It seems there’s a lot of conflicting advice about whether pregnant women should eat fish, or avoid it due to concerns over high mercury levels. What do you think?
The concern is real. Pregnant women should not eat fish that are high in mercury. It is also good to rotate and eat different types of fish in your diet.
1. Which fish in this “Watch Out list” contains the highest mercury levels?
b. King Mackerel
2. Of the fish listed here, which have the highest concentrations of Omega 3 Fatty Acids?

What is the “stress hormone” cortisol, and how does it affect our bodies?
Cortisol is your “stress response hormone.” Your body secretes it in response to physical or emotional stress. It prepares your body to meet physical or emotional challenges by increasing your heart rate, blood pressure and level of alertness. It helps us defend against an “attack.” While cortisol is a survival hormone, chronic stress creates a high level of this ‘fight or flight’ hormone, which causes undesirable mental and physical effects. It engenders survival instincts–quick decisions based on minimal analysis. Sharp strategic thinking ability is impaired. Caffeine is a major stimulator of cortisol secretion. Too much caffeine might make you more alert but not a smarter thinker! Insulin–secreted in response to cortisol–causes sugars (from ingested carbohydrates) to move out of our blood stream and stored in the form of fat–increasing overall body fat and weight. As blood sugar levels decline, ‘brain fog’ ensues.
