Omega-3 and testicular volume

In 30-50% of couples with fertility problems the man has poor semen quality. The onset in sperm production begins at puberty, and once it has started, it continues almost constantly until death (although testicular tissue mass decreases with age and this involves changes in sperm production). Sperm quality is measured by the amount, the movement, and the size and shape of sperm. With respect to the amount, the ejaculates of […]

 
 
 
 

DHA, exercise and mitochondrial metabolism

Mitochondria are small structures floating inside the cell and act like a digestive system: they create energy rich molecules for the cell by combining oxygen (from the air we breathe) with the sugars and fats that come from the food we eat. They are the main source of energy for the body. Some cells have several thousand mitochondria (germ cells, for example) while others have none (red blood cells and […]

 
 
 
 

Intake of omega-3 is inversely associated with weight gain

Let’s not fool ourselves, in general we will only gain weight if we eat more calories than we use. It is that simple. If we want to lose weight, we must eat fewer calories and burn more energy through physical activity. If you are trying to lose weight and you are failing to do it, it will also be useful to know that: foods labelled ‘low-fat’ can contain high levels […]

 
 
 
 

Omega-3 and secondhand smoke

Secondhand smoke is the exposition to environmental tobacco smoke: the combination of smoke from the burning end of a cigarette and the smoke breathed out by smokers. Secondhand smoke causes numerous health problems in children, including ear infections (they also have fluid in their ears more often), more frequent and severe asthma attacks, respiratory symptoms (for example, coughing, sneezing, and shortness of breath), and respiratory infections (older children whose parents […]

 
 
 
 

Prevention is ageless

All aging persons develop some degree of decline in cognitive capacity (for example, forgetfulness, decreased ability to maintain focus and decreased problem-solving capacity), and the magnitude of age-related decline accelerates at older ages, but there is considerable controversy about the age at which cognitive decline begins. The question is important because the age at which cognitive decline begins is important in order to choose the optimum time in which to […]

 
 
 
 

EPA and DHA protect from PCBs

Risk factors for stroke (high blood pressure, high levels of cholesterol, atherosclerosis, and diabetes) have been associated with dietary intake of contaminants, including synthetic compounds such as polychlorinated biphenyls (PCBs). PCBs were marketed for nearly 50 years (from 1929 until the end of the 1970s, when they were banned in most parts of the world because of environmental concerns), being used in electrical equipment, surface coatings, inks, adhesives, flame-retardants, and […]
