Importance of foods in gut health of Adolescents – Fermented Food for Gut Health

The current generation of teenagers is burden with the different changes which includes changes of puberty & alterations of hormones, academic pressures, peer pressure, sleepless nights etc. The issue which is frequently ignored in this early stage of development is the health of our gut. An emerging situation attributes the balance of the gut microbiome not only to digestion, but also the mood, immunity, skin clarity, energy levels and mental state as well.

With regards to strategies that are quite natural and effective in helping adolescents to develop gut health, one factor that it is important to consider is that of eating fermented foods. Heavily laden with probiotics, enzymes, bioactive additional chemistry, fermented products can be used to repay the gut microbiome with commensal bacteria which form the core of transition and disposal health. The subsequent text will outline the most beneficial fermented products that can be introduced to teenage diet, explain their specific mechanics of action, and offer realistic, non-resistance-stimulating ways of adding them to the standard diet.

Gut health is very much important during the Adolescent period — Why?

The gut microbiome, ecosystem of trillions of bacteria inhabiting the digestive tract, has a decisive effect on a number of physiological processes which have a specific significance during adolescence: 

• Digestion and absorption of nutrients: the microbial communities facilitate digestion and absorption of nutrients following decomposition of nutrients in the diet. 
• Mood control: more than 90 % of serotonin which is a neurotransmitter is produced by microorganisms. 
• Skin health: Such imbalance can result in acne, eczema and inflammation of the skin.
• Weight and metabolism: the metabolism routes that control the calorie-burning and energy-storing are adjusted with the help of gut-related microorganisms.

Adolescents demonstrate the increased vulnerability to intestinal dysmsgie, which is partially explained by the disorders of eating schedule and, in particular, 

• The lack of breakfast 
• Overindulgence in the food industry products and sugar 
• Constant use of antibiotics during the acne therapy may disrupt the bowel
• The same can be done by poor sleep and late meals.
• Cosmetic chemical exposures. 

Dysbiosis microbial activity have been linked with the appearance of such symptoms as bloating, constant fatigue, mood swings, higher risk of getting infections as well as skin diseases. In this case, consumption of fermented foods has been revealed to have restorative impacts with regard to the microbial communities in the gastrointestinal tract.

Fermented foods are a part of foods which have been subjected to basic metabolic changes through the bacteria and yeast by the lactobacillus type of fermentation usually referred to as lacto-fermentation. he transformation confers nutritional and physiological advantages, such as:

• Adding probiotics to the diet
• Eating of sufficient foods which helps for digestion 
• Vitamin-B complex intake 
• Short fatty acids synthesis

An overview of the most pertinent fermented foods that are at the same time teen-friendly and enhance the health of the intestine is next:

1. Yogurt (Curd)

Yogurt or curd forms yet another traditional probiotic pillar which has been augmented with lactobacillus and Bifidobacterium stain that helps build intestinal homeostasis by boosting immune efficiency.

Infants and children have to have healthy gut so that they have healthy skin.

• It counteracts the risk of gastrointestinal disturbances caused by the usage of antibiotic agents 
• Promotes lactose digestion 
• Healthy gut are helpful for deposition of Calcium and protein
• Maintain the structure of the skeleton and also have anti-inflammatory effects that reduce the rate of acnes. 

Some Tips:

• Unsweetened, plain preparations should be preferable to the flavored preparations 
• The flavor may be improved by increasing it with fruit, nuts, or small quantity of of honey.
• It is recommended to take into account yogurt as an examination in terms of breakfast or after school snacks.

2. Kimchi

Kimchi is a conventional Korean food item made by lacto-fermentation of cabbage, radish and other vegetables along with garlic, chili pepper and incorporation of various spices. 

Kimchi, typically is eaten because of its crispy texture and good probiotic quality and is described to have a pungent smell and spicy flavor.

Nutritional standpoint, kimchi: 

• It also has many lactic acid bacteria and this increases the diversity within the gut microbiota.
• It contains a lot of phenolic antioxidants and soluble dietary fibers.
• May have beneficial qualities, that include a clearer head and decreased inflammation on a systemic basis. 

The common ways to implement kimchi into the diet of adolescents are 

• Put it in rice bowls, wraps, sandwiches, noodle bowls or swirl it in hot rice meals, fried rice or scrambled eggs
• Asian food palate to the diet; and letting those who like spicy foods enjoy it.

3. Miso

Other foods include the soybean paste called miso which is important in the Japanese foods.

It is prepared from a type of soybeans which left to ferment with salt & koji that is a type of special mold. 

Benefits for Adolescents: 

• Probiotics, protein & minerals 
• It enhances the flavor. 
• It contains iso-flavones that is able to regulate endocrine pathways in the body

Putting miso in soups especially miso soup is very effective.

• Do not heat it in any other way such as by boiling which destroys the live cultures. 
• Miso may be consumed with bread  
• Toss in sesame oil with garlic can be served as dipping sauce and also it is really delicious.

4. Pickled of different Vegetables which is a Natural Fermentation

Pickled vegetables by natural fermentation form another food category which differs with the vinegar-based pickles when it comes to the process of spoilage: 

• Pickles are fermented in salt and water solution to such an extent that probiotic bacteria develops over a long duration of time.
• Intake of these preparations presents a number of clinical benefits to teenagers such as betterization of digestive physiology, induction of satiety and the supply of dietary fibre. 
• The use of commercial foodstuff not under the category is however, vital to be avoided because of their overdependence with vinegar and use of other preservatives. 
• As substitutes to this industry product, retailers and home cooks will be encouraged to focus on fermented products containing what is labelled as live cultures, or to make their own salt-brine pickles.

