The Food Revolution is Coming! Time to Rethink Your Diet?

Posted on May 8, 2012 by Dr. P.K. Newby Posted in General Health, Healthy Eating, Nutrition Leave a comment

Screen Shot 2012 05 08 at 10.59.26 AM Have you ever heard of Food Revolution, the tv show hosted by Jamie Oliver? Well, it’s more than just a television program, it’s a global event coming up on Saturday, May 19. For more about its mission and to see Jamie’s video call to action, click here.

Of course, I’m getting pretty excited about this “holiday” – in my own science geek-nutrition nerd-foodie kind of way – and even if May 19 is just a regular day for you, perhaps it’s a good time for you to rethink your diet. And guess what? It’s not just about weight. Even if you’re at an ideal body weight, that doesn’t necessarily mean you’re eating the way you should for long-term health and longevity. Having a lean physique isn’t equivalent to being metabolically fit, either, something SIF readers know quite well. Moreover, what we eat matters for many reasons beyond your own personal health, which is one of the themes addressed on my blog, Play a Good Knife and Fork.

All that said, as a nutrition scientist with expertise in obesity and chronic disease prevention, of course the way I cook and eat is designed to maximize your own health in the tastiest way possible. So, as we sail towards the summer, I thought this would be a good time to direct you to a few of my posts from January dedicated to rethinking your diet as well as your approach to food and nutrition. The times feel rather similar in some ways, don’t they? In January, most of us make new year’s resolutions to lose weight and get in better shape. In April and May, many of us are again – or still – thinking about weight as the warmer weather and its smaller-sized clothing looms ever nearer. (So long for now, bulky sweaters and boots!) Combined with the increased summer socializing that inevitably seems to lead to more eating and drinking, now is a great time to “spring your diet into shape.” (Yeah, maybe not, but you know what I mean.) 

To get started, I invite you to read the first short introductory piece in the series, Recalibrating Your Diet: Weight Loss and Beyond. This article seemed even more appropriate upon rereading it today since it has a Joss Whedon (The Avengers) reference in it, in case any of you are fans…

Vitamin B12 Deficiency linked to Memory Problems

Posted on September 27, 2011 by Matt Posted in Health in the News, Nutrition 3 Comments

vitamin b12 [cnn.com] There’s been a lot of buzz about vitamin B12 in recent years, and here’s another reason to pay attention to it:

A new study finds that a deficiency in vitamin B12 is associated with memory and thinking problems, as well as brain shrinkage. The research is published in the journal Neurology.

Researchers did not prove that low vitamin B12 levels cause these cognitive abnormalities, but they did find a strong association with markers of deficiency, said study co-author Dr. Martha Morris of the Rush University Medical Center in Chicago.

The theory is that adequate levels of vitamin B12 is necessary for the brain’s myelin sheath, an insulating layer around nerves. When the sheath gets damaged, impulses between transmitted along nerve cells slow down.

Vitamin B12 is found in meats, fish, shellfish and dairy products, and some cereals are fortified with it. People over 65 in particular may need B12 supplements because older patients’ bodies have a harder time absorbing this vitamin.

Researchers looked at 121 participants in the Chicago Health and Aging Project. They looked at both serum levels of vitamin B12 and markers of vitamin B12 deficiency.

The study found that methylmalonate, a marker of vitamin B12 deficiency, is associated with a reduction of brain volume and so may contribute to cognitive problems. Homocysteine, an amino acid associated with low B12 levels as well as folate, was linked to thinking problems through a different mechanism involving abnormal white matter signals (as seen on certain kinds of MRIs).

There aren’t a lot of data on using these markers clinically for the purposes of testing the health of older patients, said Dr. James Lah, neurologist at the Emory University School of Medicine in Atlanta, Georgia, who was not involved in the study. The study points to them as potentially helpful, but more research needs to be done, he said.

The study did not find an association between the serum B12 levels of participants and the likelihood of brain problems. Morris said that makes sense because while low levels negatively affect the brain, high levels above normal aren’t necessarily better than adequate levels.

“There’s a level we should all have, and if you fall below that, it could cause problems,” she said.

Quantifying that level is up for debate, but the National Institutes of Health offers  guidelines for recommended vitamin B12 intake at various ages.

Morris and colleagues did not look at this phenomenon in Alzheimer’s patients, but a small 2010 study in Neurology found that people who tended to eat vitamin B12-rich foods are less likely to develop Alzheimer’s than those who did not. Vitamin B12 deficiency has not been shown to be directly involved in the pathology of Alzheimer’s in the brain, but it may aggravate the brain in other ways that could lead to Alzheimer’s. “We can’t discount its involvement,” Lah said.

