Yogurt is one of the most popular fermented dairy products worldwide, and it has numerous health benefits other than its basic nutrition. In general, yogurt is considered a nutrition-dense food due to its nutrient profile and is a rich source of calcium, magnesium, and many more nutrients. In addition, it provides proteins with a higher biological value and almost all the essential nutrients needed to maintain good health.

Moreover, yogurt has other health benefits, including its ability to strengthen your immune system by increasing cytokine and antibody production.

Benefits of Eating Yogurt Before Bed

Rich In Essential Nutrients

Yogurt is known to have so many vital nutrients as it is an excellent source of high-quality proteins, digestible carbohydrates, calcium, magnesium, phosphorus, and vitamin B12. Moreover, it is quite fascinating to have all of those nutrients in one small cup of yogurt. The typical serving size for yogurt is equivalent to 170–175 g, although serving sizes may vary from country to country.

According to one study, an average 170 g portion of popular low-fat fruit-flavored yogurt gives our bodies about 6% potassium and magnesium, 20–24% calcium, 26% phosphorus, and 30% of vitamin B12. Furthermore, it is highlighted in the same study that many national health agencies promote yogurt as a viable option to get the essential nutrients in one daily serving.

Furthermore, Health Canada includes yogurt in its dairy and alternative food groups in the Canadian Food Guide. Also, the USDA recommends the consumption of yogurt to help Americans achieve the recommended intake of essential nutrients. Thus, it is ideal to consume yogurt a while before bedtime to maximize your nutrient intake at the end of your day.

Our immune system is an important contributor to diseases and illnesses, it helps us combat illnesses and improve our physical well-being. There have been several studies conducted that indicate that yogurt consumption can enhance and strengthen our immune system.

In one study, 33 male and female students between the ages of 22 and 29, consumed 100 g then 200 g of yogurt for four weeks. The research aimed to see the effects of eating yogurt on the students’ immune systems. Moreover, the study found that there was an increase in the stimulated production of proinflammatory cytokine which is responsible for combating illnesses and infections.

Additionally, the study observed a higher resistance against some common infectious diseases due to the participants consuming yogurt daily. Therefore, individuals who consume yogurt daily can have a much stronger immune system and more active infection-fighting cells. Thus, you should eat yogurt before bedtime if you feel tired or sick to feel better the next day.

It Can Reduce Stress Levels

One of the most intriguing facts about yogurt consumption is that it has the ability to reduce your stress levels. This is because of the presence of probiotics in yogurt, which can help in relieving stress by reducing activity in the insula. Moreover, the insula is a part of our brains that contributes to the perception of sensations associated with danger or threat.

One study was conducted with a placebo-controlled, randomized clinical trial to measure the levels of two stress-induced hormones, adrenocorticotrophic hormone (ACTH) and cortisol. Moreover, the participants were divided into two groups (109 placebo subjects and 115 test subjects) and were given 100 g of yogurt daily for 12 weeks. The yogurt contained two probiotics, Lactobacillus Gasseri, and Bifidobacterium Longum to efficiently observe the effects of the yogurt on stress levels.

It was concluded that the participants’ serum ACTH levels were significantly decreased by yogurt consumption and a reduction of cortisol in saliva was seen in the test subjects. Furthermore, the results suggest that yogurt consumption has the ability to improve your health by alleviating stress, making it ideal to consume before bedtime.

Weight Control

Yogurt can be a great addition to your diet, although some people often cut down on the consumption of milk and dairy products to lose weight. However, there is little evidence to support the idea that the consumption of dairy products such as yogurt can lead to excess weight gain. On the contrary, there is numerous evidence that suggests cutting down on yogurt in your diet can be counterproductive.

In one study, 34 healthy but obese women participated in the research, with one group receiving 1100 mg of calcium/day in the form of 3 servings of fat-free yogurt and another group receiving 500 mg of calcium/day. Furthermore, at the end of the study the yogurt group lost about 22% weight (average loss of 13 pounds), 61% body fat, and 81% truncal fat that the other group who did not consume yogurt.

Furthermore, the results indicate that the calcium in the yogurt helps in weight and fat loss, as well as calorie restriction. Moreover, it indicates that yogurt consumption has a greater effect compared to an equivalent amount of supplemental calcium. Thus, you can add yogurt to your diet as it may make an important contribution to your ability to control your body weight.
