A common Q I get is “Should I get my T levels checked Will?” When should you get your level checked? When you’re feeling tired, or lack libido or extra sore from workouts? After age 40? My answer may surprise you….
“High” Protein intakes and Cancer, is there a connection? A recent study claims it found a link between “high” protein diets and cancer rates and compares the risk to smoking! Is it true? Learn the FACTS in this video!
Will has previously mentioned DHEA as it relates to hormonal effects and health promotion:
When it comes to health promotion and longevity, DHEA is a supplement which deserves more attention than it is getting.
DHEA levels (the main circulating form of DHEA in the bloodstream is DHEAS) decrease approximately 80% between ages 25 and 75 year.[1, 2] This large decline in DHEA has led to interest in the possibility that aging related DHEA deficiency may play a role in the deterioration in physiological and metabolic functions with aging, and in the development of chronic diseases.
In support of this, it has been reported that DHEA level is negatively correlated with mortality and risk of developing cardiovascular disease (CVD) (i.e. lower DHEA(S) levels are associated with higher mortality and CVD risk).[3-5] More recently it has been found that a steep decline or extreme variability over time in DHEA(S) levels is associated with higher mortality, more so than baseline DHEA(S) levels.
Aging not only reduces DHEA(S) levels, but also results in an increase in arterial stiffness [7, 8], which is an independent predictor of cardiovascular disease (CVD) risk and mortality.[9-11] It has been reported that DHEA levels are inversely associated with arterial stiffness (i.e. lower DHEA levels are associated with increased arterial stiffness. [7, 12, 13] Therefore, it is possible that DHEA replacement could reduce arterial stiffness, and thereby contribute to reduction in CVD and mortality…
Exercise protects against heart disease in many ways. One important mechanism is by elevating HDL, a.k.a. the “good” cholesterol. It is well established that high levels of HDL are protective against cardiovascular disease and the National Cholesterol Education Program (NCEP) has emphasized increasing HDL levels to help reduce CHD risk. [2-4] However, not only HDL levels are important. Emerging research in showing that HDL quality and function is as important, if not more important for health promotion and prevention of cardiovascular and metabolic diseases…[5-7]
Synthetic sweeteners, toxic or safe? In this vid, I get to the bottom of this debate!
A hotly debated recent study, the SELECT trial, has casted doubt on the well documented health benefits of omega-3 fatty acids. This study found that a higher content of long-chain omega-3 fatty acids (EPA+DPA+DHA) in blood plasma was associated with a with a greater risk of low-grade (44%) and high-grade (71%) prostate cancers over a 5-year follow-up 1. Associations were similar for individual long-chain omega-3 fatty acids. Higher linoleic acid (omega-6) was associated with a 25% reduced risk of low-grade and 23% reduced risk of total prostate cancer 1 .
This has understandably generated confusion among the general public and intense discussions among health professionals and researchers. However, a deeper look at the data and study methodology reveals a different picture…
Will Brink and Dr Lopez have previously commented on the notorious omega-3 / prostate cancer study:
Here is my take on it…
Most everyone knows that strength training is important if you want a strong body and a nicely-muscled physique, but it’s also important for many other non-cosmetic reasons.
A study published by a German science journal pointed out the numerous benefits of strength training for aging gracefully and healthily, including: reduction of age related muscle loss, increase in muscle strength and mass (as the trainee in this story, demonstrates in the gym), reduction in the loss of bone density, and improvement in posture and coordination (which helps decrease the likelihood of falls).
Now before you start thinking: “it’s probably too late for me,” or “the gym is for muscle heads,” or “the weight room is intimidating,” I’d like you to introduce Tom, a client of mine for over 6 months, who is 76 years young.
If you’re following the health news, you know that vitamin D currently is in the media spotlight, and rightly so. Will Brink just did a great podcast “Vitamin D3 – scam or panacea?“, giving an overview on the importance vitamin D. In this article I will expand upon some key points taken up in the podcast, and back up the case with a solid reference list of recent studies on the topic. I will also present some revealing prevalence stats on vitamin D insufficiency, in order to convince you to get your blood levels checked to find out your vitamin D status.
Vitamin D is interesting for several reasons:
1. The role of vitamin D for health promotion has undergone a paradigm shift. While traditionally thought to only be important for development and maintenance of strong bones, an impressive body of scientific research has accumulated over the past decade, showing that adequate vitamin D levels are necessary to prevent many diseases, especially cardiovascular disease, high blood pressure, endothelial dysfunction, diabetes (both type-1 and type-2), the metabolic syndrome, chronic inflammation, cancer, osteoporosis (including falls and fractures), muscle weakness, cognitive dysfunction and mental illness, autoimmune diseases (e.g. multiple sclerosis, rheumatoid arthritis), infectious diseases, as well as infertility and adverse pregnancy and birth outcomes [1-24].
Vitamin D deficiency/insufficiency is associated with all-cause mortality , and supplementation has been shown to decrease mortality rates [25, 26]. It has been estimated that doubling vitamin D levels in the general population (from 21 ng/mL to 44 ng/mL) would reduce vitamin D-related disease mortality rate by 20%, and increase life expectancy with about 2 years .
2. Insufficient levels of vitamin D also have direct implications for fitness enthusiasts and athletic performance, due to the importance of vitamin D for muscle function (I will cover this in much more dept in an upcoming article) [28-39].
3. In contrast to other vitamins, vitamin D deficiency/insufficiency is very common (more on that below).
4. The vitamin D requirement for health promotion and protection against the mentioned diseases and muscle dysfunction is much higher than the dietary recommendations (RDA) for bone health [4, 40-45].
Having heard about all the vitamin D benefits you might wonder what is the optimal vitamin D level? How low is too low and how high is too high? How much vitamin D does one have to consume to reap all the benefits? Let’s find out…
Getting older doesn’t automatically preclude you from learning how to lift weights and resigning yourself to a loss of strength and functionality.
The effects of age related muscle-wasting (sarcopenia) may be counteracted by resistance training (J Strength Cond Res. 2011 Feb;25(2):326-33.), and we’re not talking about the little pink dumbbells, either. Somewhere around 60% of a maximal effort weight and higher reps, and even using free weights (not JUST the machines). For more information on the causes, prevention, and treatment for sarcopenia, there’s an extensive article on the BrinkZone HERE if interested in additional information.
Older trainees in the gym normally stick with familiar cardio machines, but if you’ve ever seen Al in action, you might want to clear some space. Al’s been a client of mine for over half a year now, and in that time he’s seen some impressive gains in strength and coordination.
Which is important when you also have Parkinson’s. He’s also in his 70’s.
Although Al’s determined personality makes our work outs fairly intense, trainees with Parkinson’s can use resistance training pretty much like everyone else. And just like anyone else, he got stronger with a basic program for resistance training.
