Introduction
If you have ever reached for a crisp, tangy gherkin straight from the jar, you might have wondered whether this sour kitchen staple is doing anything positive for your digestive tract. With gut health firmly in the spotlight across the UK, everyday fermented foods have gained widespread attention. From artisan sauerkraut and kimchi to traditional pickled cucumbers, supermarket shelves and pantry cupboards are filled with tangy options claiming to support the microbiome.
Yet when asking if pickles are good for gut health, the answer is rarely a straightforward yes or no. The reality depends entirely on how that pickle was made, what ingredients sit in the brine, and how your individual body handles salt, acid, and active microbes. While genuine lacto-fermented pickles can deliver beneficial living bacteria directly to the digestive system, mass-produced vinegar pickles—the ones most commonly found in British supermarkets—offer an entirely different nutritional experience.
This guide explores the science behind pickled foods, breaks down the biological difference between fermentation and vinegar pickling, examines what these foods can and cannot achieve for your digestive system, and highlights important cautions regarding sodium and gastric irritation. Whether you are navigating persistent bloating, looking to enrich your dietary diversity, or simply curious about what goes into your digestive tract, understanding the mechanisms behind what you eat is an empowering first step. For broader background, our guide to what the gut microbiome is and why it matters offers useful context.
At Blue Horizon, our medical team advocates a calm, clinically responsible approach to digestive and overall wellness. We believe that no single food serves as a cure for chronic gut symptoms. Instead, sustainable health stems from seeing the complete picture: working with your GP first to rule out underlying clinical issues, maintaining thoughtful lifestyle and symptom tracking, and using targeted investigations when you need a clear snapshot of your internal biochemistry.
Understanding Pickles: Fermented vs Pickled
To understand the relationship between pickles and digestive wellbeing, we must first clear up a major source of culinary confusion. In everyday conversation, the word "pickle" is used as a broad umbrella term for any vegetable preserved in an acidic liquid. However, from a biological and nutritional perspective, pickles fall into two distinctly separate categories: fermented pickles and quick-pickled (vinegar) pickles.
The Science of Lacto-Fermentation
Traditional pickling is an ancient method of biological preservation known as lacto-fermentation. In this method, fresh vegetables—most commonly cucumbers, but also carrots, radishes, cabbage, or peppers—are submerged in a solution of clean water and unrefined salt (a saline brine), without any added vinegar.
The salt plays a dual role: it inhibits the growth of harmful spoilage bacteria and pathogens, while creating an ideal environment for salt-tolerant, beneficial microorganisms naturally present on the skin of the vegetables. The primary drivers of this transformation belong to the Lactobacillaceae family, including species such as Lactiplantibacillus plantarum, Lactiplantibacillus brevis, and Pediococcus pentosaceus.
Over several days to weeks at room temperature, these microscopic organisms consume the natural sugars present in the vegetable tissue. As they feed, they metabolise these carbohydrates into lactic acid, carbon dioxide, and various trace organic compounds. The continuous production of lactic acid lowers the pH of the brine, creating an acidic environment that preserves the vegetable, imparts a distinctive sour and umami flavour, and leaves the final product teeming with live, beneficial microbes known as probiotics.
Crucially, because authentic lacto-fermented pickles are not subjected to high-heat pasteurisation, these friendly bacteria remain alive and viable when you eat them.
Quick Pickling with Vinegar
By contrast, the overwhelming majority of jars sitting on ambient supermarket shelves across the UK are quick pickles, also known as vinegar pickles or fresh-pack pickles.
Rather than relying on time and microbial activity to generate acidity, the producer creates an instant acidic environment by submerging vegetables in an already acidic solution—typically distilled white vinegar, malt vinegar, or cider vinegar (acetic acid)—blended with water, salt, sugar, and flavourings like mustard seed, dill, or garlic.
