Fermented Vegetables for the Animal-Based Diet: Health Benefits

Introduction to Fermented Vegetables in Animal-Based Diets

Fermented vegetables have undergone fermentation that involves the growth of beneficial bacteria. Controlled microbial growth and enzymatic action convert food components to produce these vegetables. They are a source of lactic acid bacteria with probiotic characteristics such as lowering cholesterol. It extends the shelf life and reduces food wastage.

The animal-based diet is a low- or no-carb diet focusing on animal-based foods, such as meat, fish, dairy, eggs, and organs. It eliminates all plant-based foods like fruits, vegetables, grains, and nuts. Animal-based diets are rich sources of protein, fat, vitamins, and essential amino acids. 

Importance of Fermentation:

Fermentation is a natural process that uses bacteria and yeast to produce acids or alcohol from carbohydrates like sugar and starch. Due to the alcohol or acids, fermented foods have a unique zest and acidity. The alcohol or acids also serve as a natural preservative. Additionally, fermentation enhances the development of probiotics, which are beneficial bacteria. Probiotics have beneficial effects on heart and digestive health and enhance immunological functions.

Fermentation also improves the food's flavour, texture, and nutritional content. It is beneficial in preserving food, increasing shelf life, and enhancing taste. Additionally, fermentation increases the nutritional content of foods and reduces the amount of toxins and pathogens, making them safer to consume. However, improper fermentation techniques can produce harmful compounds such as biogenic amines.

How Do Fermented Vegetables Complement an Animal-Based Diet?

Fermented vegetables complement an animal-based diet high in protein and improve digestion and nutrient absorption by increasing the number of beneficial bacteria. However, an animal-based diet primarily focuses on animal products; adding fermented vegetables is beneficial. Fermented vegetables, like sauerkraut or kimchi, offer probiotics and enzymes to improve gut health in following an animal-based diet (rich in protein and fats). Fermented vegetables' acidity and nutrient profile also help digestion and reduce inflammation to suit animal-based diets.

A Brief History of Fermentation in Human Diet.

Pasteur was the first who discovered the role of microorganisms in fermentation. Humans used the fermentation process in ancient times to preserve their food and enhance its quality. In northern Africa, the fermentation of milk takes place in animals such as camels, sheep, goats, and cattle to produce yoghurt. Similarly, in China, vegetable fermentation was common in 1300 BC. 

Many researchers in Neolithic China also reported evidence of fermented alcoholic beverages made from honey, fruits, and rice. Fermented vegetables have a long history in the human diet, as evidenced by the different European and Asian cultures incorporating them into their traditional diets. Since ancient times, humans have learnt to use fermentation for personal use, such as in food, medicine, and fuel. 

The article explores the benefits and incorporation of fermented vegetables into an animal-based diet. It focuses on the fermentation process, its health benefits, and how it can enhance a diet's digestive and nutritional value while focusing on animal-based food items.

Understanding Fermentation

Fermentation is a biological and chemical process that breaks organic compounds into simpler substances with the presence of bacteria or yeast, such as carbohydrates, into acids or alcohols without oxygen. 

Types of Fermentation:

There are three types of fermentation.

• Lactic acid fermentation
• Alcoholic fermentation
• Acetic acid fermentation

Lactic acid and alcoholic fermentation are the most common foods that play important roles in preserving food for a longer time, enhancing its taste, and making it more digestible. 

Lactic Acid Fermentation:

It is a metabolic process that produces energy and lactic acid. It is an anaerobic process that involves lactic acid bacteria (Lactobacillus and Leuconostoc) to break down sugar into lactic acid. The lactic acid inhibits the growth of bacteria and acts as a preservative by lowering the pH. It provides many health benefits, such as improving gut health and boosting the immune system. Lactic acid fermentation produces these lists of foods.

• Kimchi
• Yoghurt
• Sauerkraut
• Pickled vegetables
• Sourdough
• Fermented vegetables

Alcoholic Fermentation:

Alcoholic fermentation, or ethanol fermentation, converts sugars into alcohol and carbon dioxide. Yeasts are involved in alcoholic fermentation, which occurs without oxygen. Alcoholic fermentation produces these lists of foods.

