Summer heat is a serious physiological challenge for the human body. In an attempt to cool down, we often intuitively reach for ice-cold sweet carbonated drinks, fruit juices, cold coffee with syrups, or industrial lemonades. However, modern molecular biology and gastroenterology are sounding the alarm: what brings instant refreshment to the oral cavity can be a real disaster for our gastrointestinal tract.

Our gut is a giant symbiotic ecosystem inhabited by trillions of microorganisms. Changes in our diet and our eating behavior are determinants of health, since first and foremost we provide nutrition to our own microbes. Bacteria form immunity, control inflammation, synthesize vitamins and neurotransmitters. In this scientific article, we will take a detailed look at why popular summer drinks destroy our microbiome, which 7 alternative drinks can restore the ecological balance of the gut, and why true health is impossible without in-depth research into the microbiome and the use of the Biocode4U algorithmic nutrition plan .

1. The physiology of summer thirst: why sugary drinks kill the microbiome

In the heat, blood flow is redistributed to the skin to ensure sweating, which causes the digestive organs to experience a state of temporary ischemia (lack of oxygen). At this point, intestinal motility and enzyme production slow down significantly. If, during this vulnerable state, the intestines are hit with a shock dose of refined sugar or artificial sweeteners from soft drinks, the consequences become critical.

Scientists prove that artificial sweeteners (such as aspartame), which are massively added to "diet" summer drinks, rapidly increase blood sugar levels and directly stimulate the growth of undesirable species of enterobacteria in the intestinal microbiome. Excess simple carbohydrates become ideal fuel for opportunistic microorganisms and yeast fungi (for example, Candida ). Violent fermentation occurs, the release of toxic gases, which leads to acute flatulence (bloating) and damage to the protective mucosal barrier. The absence of beneficial bacteria and such a chemical shock contribute to chronic inflammation and increase intestinal permeability.

2. Top 7 soft drinks that heal the intestines

To be microbiome-friendly, a beverage should contain prebiotics (food fibers for bacteria), polyphenols (plant antioxidants that regulate the growth of flora), and be free of refined sugar. Studies show that the interaction between polyphenols and microorganisms modulates metabolism and provides significant health benefits. Here are 7 science-backed options for summer refreshment:

1. Water with berry extracts (blueberries, huckleberries, blackberries) Instead of sweet compotes, it is better to use clean water with macerated berries. Berries are rich in phenolic compounds and anthocyanins. Extracts of edible plants and berries act as powerful growth stimulants for beneficial microorganisms. They have a selective antimicrobial effect: they suppress pathogens, but nourish lacto- and bifidobacteria.

2. Cold tea with nettle or mint Herbal cold infusions are a classic of phytotherapy. According to in vivo studies, extracts of nettle, dill and plants of the genus Sideritis are able to specifically modulate the intestinal microbiota and the production of local cytokines, relieving inflammation of the mucous membrane. Such a drink perfectly tones and supports the immune balance of the intestine.

3. Iced Matcha This trendy drink for millennials and IT professionals has profound functional potential. Matcha green tea contains a huge amount of catechins (polyphenols). In addition, the right microbiological matcha can physiologically reduce cortisol (stress hormone) levels and eliminate anxiety through the gut-brain axis.

4. Fermented dairy drinks (Ayran or Kefir) Fermented products (yogurt, kefir) contain pre-, pro- and postbiotics, in particular lactobacilli, which reduce the number of unwanted microorganisms in the intestines. However, they should be consumed with caution: if your enterotype (for example, with a Ruminococcus dominance ) is prone to fermentation of dairy products, it is better to replace cow's milk with lactose-free or alternative milk.

5. Vegetable smoothies with pumpkin or carrots Fruit juices contain too much fructose. Instead, vegetable smoothies are ideal. Pumpkin and carrot fruits are powerful natural prebiotics. Vegetables contain a large amount of dietary fiber (pectin, lignin, cellulose), which serve as natural enterosorbents, remove toxins and are a substrate for anaerobic bacteria that form short-chain fatty acids (SCFA) to nourish the epithelium.

6. Apple Pectin Drink Adding apple pectin concentrate to water or drinks has a pronounced therapeutic effect. Highly methoxylated pectin improves insulin resistance, reduces cardiometabolic risks, and stimulates gastrointestinal motility.

7. Functional whey with probiotics An innovative solution is to create whey-based drinks with the addition of specific clinically proven strains of microorganisms that are aimed at strengthening bones, improving mood or losing weight. These are the drinks of the future that act as medicine.