To ensure these products can sit safely on ambient grocery shelves for months or years without spoiling, they are heated, sealed, and pasteurised. While this high-heat process effectively sterilises the jar and prevents microbial contamination, it also kills off any living microorganisms that were present on the fresh produce.
Key Takeaway: Vinegar pickles provide pleasant crunch, tart acidity, and vegetable micronutrients, but they do not contain living probiotic bacteria. If your primary goal is to introduce live cultures into your digestive system, you must look for unpasteurised, naturally fermented pickles preserved in saltwater brine.
How Fermented Pickles Support Gut Health
When naturally fermented, salt-brined pickles can serve as a supportive addition to a gut-friendly dietary pattern. The human gastrointestinal tract houses trillions of microorganisms, collectively referred to as the gut microbiome. This complex internal ecosystem plays an integral role in breaking down food, synthesising essential vitamins (such as folate and vitamin K), modulating the immune system, and maintaining the structural integrity of the intestinal lining.
Consuming genuine fermented pickles interacts with this ecosystem through several clear biological pathways. For practical ways to support digestion more broadly, see our guide to starting to improve gut health.
Delivering Live Probiotics to the Microbiome
The most widely discussed gut benefit of fermented pickles is their probiotic payload. Probiotics are defined as live microorganisms which, when administered in adequate amounts, confer a health benefit on the host.
When you consume raw, unpasteurised fermented pickles, a portion of the lactic acid bacteria can survive the journey through the acidic environment of the stomach and reach the small and large intestines. Once in the gut, these transient microbes:
- Compete with potentially harmful opportunistic microbes for nutrients and attachment sites along the mucosal lining.
- Produce antimicrobial compounds called bacteriocins that naturally suppress undesirable bacteria.
- Help maintain an optimal, mildly acidic pH within the colonic lumen, which supports native beneficial bacteria like Bifidobacteria.
While transient probiotic bacteria do not permanently colonise the gut in the long term, their regular passage through the digestive system can promote microbial diversity and support temporary balance, particularly during times of mild dietary disruption or stress.
Promoting Short-Chain Fatty Acid Production
During the fermentation process outside the body, bacteria break down complex plant fibres and simple sugars, generating organic acids such as lactic acid and acetate. When introduced into the gut, these compounds can serve as biochemical building blocks that cross-feed resident colonic bacteria.
These resident microbes further ferment dietary fibres to produce short-chain fatty acids (SCFAs), predominantly:
- Butyrate: The primary fuel source for colonocytes (the cells lining the wall of the large intestine), vital for maintaining gut barrier integrity.
- Acetate and Propionate: Organic acids that enter the bloodstream to support metabolic regulation, liver function, and systemic immune signalling.
A gut environment enriched with short-chain fatty acids tends to be associated with lower markers of local inflammation and better mucosal defense.
Bioavailability of Plant Polyphenols and Micronutrients
Cucumbers and other pickling vegetables naturally contain a variety of micronutrients and plant antioxidants, including beta-carotene (which the body converts into vitamin A), vitamin K, potassium, and phenolic compounds.
The biological process of fermentation acts as a form of gentle pre-digestion. Microbial enzymes break down tough plant cell walls and degrade anti-nutritional factors (such as phytates), which can otherwise bind to essential minerals. This enzymatic breakdown can increase the bioavailability of the vegetable's native antioxidants and vitamins, making it easier for the small intestine to absorb and utilise these nutrients.
Furthermore, the fermentation of specific vegetables produces natural plant metabolites, such as alkyl catechols, which preliminary cellular research suggests may help activate internal antioxidant response pathways, protecting delicate mucosal cells against oxidative stress.
What Pickles Cannot Do: Managing Digestive Expectations
While the nutritional mechanisms of fermented pickles are fascinating, it is vital to maintain realistic expectations regarding what any single food can achieve. In an era of wellness trends and sensationalised dietary advice, fermented foods are sometimes framed as an instant cure for complex gastrointestinal complaints.
A responsible medical perspective requires looking at the limitations as well as the benefits.
