导语：有些水果，吃了不仅能补充营养元素，还能让我们快乐起来，你知道吗？香蕉被称为快乐水果，顾名思义，是一种吃了就会快乐的水果。那么，你知道香蕉为什么被称为快乐水果吗？到底香蕉被叫快乐水果的原因是什么？原来，和它所含的一种物质有关，下面我们一起来了解。

含有5-羟色胺。专家表示，香蕉中富含碳水化合物，可以很快补充能量；香蕉中富含钾元素，有利于降低神经和肌肉的紧张度；此外，吃香蕉给人带来好心情还有个原因，因为香蕉中含生物胺类，生物胺类中有种物质叫5-羟色胺，5-羟色胺可以让人感到心情愉悦。

受到最广泛研究的神经递质是5-羟色胺，它是一种能产生愉悦情绪的信使，几乎影响到大脑活动的每一个方面：从调节情绪、精力、记忆力到塑造人生观。抗抑郁药如盐酸氟西汀就是通过提高脑内5-羟色胺水平而起作用的（但是科学家们已认识到事情远没有这么简单，问题有时不仅仅出在神经递质缺乏上。新的研究着眼于神经细胞的接收装置─树突上的受体，考虑它们的数量及敏感程度是否足以正常结合并处理神经递质。如果受体没有足够的活性，信息将无法传递下去，那么不论大脑中有多少游离的神经递质都是徒劳的。受体缺陷能导致诸多的麻烦）。5-羟色胺水平较低的人群更容易发生抑郁、冲动行为、酗酒、自杀、攻击及暴力行为。科学家们甚至通过改变实验动物脑内5-羟色胺的水平使他们更具有攻击性。

有趣的是，女性大脑合成5-羟色胺的速率仅是男性的一半，这点可能有助于解释为何妇女更容易患抑郁症。随着年龄的增长，5-羟色胺作用通路的工作效率会出现下降，因为活化5-羟色胺的受体减少了。据一项研究显示，60岁与30岁的人相比，大脑中5-羟色胺特异受体的数目已减少了60%。由于5-羟色胺的效力下降，随年龄增长患抑郁症的可能性增加。

对伴抑郁的酒精使用障碍患者，SSRIs能改善焦虑和抑郁，直接减少酒精吸收达15%—20%，但某些患者服SSRIs反而增加饮酒行为。对不伴抑郁的酒精使用障碍患者，SSRIs的研究结果混乱。当SSRIs治疗酒精依赖患者时，能加重SSRIs的胃肠不良反应。减少患者对酒的渴求程度，减少饮酒量。

另外，5-羟色胺还能增强记忆力，并能保护神经元免受“兴奋神经毒素”的损害。因此充足的5-羟色胺确实能在老化过程中防止脑损害发生。

除此之外，曾在医学物理实验中，血清素在旁效应中体现了一定的致死细胞的作用。

1、海鲜：像金枪鱼，蛤蜊，牡蛎，螃蟹，鲭鱼，三文鱼，鲱鱼，沙丁鱼和鱼油补充剂等脂肪鱼是五羟色胺的良好来源。

2、肉类：除蛋白质外，肉类如牛肉，猪肉，肝脏，土耳其和鸡肉含有5-羟色胺，可以帮助摆脱血清素缺乏。Bacons也是5-羟色胺的重要来源。

3、鸡蛋：蛋白是另一个非常重要的血清素来源。鸡蛋还含有许多其他维生素和身体所需的重要营养素。

4、乳制品：牛奶，酪乳，豆腐，奶酪等乳制品是五羟色胺食品的良好来源。印度奶酪，芝士也含有5-羟色胺。

5、蔬菜：蔬菜如大蒜，胡萝卜，南瓜，黄秋葵，芦笋，西兰花，菠菜，青豆，土豆，卷心菜，甜菜，生菜，洋葱和西红柿帮助创造5-羟色胺。这些都很容易在市场上获得，并有助于提高5-羟色胺的水平，因此属于富含5-羟色胺的食物。

6、坚果：杏仁，花生，腰果，开心果，松子，花生酱，榛子和核桃帮助制造5-羟色胺。这些坚果还含有大量的ω-3脂肪酸，有助于维持健康的皮肤，头发和指甲。

7、谷物：麸皮中含有5-羟色胺，可导致体内适当的细胞功能。它也富含纤维。麸皮的好例子是米糠，烤麦芽面包，麦片，土豆和大米。

8、种子：种子是非常丰富的5-羟色胺的来源。它们还含有蛋白质，钾，锌，铁，B族维生素，维生素E，镁和钙。南瓜种子，南瓜种子，西瓜种子，芝麻种子，亚麻种子，向日葵种子是含有血清素的一些种子。

Introduction: Some fruits can not only supplement nutrients but also make us happy after eating, do you know? Bananas are called happy fruits, as the name suggests, they are a type of fruit that will make you happy after eating. So, do you know why bananas are called happy fruits? What is the reason why bananas are called happy fruits? Originally, it is related to one of the substances it contains. Let’s learn more together.