3. Why there is no universal advice: the importance of microbiome research

Despite the benefits of the listed drinks, modern 4P medicine (personalized, predictive, preventive, patient-centered) emphasizes: what is ideal for one person may cause exacerbation in another. Each person has a unique microbial profile. For example, if you lack mucin-degrading bacteria or putrefactive flora prevails, even the most useful vegetable fiber from pumpkin will cause you severe bloating.

That is why the foundation of health is a deep molecular genetic study of the microbiome . Unlike outdated cultures for dysbacteriosis, modern genetic and metabolomic analysis (offered by Ediens) allows:

Identify your enterotype: The group of bacteria that dominates your gut and determines your response to proteins, fats, or carbohydrates.
Assess species balance: Calculate the Shannon index (diversity of species) and the Pillow index (evenness of their distribution).
Identify the Firmicutes/Bacteroidetes ratio: A key marker responsible for the tendency to accumulate excess weight and metabolic syndrome.
Analyze metabolites: See exactly which short-chain fatty acids (SCFAs) your microbes are producing.

A comprehensive assessment of your gut, oral, or skin microbiome provides a comprehensive picture of what's going on in your body at the cellular level.

4. Biocode4U Meal Plan: Food and Drink as Medicine

After receiving the results of genetic testing, the patient is not left alone with complex numbers. Understanding that the microbiome is restored mainly through food, Ediens has developed a unique IT information system for personalizing the diet.

The Biocode4U nutrition plan is not just a standard diet. This selection is based on the obtained microbiome analysis and the client's individual profile. It involves adjusting the microbiome through the use of personalized nutrition, which is calculated according to the author's developed algorithm.

This algorithm uses huge databases of the effects of various biologically active substances of plants on microorganisms. It analyzes:

Genetic passport of the microbiome.
Biochemical blood test (not older than 1 month).
A detailed questionnaire (diagnoses, food allergies, physical activity, stress level).

As a result, artificial intelligence (under the supervision of medical experts) forms a menu in which traditional local products act as ideal prebiotics exclusively for your bacteria. You get a clear list of products that treat your body and those that provoke inflammation and bloating. If serious dysbiosis is diagnosed, the Biocode4U niche pharmabiotics line is connected to the diet plan: Targeted Pharmabiotics Line (for example, "Gut Harmony" for the intestines or "Metabolic Calm" for stress relief).

Conclusions

Summer heat is a test for our immunity and digestion. Sugary drinks with artificial sweeteners only increase stress, destroying our beneficial microflora. In contrast, berry water, matcha, vegetable smoothies and cold herbal teas are excellent sources of polyphenols and fiber that nourish our microbiome. However, to achieve true, long-term health, intuitive drink choices are not enough. Innovative technologies of molecular genetic research of the microbiome and the use of a smart algorithmic nutrition plan Biocode4U allow you to turn every sip and every meal into a powerful biohacking tool that purposefully restores your internal balance, prolongs youth and active longevity.

Short questions and answers (Q&A)

1. Why are artificial sweeteners in diet summer drinks bad for your stomach? Answer: Artificial sweeteners (such as aspartame) are not absorbed by the body's cells, but are rapidly metabolized by bacteria. They increase blood sugar levels, cause systemic inflammation, and stimulate the growth of unwanted, opportunistic enterobacteria in the gut microbiome, leading to dysbiosis and bloating.

2. What ingredients in summer drinks do our beneficial bacteria love the most? Answer: Beneficial microorganisms (commensals) most need prebiotics (dietary fibers, such as pectin from vegetables or apples) and polyphenols (anthocyanins from berry extracts, matcha green tea, nettle). These substances stimulate the growth of lacto- and bifidobacteria and help them produce short-chain fatty acids to protect the intestinal epithelium.

3. What is a microbiome study and how does it differ from a regular culture? Answer: A traditional culture (for dysbiosis) can only detect a tiny fraction of the microbes that survive in a test tube. A genetic study of the microbiome (NGS sequencing) determines the DNA of all bacteria in the intestine. It reveals your enterotype, species biodiversity (Shannon index), Firmicutes/Bacteroidetes ratio (prone to obesity), and metabolic profile of the flora.

4. How does the Biocode4U algorithmic Nutrition Plan from Ediens work? Answer: The Biocode4U Nutrition Plan is an individual diet created by a proprietary IT algorithm based on a genetic analysis of your microbiome, blood biochemistry, and a detailed questionnaire. Instead of universal diets, the system selects local foods and drinks so that their active substances work as targeted prebiotics, treating your specific diseases and eliminating the deficiency of beneficial bacteria.
