2Depression is a state of low mood and aversion to activity can have a negative effect on a person's thoughts, behavior, feelings, world view and physical well-being
3Depressed mood is not necessarily a psychiatric disorder. It is a normal reaction to certain life events, a symptom of some medical conditions and a side effect of some medical treatments.Depressed mood is also a primary or associated feature of certain psychiatric syndromes such as clinical depression.
4What causes Depression? Family HistoryHaving a family members who has depression may increase a person’s riskImbalances of certain chemicals in the brain may lead to depression
5Major Life ChangesPositive or negative events can trigger depression. Examples include the death of a loved one or a promotion.menopause, financial difficulties, job problems, relationship troubles, separation and bereavementMajor Illnesses such as heart attack, stroke or cancer may trigger depression.
6Certain medications used alone or in combination can cause side effects much like the symptoms of depression.Use of Alcohol or other Drugs can lead to or worsen depression.Depression can also occur for no apparent reason!
7Symptoms of Depression Vary from person to person2 key signs areloss of interest in things you like to dosadness or irritability
8Additional Signs include: Changes in feelings which may include:Feeling emptyInability to enjoy anythingHopelessnessLoss of sexual desireLoss of warm feelings for family or friendsFeelings of self blame or guiltLoss of self esteemInexplicable crying spells, sadness or irritability
9Changes in behavior and attitude These may include:General slowing downNeglect of responsibilities and appearancePoor memoryInability to concentrateSuicidal thoughts, feelings or behaviorsDifficulty making decisions
10Physical Complaints These may include: Sleep disturbances such as early morning waking, sleeping too much or insomniaLack of energyLoss of appetiteWeight loss or gainUnexplained headaches or backachesStomachaches, indigestion or changes in bowl habits
11Major Depression This type causes symptoms that may: Begin suddenly, possibly triggered by a loss, crisis or changeInterfere with normal functioningContinue for months or yearsIt is possible for a person to have only one episode of major depression. It is more common for episodes to be long lasting or to occur several times during a person’s life
12Dysthymia People with this illness are mildly depressed for years. They function fairly well on a daily basis but their relationships suffer over time.
13Bipolar DisorderPeople with this type of illness change back and forth between periods of depression and periods of mania (an extreme high).Symptoms of mania may include:Less need for sleepOverconfidenceRacing thoughtsReckless behaviorIncreased energyMood changes are usually gradual,but can be sudden
14Season Affective Disorder This is a depression that results from changes in the season.Most cases begin in the fall or winter, or when there is a decrease in sunlight.
15Professional treatment is necessary for all these types of depression.
16Treatment for Depression MedicationAntidepressants can help ease the symptoms of depression and return a person to normal functioning. Antidepressants are not habit forming.
17PsychotherapyThis can help many depressed people understand themselves and cope with their problems. For example:Interpersonal therapy works to change relationships that affect depressionCognitive-behavioral therapy helps people change negative thinking and behavior patterns
19NeurotransmittersΑre types of hormones in the brain that transmit information from one neuron to another.Neurotransmitters control major body functionsincluding movement,emotional response, and the physical ability to experience pleasure and pain.The most familiar neurotransmitters which are thought to play a role in mood regulation are serotonin, norepinephrine, dopamine, acetylcholine, and GABA.
20NeurotransmitterEffects on Mental Health: · Modulate mood and thought processes · Control ability to focus, concentrate, and remember things · Control the appetite center of the brain · Regulate sleep
21SerotoninSerotonin is an inhibitory neurotransmitter involved in the regulation ofmood, anxiety, libido, compulsivity,headaches, aggression, body temperature,eating disorders, social anxiety, phobias,sleep, appetite, memory and learning,cardiovascular function, muscle contraction, and endocrine regulation.Proper amounts of circulating serotonin promote relaxation.Stress reduces our serotonin levels as our body uses up serotonin in an attempt to calm itself.
22Serotonin is created in the brain in a long series of reactions involving a precursor compound, 5-hydroxy-tryptophan or 5-HTP, and a methyl donor, S-adenosyl methionine or SAMeThe concentrations of these compounds can affect the synthesis of serotonin.By increasing the synthesis, it may be possible to increase the concentration of serotonin in the brain.