Contains 5-hydroxytryptamine. Experts say that bananas are rich in carbohydrates and can quickly replenish energy; Bananas are rich in potassium, which is beneficial for reducing nerve and muscle tension; In addition, there is another reason why eating bananas can bring people a good mood, because bananas contain biogenic amines, among which there is a substance called 5-hydroxytryptamine, which can make people feel happy.

The most widely studied neurotransmitter is serotonin, which is a messenger that can generate joyful emotions and affects almost every aspect of brain activity: from regulating emotions, energy, memory, to shaping a worldview. Antidepressants such as fluoxetine hydrochloride work by increasing the level of serotonin in the brain But scientists have realized that things are far from simple, and sometimes the problem lies not just in the lack of neurotransmitters. New research focuses on the receptors on dendrites, the receiving devices of nerve cells, and considers whether their quantity and sensitivity are sufficient to properly bind and process neurotransmitters. If the receptors are not active enough, information cannot be transmitted, and no matter how many free neurotransmitters are present in the brain, it is futile of Receptor defects can cause many troubles. People with lower levels of serotonin are more likely to experience depression, impulsive behavior, alcoholism, suicide, aggression, and violent behavior. Scientists even made experimental animals more aggressive by altering their levels of serotonin in the brain.

Interestingly, the rate at which women’s brains synthesize serotonin is only half that of men, which may help explain why women are more prone to depression. As age increases, the efficiency of the serotonin pathway decreases, as the number of receptors that activate serotonin decreases. According to a study, the number of serotonin specific receptors in the brain has decreased by 60% compared to people aged 60 and 30. Due to the decreased efficacy of serotonin, the likelihood of developing depression increases with age.

For patients with alcohol use disorders accompanied by depression, SSRIs can improve anxiety and depression, directly reducing alcohol absorption by 15-20%. However, in some patients, taking SSRIs can actually increase drinking behavior. The results of SSRIs research on alcohol use disorders without depression are mixed. When SSRIs are used to treat alcohol dependent patients, they can exacerbate the gastrointestinal adverse reactions of SSRIs. Reduce patients’ thirst for alcohol and reduce their alcohol consumption.

In addition, serotonin can enhance memory and protect neurons from damage caused by “excitatory neurotoxins”. Therefore, sufficient serotonin can indeed prevent brain damage during aging.

In addition, in medical physics experiments, serotonin has demonstrated a certain lethal cell effect in the bystander effect.

1. Seafood: Fatty fish such as tuna, clams, oysters, crabs, mackerel, salmon, herring, sardine and fish oil supplements are good sources of serotonin.
2. Meat: In addition to protein, meat such as beef, pork, liver, Türkiye and chicken contain 5-hydroxytryptamine, which can help get rid of serotonin deficiency. Bacons are also an important source of serotonin.
3. Eggs: Protein is another very important source of serotonin. Eggs also contain many other vitamins and important nutrients that the body needs.
4. Dairy products: Milk, buttermilk, tofu, cheese and other dairy products are good sources of serotonin foods. Indian cheese, which also contains serotonin.
5. Vegetables: Vegetables such as garlic, carrots, pumpkins, okra, asparagus, broccoli, spinach, green beans, potatoes, cabbage, beets, lettuce, onions, and tomatoes help create serotonin. These are easily available in the market and help to increase levels of serotonin, therefore they belong to the category of foods rich in serotonin.
6. Nuts: Almonds, peanuts, cashews, pistachios, pine nuts, peanut butter, hazelnuts, and walnuts help manufacture serotonin. These nuts also contain a large amount of ω- 3 fatty acids help maintain healthy skin, hair, and nails.
7. Cereals: Bran contains serotonin, which can lead to appropriate cellular function in the body. It is also rich in fiber. Good examples of bran are rice bran, baked malt bread, oatmeal, potatoes, and rice.
8. Seeds: Seeds are a very rich source of serotonin. They also contain protein, potassium, zinc, iron, B vitamins, vitamin E, magnesium, and calcium. Pumpkin seeds, pumpkin seeds, watermelon seeds, sesame seeds, flax seeds, and sunflower seeds are some seeds that contain serotonin.
