In this episode we discuss:
The factors that affect thyroid hormone production, conversion, transport, and uptake
How high TSH levels cause damage to the thyroid gland
High-carb diets vs. low-carb diets for thyroid health
Why restricting calories is not the way to go if you’re struggling with hypothyroidism
The effects of PUFA and endotoxin on thyroid hormone activity
The problems with both deficiencies and excesses of iron, iodine, and vitamin A for thyroid health

Timestamps:
0:00 – intro
1:28 – the factors that affect thyroid hormone production, conversion, transport, and uptake
3:45 – the impact of stress on thyroid hormone production and conversion
5:02 – how the stress hormones and inflammatory cytokines affect thyroid hormone production and conversion
16:44 – thyroid hormones increase sensitivity to stress hormones
21:44 – elevated free fatty acids, especially PUFA, inhibit thyroid hormone binding
23:26 – how a lack of energy prevents the cells from taking up thyroid hormone
30:00 – how oxidative stress affects thyroid hormone production and the effects of TSH on oxidative stress
38:25 – how a low-carb diet affects thyroid hormone production and conversion, causing a hypothyroid state; high-carb diets vs. low-carb diets for thyroid health
47:46 – insulin resistance is associated with reduced thyroid hormone conversion, but this doesn’t mean you should avoid carbohydrates
51:39 – how caloric restriction affects thyroid status
55:04 – the effects of fasting on thyroid status
56:42 – T3 has positive feedback on its own production and what this means for thyroid hormone replacement
1:00:01 – the effects of PUFA and endotoxin on thyroid hormone activity
1:04:30 – the effects of micronutrients, specifically iron, vitamin A, selenium, and iodine, on thyroid hormone production, conversion, and activity
1:16:30 – increased thyroid activity increases macronutrient and micronutrient needs, but also improves micronutrient retention in the long-term
1:19:15 – the effects of environmental toxins (pesticides, industrial chemicals, heavy metals, etc.) on thyroid hormone production, conversion, and activity
1:25:20 – the effect of sleep on thyroid hormone production and conversion