• Bread making
• Beer
• Wine
• Cider 
• Rum

Acetic Acid Fermentation

Acetic acid fermentation, or vinegar fermentation, involves bacteria converting alcohols or ethanol into acetic acid. The enzyme involved is alcohol dehydrogenase (ADH), which oxidises ethanol to acetaldehyde. People commonly use acetic acid fermentation to make food materials like vinegar. 

Role of Probiotics and Beneficial Bacteria:

Probiotics are beneficial microorganisms that provide many health benefits. They play an essential role in healing intestinal ulcers and infected cutaneous wounds. Probiotics are also linked to other benefits, such as improving digestion, contributing to vitamin production, supporting immune function, reducing inflammation, and enhancing the metabolism and absorption of nutrients and certain medicines.

Usually, probiotics coexist with yeasts, viruses, bacteria, and protozoa to provide unique characteristics. One unique property is that they can survive stomach acid and reach the intestines, making them safer for consumption. Eliminating excess harmful bacteria is beneficial for maintaining a microbial balance.

Bacteria such as Lactobacillus, Bifidobacterium, and Saccharomyces boulardii are the most common types of probiotics. They are present in the gut, mouth, skin, lungs, vagina, and urinary tracts. 

Nutritional Changes during Fermentation:

Fermentation can change foods' macronutrient composition, affecting the amounts of proteins, lipids, and carbohydrates. For example, microorganisms like bacteria, yeasts, and moulds break carbohydrates down into main sugars during fermentation, producing organic acids and alcohol. Due to metabolic activity, certain foods' calorie and nutritional value may also alter. 

Similarly, a large proportion of sugars undergo metabolism during alcoholic or lactic acid fermentation. However, the energy produced by the fermentation of sugars to either ethanol or lactic acid is only 2 mol ATP/mol hexose. While microbes only extract ~5% of energy (as ATP), humans absorb the remaining energy from ethanol/lactic acid.

Benefits of Fermented Foods:

Fermented foods provide many health benefits, including

• Improves gut functioning: As fermented foods contain probiotics, they strengthen the gut microbiome and improve digestion. 
• Lowers the risk of infection: Probiotics protect against pathogens or harmful bacteria that cause infections. 
• Increases food shelf life: Fermentation increases the shelf life of food by producing acids, alcohols, and gases. These inhibit the growth of bacteria and other organisms.
• • Enhances food flavour: fermentation improves the food's overall taste and flavour. These foods produce various metabolites from carbohydrates, proteins, and fats, which contribute to a food's aroma, taste, and flavour.
• Increases nutrient availability: The fermentation breaks down antinutrients (like phytic acid) into calcium, magnesium, and iron to make them more bioavailable. It also produces beneficial compounds like B vitamins, probiotics, and enzymes, which support digestion and gut health.
• Lowers the risk of CVD: Fermented foods are well known to reduce inflammation and lower the risk of cardiovascular diseases, including hypertension and arrhythmias.
• Improves blood pressure: Fermented foods are beneficial in hypertensive patients because they lower blood pressure by blocking the enzymes that raise it.
• Controls blood sugar and cholesterol levels: Fermented foods also improve blood sugar and cholesterol levels by increasing fibre and probiotics.
• Play a role in weight management: Probiotic foods can help with weight loss by reducing inflammation and maintaining gut health. For example, fermented blueberries, apples, mulberries, and pears decrease fat accumulation, promote lipid metabolism, and reduce body weight.
• Improves mood: Fermented foods containing probiotics improve mood by changing gut microbes as they affect brain health. These foods support gut bacteria, which increases serotonin levels and boosts mood.
• Strengthens the immune system: Fermented foods break down sugar and produce compounds that boost the immune system. 
• Improves lactose digestion: Fermented food improves lactose digestion and benefits lactose-intolerant people. These foods break down the lactose into simpler sugars to make it easier for digestion.
• Improves bone health: Fermented foods provide nutrients that help build and maintain bone density by modifying gut microbiota to improve bone health.

Lactic acid fermentation preserves food by lowering its pH and preventing the growth of spoilage-causing bacteria. The NIH reported that lactic acid has antimicrobial properties produced during fermentation that ensure food safety.

The NIH also highlighted that fermentation enhances the amount of bioactive compounds, like vitamins and antioxidants. It improves the digestion of complex carbohydrates and proteins. For example, sauerkraut and kimchi contain higher levels of vitamins B and C after fermentation.

