It prevents cardiovascular disease, cancer and hypertension, but researchers have now found that fish oil also transforms fat-storage cells into fat-burning cells, which may reduce weight gain in middle age.
Good sources of fish oil are mackerel, sardines, oysters, and salmon. Keep in mind that many fish sources high in omega-3 such as tuna and swordfish also contain high amounts of mercury and thus their consumpion should be limited.
Fat tissues don’t all store fat. So-called “white” cells store fat in order to maintain energy supply, while “brown” cells metabolize fat to maintain a stable body temperature. Brown cells are abundant in babies but decrease in number with maturity into adulthood.
A third type of fat cell — “beige” cells — have recently been found in humans and mice, and have shown to function much like brown cells. Beige cells also reduce in number as people approach middle age; without these metabolizing cells, fat continues accumulating for decades without ever being used.
We know fish oil can prevent inflammation in fat cells which can lead to insulin resistance and, ultimately, type 2 diabetes.
Scientists investigated whether the number of these beige cells could be increased by taking in certain types of foods.
“We knew from previous research that fish oil has tremendous health benefits, including the prevention of fat accumulation,” says senior author Teruo Kawada. “We tested whether fish oil and an increase in beige cells could be related.”
The team fed a group of mice fatty food, and other groups fatty food with fish oil additives. The mice that ate food with fish oil, they found, gained 5-10% less weight and 15-25% less fat compared to those that did not consume the oil.
They also found that beige cells formed from white fat cells when the sympathetic nervous system was activated, meaning that certain fat-storage cells acquired the ability to metabolize.
“People have long said that food from Japan and the Mediterranean contribute to longevity, but why these cuisines are beneficial was up for debate,” adds Kawada. “Now we have better insight into why that may be.”
A study published in Environmental Research indicates that omega-3 polyunsaturated fatty acid (PUFA) intake reduces cardiovascular disease risk factors. Additionally, arterial stiffness was related to environmental contaminants found in fish. However, the environmental contaminants did not outweigh the benefits of fish intake on carotid artery plaque formation. Currently, an estimated 80 million Americans have cardiovascular disease. Furthermore, one in three deaths in the U.S. is attributed to cardiovascular disease. (more…)
A new study just published in the Journal of Nutritional Biochemistry appears to be the first to provide what the researchers call “unequivocal evidence that omega-3s reduce cancer risk.”
So, how much of a risk are they talking about? A huge one. The scientists from the University of Guelph found that a diet rich in omega-3 fatty acids (healthy fats found in cold water fish such as salmon and certain plant foods, including walnuts) can inhibit the growth of breast cancer tumors by 30 percent, especially if started early in life.

Fish is brain food, and that’s not just something moms say to get kids to eat up. It’s true — and new research shows how the omega-3 fatty acids in fish can actually make kids smarter.
Fish oil during pregnancy and early childhood can increase the IQ by an average nearly 4 points, according to the study conducted by researchers at NYU.
Want to know how big that is? That’s almost equivalent to the boost some kids get when they’re enrolled in an early education program.
Not bad for something that takes no time, requires no teachers, is inexpensive, widely available, perfectly safe, and comes with dozens of other benefits in kids and adults alike. (more…)
Nutritional health supplements have been proven to be an intelligent choice by parents of autistic children. If your healthcare provider “doesn’t believe in them” – then I suggest you find another health professional. There is no debate – good nutrition is essential for your child’s health – now let’s talk about what really works.
Many of the clients I see are young children with autism. As a homeopath and a CEASE practitioner I not only listen to the parent or the child describe their chief complaint, but also observe their appearance, demeanor, behavior and a host of other items as part of the intake. One of the items noted quite often in kids with autism is pasty skin or looking malnourished. (more…)
While we all pay attention to incorporating vitamins and minerals into our diets, are you getting enough critical nutrients? There are some nutrients that you need to pay special attention to — ones you probably aren’t getting enough of, yet they’re essential to primary cell functions. Here are seven critical nutrients which are depleted in more than 70 percent of diets.
Two billion people may have a zinc deficiency, yet it’s an essential mineral required by the body for maintaining a sense of smell, keeping a healthy immune system, building proteins, triggering enzymes, and creating DNA. Zinc also helps the cells in your body communicate by functioning as a neurotransmitter. A deficiency in zinc can lead to stunted growth, diarrhea, impotence, hair loss, eye and skin lesions, impaired appetite, and depressed immunity. (more…)
They say you can’t stop aging. And I say maybe that’s true — but you certainly can slow it down.
Cutting-edge research has found what just may be the fountain of youth for some of the most critical cells in the body — and the best news of all is that you may already be getting the life-extending benefits right now if you’re taking fish oil.
And if you’re not, you might want to get started. (more…)
