Seasonal Allergies? Think About the Histamine in Your Food | Chris Masterjohn Lite #68 Sep 13, 2018

Show notes

If you suffer from allergies, you may need to remove fermented, aged, and cured foods from your diet. While the ultimate solution should be to make yourself more resilient to both pollen and these foods, lowering the amount of histamine in your "histamine bucket" may provide needed relief in the short-term.

When Measuring Your Waist Circumference Doesn't Work | Chris Masterjohn Lite #67 Sep 11, 2018

Show notes

In the past I have recommended measuring your waist circumference in addition to your scale weight when you are trying to lose weight or gain muscle. This is an easy way to gauge how much of your change in weight is fat versus muscle.

But sometimes it just doesn't give you good information. Waist circumference is influenced not just by abdominal fat but also by the amount of undigested food in the stomach, and by retention of water and gas from hormones, inflammation, and digestive distress. This episode is about how to tell when you should and shouldn't be measuring your waist circumference.

Why You Shouldn't Manage Iron Overload With Diet | Chris Masterjohn Lite #66 Sep 06, 2018

Show notes

It may seem that people at risk of iron overload should manage it by avoiding iron-rich foods, but in most cases this is a bad idea. Iron-rich foods are rich in many other nutrients, like copper, zinc, vitamin A, and vitamin B12. Chelators like phytate can induce deficiencies of other minerals, like zinc. In this video, I explain why dietary management should be a last resort for iron overload.

Why You Probably Don't Need to Care About Avoiding Iron-Rich Foods | Chris Masterjohn Lite #65 Sep 04, 2018

Show notes

A lot of people seem to think that they should avoid iron-rich foods, even if they have no reason to believe they have a genetic predisposition to iron overload. In this video, I show you why this is ridiculous. I *do* have a genetic predisposition to iron overload, and I consume over 5 times the daily value for iron, including 10 ounces of red meat, and my iron status is kept on the low end of the physiologically healthy range by donating blood about once a year. Watch the video to see the numbers!

In the video, I reference this previous episode on looking up your genetics for iron overload: https://chrismasterjohnphd.com/2017/03/22/know-youre-risk-iron-overload/

Show notes

In this episode, I break down an iron panel and explain why it's important to also measure serum ferritin and transferrin, and when you should use transferrin saturation instead of iron saturation as a marker of your short-term iron status.

How to Monitor Your Thiamin (Vitamin B1) Status | Chris Masterjohn Lite #63 Aug 28, 2018

Show notes

Thiamin, or vitamin B1, is needed for energy metabolism but is especially important to carbohydrate metabolism. Its deficiency causes severe neurological problems, but moderate deficits may manifest more mildly as poor carbohydrate tolerance. Carnivores and vegans alike can get plenty of thiamin if they eat the right foods, but a diet based mainly on fat, or on refined foods that have not been fortified with thiamin, can cause deficiency. Nevertheless, thiamin is unusual in that most factors contributing to deficiency are not dietary, and many are actually environmental. In this video, I teach you how to assess your thiamin status and fix it if you have a problem.

The Best Way to Supplement With Potassium | Chris Masterjohn Lite #59 Aug 14, 2018

Show notes

Only 2% of Americans meet the official recommendations for potassium, yet potassium supplements carry risks that has led the FDA to strictly regulate the amount in one serving to be so small you would need to take 50 pills a day to meet the requirement. Here are my recommendations for using potassium citrate powder in a way that protects you from the risks and allows you to get the benefits of much larger amounts than found in the typical pills.

The potassium citrate powder discussed in the video can be found at https://chrismasterjohnphd.com/potassium. If you use my affiliate link, I will earn a small commission at no extra cost to you.

Please make sure to watch the video for proper use of the supplement and clear the decision with your doctor in case you have any conditions or are on any medications that impair your ability to handle potassium supplements.