Fibre Content and Prebiotic Limitations
A thriving, resilient microbiome requires two primary components: probiotics (the living organisms) and prebiotics (the specialised, fermentable dietary fibres that feed those organisms).
While fermented pickles provide live cultures, standard pickling cucumbers are relatively low in prebiotic dietary fibre. A standard serving of pickled cucumbers provides only around one gram of dietary fibre. In comparison, foods such as slightly underripe bananas, cooked and cooled potatoes, oats, leeks, onions, garlic, and lentils provide substantially higher concentrations of prebiotic fibres like inulin, resistant starch, and fructooligosaccharides.

+-------------------------------------------------------------------+
Relying solely on pickles without consuming a broad spectrum of fibrous vegetables, legumes, and whole grains will leave your resident gut bacteria without the sustained fuel they need to thrive.
The Difference Between Dietary Support and Medical Treatment
It is crucial to understand that dietary additions like fermented pickles are general wellness supports, not clinical treatments. If you are experiencing persistent digestive symptoms—such as recurrent abdominal pain, persistent bloating, altered bowel habits (chronic diarrhoea or constipation), unexplained weight loss, or blood in your stool—eating fermented foods will not resolve the root cause.
These symptoms require formal clinical evaluation by a GP to investigate and rule out medical conditions such as:
- Coeliac disease
- Inflammatory bowel disease (such as Crohn's disease or ulcerative colitis)
- Irritable bowel syndrome (IBS)
- Small intestinal bacterial overgrowth (SIBO)
- Underlying hormonal imbalances, such as thyroid dysfunction, which frequently alters gut motility
Pickles can be part of a diverse, balanced diet, but they cannot replace standard medical care, clinical diagnostics, or evidence-based therapies.
Potential Downsides and Cautions
Although fermented pickles offer digestive advantages for many people, they are not universally suitable for everyone. Certain ingredients and biological properties can trigger side effects or exacerbate existing health conditions.
High Sodium Content and Blood Pressure
The most significant physiological drawback of all pickles—whether fermented or vinegar-based—is their exceptionally high salt content. Salt is an indispensable preservative in the pickling process; without sufficient sodium, safe lacto-fermentation cannot occur, and harmful moulds or putrefactive bacteria will spoil the batch.
However, a single large pickled cucumber can contain between 500 mg and 800 mg of sodium. In the UK, the NHS recommends that adults consume no more than 6 g of salt per day (approximately 2.4 g of sodium). Eating just two or three pickle spears can easily account for more than half of an individual's recommended daily salt allowance.
Excessive sodium intake carries several clinical risks:
- Cardiovascular Strain: High sodium intake draws water into the bloodstream, increasing blood volume and elevating blood pressure (hypertension), which raises the long-term risk of heart disease and stroke.
- Microbiome Impact: Paradoxically, while the probiotics in fermented pickles are beneficial, research indicates that chronic, excessively high dietary salt intake can actually suppress certain sensitive species of beneficial gut microbes, such as Lactobacillus, within the human bowel.
If you have diagnosed hypertension, chronic kidney disease, or cardiovascular concerns, you should speak with your GP before regularly adding high-sodium fermented foods to your daily routine.
Acidity, Reflux, and Digestive Discomfort
Pickles are inherently acidic, typically possessing a pH between 3.2 and 4.0. For individuals with sensitive upper gastrointestinal tracts, this level of acidity can irritate the lining of the stomach and oesophagus.
Common issues include:
- Gastro-Oesophageal Reflux (GORD): The acidity of pickling liquid can trigger heartburn, acid regurgitation, and retrosternal chest discomfort.
- Gastritis and Peptic Ulcers: Acidic foods can aggravate inflamed gastric mucosa, causing upper abdominal burning or nausea.
- Initial Bloating and Gas: When introducing live fermented foods into a diet that previously lacked them, some individuals experience a temporary increase in gas and abdominal distension as the gut microbiome adjusts to the influx of new bacterial strains.

