Why Fish Oil is NOT the Best Omega-3 Source

May 28, 2008 on 7:22 am | In Uncategorized | 1 Comment

ecology, fish, farmed fish, omega-3, fish oil, krill oilCallum Roberts, professor of marine conservation at York University, predicts that by 2050 half the world population will have to go without fish; all that will be left for them may be “jellyfish and slime”.

Ninety years of industrial-scale exploitation of fish has led to an ecological meltdown, and whole biological food chains have been destroyed.

North Atlantic fish stocks have been in decline for well over a century. Fish catch records from the 1920’s onwards show that, despite the enormous improvements in technology, catches of the great Atlantic species have remained constant or slowly declined.

Why has the international community failed so badly in its attempts to stop this long-heralded disaster?

“Quite simply,” Roberts says, “agreements and deals brokered by politicians will never be satisfactory. They always look for the short-term fix.” Quotas for fishing fleets are on average 15 to 30 percent higher than those recommended as safe by scientists. And often, for less threatened species, the quotas are set 100 percent higher than the science recommended.

10 Ways to “Get Primal”

May 21, 2008 on 2:30 pm | In Uncategorized | No Comments
By Mark sisson

I advocate the Primal Blueprint Lifestyle, that is, a health philosophy that in large part acts to mimic the diet and physical activity of our pre-agricultural ancestors.

And, while we’ve explained in the past what it means to “Get Primal,” we figured what’s not to love about a bulleted list that reminds us how to incorporate these methods into our everyday lives.

Read on to learn how you can get primal on every level on every occasion:

Hike:

Whether it was searching for food, shelter or just greener pastures, our ancestors spent a lot of time taking the heel-toe express! (Though, it wasn’t exactly heel-toe in those days.) These days, of course, we have planes, trains and automobiles to get us from A to B, which means hoofing it has become our least likely mode of transport. To get back to the Primal Blueprint, set aside some time every week to participate in sustained activity as a way to return your body to its natural state (that is, being in a constant state of motion). And, although hiking was the primary modality for sustained exercise for our predecessors, feel free to substitute it for biking or any other low-level physical activity you can do for a long period with little interruption.

Sprint:

Although eat or be eaten is no longer really considered a threat in today’s society, for our ancestors, it was a pretty big (and potentially lethal) deal. The solution? Run fast, run hard, and run for your life! You can incorporate these same theories by adding a series of short sprints into your exercise routine (see Mark explain his sprint routine here). The idea here isn’t necessarily to be the fastest kid on the block (although that would be awesome), but rather to give all you’ve got for a brief period of time. Also, bear in mind that this concept of going hard and fast for a few seconds isn’t limited to the act of sprinting; you could try water sprints, power cycling, jump rope intervals or any other activity that requires short, intense bursts of energy.

Lift Hard:

Think Cavemen killed time pounding weights in a dingy gym? Think again! Our ancestors tested their strength only in real-life situations (as opposed to having a pose-off with the meathead in the cut-off shirt!) and grew strong by doing, for the most part, weight bearing exercises. Naturally, they focused on activities that would help them carry out real life functions. Want to work out like your primal ancestors? Try weight bearing activities such as squats or dead lifts, which our ancestors did when lifting a heavy rock or log for building; lunges, which mimic the action of transversing steep terrain or stepping into a throw; pull-ups and standing rows to mimic the movement of pulling a heavy object towards the body; pushing, to mimic the motion of… well, pushing things; and twisting motions such as medicine ball throws or cable woodchoppers, which our ancestors did when throwing spears or hoisting objects. For a new challenge (and an exercise that combines just about all of the above motions, try the Turkish get-up:

Ditch Grains and Sugar:

With the tagline “so simple even a caveman could do it,” the commercial suggests that our ancestors were, well, not the sharpest tools in the shed. But, clearly they were smart enough to shun grains and sugar (a feat that the majority of current day Americans have yet to accomplish). In fact, according to some anthropologists, our ancestors only consumed about 80 g of carbohydrates per day, largely because sources of carbohydrates – such as grains, beans and potatoes – are toxic in raw form. To keep it primal, avoid all grains, including bread, pasta, rice and noodles, and all refined sugar. It should also probably be noted that the majority (if not all) of processed foods are packed with carbs – either in the form of a grain, sugar, or both – so it’s best to cut those out too!