Types of Fermented Vegetables Suitable for Animal-Based Diet

Below are some fermented vegetables with additional nutrients that provide many benefits and are suitable for animal-based diets.

Sauerkraut

You make sauerkraut by mixing shredded cabbage with salt and allowing it to ferment with lactic acid bacteria. It is rich in nutrients and contains high levels of fibre, iron, probiotics, and vitamins C and K. Consuming sauerkraut increases the health of the digestive system by optimising gut flora and balancing gut microbes. 

It is a low-calorie food that primarily contains carbohydrates. The cabbage in sauerkraut also provides antioxidants that help reduce inflammation and oxidative stress in the body. People can also consume sauerkraut with sausages to add a refreshing meal to the dish while improving nutrient absorption.

Combining sauerkraut with meat is a healthy option that is easily digestible and is high in nutrition. It also enhances the nutritional profile by adding vitamins, minerals, and antioxidants, contributing to a balanced meal.

Kimchi

Kimchi is another traditional Korean dish of salted and fermented vegetables with a spicy and tangy taste. It is rich in probiotics, fibres, vitamins, and minerals. It is beneficial in supporting the immune system and reduces inflammation. Kimchi is also known for providing the following benefits:

• High in vitamins A, B, and C 
• Provides antioxidants.
• Slower the ageing process
• Reduces inflammation
• Strengthens immune systems
• Prevents yeast infections
• Beneficial in weight loss
• Supports heart health 

You can also combine kimchi with roasted or grilled beef to enhance its flavour and nutritional benefits. Usually, people pair it as a side dish with grilled beef or pork to enhance the meal's spicy, tangy flavour. 

Pickles

Vegetable pickles are another probiotic source for fibre, vitamin K, and antioxidants. It also contributes to improved digestion. Foods such as pickled cucumbers, carrots, or jalapeños taken with meat reduce acidity and balance the flavour. The benefits of fermented pickles include

• Improved digestion
• Boasts gut health.
• Aids in weight loss
• Boost immunity
• Reduces risk of cancer

People usually consume pickles with every meal, such as pickles taken with pork sandwiches, to add a tangy, refreshing, and nutrient-rich taste.

Fermented Garlic and Onions

Fermented garlic and onion provide many potential health benefits. 

• Improved digestion
• Boasts an immune system
• It provides anti-inflammatory and antioxidant properties.
• Improves CVD health

Garlic is also a natural antibiotic and lowers cholesterol levels. People use it to flavour roasted meats such as lamb or beef, while fermented onions enhance the umami flavour of stews, meat, or grilled chicken. People frequently consume fermented garlic to marinate beef to enhance flavour and nutrient absorption.

Other Fermented Vegetables (Carrots, Beets)

Fermented carrots and beets provide excellent sources of fibre, beta-carotene (carrots), and nitrates (beets) to support cardiovascular health. They are rich in probiotics and enhance digestion when consumed with other meals. A colourful, tangy slaw meal with fermented carrots and beets offers a nutritious and flavourful alternative to grilled chicken or steak.

Therefore, fermented vegetables provide many benefits, like kimchi, sauerkraut, and pickles, when consumed with meals and improve taste, digestion, and nutritional balance.

Comparison of Nutrients in Raw and Fermented Vegetables

Nutrients	Raw Vegetables	Fermented Vegetables
Vitamin C	High in most raw vegetables like kale and cabbage	Slight decreases due to fermentation
Vitamin K	High-leafy greens such as kale and spinach	Often remains stable or increases slightly
Fibre	High in raw vegetables such as carrots and cucumbers	Also high but slightly reduced
Probiotics	None	Rich in beneficial bacteria (e.g., Lactobacillus)
Antioxidants	High in raw such as broccoli and spinach	Antioxidant levels often increases in sauerkraut and kimchi

Nutritional Benefits of Fermented Vegetables in Animal-Based Diets

Fermented vegetables provide a unique combination of nutrients and probiotics and ensure digestive health in addition to animal-based diets. These are some benefits of fermented vegetables and their role in supporting gut health and immunity.

Enhanced Nutrient Absorption

Fermentation is a natural process that enhances the bioavailability of essential nutrients. This process breaks down complex compounds to make them absorbed for vitamins, minerals, and other nutrients, which is beneficial in animal-based diets. The bioavailability of components in fermented vegetables is higher than in pre-processed products. The NIH shared that nutrients like B vitamins, iron, and magnesium are more bioavailable in fermentation, supporting overall health.

