Zelf neurotransmitters (o.a. dopamine, serotonine) beïnvloeden?

Goedendag,

Ik vraag me af welke mogelijkheden er zijn om neurotransmitters zoals dopamine, endorfine en serotonine etc. te verhogen.

Ik doel dan vooral op eenvoudige en praktische methodes zoals hardlopen of het eten van (pure) chocolade, dus zonder drugs of medicijnen.

Het lijkt me namelijk wel handig om een overzicht te hebben van activiteiten en voedingsmiddelen die een (bewezen) positief effect hebben op je hersenen en gemoedstoestand.

Alvast bedankt!

Boost your alertness with protein. Protein foods are broken down into their amino acid building blocks during digestion. One amino acid, called tyrosine, will increase the production of dopamine, nor epinephrine and epinephrine. These neurotransmitters are known for their ability to increase levels of alertness and energy. No one eats pure tyrosine, but eating foods high in protein will give you a slight mental boost. High protein foods include fish, poultry, meat, and eggs. If you can't eat those, try high protein foods that also contain significant amount of carbohydrates, such as legumes, cheese, milk, or tofu.

For relaxation and anti-stress, eat carbohydrates. Eating carbohydrates will trigger the release of insulin into the blood stream. Insulin goes about clearing all the amino acids out of the blood, with the exception of tryptophan. Tryptophan is an amino acid that normally gets crowded out by other amino acids in its attempt to cross the blood brain barrier, but when its competitors are out of the way, it enters the brain. Once in the brain, the tryptophan is converted to serotonin. Serotonin is a neurotransmitter that has the effect of reducing pain, decreasing appetite, and producing a sense of calm, and in too large a quantity, inducing sleep. Research has shown that dieters tend to become depressed about two weeks into a diet, about the time their serotonin levels have dropped due to decreased carbohydrate intake.

For the most beneficial effect of either carbohydrate or protein, eat them separately. For example, the energy boosting effect of protein will be offset if you start out a lunch of fish (pure protein) with a roll (mostly carbohydrate). Make the protein the first food that you eat, and then, go lightly on the carbohydrate if it is mental alertness you are after.

Caffeine can be an effective anti-depressant
Despite its bad rap, caffeine can do some good. For mild cases of depression which do not need medical attention, a little caffeine can be an effective anti-depressant. It has the added benefit of not needing to increase the dosage daily to get the same effect. Long-term epidemiological evidence more than supports the safety of a cup or two of coffee a day. More than that, however, can begin to have counterproductive effects in some people.

Likewise, folic acid is an important counter to depression. 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 public. As little as 200 micrograms was enough to relieve the depression -- that amount is easily obtained in a cup of cooked spinach or a glass of orange juice.

Lack of selenium 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 further. It is speculated that selenium may have some unknown neural function, but as of yet, its mode of action is unknown. Be sure to get your daily dose by eating a Brazil nut, or tuna sandwich, sunflower seeds, whole grain cereals, or swordfish.

Put eggs back in your diet to improve memory and concentration. One nutrient that many of us are apt to be low on, in our fervor to avoid high-cholesterol foods, is choline. Choline is a B complex vitamin that is concentrated in high cholesterol foods like eggs and liver. A lack of choline can cause impairment of memory and concentration. Choline is a precursor to the brain neurotransmitter, acetylcholine. Acetylcholine is linked to memory. People given drugs that block acetylcholine flunk memory tests. Low levels of acetylcholine have been linked to Alzheimer's disease and poor memory. What a good excuse to put eggs back on your diet plan!

Bedankt!

Mijn insteek was inderdaad vooral het aanpassen van voeding, lichaamsbeweging en andere methodes (boos worden om het adrenaline te verhogen )

Neemt niet weg dat supplementen ook interessant zijn om eens naar te kijken.

google geeft 99% bullshit als je op zulk soort dingen wil zoeken dus is het kunst om resultaten op juistheid te controleren, iedereen kan wel vanalles zeggen natuurlijk wat nog niet de waarheid betekent

Ja zeg, of het hier wel allemaal klopt? Ik zie namelijk bijna nooit een bron vermeldt staan bij dingen die een ander van het net heeft gehaald.

Mijn opmerking zaait meteen paniek over het forum, dat is wat het probleem is.... Toch?