Eat Meat and Fish:

When dinner time rolled around for our ancestors, they weren’t exactly reaching for the yellow pages! Instead, they were reaching for a spear, ax or some other weapon to catch their meal. While we’re certainly not advocating that you begin hunting for your own entrees (people might talk!) we do recommend that you begin thinking about your diet in a way that resembles their dietary habits. That is, if you can’t catch it or find it in nature, you can’t eat it. In short, opt for meat and fish and don’t get hung up on the fat content. Not only is fat integral to health, it will also help keep you feeling satiated longer!

Eat Berries, Nuts and Unbridled Amounts of Veggies:

Again, when selecting foods, remember that you’re playing the role of the hunter and gatherer, so feel free to indulge in foods you would find in nature. Specifically, the Primal diet recommends berries, which are low in sugar and packed with vitamins, antioxidants and other beneficial nutrients, and nuts, including walnuts, brazil nuts, macadamias and almonds (but not peanuts which are a legume and should also be avoided for fear of aflatoxins). When it comes to vegetables, seek out root vegetables including carrots, turnips, parsnips, rutabagas and Swede (but not potatoes or other starchy, high-carb varieties), leafy greens, tomatoes and other brightly-hued vegetables (which not only add color to dishes, but also seriously improve the nutrition value).

Drink Water:

Although there is some back and forth about how much water our early ancestors actually consumed (with some anthropologists suggesting that early man got most of his water from the vegetables he consumed as opposed to risking his life standing in line with the other predators and prey at the local waterhole), the reality is that even if early man didn’t consume that much pure water, he certainly wasn’t reaching for a Coke. Get back to your primal roots by ditching the Gatorade, the soda (including the diet ones – they’re nearly as bad!) and especially the juice. All you really need is water, and lucky for you, it’s as easy as turning on the tap.

Sleep Smart:

When the sun went down, early man started prepping for bed. When the sun sets today, most men (and women) will do the dishes, watch Grey’s Anatomy, finish up paperwork, pay bills and check their email before falling asleep with the television blaring Conan O’Brien. No offense to Mr. O’Brien, but when nature starts heading to bed, so too should you. To catch Zzzs like our ancestors, remove all electronics from the bedroom and focus on creating an environment that is dark, quiet and serene. Also, while it might seem counterintuitive to not close the blinds, allowing natural light to be your wake-up call is far more refreshing (and natural) then waking to the shrills of an alarm clock.

Relax:

As much as we harp on about how hard early man had it (what with having to work hard to survive and all that), make no mistake, early man liked his downtime too! Unlike our ancestors, however, many of us tend to spend our downtime plunked in front of the TV or computer engaged(?) in mindless activity for hours on end. To get back to our primal roots, select an activity that will clear your mind and help you recharge and refocus. And don’t forget that part of this getting up and moving around a bit.

Crack a Coconut, Spear your Dinner and Sleep in a Cave:

Ok, maybe we’re kidding on this last one. But imagine how primal it’d make you feel!

Weight

May 15, 2008 on 2:54 pm | In Uncategorized | No Comments

The size of your waist can tell you far more about the state of your health than the number on a bathroom scale. Studies have linked larger waist sizes to higher risk for heart attack, cancer, diabetes, dementia and even incontinence.

Last month, Harvard Medical School researchers reported on a study of 44,000 nurses that showed even normal-weight women face twice the risk of premature death from heart disease or cancer if they are thick around the middle. Other studies have shown similar risks for men.

The notion of waist size as a barometer of health has been around for years, but the vast majority of doctors still put patients on a scale and calculate their body mass index, which measures weight relative to height.

But many studies of both men and women now suggest that it is not how much you weigh but where you carry your weight that matters most to your health.

In March, an analysis in The Journal of Clinical Epidemiology showed that body mass index is the “poorest” indicator of cardiovascular health, and that waist size is a much better way to determine, for both sexes, who is at a higher risk for hypertension, diabetes and elevated cholesterol.

Studies suggest that health risks begin to increase when a woman’s waist reaches 31.5 inches and her risk jumps substantially once her waist expands to 35 inches or more. For men, risk starts to climb at 37 inches, but it becomes a bigger worry once their waists reach or exceed 40 inches.

However, those numbers are based on averages and are not always useful for very tall or short people, children or certain ethnic groups. Among the Japanese, for instance, health risks start to increase for men with a waist size above 33.5 inches, but for Japanese women, risk does not increase until their waists expand to 35.5 inches.

