American Journal of Clinical Nutrition. The question is how do we get enough omega-3?
Preterm babies have a risk of impaired vision, but if they are given supplements of omega-3 and omega-6 fatty acids at the age of two and half years their vision improves. This was demonstrated in a Swedish study that is published in The Lancet Regional Health – Europe. The scientists explain why these fatty acids are so important, not just for eye health but for the brain and for health in general.
Omega-3 and omega-6 fatty acids are vital for our brain function, nervous system, and immune defense but small children get too little of these two essential fatty acids. According to a Canadian study, this increases their risk of chronic inflammation and chronic diseases. The intake of omega-3 from oily fish and shellfish is particularly limited. For children who dislike seafood, a fish oil supplement is worth considering for the sake of their health and development.
In ancient times when our ancestors hunted, they consumed every inch of the animal – from one end to another. Organ meat such as the liver, the heart, and the kidneys were delicacies that contained far more essential nutrients than other parts of the animal. In Western countries, we primarily consume muscle meat. In addition, animals often get unnatural fodder with suboptimal nutrient content. This results in deficiencies and an imbalance between amino acids and fatty acids. In the following article, you can read more about organ meats (also known as offal), bone marrow, and bone broth and their high content of essential amino acids, vitamin B12, iron, selenium, Q10, calcium, magnesium, collagen, glucosamine, CLA, and other vital nutrients. Also, you can read more about why it makes sense to choose meat from free-range livestock.
Poor wound healing, a somewhat common and well-known problem, especially among hospital patients, is associated with huge health costs. Proper wound healing is contingent upon on the presence of different nutrients, and it appears that the ratio between omega-3 and omega-6 fatty acids is particularly important. This was demonstrated in a new study of rats, where higher intake of omega-3 at the expense of omega-6 turned out to have the best effect on the formation of new blood vessels, increased collagen synthesis, and faster wound healing. In the study, which is published in Nutrients, the authors look closer at the fact that modern diets typically contain too much omega-6 and too little omega-3, and this contributes to problems such as cardiovascular disease, overweight, diabetes, and other lifestyle diseases.
Oily fish and fish oil have a high content of the two omega-3 fatty acids, EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), that are important for our brain, nervous system, intelligence, and mental health. Modern diets, however, are to blame for our lack of omega-3. A team of scientists from England has found that supplementation with EPA-rich fish oil for 26 weeks improves mental acuity and reaction time in healthy, young adults. This was not the case with DHA-rich oil fish oil, on the other hand. The scientists were surprised to find that EPA is more important than DHA for these cognitive skills.
Neuroplasticity refers to the brain ability of brain cells to carry out structural and functional changes that are of vital importance to our development and health. It has been shown that neuroplasticity is impaired in connection with various diseases of the central nervous system, including such conditions as depression and dementia. In a review article that is published in Brain Plasticity, scientists have looked closer at how exercise, the Mediterranean diet, and nutrients like omega-3 and vitamin B12 can improve neuroplasticity by way of a protein called BDNF (brain-derived neurotrophic factor). Selenium is also known to be important for the formation of new brain cells, which can help prevent cognitive decline via other mechanisms.
Because COVID-19 mutates from time to time, a vaccine can only provide temporary protection. Also, studies suggest that what makes COVID-19 dangerous is when the immune defense overreacts by launching so-called hyperinflammation that can damage the circulatory system and healthy tissues. The omega-3 fatty acids in fish oil turn out to have the potential to prevent COVID-19 infections from becoming life-threatening due to hyperinflammation. That way, fish oil can also help improve survival, according to a review article that is published in International Journal of General Medicine.
The rate of autism and ADHD has exploded over the past decades, and the problem comes with an enormous human and socio-economic price tag. A study from the University of Copenhagen has shown that fish oil helps adults with autism and ADHD by improving their attention and working memory. In the study that is published in British Journal of Nutrition, the scientists look closer at omega-3 fatty acids in fish oil and their vital role in the brain and nervous system.
Fish oil contains EPA and DHA, two omega-3 fatty acids with a number of different functions in the brain and nervous system. It appears that middle-aged people who consume more oily fish or who take fish oil supplements have improvements in their brain structure and cognitive skills. This was shown in a study that is published in Neurology. The study results are quite interesting because cognitive decline and dementia are increasing problems that affect millions of people worldwide. The study supports previous research where it was seen that having higher concentrations of DHA in the red blood cell can reduce the risk of Alzheimer’s disease by 50 percent.
Depression is often caused by brain inflammation, and it looks as if high-dosed supplementation with EPA, a type of omega-3 fatty acids found in fish oil, may help as it reduces depression in patients with elevated inflammation markers in the blood. This was shown in a study that is published in The Journal of Clinical Psychiatry.
A well-functioning memory is vital for our quality of life. With the increasing number of seniors, however, the dementia rate is on an incline. According to a study that is published in Clinical Nutrition, it looks as if a combination of fish oil and antioxidants such as lutein and zeaxanthin may improve memory in elderly seniors. You can support your brain and memory on a daily basis by eating oily fish or fish oil supplements together with antioxidants from foods such as cabbage, spinach and other leafy greens, and eggs. Another important antioxidant is mezo-zeaxanthin that is found in certain fish and in fish skin.
Migraine is a common neurological disease that reduces quality of life and results in many sick days. Migraine medication does not work for everyone and many people have adverse effects, so it makes more sense to focus on prevention. A new American study shows that diets with higher levels of omega-3 fatty acids from oily fish can reduce the frequency of migraines compared with eating an average diet. People who dislike the taste of fish can take a high-quality fish oil supplement, instead.
