Five best snacks with mood lifting power


Change your diet, change your mood? Science says the answer is yes. Food isn't just fuel for the body; it feeds the mind and changes our moods. Food scientists are still exploring the big picture regarding food and mood, but it's clear that certain foods have a feel-good factor.


Bananas offer serious mood-lifting power, with their combination of vitamins B6, A, and C; fiber; tryptophan; potassium; phosphorous; iron; protein; and healthy carbohydrates. When you eat a banana, you’ll get a quick boost from the fructose as well as sustaining energy from the fiber, which helps prevent a blood sugar spike and ensuing drop in energy and mood. Carbohydrates aid in the absorption of tryptophan in the brain, and vitamin B6 helps convert the tryptophan into mood-lifting serotonin. Bananas are also a great source of potassium and also offer iron, which is crucial to producing energy and fighting fatigue.

Walnuts contain a handful of components that contribute to a good mood, including omega-3s, vitamin B6, tryptophan, protein, and folate. Higher blood levels of omega-3s have been linked with better mood and lower rates of depression, while lower blood levels of omega-3s have been associated with higher rates of depression and negative feelings. The standard dosage of omega-3 oils recommended by many experts is one grammes (1,000 mg) per day. You’ll get about the same amount, as well as a healthy dose of fiber and protein, in just half an ounce of walnuts. About two teaspoons of walnut oil will also do the trick, but you won’t get the all the nutrition you would from the whole nut.
Sunflower seeds are a super source of folate and magnesium, two substances that play a significant role in regulating and boosting mood. Just a handful of sunflower seeds delivers half the daily recommended amount of magnesium. Magnesium, in addition to regulating mood, plays an essential role in hundreds of bodily functions. Magnesium deficiency is often responsible for feelings of fatigue, nervousness, and anxiety (since it triggers an increase in adrenaline), and it’s been linked to various mood disorders. Sufficient, stable magnesium levels, on the other hand, help us achieve a calm and relaxed state, the perfect precursor to a good mood.

It’s so effective, in fact, that scientific studies have shown magnesium supplementation to be beneficial in treating major depression, suicidal tendencies, anxiety, irritability, and insomnia. Folate (also known as vitamin B9 and as folic acid) is a B-complex vitamin that’s intimately linked with nervous system function. Folate deficiency may result in feelings of irritability, depression, and brain fog, as well as insomnia. Being well rested and keeping a clear head are two of the primary factors in fuelling a good mood, so snacking on sunflower seeds is a smart move in more ways than one. Sunflower seeds are a good source of tryptophan and are often recommended by nutritional experts as a natural method of boosting serotonin levels. They’re also rich in fiber, which helps maintain stable hormone levels—one of the keys to keeping even-keeled.

Dark Chocolate: Chocolate contains a number of substances that elevate mood, including fat, sugar, caffeine, phenylethylamine, flavonols, theobromine, and tryptophan. Caffeine and theobromine are two naturally occurring stimulants found in chocolate. Along with sugar and fat, these substances provide a swift burst of energy and mood-lifting power. Chocolate also contains the mood-boosting compounds phenylethylamine, tyramine, tryptophan, and magnesium. While these substances are found in many other foods, even in higher concentrations, chocolate has an advantage because of its appeal on several sensory levels: it has a rich, mouth-pleasing texture; an intense taste; and an appealing aroma. For many of us, just the idea of indulging in chocolate is enough to elicit a positive emotional response.

In addition to these natural pick-me-ups, when you eat chocolate, a number of reactions occur, including the release of serotonin in the brain and mood-elevating endorphins in the body. This heady combination can result in a temporarily lifted mood and even a fleeting feeling of euphoria, which may explain why some people turn to chocolate when they’re feeling blue.Read More ...