| PICKLE CAUTION CHECKLIST |
| |
| Consider moderating or avoiding pickles if you have: |
| [ ] Diagnosed high blood pressure (hypertension) |
| [ ] Active gastro-oesophageal reflux (heartburn/acid reflux) |
| [ ] Diagnosed kidney conditions requiring sodium monitoring |
| [ ] Active gastric ulcers or acute gastritis |
| [ ] Noticeable symptom flare-ups following high-acid foods |
+-------------------------------------------------------------------+
Added Sugars and Food Colourings
When purchasing commercial pickles, you must also look closely at the ingredient panel for unnecessary additives. Many popular varieties, particularly "sweet gherkins", "bread and butter pickles", and commercial burger relishes, contain substantial quantities of added refined sugar or glucose-fructose syrup.
A 100 g portion of sweet pickles can contain up to 18 g of sugar. Diets high in refined sugars can promote dysbiosis by feeding less desirable microbial species in the lower bowel, directly countering any intended gut-health benefits.
Additionally, some mass-produced industrial brands add artificial colourings (such as tartrazine or Yellow 5) to give cucumbers an unnaturally vivid neon-yellow appearance. Choosing products made with clean, minimal ingredients—such as cucumbers, water, salt, garlic, dill, and natural spices like turmeric—is always the preferable choice.
Safety Warning: If you ever experience sudden, severe symptoms after eating—such as swelling of the lips, tongue, or throat, difficulty breathing, a widespread rash, dizziness, or collapse—seek immediate emergency medical help by calling 999 or attending your nearest A&E department.
How to Choose and Eat Gut-Friendly Pickles
If you wish to incorporate pickles into your diet for their potential digestive benefits, knowing how to navigate supermarket aisles and store your products correctly is essential.
Reading the Label: Spotting Live Cultures
To ensure you are buying pickles that contain living probiotics, keep the following practical shopping principles in mind:
- Check the Location in Store: Genuine, unpasteurised fermented pickles are biologically active and must be kept cool to slow ongoing fermentation. They are almost exclusively found in the chilled, refrigerated produce or delicatessen sections of the supermarket—not in the ambient, centre-aisle condiment shelves.
- Scrutinise the Ingredient List: An authentic fermented pickle should list very simple ingredients: vegetables, water, salt, and seasonings (like dill, mustard seeds, or peppercorns). If the label lists vinegar, acetic acid, or preservative agents like sodium benzoate or potassium sorbate, the product is not a traditionally fermented probiotic pickle.
- Look for Specific Phrasing: Seek out jars that explicitly state "naturally fermented", "unpasteurised", "raw", "contains live cultures", or "probiotic".
- Inspect the Liquid: Fermented brine is frequently slightly cloudy or milky, rather than crystal clear. When you open the jar, you may notice tiny bubbles rising to the surface—a natural sign that living bacteria are active and releasing carbon dioxide.
Making Fermented Pickles at Home Safely
Preparing your own lacto-fermented pickles at home is straightforward, cost-effective, and allows you to control the exact salt concentration. However, basic hygiene and food safety standards must be maintained to prevent contamination.
If you choose to ferment vegetables at home:
- Use Fresh, Unwaxed Produce: Select small, firm pickling cucumbers (such as Kirby cucumbers) rather than standard waxed salad cucumbers. Wash them thoroughly in cold water and slice off the blossom end, which contains natural enzymes that can soften the vegetable.
- Use Filtered Water: Tap water in many parts of the UK contains trace chlorine or chloramines, which are added to kill municipal bacteria. These disinfectants can inhibit the beneficial lactic acid bacteria you want to cultivate. Use boiled and cooled water, or filtered water.
- Maintain Proper Salt Ratios: A standard, safe brine typically requires a 2% to 3.5% salt concentration by weight. As a practical rule of thumb, dissolving approximately 20 g to 30 g of pure, non-iodised salt (such as coarse sea salt or kosher salt) into 1 litre of water provides a stable environment for lactic acid bacteria.
