Frequent consumption of red and processed meat has been shown in population studies to be positively correlated with cardiovascular disease [1-3], cancer and type 2 diabetes. Recent meta-analyses also indicate that it increases total mortality . Hence, a high meat intake (regardless of its fat quantity and quality) is generally perceived to be unhealthy and something that should be avoided. However, although there are many studies documenting these associations, results are not always consistent and there are several methodological issues which weakens the strength of their findings (more on that in a bit). In the same way as the putative health risks of red meat consumption is investigated, its documented health benefits (which I will cover below) are equally as important and must be given a fair chance in the establishment of public health messages in relation to red meat consumption. In this article I will therefore cover both the risks and benefits associated with red meat consumption, and after having taken all the scientific data into consideration, argue that meat has been unfairly blamed…
“Bulletproof coffee” has become a popular addition to some people’s diets, but is it all its claimed to be? I answer that Q in this vid!
In a previous post I outlined the U-shaped relationship between IGF-1 and all-cause mortality.
A growing body of research shows that IGF-1 has a U-shaped relationship with other health outcomes as well, including cancer. This may come as a surprise, as IGF-1 is well-known to increase cancer risk…
IGF-1 (insulin-like growth factor-1) is a peptide hormone, produced predominantly by the liver in response to pituitary GH (growth hormone). IGF-1 is involved in a wide variety of physiological processes. In adults, IGF-1 has metabolic and anabolic effects, and it mediates many of the effects of GH.[2-4]
GH and IGF-1 levels are reduced with normal aging, a phenomenon called somatopause.[5-7] It has been suggested that somatopause is an age-related GH deficiency state. Somatopause has been considered to contribute to physiological deterioration seen with aging, like reduced muscle mass, reduced exercise tolerance, decreased strength, osteoporosis, increased fat mass, elevated cardiovascular risk, impaired quality of life, cognitive/memory decline and reduced immunity.[7-12] These changes are similar to those seen in classic (non-aging related) GH deficiency (GHD).[13, 14]
EDITORS NOTE: I (Will) recently did a video on ARA which discusses a recent study that found ARA had positive effects on strength and muscle mass readers will want to check out. The results of this study will be covered in a future article by Monica when the study is published. This excellent article below by Monica discusses the long held belief this fatty acid is a negative for health and well being. As usual, the truth turns out to be more complex and a read of this article will cover the studies to demonstrate that. Part II of this article can be found HERE.
It is well known that the typical American diet provides too little omega-3 and too much omega-6, and thus has an elevated omega-6/omega-3 ratio. In turn, an elevated omega-6/omega-3 ratio has been linked to a number of common chronic diseases, notably cardiovascular diseases, inflammatory diseases, cancer, and certain psychiatric diseases such as depression.[1-3] The omega-6 fatty acid that has been vilified and blamed to give rise to these detrimental health outcomes is arachidonic acid (ARA).
However, a deeper look at the research data reveals that the association between omega-6 fats, especially ARA, with detrimental health outcomes isn’t as clear-cut as previously thought. Prominent lipid researchers are even questioning the value of the conceptually entrenched omega-6/omega-3 ratio. And there are indications that ARA, previously thought to be the omega-6 villain, actually may confer health benefits and even increase muscle mass and strength when combined with resistance training…in this 3-part series you will find out about it all…
Yes, literally, and could save other children from a lifetime of ill health easily avoided. Genetic disorders effect millions of children, and there’s 29 currently screened for by simple blood test, but not the one this baby and others suffer from. Some children have been mistakenly diagnosed with Cerebral Palsy (and likely other disorders) when in fact it was an easily treatable disorder known as GAMT deficiency or simply “creatine deficiency disorder.” GAMT deficiency, which can be tested for easily, has some researchers pushing for newborn screening that would use the same blood test that screens for 29 recommended disorders. Without early intervention, brain damage can be permanent, so it must be caught early.
This recent story really brings home how this inexpensive non-toxic nutritional supplement could be a life saver for children with this easily testable genetic disorder:
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….
Many know Red meat has a reputation for being superior for building muscle, and has for thousands of years, but is it true? I attempt to cover that issue in this vid!
Health Concerns over red meat? See: Red Meat and Health – have we been blaming the wrong thing?

Very limited data suggest that meat consumption by older people may promote skeletal muscle hypertrophy in response to resistance training (RT).
The objective of this study was to assess whether the consumption of an omnivorous (meat-containing) diet would influence RT-induced changes in whole-body composition and skeletal muscle size in older men compared with a lactoovovegetarian (LOV) (meat-free) diet.
Nineteen men aged 51-69 y participated in the study. During a 12-wk period of RT, 9 men consumed their habitual omnivorous diets, which provided approximately 50% of total dietary protein from meat sources (beef, poultry, pork, and fish) (mixed-diet group). Another 10 men were counseled to self-select an LOV diet (LOV-diet group).
Maximal strength of the upper- and lower-body muscle groups that were exercised during RT increased by 10-38% (P < 0.001), independent of diet. The RT-induced changes in whole-body composition and skeletal muscle size differed significantly between the mixed- and LOV-diet groups (time-by-group interactions, P < 0. 05). With RT, whole-body density, fat-free mass, and whole-body muscle mass increased in the mixed diet group but decreased in the LOV- diet group. Type II muscle fiber area of the vastus lateralis muscle increased with RT for all men combined (P < 0.01), and the increase tended to be greater in the mixed-diet group (16.2 +/- 4.4 %) than in the LOV diet group (7.3 +/- 5.1%). Type I fiber area was unchanged with RT in both diet groups.
Consumption of a meat-containing diet contributed to greater gains in fat-free mass and skeletal muscle mass with RT in older men than did an LOV diet.
“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!
