Mechanisms by which omega-3 fatty acids benefit eye health revealed

Omega-3 fatty acids provide many health benefits.  Over the last several years, research involving omega-3 fatty acids has revealed a positive, direct effect on eye health. Retinopathy, age-related macular degeneration (AMD), as well as other diseases that affect the nerves and tissues of the eye, negatively impact the lives of millions, often leading to impaired vision or blindness.
A new study in Science Translational Medicine (February 2011) reviewed the impact of omega-3 fatty acids on eye health and the pathways by which its beneficial effects occur.  It was found that 4-HDHA, a metabolite of the omega-3 fatty acid, DHA, selectively promoted the growth of healthy blood vessels while inhibiting the growth of abnormal (unhealthy) vessels.  Researchers believe these findings further highlight the beneficial effects of this omega-3 fatty acid and may serve as a foundation for exploring new treatment regimes for eye-related diseases as well as other diseases that affect the body.

Supplements of magnesium may improve sensitivity to insulin

From MA Blog:
Magnesium is an important mineral that is essential for human health. Dietary surveys reveal that many Americans do not meet the RDA for magnesium (320 mg/d for women and 420 mg/d for men). The potential health benefits of magnesium have been gaining recent interest and it is reported as one of the fastest growing mineral supplements.
A recent clinical trial evaluated the effect of oral magnesium supplementation on insulin sensitivity. Subjects received either 365 mg/day of magnesium or placebo for six months. Daily supplementation of the mineral improved insulin sensitivity and blood glucose scores. The researchers suggest there are several mechanisms which may be responsible for the beneficial effect of magnesium on insulin sensitivity. They say these include, “direct effects of magnesium on the insulin receptor and its downstream signaling process, enhanced enzyme activities involved in glucose utilization, prevention of an intracellular calcium overload supposed to negatively affect insulin sensitivity, and finally, anti-inflammatory effects known to improve insulin resistance.”
The study supports eating a wide variety of foods containing magnesium such as green leafy vegetables, nuts, beans and meats. Along with eating a healthy diet, magnesium supplementation can optimize health and possibly prevent certain diseases.

Leptin Sensitivity: The Facts

 From MA Blog:
Weight loss is difficult enough. But for some people, no matter how hard they try, it seems their efforts are being thwarted by a little-known hormone called leptin.
What is leptin?
Named after leptos, the Greek term for “thin,” leptin is a protein manufactured by the body’s fat cells. It appears that the level of leptin circulating in the bloodstream is directly proportional to the total amount of body fat, or adipose tissue, a person possesses.
Leptin wasn’t discovered until 1994, but continues to be one of the most fascinating hormones in the field of weight management. Research is emerging that shows leptin to be equally important to insulin in regulating proper body weight, which may be one of the reasons people on diets experience “rebound” weight gain.
So how does leptin play a role in weight loss?
Leptin acts in the hypothalamus, a part of the brain that is responsible for coordinating appetite and satiety. Essentially, it is this role that tells us when to stop eating.
A variety of signals control the amount we eat: sensory signals such as smell and taste, physical signals such as a feeling of fullness, and chemical signals from the gastrointestinal system to the brain. Normally, the process begins when the brain notes the amount of leptin secreted by fat cells. If the brain determines these leptin levels are normal, it shuts off the signal to store extra calories as fat. The body no longer feels like eating because the brain – with the help of leptin – has told the body to stop eating.
One would think that it would be desirable to increase leptin levels. However, in most overweight people, leptin levels are actually excessively high due to leptin resistance, a process similar to the concept of insulin resistance.
Sometimes – especially in today’s society, with food surrounding us at all times and the urge to overeat common – the brain’s leptin receptors can become desensitized. Once a person becomes leptin sensitive, the body has a difficult time transporting leptin past the blood brain barrier to the hypothalamus where it is needed to send satiety signals. Even though blood levels of leptin may be excessively high, brain levels are insufficiently low, resulting in food cravings and weight gain. The brain believes the body is in a famished state and tells it to continue to store fat. This sensitivity to leptin can cause the brain to believe it is in a constant state of starvation.
For example, when serial dieters – those who are continually losing and gaining weight – lose fat through diet and exercise, the brain thinks it is starving and tells the body to hold on to its fat stores. This is when the weight usually roars back. That’s because the body will fight harder against losing fat than it will against gaining fat. That’s why most people find it a whole lot easier to get fat than they do to get lean. As someone gains weight, the body tries to maintain the status quo, but the baseline has moved higher. After the body adjusts to a heavier, new status quo, it’s hard to slim down again.
How do I control leptin?
Research indicates that lowering leptin levels in overweight people can restore this malfunctioning leptin system and trigger weight loss. Here are a couple of ways that you can get your body back working for you:
  • Suppress the appetite. We need to eat, but we don’t need to eat everything.
  • Inhibit carbs from being absorbed by the body. Not all carbohydrates are created equal. Carbohydrates in fruit and vegetables are the good carbohydrates. Other carbohydrates, like starches, cause your blood sugar to soar and disrupt your hormonal balance. While these foods aren’t bad for you, eating too much of them throws hormones out of balance and makes leptin ineffective as an appetite suppressant.
  • Stop carbs from being converted to fat. Even though we want to reduce the amount of carbohydrates we take in, the body still needs carbohydrates. What we don’t want are excess carbohydrates being converted into fat – which we have learned is a main component of leptin sensitivity. Natural ingredients like White Kidney Bean Extract have been shown to allow some carbohydrates to pass through the body undigested, stopping them from eventually being converted into fat.
By supporting a normal response to leptin – suppressing the appetite, inhibiting the amount of starchy carbohydrates being absorbed by the body, and helping stop the body from converting excess carbohydrates into fat – you can finally give your body the support it needs to keep off the weight.
