Sourdough Bread and Sleep (Credit-Canva)
Sleeping is a fundamental human need, but still, a huge portion of the population struggles to get sufficient restful sleep. There are many reasons as to why that is the case, some people knowingly push their bodies to stay awake, while others may suffer with some illness making it difficult for them to sleep. According to the American Psychiatric Association, sleep disorders affect more than 50 million individuals in the United States alone. Those who routinely experience restless nights understand the frustration and impact of it on daily life. As such, the search for natural sleep remedies is a common pursuit. Surprisingly, a simple staple like sourdough bread may offer unexpected benefits for promoting better sleep quality.
The connection between your gut health and sleep quality has been recognized more and more by researchers. According to them, a healthy gut microbiome is a place where the complex community of microorganisms live inside the digestive tract and that plays a crucial role in overall well-being. While it does play a huge role here, you will see how it also plays important roles in other bodily functions such as sleep. This connection has also been called the gut-brain axis, which is the bidirectional communication or in simple language a 2-way communication between your gut and the central nervous system. A 2022 review published in Sleep Medicine Reviews helped us understand this relationship better and showed how disruptions in sleep patterns can negatively impact the gut microbiome, and conversely, imbalances in gut health can contribute to sleep disturbances. Basically, if your gut isn’t happy with your nutritional choices, your sleep is also not going to be restful or good. This research underscores the importance of maintaining a healthy gut for optimal sleep.
Several studies have researched the impact of gut health on sleep quality. A 2019 study published in PLoS One looked into whether diverse gut microbiomes could improve sleep quality for people. The researchers discovered that providing the gut with supportive nutrients had a good influence on sleep health. Sourdough bread stands out from other breads because of its nutrient profile and how it is made. While other breads need commercial yeast, sourdough is made with wild yeast starter, which has to undergo a fermentation process, social media has made this process well recognized as many people make sourdough starters and show the process of fermentation. This fermentation is key to sourdough's gut-friendly properties, as explained by WebMD. Healthcare professionals emphasized the importance of fermentation, explaining that it creates prebiotics, which serve as food for the beneficial bacteria in the gut. These prebiotics found in sourdough can support a healthy gut microbiome, which, as previously discussed, can positively impact sleep. Sourdough bread is also a low-glycemic-index food, as confirmed by a 2021 study in Foods. Low-glycemic foods are digested more slowly, minimizing the burden on the body's sugar processing and potentially improving sleep.
A 2019 study in the American Journal of Lifestyle Medicine found that college students, who on top of their already time and energy-consuming courses, consumed high amounts of added sugars often had poorer sleep quality. Similarly, a 2019 study in the American Journal of Clinical Nutrition found that postmenopausal women with high-glycemic index diets had a higher risk of insomnia. While a single slice of sourdough bread won't magically fix sleep problems, it can be a very important addition to a balanced diet. Combined this with other sleep-promoting foods and lifestyle habits and you will see how sourdough bread's gut-friendly and blood sugar-regulating properties may contribute to better sleep.

Choline is often known as "brain food". It is a nutrient related to B vitamins that play an important role in body and brain functions. However, the concerning part is about 90% of people do not consume enough of it.
It is essential for producing acetylcholine, which is a neurotransmitter that helps neurons or the nerve cells to build connections and communicate effectively. As people age, acetylcholine levels naturally decline. When these levels are lower than usual, it can cause conditions like Alzheimer's disease. Research also suggests that low levels of acetylcholine can impair memory, focus, and the ability to recall words.
As per a 2021 study published in the journal Behavioral Neurology, individuals who consumed between 188 to 400 mg of choline on a daily basis had a lower risk of cognitive decline. They had at least 40% less risk of experiencing cognitive decline compared to those with lower intakes of choline.
There are various forms of choline some benefit more than others.
For instance phosphatidylcholine is a type of choline that is found in eggs and is linked with lower dementia risk. A 2019 study observed that every additional 50 mg per day of phosphatidylcholine intake was associated with a 10 percent decrease in the likelihood of developing dementia. Since a large egg contains around 169 mg of choline, most of which is phosphatidylcholine, incorporating eggs into the diet can be particularly effective.
There are other emerging research in this field that suggests that increasing choline intake after Alzheimer's diagnosis could also slow the progression of the disease. It could also provide potential benefits even in the later stages of cognitive decline.
Other than helping the brain stay sharp, choline can also help maintain healthy liver function. It can play an important role for fat and glucose metabolism and reduce the risk of metabolic diseases like fatty liver disease and Type 2 diabetes.
It could also contribute to cardiovascular health by controlling inflammation, which is one of the leading reasons for heart diseases, including stroke.
Although the body makes a small amount of choline naturally, it is not sufficient to meet daily needs. The recommended Daily Value (DV) for choline is 550 mg. This amount typically needs to be obtained through diet or supplements.
While it’s possible to get enough choline through food, certain groups, such as older adults or those following a plant-based diet, may find it challenging. In such cases, supplements may be considered. However, not all multivitamins provide sufficient choline, so selecting a specific choline supplement — ideally around 300 mg — could be necessary. Consulting with a healthcare provider before starting supplements is always advisable.
There are many common food that contains choline, some of them include:

Often tossed aside without a second thought, banana peels make up nearly 35% of the ripe fruit’s total weight. Yet, they are not only edible but also brimming with nutrients that could offer significant health benefits. Incorporating banana peels into your diet is an easy way to boost your intake of vitamins and minerals while contributing to efforts against food waste.
Banana peels are rich in key nutrients such as potassium, dietary fiber, polyunsaturated fats, and essential amino acids. Among these, fiber plays a vital role in promoting digestive health, stabilizing blood sugar levels, and supporting heart health. Meanwhile, the potassium content can help manage blood pressure, protect bone density, and reduce the risk of kidney stone formation.
Research also highlights that banana peels are abundant in antioxidants, particularly when the fruit is unripe. Antioxidants are crucial for combating inflammation and may help protect against chronic diseases such as heart disease, cancer, and diabetes. Therefore, integrating banana peels into meals can add a powerful nutritional punch.
However, there are a few considerations to keep in mind. Conventional bananas are often treated with pesticides, and while peeling the fruit usually minimizes exposure, consuming the peel could lead to higher intake of pesticide residues. Pesticide exposure has been associated with health risks including autism, certain cancers, hypertension, diabetes, and cognitive decline. To minimize this risk, it is advisable to choose organic bananas whenever possible and to wash the peels thoroughly before use.
Another potential drawback is the taste and texture of banana peels, which some people find unappealing due to their bitterness and toughness. Opting for very ripe bananas and cooking the peels can help make them softer and sweeter, improving their palatability.
For those willing to experiment, banana peels can be prepared in various delicious ways. Start by selecting ripe bananas, washing the peels carefully, and removing the stem. The peels can then be blended into smoothies or added to banana bread batter. Cooking methods like baking, boiling, or frying not only soften the peels but also make them suitable for savory dishes. In fact, cooked banana peels have been used as substitutes for bacon or pulled pork in plant-based recipes. They can also enhance stir-fries, curries, and sandwiches, adding both flavor and nutritional value.
Incorporating banana peels into your diet is not just about maximizing nutrition—it’s also a step toward sustainable eating. They offer an innovative way to reduce food waste while supplying a range of important nutrients. Whether blended into a smoothie or cooked into a hearty dish, banana peels can add a nutritious and eco-friendly twist to your meals.
By making simple adjustments, like opting for organic bananas and experimenting with recipes, you can tap into the nutritional benefits of banana peels and make your diet more sustainable and health-conscious.