Top Vegetarian Protein Sources

Posted on April 20, 2011 by Matt Posted in Nutrition Leave a comment

Protein is essential to human health and if you are trying to gain muscle then it is absolutely imperative. Even with a vegetarian lifestyle there are still plenty of ways to get the adequate amount of protein your body needs. Here are some of our recommendations:

Beans, Lentils and Legumes

 

 3f54cad5d593cab6788e9532c1af5939

There are many great options in this group. Choose what you like most, black, lentil, kidney, garbanzo, pinto, chickpea, etc and add it to your salad, grain, or have it as a side dish. Vegetarian chili with a mix of all your favorite beans is a great way make a delicious meal out of it. You can also mash up some chickpeas and make hummus for a healthy snack. Most beans range from 10 grams up to 20 grams of protein in a cup. Beans are also high in iron, fiber, and Vitamin B. Just be careful if you are on a low-carb diet as they are high in carbohydrates.

Soy

 

 fc2882a3e36240e95744576d7ef7c1df

There are endless possibilities in this category. Tofu contains 20 grams of protein in one cup. This is a perfect meat alternative. It is best to use extra firm tofu as it has been pressed the longest so contains the most protein and least amount of carbs. Also give soy milk (7 grams protein per cup) a try, you may be surprised with how much you like it. One of my favorites is edamame, which I buy frozen from Costco so I always have it on hand. One cup contains 28 grams of protein, equal to a 3-ounce steak! There are many other soy products you can experiment with, such as cheese, miso, yogurt, ice cream, and tempeh. Tempeh is a fermented soybean that you may not have heard of. It has about 19 grams of protein and is also a great source for fiber, iron, potassium, B12 and calcium. Look for it next time your at your local market!

Nuts & Seeds

 

 c6af2d472e0e39c095b8b8a82d37557a

These are great for a small snack option. Nuts however are also high in fat so make sure you are watching your serving size. Almonds aka “The King of Nuts” have about 8 grams protein in ¼ cup. Sunflower seeds are filled with potassium, contain 6 grams of protein (in ¼ cup) and help reduce sodium in your body. Top your salad with them for a nutritious crunch!

Veggie Patties

 

 dfec2188aa78ee34999a3edb7ac66a5c

Even meat lovers should give veggie patties a chance.  Morningstar patties provide 10 grams of protein with only 100 calories and 3 grams of fat. Replace your beef for this healthy alternative next time you’re grilling out, just make sure it’s sandwiched on a whole-wheat bun! The patties are also great to add to your salad to get that extra protein that you need.

Protein Supplements

 

 8be55148f0dd1dee2b5d54f2d4f5d4f6

Add protein to your smoothies or even your yogurt for an extra punch.  I buy whey protein in bulk to keep the cost down but it is something I can’t live without.  My standard post-workout drink consists of milk, protein, peanut butter, a banana, a little cocoa powder and it’s fantastic! You can also add protein when baking muffins, cookies, etc. There are also many options for protein supplements so read the labels and choose what’s best for you and your dietary needs.

Grains

 

 77add461c6ea38a90f576ec63123f802

Quinoa has become a staple in my house. Whole grains in general are a great source of protein but quinoa, which is known as the “complete protein,” packs in about twice as much. Quinoa is also one of very few non-meat “complete” proteins, meaning that it contains all nine essential amino acids. One cup of cooked quinoa is packed with 8 grams of protein and 9 grams of fiber.  The body absorbs grains slowly so grains provide us high quality energy to get us through our busy days.

Green Vegetables

 

 7dcab9e968a94829d0e80384d013e732

These veggies don’t pack quite the protein punch that the options above to but you still get a decent amount of plant-based protein from them.  Spinach, kale, collards, and other leafy greens have about 5 grams per cup.  Always remember when choosing your leafy greens, the darker the more nutrients packed in. Broccoli, brussel sprouts, and asparagus contain about 6 grams per cup.

The Problem With “Celebrity Trainers”

Posted on March 23, 2011 by Matt Posted in Celebrities, General Health 3 Comments

article 1245516 07DBA5E5000005DC 732 468x6591

The fit skinny Tracy Anderson walking with celebrity client, Madonna.  The “best exercise genius of all time” lacks muscle tone, but makes up for it in the skin-and-bones department.

Have you ever wondered what makes one trainer better than another?  Why is Jillian Michaels so popular right now?  Is it because she is so much better than everyone else out there?  Why do trainers to the stars command a higher hourly rate than most doctors and lawyers do?  Are they really that good and worth the $400/hr price tag?  Common sense, says no.