Probiotic Content

Fermented vegetables are rich in probiotics due to the presence of beneficial bacteria that promote gut health. It is essential for proper digestion, nutrient absorption, and immune functions. Probiotic-rich fermented vegetables such as sauerkraut and kimchi improve digestion and also boost the immune system.

Vitamin and mineral boosts

Fermentation increases the vitamins and minerals in vegetables. For example, fermented vegetables also contains some levels of B vitamins, including B12 (primarily found in animal-based diets). However, some fermented vegetables do not contain vitamin B12 unless fortified. It also increases the amount of calcium, magnesium, and potassium minerals, which support body functions such as bone health, muscle function, and nerve transmission.

Digestive Health

Another benefit of fermented vegetables in animal-based diets is improving digestive health. High-protein diets are difficult to digest and can cause bloating or constipation. However, the probiotics and enzymes in fermented vegetables help break complex protein and fat into simpler substances, making digestion smoother and more efficient. Additionally, the fibre content in fermented vegetables supports regular bowel movements.

Antioxidant Properties

The fermentation process enhances antioxidant properties through a microbial hydrolysis response. It increases the amount of flavonoids and phenolic compounds, such as vitamin C and phenols. These antioxidants neutralise harmful free radicals and reduce inflammation. In an animal-based diet, oxidative stress is higher due to a high intake of protein and fats, but fermented vegetables protect against these harmful bacteria.

The National Institute of Health (NIH) reported that probiotics are important for gut health. The researchers concluded that consuming foods high in probiotics ensures more balanced gut flora and is less prone to digestive issues. Studies have also demonstrated that probiotics enhance immune function. 

Integrating Fermented Vegetables into an Animal-Based Diet

Meal Planning Strategies:

You can add fermented vegetables to snacks, sandwiches, and even meals in your diet. Fermented foods contain living organisms; people can also add them to recipes after cooking a whole meal, such as garnishing. These are nine simple ways to add fermented foods, especially vegetables, to the diet.

1. Consume a little kraut or kimchi for breakfast with burritos or scrambles.
2. Slide between sandwiches and lunch wraps with a forkful.
3. Add kimchi or sauerkraut to grilled cheese sandwiches.
4. Consume tofu soup as a snack with fermented miso paste.
5. In coleslaw and potato salad, add sauerkraut as fermented food.
6. Stir fermented vegetables into sauces with salmon, tuna, or crab-like fish cakes.
7. Add kimchi as a fermented food, rich in probiotics, in stir-fries and rice bowls.
8. Consume green salads with fermented vegetables.
9. Also, add kimchi or kraut while eating hot dogs and burgers.

Recipe Ideas for Fermented Foods:

As fermented foods are beneficial to consumers, here are some recipe ideas for choosing a healthy option. Use sterile tools and follow tested recipes to avoid contamination.

• Kimchi Stir-Fry with Beef: A stir fry with thinly sliced beef and kimchi adds a spicy and tangy flavour. Add a fried egg for extra richness.
• Pork Tacos with Fermented Salsa: Take slow-cooked pulled pork and top with fermented salsa for a zesty contrast.
• Grilled Chicken with Sauerkraut: Pair juicy grilled chicken thighs with a side of sauerkraut for a flavour-packed meal.
• Lamb Stew with Pickled Onions: Stewed lamb with a garnish of pickled onions.

Some snack options include sandwiches made with fermented foods.

Here are some recipes for fermented meals, complete with ingredients and instructions.

1. Homemade Kimchi: Lacto-fermentation creates this Korean staple of salted and fermented vegetables. It is high in fibre, boosts immunity, promotes heart health, and reduces inflammation.

