With the onset of summer, we often fall into gastronomic fanaticism: we try to eat as many fresh gifts of nature as possible to saturate the body with vitamins and lose excess weight. However, gastroenterologists and microbiologists every summer record a surge in complaints of bloating, cramps, heaviness and discomfort in the abdomen after eating seemingly completely healthy food. Modern 4P medicine proves that we feed not only ourselves, but also our microbiome - a giant ecosystem consisting of 38 trillion microorganisms. It is their composition that determines whether a summer salad will turn into energy or a source of pain.

In this article, we will analyze in detail why fiber needs caution in the summer, which vegetables are the best choice for the microbiome (in particular, zucchini, cucumbers, and greens), why berries are better than sweet fruits, and why the ideal seasonal foods for the intestines can only be selected based on individual tolerance.

Fiber in the Summer: Why More Isn't Always Better

For the microbiome to be healthy, it needs fiber. Our intestinal bacteria use plant fiber as the main substrate for life and reproduction. Current medical recommendations in the United States and Europe suggest that a healthy person should consume 28 to 40 grams of dietary fiber daily. At the same time, scientists who study the microbiome in depth conclude that for ideal balance, we need to eat even more than 50 grams per day.

However, the reality is that the diet of a modern person barely gets 15 grams of fiber. In winter and spring, our microflora "starves" on ultra-processed foods. When summer comes and we abruptly introduce large amounts of greens, salads, and raw vegetables into the diet, the unprepared intestine undergoes shock. People who suddenly start eating a lot of plant-based foods instantly experience bloating and stomach aches, because the bacteria that can break down complex carbohydrates are in short supply. Therefore, it is necessary to change the diet very gently, not radically, introducing new products in microdoses over several months so that the microbes and the intestine can adapt .

Greens, zucchini, cucumber and tomatoes are ideal vegetables for the microbiome

If you choose vegetables for your microbiome without fanaticism, you should pay attention to products with a high water content, soft fiber, and a low glycemic index. They do not provoke rapid fermentation processes.

Zucchini, cucumbers and tomatoes: These vegetables are an excellent source of indigestible dietary fiber that passes through the colon. They act as natural enterosorbents, affecting the quantitative and qualitative composition of microorganisms, helping to gently cleanse the intestines and relieve inflammation. In addition, they are low in sugar, which reduces the risk of flatulence.
Leafy greens: Spinach, arugula, parsley, and a variety of salads are not just vitamins. Leafy greens contain a type of sugar (sulfoquinovose) that specifically promotes the growth of healthy, protective gut bacteria.

To ensure that summer greens are perfectly digested even in sensitive intestines, the Ukrainian biotech company Ediens, together with the Zelen'Ok brand, offers an innovative solution - " The First Microbiome Salad " . The essence of biohacking is that a special sachet with live starter bacteria is added to the mix of fresh greens. By mixing them before consumption, you allow these helpful bacteria to instantly activate and break down tough fiber right in your plate and stomach, completely eliminating the risk of bloating.

Berries instead of sweet fruits: be careful with FODMAPs

In the summer, many people try to replace sweets with fruits, consuming kilograms of watermelons, peaches, apples and mangoes. However, for people with a disturbed microbiome (dysbiosis), such sweet fruits are dangerous. They are rich in simple sugars and fructose (FODMAP substances). If you have a predominance of pathogenic flora or Candida fungi , they will instantly react to such food. Excess sugar will cause gas-forming microflora to rapidly "bloom" and multiply, which will lead to acute fermentation and pain .

Therefore, doctors advise to shift the focus to berries. Blueberries (blueberry tall), blueberries, raspberries and blackberries have a low glycemic index, and the intestinal microbiota loves everything that has such a low index . Berries are rich in polyphenols, which act as powerful prebiotics, stimulating the growth of bifidobacteria and suppressing inflammatory processes in the body.

The healthy eating trap: individual tolerance

The main revolutionary discovery of 4P medicine is that there is no universal "healthy" diet. If you give the same apple to different people, they will react differently, and their bodies will receive different amounts of nutrients and energy . It all depends solely on your individual microbial composition.