23Serotonin Proteins and healthy fats are pro-serotonin foods while things like caffeine, soda, coffee, fake sugars, and processed foods are all anti-serotonin foods.Our serotonin levels become depleted when we are not consuming a balanced diet.A low-calorie, low-fat, low-carb, or low-protein diet can significantly alter our serotonin levels and affect our mood
24Tryptophan is an essential protein that we must obtain from the diet. It is found in high-protein foods such as turkey, chicken, pork, beef, seafood and eggs.In addition, a diet high in essential fats will support an increase in the availability of protein in the brain for serotonin production.Vitamins and minerals, which are obtained from plenty of fresh fruits and vegetables, are needed to convert the tryptophan to serotonin.
25The B-Complex Vitamins The B-complex vitamins are essential to mental and emotional well-being.They cannot be stored in our bodies, so we depend entirely on our daily diet to supply them.B vitamins are destroyed by alcohol, refined sugars, nicotine, and caffeine so it is no surprise that many people may be deficient in these.
26Vitamin B1 (thiamine)The brain uses this vitamin to help convert glucose, or blood sugar, into fuel, and without it the brain rapidly runs out of energy.This can lead to fatigue, depression, irritability, anxiety, and even thoughts of suicide.Deficiencies can also cause memory problems, loss of appetite, insomnia, and gastrointestinal disorders.The consumption of refined carbohydrates, such as simple sugars, drains the body's B1 supply.
27Vitamin B3 (niacin) Pellagra produces psychosis and dementia Many commercial food products now contain niacin, and pellagra has virtually disappeared.However, subclinical deficiencies of vitamin B3 can produce agitation and anxiety, as well as mental and physical slowness.
28Vitamin B5 (pantothenic acid): Symptoms of deficiency are fatigue, chronic stress, and depression.Vitamin B5 is needed for hormone formation and the uptake of amino acids and the brain chemical acetylcholine, which combine to prevent certain types of depression.
29Vitamin B6 (pyridoxine): This vitamin aids in the processing of amino acids, which are the building blocks of all proteins and some hormones.It is needed in the manufacture of serotonin, melatonin and dopamine.Vitamin B6 deficiencies, although very rare, cause impaired immunity, skin lesions, and mental confusion.A marginal deficiency sometimes occurs in alcoholics, patients with kidney failure, and women using oral contraceptives..
30Vitamin B12:Because vitamin B12 is important to red blood cell formation, deficiency leads to an oxygen-transport problem known as pernicious anemia.This disorder can cause mood swings, paranoia, irritability, confusion, dementia, hallucinations, or mania, eventually followed by appetite loss, dizziness, weakness, shortage of breath, heart palpitations, diarrhea, and tingling sensations in the extremities.Deficiencies take a long time to develop, since the body stores a three- to five-year supply in the liver.Since intrinsic factor diminishes with age, older people are more prone to B12 deficiencies.
31Folic acidThis B vitamin is needed for DNA synthesis. It is also necessary for the production of SAM (S-adenosyl methionine).Poor dietary habits contribute to folic acid deficiencies, as do illness, alcoholism, and various drugs, including aspirin, birth control pills, barbiturates, and anticonvulsants.Folic acid deficiencies have been linked to depression in clinical studies. Folic acid deficiency causes serotonin levels in the brain to decrease.Psychiatric patients with depression have much higher rates of folic acid deficiency than the general publicAsparagusBananasBroccoliSpinachDried beansOranges Peanuts Peas
32Omega-3 fatty acids,Eat foods that are high in Omega-3 fatty acids, have been shown to raise serotonin levels in the brain, which may reduce the feelings of depression.These foods include nuts, grains, seeds, beans and deep-water fish such as salmon, mackerel, sardines and herring.This is a more natural alternative to antidepressants
33MagnesiumAccording to the most recent researches low magnesium plays a crucial role in the development of depression, attention deficit disorder, heart attack and diabetes.Magnesium is essential:for the formation of healthy bones and teethin the transmission of nerve impulsesmostly for the relaxation of musclesin activating several enzymesin the conversion of carbohydrates, fats and proteins into energy.Several hundred bodily functions require magnesium, as blood coagulation, insulin production, normal heartbeat, muscle and nerve functions.
34Magnesium The symptoms of magnesium deficiency include anxiety, depression,restlessness, confusion,irritability, brain fog,fatigueirregular heartbeat and tightaching muscles.cold hands and feet, muscle cramps in legs or feet
35MagnesiumTreat depression by adding foods that are high in magnesium to your diet, since magnesium deficiencies have also been recently linked to this condition.Foods that are high in magnesium include fish, barley, artichokes, buckwheat, oat bran, almonds, cashews, pine nuts, black beans, white beans, cornmeal, spinach, tomatoes, pumpkins seeds and soybeans.You can also take a magnesium supplement as well, either isolated or as part of a multi-vitamin formula.
