Excess Protein and Fat Storage – Q&A
Which means that the odds of protein being converted to fat in any quantitatively meaningful fashion is simply not going to happen. Certain amino acids are processed to a great degree in the liver (as I discuss in The Protein Book) and this can produce glucose, ketones and a few other things. But triglycerides (the storage form of ‘fat’) isn’t one of them.
A Quick Look at Food Allergies and Intolerances
In recent year, a lot of ideas have become strangely popular on this place that we call the Internets, one of those is concern over various food allergies and intolerances . As I’ll discuss below, not only are true food allergies and intolerance two totally different things, there is a lot of nonsensical information being thrown around about food allergies.
Fish Intake and Mercury
A question that comes up often enough to be worth addressing is just how much fish can be consumed on a daily basis to get the benefits of it as a protein source while avoiding potential issues with mercury. To address this, I’m simply going to excerpt the bit from Chapter 10 of The Protein Book where I examine fish protein and the issue of mercury content.
What Are Good Sources of Protein? – Wrapping it Up
In What Are Good Sources of Protein – Introduction, I included a short list of other important factors such as effects on appetite and blood sugar that I already addressed in previous parts of this series so I won’t touch on them here. The issues I do want to touch on are availability, the actual protein content, and cost.
What Are Good Sources of Protein? – Dietary Fat Content
As with the issue of micro-nutrients, the presence or absence of dietary fat (either in terms of the quantity or quality) can impact on the choice of protein source. And this actually turns out to be a place where dietary fat content can vary massively, not only between protein sources but between different sources of the same protein.
What Are Good Sources of Protein? – Micronutrient Content
Today I want to look at an issue that I don’t think is addressed as much as it could be when folks are looking at protein source; that topic is the presence (or absence) of other nutrients. Outside of a few select groups (that often get a majority of their protein from isolated sources such as protein powders or amino acids), the fact is that most people get their daily protein from whole food sources and whole foods contain other nutrients. Some of those nutrients may be beneficial, some of them may be detrimental; all need to be considered when look at protein sources.
What Are Good Sources of Protein? – Amino Acid Profile Part 3
Although there are certainly other adaptations occurring to training (e.g. neural, cardiovascular), one of the primary places where adaptation to regular training occurs in skeletal muscle. Both endurance training and heavy resistance training stimulate specific adaptations in skeletal muscle that work to improve performance in the long run.
What Are Good Sources of Protein? – Amino Acid Profile Part 2
There are a number of different ways by which by which exercise training might increase protein/amino acids requirements. This includes the use of amino acids for energy directly during exercise, other pathways of interest (see below), and finally the actual adaptation to training. I also want to touch briefly on the issue of dieting.
What Are Good Sources of Protein? – Amino Acid Profile Part 1
Now, as I’ve mentioned but not gone into any great detail in this series, amino acids are simply the building blocks of protein. Depending on which reference source you use, there are 18-22 different amino acids that occur in the human food supply. Whole food proteins are simply long chains of these amino acids bonded together. Typically whole food proteins are extremely long chains of amino acids, as I discussed in What are good sources of protein? – Digestibility, these long chains are cut into smaller and smaller chunks during digestion until only single amino acids and chains of 2-3 amino acids are actually absorbed.
What Are Good Sources of Protein? – Protein Quality
Essentially, protein quality simply refers to how well or how poorly a given protein is used by the body once it has been digested. Clearly, any protein that escapes digestion (as discussed in What are good sources of protein? – Digestibility) can’t do anything in the body but that doesn’t mean that all of the protein that is digested automatically works the same in the body.