Individual tolerance to foods is dictated by the bacteria that dominate your gut. For example, your love for raspberries and your ability to digest them perfectly may be due to the presence of Klebsiella bacteria (which, within normal limits, play a regulatory role). If this bacteria is absent, the berry may seem too sour or cause discomfort. Another example is dairy and fermented milk products. If your enterotype is dominated by bacteria of the genus Ruminococcus and there is a lack of mucin-degrading bacteria (such as Akkermansia ), regular milk or cheese will cause severe bloating, as the microbes will start fermenting it instead of properly breaking it down.

This is why so-called "intuitive eating" is often a fallacy. We're not feeding ourselves, we're feeding microorganisms, and they're the ones who are telling us, "I want this, I want a sweet, I want a bun ." As long as the microbiome is out of balance, it will force you to eat what's good for the pathogens, not you.

Ediens Solutions: From Blind Diets to Exact Science

To ensure that your summer diet brings only energy, Ediens offers a comprehensive approach based on 37 years of clinical research:

Deep diagnostics (NGS): Instead of guessing whichseasonal gut foods are right for you, the company conducts precise molecular genetic analysis of your microbiome. This allows you to see your enterotype, species diversity, and the ratio of beneficial to pathogenic bacteria.
Personalized nutrition plan : Based on the data received, a mathematical IT algorithm calculates a completely individual diet. The algorithm selects precisely those local vegetables, berries and herbs that will be the perfect fertilizer exclusively for your protective bacteria.
Targeted correction with pharmabiotics: If dysbiosis has already led to chronic bloating, allergies, or constipation, regular store-bought yogurts won't help. Ediens has developed a new generation of niche biologics — pharmabiotics (for example, " My Second Brain. Intestinal Microbiome " ) that specifically suppress pathogenic flora, restore mucous membranes, and normalize digestion in just 14 days.

Conclusion: Summer variety of fruits and vegetables is a great tool for recovery, but it should be used without fanaticism. A sharp increase in fiber or excess fructose from watermelons and apples can "break" an unprepared intestine. Bet on safe vegetables (zucchini, cucumber, greens) and berries with a low glycemic index. And in order for nutrition to be truly therapeutic, trust evidence-based medicine and individual microbiome analysis from Ediens, which will tell you exactly what your "superorgan" needs.

Short questions and answers (Q&A)

1. Why can a sharp increase in fiber in the summer cause acute bloating? Answer: Most modern people have a diet low in fiber. Because of this, bacteria that can break down complex carbohydrates are suppressed or die. If you suddenly start eating kilograms of raw vegetables and herbs in the summer, your intestines will not be able to digest them. Pathogenic bacteria will begin to multiply, which will cause fermentation, severe bloating and pain. Fiber should be introduced in microdoses in the summer.

2. What vegetables are the safest and most beneficial for the microbiome in the summer season? Answer: It is best to choose vegetables with a high water content and soft fiber, but low in sugar. Zucchini, cucumbers, tomatoes and leafy greens (spinach, arugula) are ideal. They serve as an excellent prebiotic and enterosorbent for beneficial bacteria, without causing excessive fermentation in the colon.

3. Why do microbiologists advise choosing berries over sweet fruits? Answer: Sweet summer fruits (watermelon, mango, sweet apples, pears) contain a large amount of fructose. In dysbiosis, this sugar becomes food for yeast fungi and pathogenic bacteria, causing their rapid reproduction and flatulence. In contrast, berries (blueberries, raspberries, cranberries) have a low glycemic index, which is ideal for healthy intestinal flora, and contain powerful antioxidants.

4. How do I know which seasonal gut foods are right for me? Answer: There are no universal diets, as individual tolerance to foods depends on your unique microbiome composition. To find out for sure, Ediens offers a molecular genetic analysis of the gut microbiome (NGS). Based on this test, a mathematical IT algorithm will create your personalized nutrition plan, which will include only those summer vegetables and fruits that will heal your body.