36Seleniumis an antioxidant which assists vitamin E to protect cells from damage from free radicals.Selenium plays and important role in supporting the immune system and in a healthy cardiovascular system.Low levels of selenium have been linked to increased risks of cancer, inflammatory diseases and cataracts.It is also important as it is necessary in the production of thyroid hormone. Selenium also helps to protect against heavy metal damage.
37SeleniumOne symptom of hypothyroidism, or low thyroid function, is depression.For the synthesis, activation, and metabolism of thyroid hormones, selenium is required.Deficiencies in selenium could exacerbate the affect thyroid disease has on mood.Selenium deficiency has been linked to depression in adolescents who abuse alcohol.Alcohol depletes minerals, such as selenium. Some people, such as those who have had gastrointestinal bypass surgery or have Crohn's disease, absorb selenium less efficiently and are at risk.Meat and seafood are the best sources of selenium, and vegetarians may be at risk of low dietary intake and deficiency.
38SeleniumLack of can cause bad moods. Individuals suffering from a lack of selenium have been shown to be more anxious, irritable, hostile, and depressed than their non-lacking counterparts.Correcting deficiencies normalizes mood, but getting more does not elevate mood furtherBe sure to get your daily dose by eating a Brazil nut, or tuna sandwich, sunflower seeds, whole grain cereals, or swordfish.
39CHROMIUMThis mineral is vital for keeping blood sugar level stable because insulin, which clears glucose from the blood, can't work properly without it.Chromium helps maintain normal serum cholesterol levels and also helps to control the production of insulin.It increases immunity, regulates blood sugar, food cravings, and the body’s use of proteins, carbohydrates, and fats.It also helps in protein synthesis.Certain chromium compounds are being used to prevent memory loss and arrest deterioration due to Alzheimer’s disease.
40Chromium deficiency Symptoms Fatigue, Anxiety, Depression, Hyperactivity,Irritability, Bipolar disease, Mood swings,Learning disabilities,Glucose intolerance,Elevated blood cholesterol and triglyceridesCoronary blood vessel disease,Stunted growth, Infertility,Obesity, Neuropathy,In fact it turns out that just supplying proper levels of chromium to people with atypical depression can make a big difference.
41Chromium Food sources of Chromium include: Whole grains, Bread, Brown rice, Meat, Broccoli, Mushrooms, Green beans, Brewer’s yeast, Beef, Beer, Chicken breast, Chicken legs, Calves’ liver, Cereals, Cheese, Eggs, Fish, Sea food, Corn, Potatoes, Diary products, and Fresh vegetables. Herbs are also rich in chromium. Herb sources of chromium include:Wild yam, Nettle, Catnip, Oat straw, Licorice, Horsetail, Yarrow, Red clover and Sarsaparilla.
42About Chocolate???Some of dark chocolate’s benefits come from resveratrol, an antioxidant (immune system booster) found in red wine, among other products.Its mental health benefits include the ability to boost brain levels of endorphins (natural opiates) as well as serotonin (a mood-altering chemical on which many antidepressants act).Because it can increase serotonin levels in the brain, dark chocolate also may increase serotonin production in the gut, and thus help your immune system.
43The recommended dose is one ounce per day. it may help reduce blood pressure and increase arterial blood flow, reduce the chance of blood clots and lower LDL (bad) cholesterol.Eating too much chocolate each day can cause complications includingmigraines, weight gain,digestive tract problems (such as diarrhea),kidney stones and heartburnDark chocolate seems to have less of an impact on heartburn than milk chocolate and it may also be less of a problem in gallbladder disease, but no promises there.And all chocolate contains caffeine, which is a problem for some as well.
44What to avoid!!!Reduce the amount of stimulants in your diet, such as caffeine and high amounts of sugar.While these substances may provide a temporary mood lift and an increased amount of energy, they may also cause insomnia, disruptive sleep patterns, irritability and moodiness that can easily aggravate the symptoms of depression
45Food & Mood Rules ① Take it slow. ② Eat well and spread it out. ③ Cut back on sugar, caffeine, & saturated and trans fats; eat more ω-3 rich foods④ Lace a real-foods diet with super mood foods⑤ Exercise!!!⑥ Drink water.⑦ Supplement responsibly.