Most chronic pulmonary diseases – including asthma, bronchitis, and COPD (Chronic Obstructive Pulmonary Disease) – are characterized by chronic inflammation that makes both the symptoms and the prognosis worse. Fish and fish oil supplements contain specific omega-3 fatty acids that appear to have an anti-inflammatory effect and may therefore be useful as both prevention and therapy for chronic pulmonary diseases. This was demonstrated in a large American population study that also included Europeans. What the researchers also mention is that people who fail to meet the official guidelines for fish consumption are often at increased risk of developing chronic lung diseases.
Omega-3 fatty acids and antioxidants protect the brain in sports disciplines with frequent head injuries
Contact sports like football and boxing are associated with frequent blows to the head that can cause physical traumas and long-term effects. However, a new study that is published in Journal of the International Society of Sports Nutrition suggests that high-dosed supplements of omega-3 fatty acids can protect against the damage caused by head traumas in American football. There is even a positive effect on cardiovascular health and joints. Excessive training and high performance sport can also increase the risk of oxidative stress that is linked to acute injury, inflammation, and subsequent development of neurological disease. It is therefore also important to get plenty of antioxidants like vitamins A, C, and E plus selenium and zinc if you engage in sport at a high level.
Elevated blood pressure, a problem many people have without knowing it, is the major cause of early death. Our lifestyle and what we eat play an enormous role and according to a new meta-analysis that is published in Journal of the American Heart Association, daily intake of three grams of omega-3 fatty acids can reduce your blood pressure. It is possible to get this amount of omega-3 by consuming a serving of oily fish like herring or taking a high-quality fish oil supplement.
Type 1 diabetes can eventually lead to eye damage and if this is not discovered in time it may cause blurry or impaired vision. According to a new study that is published in Diabetes, supplementing with omega-3 for six months can regenerate damaged corneal nerves, so the scientists believe that eating more oily fish or taking a fish oil supplement may represent a promising add-on to existing therapies.
Both diet and lifestyle affect your risk of developing liver cancer. According to a large population study published in Frontiers in Nutrition, regular intake of fish oil lowers your risk of contracting the disease. In fact, it seems that fish oil has a number of different cancer-preventing mechanisms that even reduce the risk of other types of cancer.
Epidemiological studies have shown that relatively high doses of omega-3 fatty acids that are found in oily fish and fish oil supplements have a positive effect on neurodegenerative diseases such as sclerosis, but the underlying mechanisms are not known. A mouse study reveals that one particular omega-3 fatty acid is able to control the immune defense and regulate the inflammatory processes in the central nervous system.
Regular sport is good for you, whereas arduous training and high-performance sport can result in physical injuries, infections, chronic inflammation, and serious diseases due to oxidative stress. This phenomenon occurs as a result of the increased energy turnover, which produces an excess of free radicals that cause damage to cells and tissues. Oxidative stress is also associated with impaired performance, poor restitution, and faster ageing. Our only natural defense against free radicals is the presence of antioxidants, and it is especially things like vitamin C, vitamin E, selenium, zinc, Q10, omega-3 fatty acids, and turmeric that protect against oxidative damage and improve recovery time. According to a review article published in Nutrients, supplements with the right doses of different nutrients can also help boost your physical and mental performance.
- and could potentially be used for prevention and treatment
It is commonly known that omega-3 fatty acids are involved in a number of essential functions in the body. One of the fatty acids, DHA, may even have a toxic effect on cancer cells because they are unable to store the fatty acid correctly. In a new Belgian study published in Cell Metabolism, scientists explain the exact mechanisms. They also suggest that omega-3 supplements may be useful in cancer therapy, especially because the average omega-3 intake from the diet is far too limited and because there is a risk of becoming resistant to medical cancer drugs. The new study puts omega-3 fatty acids and their anti-cancer effects in a whole new light.
ALS (amyotrophic lateral sclerosis) is a potentially life-threatening disease that affects the spinal cord and the motor nerves of the brain. The disease is incurablebut according to an American study that is published in Neurology, it progresses at a slower rate in patients with a higher intake of omega-3 fatty acids from different dietary sources.
Since the 1950s, the rate of asthma has increased dramatically, especially among children and adolescents. Altered diet habits play a significant role, and now a Swedish population study shows that children who get too little omega-3 and too much omega-6 in their diets have an increased risk of developing asthma later in life. There is also evidence that increased intake of omega-3 fatty acids from oily fish or from fish oil supplements can counteract the inflammatory processes that are seen with asthma.
It is vital to take good care of your eyes throughout life to maintain good vision. Our eyes need a number of different vitamins, minerals, and fatty acids that are important for cellular function and for protecting against oxidative stress. In this article, you can read more about vitamin A, vitamin C, vitamin E, B vitamins, zinc, selenium, omega-3 fatty acids, and Q10 and their vital role in maintaining healthy vision. We will also look at certain antioxidants that are found in eggs, salmon, spinach, broccoli, red bell pepper, and blueberries.
Cardiovascular disease is still the leading cause of death, and both diet and lifestyle are of huge importance. According to a new meta-analysis, fish oil, folic acid, and Q10 are some of nutrients with the greatest potential to lower the risk. It is important to underline that supplements are not likely to make much of a difference if the dosage is too low or if the quality of the preparations is poor.