Ingredients:

• Napa cabbage (1 medium, about 2 pounds)
• Salt (¼ cup iodine-free salt)
• Garlic (1 tbsp grated garlic, 5-6 cloves)
• Ginger (1 tsp peeled fresh ginger)
• Sugar (1 tsp granulated)
• Fish sauce or shrimp paste (2 tbsp fish sauce with 3 tbsp water)
• Gochugaru (Korean red pepper flakes)
• Korean radish (8-ounce daikon radish, peeled and cut)

Recipe: 

• Cut the cabbage lengthwise through the stem into quarters. Cut the cores from each piece. Cut each quarter crosswise into 2-inch-wide strips.
• Place the cabbage in a large bowl and sprinkle with the salt. Rub the cabbage with your hands until it softens. Add enough water to cover the cabbage, place a plate on its top, weigh it down with a heavy object, such as a can or jar of beans, and leave it for one to two hours.
• Drain the cabbage in a colander for 15 to 20 minutes after rinsing it thrice under cold water. Meanwhile, prepare the spice paste.
• • To make the spice paste, clean and dry the salt bowl. Stir in a smooth paste after adding the fish sauce, shrimp paste, sugar, ginger, and garlic. Add the gochugaru and stir until it's ready, using 1 tablespoon for mild and up to 5 tablespoons for spicy.
• Mix the vegetables and spice paste to squeeze the remaining water from the cabbage. After mixing, add the radish and scallions.
• • Using your hands, cover the vegetables completely with the paste. 
• Put the kimchi in a one-quart jar. The kimchi should have at least 1 inch of space at the top, so press down until the brine (the liquid) rises to cover the vegetables. Seal the jar properly.
• To catch overflow, place a dish or plate below the jar. Keep the jar out of direct sunlight and at room temperature for one to five days. After that, you can see any bubbles inside the jar and brine leaking from the lid.
• Open the jar and use a clean finger or spoon to press down on the vegetables to keep them in the brine (liquid). Check the kimchi once a day. You should also taste a little now! Put the jar of kimchi in the fridge once it is sufficiently ripe for you to enjoy. Now it's ready to consume, and you can take it after another week or two.

2. Korean Beef Rice Bowl

Portion Sizes and Frequency of Fermented Food: How Much to Consume

Aspect	Recommendation
Portion Size	Start with 1-2 servings per day and gradually increase the intake.
Frequency	2-3 times per day
Starting Amount	Begin with smaller portions to adjust to the flavors
Balance with Other Foods	Consume fermented vegetables with milder or fat-rich meats to balance flavors

How can I balance the strong flavours of fermented vegetables with meat?

Fermented foods have strong, acidic tastes. which dominate other ingredients. To balance its strong flavour, you can combine it with meat.

• Pair seasoned meats like roasted chicken or grilled steak (according to preference) with the fermented vegetables.
• Use herbs and spices like garlic, thyme, and rosemary to garnish both the meat and the fermented foods.
• Meats rich in fat, such as lamb or pork, can help balance the acidity of fermented vegetables and provide a more pleasant flavour combination.

How do you store fermented vegetables to maintain quality?

Storing fermented vegetables is essential to maintaining the quality of food and preserving its taste. Long-term storage of fermented foods involves more than just keeping your kitchen cool. Below are some guidelines for ensuring the safety and flavour of fermented foods.

1. Choose a container with a tight lid for fermented vegetables.
2. Submerge the fermented food completely in liquid or brine.
3. Store in a cool, dark place, such as a cupboard, pantry, or cellar, at a cool temperature.
4. After fermenting the vegetable, refrigerate it for extended shelf life to use it for months or even years.
5. Label the jar with the types of ferment and the start date on each jar.
6. Check regularly to identify any potential issues early.
7. Avoid metal corrosion and use plastic lids or place parchment paper between the ferment and metal lids.
8. Use a proper salt ratio to create a safe environment for fermentation and prevent spoilage.
9. Refrigerate fermented foods for long-term storage.
10. Consider small jars or containers to lower the risk of contamination.

Common Misconceptions About Fermented Vegetables in Animal-Based Diets

There are many misconceptions about fermented vegetables in an animal-based diet. Let’s identify these myths and provide factual information for those who are incorporating fermented foods into their diet.

Myth 1: Fermented vegetables are high in carbohydrates.

Explanation: Raw vegetables contain carbohydrates, but the fermentation process reduces the carb content. During fermentation, beneficial bacteria consume sugars and starches, which lowers the overall carbohydrate content of the vegetables. For example, fermented cabbage (sauerkraut) has a lower carbohydrate content than raw cabbage, which makes it suitable for people following a low-carb diet. 

Myth 2: Fermented foods are always high in salt.

