Food goes in Food is stored, mixed, emptied
Food is digested and absorbed
Food is excreted
Digestion

Nutrition Basics:The Breakdown of Nutrients
• Simple sugars are quickly absorbed Glucose is sent to the liver, used for energy or
transformed into fat• Complex carbohydrate digest more slowly Gradually become glucose
• Protein is broken down into amino acids Sent to the liver, then on to support muscles, or
changed into glucose for energy, and then to fat for storage
• Fat is absorbed slowly as fatty acids Absorption requires very little digestive energy
![Page 10: Can Food Affect My Mood? Jodi Bjurman, RD, CDE Outpatient Dietitian El Camino Hospital.](https://reader035.fdocuments.us/reader035/viewer/2022070306/551921e455034642428b4b90/html5/thumbnails/10.jpg)
From the gut to the brain
• Blood brain barrier Nutrients absorbed into
blood stream Carried to brain Cross blood brain barrier Used to activate or
create neurotransmitters Neurotransmitters affect
brain function Brain function affects
mood

Chemical Where? Influence?
Cholecystokinin GI tract food intake
Neuropeptide Y Hypothalamus carb intake
Insulin Pancreas food intake
Glucagon Pancreas food intake
Cortisol Adrenal glands fat intake
Progesterone + Estrogen
Ovaries food intake
Serotonin Brain Low - carb intake; High - carb intake
Dopamine Brain Inhibits appetite

Adapted from Food and Mood by Elizabeth Somer, 2nd Edition
Chemicals that influence eating – to name a few

Serotonin
Carb rich snack
Insulin secreted
Blood levels of amino acids (except tryptophan) drop
Tryptophan high in blood, readily enters brain
Tryptophan converts to serotonin
Serotonin levels rise and mood improves, carb cravings subside
Adapted from Food and Mood by Elizabeth Somer, 2nd Edition
![Page 14: Can Food Affect My Mood? Jodi Bjurman, RD, CDE Outpatient Dietitian El Camino Hospital.](https://reader035.fdocuments.us/reader035/viewer/2022070306/551921e455034642428b4b90/html5/thumbnails/14.jpg)
SerotoninEat protein-rich meal/snack
Blood levels of amino acids rise (including tryptophan)
Amino acids compete for entry to brain
Very little tryptophan gets in
Very little serotonin is made
Person feels depressed, irritable, craves carbs
Adapted from Food and Mood by Elizabeth Somer, 2nd Edition
![Page 15: Can Food Affect My Mood? Jodi Bjurman, RD, CDE Outpatient Dietitian El Camino Hospital.](https://reader035.fdocuments.us/reader035/viewer/2022070306/551921e455034642428b4b90/html5/thumbnails/15.jpg)
Dopamine/NorepinephrineProtein-rich snack
Levels of tyrosine in blood increases
Levels of tyrosine in brain increase
Tyrosine increases conversion of Dopa to Dopamine
Dopamine converted to norepinephrine via Vit C
A person feels more energetic and clear-headed

Acetylcholine
Choline from diet or supplement
Blood choline levels rise
Brain choline levels rise
The brain makes acetylcholine
Thinking and memory improve

Neuropeptide Y (NPY)
Glycogen stores are low
Blood-sugar levels drop
Brain register low blood sugar and
sends message to hypothalamus
Hypothalamus releases NPY
Desire for carbs increases and carbohydrate is eaten
Adapted from Food and Mood by Elizabeth Somer, 2nd Edition
NPY levels drop
![Page 19: Can Food Affect My Mood? Jodi Bjurman, RD, CDE Outpatient Dietitian El Camino Hospital.](https://reader035.fdocuments.us/reader035/viewer/2022070306/551921e455034642428b4b90/html5/thumbnails/19.jpg)
Galanin
Person follows restrictive diet or woman’s estrogen levels rise during menstruation or pregnancy
Galanin is released from the hypothalamus
A person desires and consumes fatty foods
Galanin levels drop

Carbohydrates and Mood
• Increase serotonin levels
People feel “happier”, “calm”, and “satisfied”

Protein and Mood
• Essential for normal development of nerve system• Many neurotransmitters are composed of amino
acids or choline (fat-like substance)• Consume too little Body limits neurotransmitter production Person experiences changes in mood, appetite,
and thinking
![Page 23: Can Food Affect My Mood? Jodi Bjurman, RD, CDE Outpatient Dietitian El Camino Hospital.](https://reader035.fdocuments.us/reader035/viewer/2022070306/551921e455034642428b4b90/html5/thumbnails/23.jpg)
Fat and Mood
• Increases transit time through the GI tract• Helps initiate feelings of fullness Cholecystokinin secreted when bowel senses fat,
closes pylorus, stomach fills, hunger suppressed• Enhances flavors, aromas, textures Craving sweets or salt? Probably craving fat too…
• Omega-3 fatty acids linked to mood enhancement• Survival instincts drive desire for fat

Micronutrients
• Key in the development of the nervous system
• Essential for neurotransmitters
Assist with manufacture of neurotransmitters Aid in neurotransmitter activity Protect them from damage
• Over- and under- consumption have negative consequences
Can contribute to depression, irritability, food cravings, mood swings, and thinking problems
