Fight against obesity with exercise in a heart-healthy way, with DHA

In a study designed to evaluate the effect of fish oil supplementation rich in DHA, with and without regular exercise, on heart rate variability (the variation in the time interval between heartbeats) in overweight adults with risk factors for coronary disease, fish oil supplementation improved heart rate variability (compared with placebo). And it also reduced heart rate at rest and during submaximal exercise (physical activity whose intensity increases at regular [...]


Winning the battle against free radicals

Media tell us that free radicals are bad, but, what are “free radicals”? They are molecules that are formed when we do exercise, when our body produce energy and when we are exposed to environmental factors as cigarette smoke, environmental pollution or UV radiation. The feared free radicals are such because they can cause oxidative stress, which is the result of an imbalance between pro-oxidants and antioxidants molecules, and this [...]


Where is the border line between permissive diet and poor nutrition?

At this stage, we already know that long-chain omega-3 fatty acids from fish oil play an important role in cognitive performance throughout all life phases, from childhood (brain development) to old-age (to defer cognitive decline and prevent age-related eye-diseases). With respect to childhood and according to some studies, it would seem as if children with low literacy ability and who are malnourished with low omega-3 intakes may benefit most from [...]


Men are from Mars, women have more effective uptake of omega-3

Recently, a group of researchers at Swinburne University of Technology in Melbourne (Australia), which were investigating the effects of taking multivitamin and fish oil supplements together on the incorporation of Omega-3 fatty acids into red blood cells, have reached the conclusion that it was influenced by dosage, the concurrent intake of vitamin/minerals (some of them improved the incorporation) and gender: women have more effective uptake of these fatty acids. In [...]


Omega-3, cardiovascular function and exercise

Regular and moderate exercise strengthens your heart, even if you have heart disease (if this is the case, talk with your doctor about it). Furthermore, it lowers your blood pressure and cholesterol, helps manage stress, improves sleep and can help you to stay at a healthy weight. The cardiovascular system has important functions during exercise, among others: delivers oxygen and nutrients to muscles, and oxygenates blood by returning it to [...]


Omega-3 supplements, a good investment in our health

Did you know that, according to consulting firm Frost & Sullivan, around 75% of total United States health care expenditures (the sum of public and private health expenditure) are spent on preventable diseases as coronary heart disease, diabetes, age-related eye disease and osteoporosis? And that the use of certain dietary supplements could save a lot of money in health care costs? Let’s take the example of coronary heart disease, a [...]