Explanation: While traditional fermentation uses salt, there are numerous low-sodium fermentation techniques available. For instance, one can reduce the salt concentration in brine by using salt substitutes. People can also use naturally low-sodium vegetables to produce fermented vegetables that are both healthy and tasty without excessive salt. However, one should be carful while using salt substitute because altering salt ratios can cause spoilage or foodborne illness.

Myth 3: Fermented vegetables can cause bloating.

Explanation: Some individuals complain of bloating if they are new to fermented foods. However, it is not true because proper fermentation methods significantly reduce this risk. Proper fermentation breaks down fibres and oligosaccharides in vegetables, which cause bloating and digestive discomfort. Starting with small amounts of fermented vegetables and increasing them slowly allows the digestive system to reduce bloating issues.

Myth 04: All fermented foods are probiotic-rich.

Explanation: Not all fermented foods are rich in probiotics. Some fermented vegetables also go through other processes, such as pasteurisation, which kills live bacteria. However, other fermentation methods focus on the richness of flavour, except when cultivating probiotic bacteria. So, people can also consume unpasteurised and raw-fermented foods to benefit from probiotics.

Myth 05: Fermented vegetables are not suitable for carnivores:

Explanation: Carnivorous diets especially focus on animal products. However, you can include fermented vegetables in moderation as a source of beneficial bacteria that support gut health. Fermented vegetables are beneficial to balance digestion, improve nutrient absorption, and provide enzymes for breaking down proteins from animal foods. 

Challenges and considerations when incorporating fermented vegetables

These are some potential challenges and considerations that may arise when incorporating fermented vegetables into your diet.

Digestive Adjustments:

Dietary adjustment while starting fermented vegetables is the common challenge. For those who started consuming probiotics, there may be initial discomfort, such as bloating or gas. However, the bloating disappears when the body adapts with the increased intake of beneficial bacteria. To overcome this, it is recommended to start with small portions and gradually increase the amount of fermented foods. It ensures the digestive system adjusts the probiotics properly. 

Taste Preferences:

Fermented vegetables usually have a strong, tangy, and sour flavour. The taste may be unfamiliar or unpleasant for some individuals. However, it is essential to manage taste preferences, especially for those who take fermented foods for the first time. To overcome this challenge, one can start experimenting with different types of fermented vegetables, such as kimchi, sauerkraut, or pickles, to become familiar with flavours that suit their palates. Additionally, adding fermented vegetables to favourite meals, like salads or sandwiches, also helps in the transition to these flavours.

Availability and Accessibility:

Living where high-quality fermented veggies are not easily accessible presents another challenge. Naturally, fermented choices may not always be available in stores that provide fermented products. People can access these fermented vegetables from local food stores or farmers' markets. They can also ferment vegetables at home. DIY fermentation ensures a fresher product and gives you more control over the quality of the components.

Cost Considerations:

Living where high-quality fermented veggies are not easily accessible presents another challenge. Naturally, fermented choices may not always be available in stores that sell them. However, people can access these fermented vegetables from local food stores or farmers' markets. They can also ferment vegetables at home. DIY fermentation ensures a fresher product and gives you more control over the quality of the components.

Storage and Shelf Life:

Proper storage of fermented vegetables is important for maintaining probiotic benefits. Proper storage prevents the fermented vegetables from losing their taste or potency. Store fermented vegetables in a cool, dark place and refrigerate once opened. To overcome this, it is recommended to buy smaller portions if you consume them infrequently or properly seal and refrigerate homemade fermented foods to extend their shelf life.

Practical Tips for Incorporating Fermented Vegetables in Your Diet

Fermented vegetables are a great way to enhance your gut health, improve digestion, and increase the flavour of your meals. Here are some tips for easily incorporating them into the diet.

• Start Slowly: Begin with small portions like a tablespoon of sauerkraut or kimchi to allow your digestion to adapt.
• Pair with Protein: Combine fermented vegetables with meats, tofu, or beans for balanced, nutrient-rich meals.
• • Use as a condiment: add a spoonful of fermented vegetables to sandwiches, wraps, or burgers for extra flavour.
• • Experiment with recipes: Incorporate fermented vegetables into salads, stir-fries, or soups to find your favourite combinations.
• Homemade Fermentation: Try making your own sauerkraut or kimchi at home with simple ingredients like cabbage and salt. For example, kimchi made in soup, meat, or pork is the best home-made fermented dish to consume.