5. Sourdough Bread

Sourdough is prepared through the fermentation of flour mixed with water in the presence of the indigenous yeast and bacteria, which makes the product more digestible than the ordinary bread. 

• Epidemiology studies have shown that this type of fermentation is beneficial to teenager and young adults as compared to young adults because it is less gluten laced.
• The natural fermentation as used in the production of sourdough comparing to industrially kneaded bread increases bioavailability of micronutrients. 
• Moreover, cleaner label product can be offered by virtue of the fact that no additives and preservatives typical of sourdough production are used. In terms of the suggested applications, sourdough can replace the sandwich bread or be used as a topping on a piece of toast. 
• It also is a healthy energy source when taken together with the nutrient dense spreads — like avocado, hummus or nut butter — to help in the energy demands of the adolescents. 
• Whole-grain sourdough bread is available to people who want to add more dietary fiber to their system.

6. Kombucha

It is like a fermented tea product which is filled with few good acids, enzymes & probiotics. Its fizzy nature makes it to be a delight to the teenagers, who usually find its flavour matching with the taste of carbonated drinks. 

• The facts show that kombucha can help to rationalize gastro-intestinal issues, including bloating and enzyme digesting, and deliver a nutritionally enhanced substitution to high- sugar carbonated liquids. 
• Also, the action of certain polyphenolic components can suppress the harmful effect of oxidative stress that, in turn, could promote mood and homeostasis in energy levels. 
• It is still not possible to come up with concrete findings about its safety and/or efficacy, since clinical trials are little, and the current literature has been unable to show any conclusive results. 
• An adequate consumption is advised to be between 100 and 150 ml of intake per day, but not exceeding high sugar content, organically manufactured products. 
• Evening dosage should be done with caution as a lot of commercial preparations contain caffeine.

7. Fermented Cheese

Some cheeses, especially cheddar, gouda, mozzarella and parmesan are aged as well as undergoing the process of natural fermentation, which generates useful bacteria although not to the levels that are present in yogurt. 

Such type of microorganisms are having actic acid bacteria & bifido-bacteria. 

• More of this kind of cheese has protein and calcium.
• An average 28 grams serving provides about 12 % Daily Value calcium, 10 % protein and 10 % vitamin B12. 
• On the impact on gut microbiota, eating these cheeses was found to increase the variety of intestinal bacteria and the number of representatives of the family Lachnospiraceae when eaten in reasonable quantities. 
• The food products are also easily incorporated into the diets usually followed by teenagers and can be fitted in packed lunch, sandwiches and snacks during and after exercise. 
• Those that are raw or simply called artisanal cheeses with labeling of either aged or cultured are the best to give maximum benefits. 
• On the contrary, cheese slices and spreads should be avoided which are highly processed.

8. Different Fermented foods like idli, dosa which is an Indian food

Other preparations made by the Indians like idli, dosa, appam, and dhokla are obtained after fermenting rice and lentils overnight so besides increasing the digestibility, it also increases the nutritional value. 

• Fermented and this slow absorption of the carbohydrates is easier on the gastrointestinal tract
• The end product is a balanced combination of macronutrients where the complex carbohydrates are combined with the vegetal protein.
• The fact that these foods are usually soft and light textured means that they can be used by the picky eaters. 

With it one can eat sambar or coconut chutney. Another way is to give dosa batter an extra strength by adding grated vegetables, which further helps in adoring extra fiber. Fermented foods can also be provided to the adolescents with the help of progressive acclimatization and habituation.

Initiation of Fermented Foods to the adolescent people:

It is usually necessary to develop a step-by-step process to make fermented foods appealing to the teenage audience. 

Recommendations include: 

1. Yogurt can be started which actually adolescent people start to eat 
2. When it comes to fermented foodstuffs, teens can make ferment pickles or sourdoughs, etc.
3. Fermented foods are sneaking up in the food: add sauerkraut to your burger, miso to all the soups or yogurt to any smoothie.
4. Develop a non-intimidating attitude when preparing meals; present a lot of choice and give way to self-will.

Cautions 

Despite the fact that all fermented foods are normally discussed as having a low risk, there are some precautions that have to be considered. 

• To begin with, pickled foods contain a lot of salt to the extent that it should be taken with caution, especially in the case of adolescent hypertension. 
• Second, histamine sensitivity is not very common during the adolescent phase though there can be a few individuals who will show an adverse reaction towards aged or fermented products. 
• Third, kombucha, yogurt and flavored kefir have to be tightly controlled ensuring that 200 calories are not consumed in too large amounts. 
• Fourth, in case of susceptible teens, allergies, especially in respect to dairy and soy may crop up as a consequence of eating yogurt or miso. 
• Lastly, young people with prolonged stomach/immune system diseases need to visit a medical expert before using fermented goods.

Gut-brain axis refers to a relationship between the gut and the brain, which is considered as a bi-directional interaction between gastrointestinal activities which have a regulatory pattern of psychological conditions, as well as, psychological processes, which have an impact on the gastrointestinal activities. 

• Fermented foods with probiotics may be able to relieve the symptoms of anxiety and depression
• It also helps to increase the levels of emotional resilience, enhance the cognitive ability of adolescents
• It helps to maintain the emotional stability of adolescent groups.

The microbiological homeostasis is necessary to the development of adolescents both in physical, cognitive and affective respects. These foods are not so expensive, also it is highly accessible and pleasant form of developing balance. Inclusion of small amounts of- yogurt, pickles and dosas in everyday diet may have long term sweeping results. 

As the adolescents will continue receiving parental guidance, they will have the chance to develop long-lasting pro-biotic instructions putting the primary emphasis on gastrointestinal microbiota, thus securing the future well-being.