Plenty of websites tout their stable of celebrity trainers; Exercise TV comes to mind.  They are hoping to sell you on the big names and pretty faces, NOT on the quality of the workout.  Having 20 different famous fitness trainers is all well and good, but are you really getting a better workout?  Does the fact your trainer has their face on 5 different magazines this week mean the squats she/he is having you do are burning more calories or building more muscle?  Of course not.

Lets take a look at trainer to the stars, Tracy Anderson.  She works closely with Gwyneth Paltrow, among others, to help her maintain her Hollywood figure.  Paltrow stated about Anderson, “she’s a pint-sized miracle and the exercise genius of all time”.  Now, with these quotes splashed across US weekly and the like, millions of impressionable readers start thinking that Tracy Anderson and her workouts are the real deal.

The problem is, these workouts from these so-called fitness experts are designed to make you lose weight fast and in a very unhealthy manner.  When ordinary people try to go on these workout programs, they sacrifice far too much in the name of weight loss.  Take for example the following excerpts from an article written by the very average, size-12, Rebecca Wilcox:

“So I bought into the Tracy Anderson Method, got hold of her DVDs and books, and ordered her latest boxed set Metamorphosis: A Complete Body Transforming System, a 90-day programme you graduate to after completing the 30-Day method, and which is available only from Tracy’s website”

“I have to say, Gwyneth made it look rather too easy. On the 30-Day Method you have to do to three hours of exercise a day, which decreases to one hour on the 90-day plan.”

“It basically involves doing jazzy leaps, star jumps and aerobic moves in my living room.  Tracy is totally against other forms of cardio, such as running, where you repeat your movements over and over. That, she says, will bulk muscles. Along with the aerobics you must do a series of 40 toning Pilates-style moves, which change every ten days. It is gruelling and also mind-numbingly boring. I find myself staring at pictures of Gwyneth in her bikini for ‘thinspiration’.”

“On the downside I feel woozy and find it difficult to concentrate. At first I had loads of energy but now I’m always tired and am told I’m horribly grouchy to boot.  My skin is terrible and my nails are flaking and weak. And  -  how can I put this  -  my system has become, shall we say, somewhat sluggish. Normally I’m as regular as clockwork. Not any more.”

For the full story check out the link: http://www.dailymail.co.uk/health/article-1367879/Gwyneth-Paltrows-personal-trainer-Tracy-Andersons-diet-plan-gave-blackouts.html

So, as the story illustrates, these type of workouts and trainers aren’t always the best.  Of course this is only one individual experience, and it doesn’t “prove” anything.  It does however, hopefully begin to open peoples’ eyes to the unhealthy and risky workout and diet plans these celebrity trainers are feeding us.  Further, these workouts aren’t even engaging.  If some Joe on the corner told you to do calisthenics for 3 hours a day and eat little to no carbs, you’d better believe you’d lose weight.  Does that make Joe a great trainer?

A great trainer and/or training website is one that seamlessly makes fitness a part of your life and something you can incorporate into your lifestyle for a significant period of time.  Crash diets and insane workout plans may work a bit faster, but will leave you miserable while you are on them and crushed when the weight comes back as soon as you go off their strict schedules.

The problem with celebrity trainers is the fact they are themselves a business.  Their goal is to make money, and I’m not going to fault them for that.  However, you need to be aware that they are in this to make money.  If these trainers had a solid plan for losing weight, why are they coming out with a new way to burn fat every few months?  Answer: because they know people will buy whatever they are selling.  Be smarter than this and don’t buy into their junk.

Something else to keep in mind; a large proportion of these “expert” celebrity trainers have no educational background in fitness.  Many have never seen the inside of a college classroom.  A trainer with advanced kinesiology degrees and 10 years practical experience is going to be better qualified and more knowledgeable than any trainer on the cover of some magazine.

This is what Share It Fitness was built on.  We’ve spent (and still are) a great deal of time trying to find the best of the best to create video workouts for us. Our instructors’ workouts are built on practical experience in a gym and educational backgrounds that have provided our trainers the depth of knowledge required to create effective workout routines that you will actually stick with.  That doesn’t mean they aren’t intense, it just means they know how to incorporate their training methods quite seamlessly into your everyday life.  Remember, anyone can tell you to workout three hours a day and starve yourself, and you will undoubtedly lose weight.  That doesn’t make them a good trainer.  Good trainers work with you and figure out the best way to attack your specific goals.  Nothing is uniform at Share It Fitness; our workout plans are different for each individual that visits our site. Next time you see some brand new celebrity workout that you are considering, remember this: generic workout plans from these so-called ”experts” are seldom the answer to lifelong health and fitness.
