“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!
“You are what you eat” is an old expression your grandmother’s grandmother probably used, but it’s not actually correct technically speaking. Putting on my nerd hat to be a stickler for the details, it’s more accurate to say “you are what you absorb.” Grandma’s sage advice does a good job of illustrating that what we ingest is obviously essential to our health, but what we ingest that actually gets absorbed and utilized by the body is the crux of the issue truth be told.
The piles of studies that have been growing in recent years showing all manner of potential benefits of various nutrients has been very encouraging. We are experiencing an exciting time in nutritional science where new compounds are being discovered – and tested for their potential benefits – almost daily. Compounds that may help prevent cancer, improve immunity, improve weight loss, improve brain function, or improve athletic performance, to name just the tip of the iceberg of where science is currently looking to isolate and test various nutrients for their bio active properties.
How the process works:
Once a compound is discovered, it tends to get isolated, and then tested in either animal models and or in vitro (test tube) to test what positive or negative properties may exist as well as elucidate how they work. That is, understand not just what system they may impact (such as increase an animal’s ability to resist cancer causing chemicals for example) but also examine the isolated compounds’ “mechanism of action” which shows how it achieves the effect. How does that work? Let’s say some spice has been used for generations to reduce infections or improve immunity. Scientists might then feed, or inject, large amounts to lab animals (e.g., mice, rats, rabbits, etc.) and see if it does indeed have activity; perhaps testing how that spice reduces the size of tumors when the mice are exposed to known carcinogens, or bacteria known to cause infections and so forth. If that spice shows biological activity, scientists will often look deeper into that spice to see which specific constituent(s) in the spice are having the “active” compounds, and once found, will concentrate and isolate that active compound and further tests on animals, or humans, or in vitro (test tube) will continue. Foods and spices for example, are highly complex and can have hundreds or even thousands of biologically active compounds in them.

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…
As promised at the end of my vid on what doctors know about nutrition, this vid covers what most nutritionists know about nutrition.
What do Nutritionists actually know about nutrition? On the surface, it would seem they should have real expertise in the topic, but that’s not always the case. I answer why that is in this video
How do you approach it? Here’s my current thoughts on the issue:
If you want to read a much more in-depth assessment of the pre and post workout drink, read my article:
Due to the large response I received from the short video I did on the topic from people asking for more details, I decided to dedicate a show to the topic and give details on how diabetes was effectively reversed using one person as “real world” example. It can’t be done by everyone who has been diagnosed with type II – as there are genetic influences and other factors – but make no mistake, for a large % of people with type II diabetes, it can be reversed or at the very least, GREATLY improved.
This show, I use the example of one person to show how diabetes can be reversed.

Can creatine supplements reduce the calories used or slow metabolism? Some people think it does. That’s a recent question I received so I decided to answer it in this latest video.
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…