Last month, The International Journal of Obesity suggested that, particularly for young people, the waist-to-height ratio might be a better indicator of overall health risks. Put simply, your waist should be less than half your height.

But a thick waist does not always correspond with poor health. One extreme example is the Japanese sumo wrestler who despite his massive size still might have the cardiovascular health of a slimmer athlete. Sumo wrestlers typically store fat just beneath their skin, where it doesn’t cause harm, rather than deeper in their abdomen.

Still, for most people, waist size is important. “We’ve known for a long time that people who tend to deposit fat inside their abdomen are the ones who have the highest risk for diabetes and heart attacks,” said Dr. Arya M. Sharma, chairman of obesity research and management at the University of Alberta. “For most people who are not sumo wrestlers, it’s actually quite a good indicator.”

Having a large waist means you are more likely to have fat around your heart, liver and even ordinary muscles, and it signals that you should be screened for other health problems, like insulin resistance and high cholesterol — particularly high triglycerides.

Losing even a little weight can have a big effect. In a small study, 20 severely obese patients who were put on a very low-calorie diet lost an average of 20 percent of their body weight. That translated into only a 19 percent drop in body mass index, but waist size fell 23 percent. Inside the body, the effect was even greater. Using imaging technology, researchers found that the layer of fat around the heart shrank by an average of 32 percent, according to a report this month in the medical journal Obesity.

Stress hormones have also been linked to abdominal fat. In one study, researchers used blood and saliva tests to measure the stress response of 67 women, ages 18 to 25, who were subjected to speech and math tasks. Women who experienced the most stress during the tasks were more likely to have a thicker waist than the women who were not stressed, according to the March report in The International Journal of Obesity.

Doctors say that while diet and exercise can help shrink your waist, most people find it tough to succeed.

If you have a large waist, your first goal should be to stop gaining weight, Dr. Sharma said. Exercise and improving the quality of the food you eat will lower your risk for heart and other problems, even if you never lose pounds or inches.

“You might want to focus on being as healthy as you can and not obsess about your weight,” Dr. Sharma said. “Obesity management is not about treating numbers on a scale. It’s about improving people’s health.”

The Vitamin You Need to Prevent Prostate Cancer

forgotten vitamin, vitamin K, vitamin D, K1, K2, prostate cancer, cancer, prostateIncreased intake of vitamin K2 may reduce the risk of prostate cancer by 35 percent, according to the results of European Prospective Investigation into Cancer and Nutrition (EPIC).

The potential benefits of K2 were most pronounced for advanced prostate cancer. Vitamin K1 intake did not offer any prostate benefits.

The findings were based on data from more than 11,000 men taking part in the EPIC Heidelberg cohort. It adds to a small but ever-growing body of science supporting the potential health benefits of vitamin K for bone, blood, skin, and now prostate health.

Simple Ways to Be Happy at Work

May 5, 2008 on 5:30 am | In Uncategorized | No Comments

happy at workTwo out of three people are dissatisfied with their jobs, according to a UK survey last year. If you belong to that two-thirds, I would urge you to do some serious reflections about your life. Because time is too short here on earth for you to spend a good portion of it doing something that makes you unhappy.

Perhaps you gave up on finding your dream job once you realized that you would never be a professional football star or a ballerina. But that doesn’t mean you have to settle for a mundane career that doesn’t excite you.

So ask yourself:

  • What would you rather be doing?
  • Is there a way for you to make a living doing something that you love and feel passionately about?
  • What are the steps to get you there?
  • What are you waiting for?

For many of you, it may simply be an emotional block — a fear of failure, perhaps — that is keeping you from going for your dream job. So you should make sure to address your emotions as you go through this process. If necessary, consult with an EFT practitioner or a life coach who can help guide you.

In the meantime, you don’t need to suffer through each day. Here are some simple tips to help you enjoy your current job:

  • Keep your work in perspective. Consider the bigger picture. Do some voluntary work to gain a broader outlook.
  • Remember that you are more than your work. Do not have your identity too strongly tied to the job you do.
  • Concentrate on the task at hand. Do not let yourself be distracted by worrying about all the other things to be done.
  • Delegate wherever appropriate. Always remember the “3D” rule — do it, dump it or delegate it — and never handle a piece of paper twice.
  • Have regular breaks. Get away from your normal workplace even if only for five minutes.
  • Switch off once you leave work. Mentally say goodbye to your workspace the moment you leave for home.
