Do Turkey Dinners Really Make You Tired? → HERE'S WHY

The video explores why people feel tired after a Thanksgiving turkey dinner. It explains that while turkey contains tryptophan, which can convert to melatonin and cause tiredness, the main reason for post-meal fatigue is the high carbohydrate content of the meal, leading to an insulin spike. The video details the biosynthetic pathway of tryptophan to melatonin and discusses how insulin affects nutrient absorption, allowing more tryptophan to be converted into melatonin.

What is the primary amino acid found in turkey that is often associated with making people feel tired?

• Glutamine

• Lysine

• Valine

• Tryptophan

What is one of the main reasons for feeling tired after a Thanksgiving meal, according to the video?

• Lack of fiber

• High protein content

• High carbohydrate content

• Excessive salt

Which enzyme is responsible for the decarboxylation of tryptophan in the biosynthetic pathway?

• Aromatic amino acid decarboxylase

• Serotonin transferase

• Hydroxylase

• Melatonin synthase

What is the final product in the biosynthetic pathway from tryptophan that contributes to sleepiness?

• Serotonin

• Melatonin

• Dopamine

• Adrenaline

How does insulin affect the absorption of tryptophan into the blood?

• It increases the absorption

• It decreases the absorption

• It has no effect

• It blocks the absorption

Why is it beneficial that Thanksgiving dinner contains a lot of glucose?

• It helps in the digestion of proteins

• It enhances the taste of the meal

• It increases the absorption of tryptophan

• It reduces the feeling of fullness

What role does insulin play in the context of Thanksgiving dinner and tiredness?

• It blocks tryptophan absorption

• It helps in nutrient absorption and reduces amino acid competition

• It only causes a sugar crash

• It increases serotonin production directly
