Omega-3 supplementation in obese pregnant women

In developed countries, the incidence of obesity and overweight has reached epidemic levels. Two-thirds of women in the United States are currently overweight or obese at the time of conception and this is important, among other reasons, because infants born to obese mothers are at increased risk for developing obesity and a metabolic disorder in later life. Therefore, maternal obesity may be a significant factor in perpetuating the obesity epidemic. […]


Long chain omega-3 slow cognitive decline

Consumption of seafood (rich in long-chain omega-3 fatty acids) has been associated with slower decline in semantic memory (which refers to words and other verbal symbols, concepts, facts or beliefs; their meaning and the relations among them) and perceptual speed (the readiness to attend accurately to some details in perception; i.e., the ability to quickly compare visual patterns or symbols). Moderate to high long-chain omega-3 fatty acid intake has been […]


DHA during gestation and infancy

Our cognitive ability (attention, memory, perception, language, problem solving, comprehension, reasoning, calculation, and reading), as humans, is the most advanced in the animal kingdom. It is believed that this is due to the characteristics of our cerebral cortex, the outer layer of the brain. The brain is especially rich in long-chain omega-3 fatty acids, and DHA is the predominant one, since it makes up over 90% of them in the […]


Microbiota and omega-3

Gut microbiota (formerly called gut flora) is the name given to the microbe population living in our intestine. Our gut microbiota includes at least 1000 bacteria types, and can weigh up to 2 kg. One third of it is common to most people, but two thirds are specific to each one of us; in general, it varies according to sex, age, and geographical origin of the person. Gut microbiota has […]


Omega-3 and breast density

A mammogram is an X-ray picture of the breast that allows to detect changes in breast tissue that cannot be felt during a breast exam (the radiologist compares your past mammograms with your most recent one to check for changes). When to start and how often to have a mammogram must be decided by your doctor, depending on your individual characteristics (age, among others). What it is important is to […]


Lower omega-3 intake among smokers

In previous posts, we have already talked about some findings about the relationship between omega-3 fatty acids and smoking: lower omega-3 fatty acids levels have been observed among smokers; the dietary supplementation with EPA and DHA has resulted in a significant decrease in the number of daily cigarettes smoked and in tobacco craving episodes in regular smokers (comparing with placebo treatments); and it has been shown that supplementation with EPA […]