- Keep Vegetables Submerged: Ensure the cucumbers remain completely beneath the surface of the brine during fermentation using a clean fermentation weight. Produce exposed to oxygen at the top of the jar can develop surface mould (Kahm yeast or white fungal growth).
- Store Correctly: Allow the jar to ferment at cool room temperature (18°C to 22°C) away from direct sunlight for 4 to 10 days. Once the pickles have reached your preferred sourness and crunch, seal the jar tightly and move it to the refrigerator, where it will safely keep for several months.
How Much Should You Eat?
When it comes to probiotic foods, more is not necessarily better. Because fermented pickles are concentrated in both sodium and active organic acids, small, regular portions are ideal.
A single pickle spear or a few slices alongside your lunch or dinner is generally sufficient to provide dietary variety without overloading your system with excess sodium. Pairing your pickles with a balanced meal containing lean protein, healthy fats, and prebiotic-rich complex carbohydrates creates a well-rounded nutritional environment that supports steady, comfortable digestion.
The Blue Horizon Approach to Ongoing Digestive Symptoms
Adding fermented foods like pickles to your meals is a wonderful way to enjoy varied culinary traditions and gently support your dietary diversity. However, when everyday digestive issues—such as chronic bloating, sluggish digestion, fatigue, or abdominal discomfort—become regular obstacles, relying on dietary tweaks alone is rarely the answer.
At Blue Horizon, we advocate a structured, three-step journey to help you gain clear insight into your physical wellbeing without guesswork. Our practical guide to supporting the gut microbiome explains this broader approach in more detail.

+-------------------------------------------------------------------+
Step 1: Consult Your GP to Rule Out Underlying Conditions
Your very first port of call for any persistent, unexplained, or worsening digestive complaint must always be your NHS GP or qualified medical practitioner.
Your doctor can evaluate your medical history, perform a physical examination, and arrange essential baseline investigations. It is particularly important to undergo standard clinical rule-outs, including tests for coeliac disease, inflammatory markers, and routine blood counts to check for anaemia.
If your GP has run standard baseline tests and everything has come back marked as "normal", yet you still feel sub-optimal, run-down, or persistently uncomfortable, you are ready to move to the next stage of structured investigation.
Step 2: Track Your Diet, Lifestyle, and Symptoms
Before making dramatic dietary overhauls or investing in private investigations, spend two to three weeks keeping a clear, calm symptom diary. The human body operates as an integrated whole, and gut function is deeply intertwined with daily habits.
In your diary, track:
- Symptom Timing: Note exactly when bloating, discomfort, or energy slumps occur in relation to your meals.
- Lifestyle Factors: Record your nightly sleep duration, overall stress levels, and daily water intake.
- Digestive Rhythms: Note bowel movement frequency and consistency using the Bristol Stool Chart.
- Dietary Patterns: Log your general intake of dietary fibre, fermented foods, caffeine, and alcohol.
This structured log often reveals clear trends, demonstrating whether symptoms correlate with periods of poor sleep, heightened workplace stress, or specific meal timings, providing valuable objective context for both you and your healthcare team.
Step 3: Targeted Blood Testing to See the Bigger Picture
If you have completed basic checks with your GP and maintained a clear symptom log but still feel stuck, a comprehensive private blood test can provide a detailed biochemical snapshot to help identify underlying imbalances that influence gut motility, cellular energy, and overall vitality.
Digestive issues do not occur in isolation. For instance, low systemic iron stores (ferritin), vitamin B12 insufficiency, vitamin D deficiency, or elevated baseline inflammation can all impact energy levels and mucosal tissue health.
Similarly, the endocrine system plays a fundamental role in gut function. The thyroid gland acts as the body's metabolic master controller; an underactive thyroid can significantly slow intestinal motility, leading to chronic constipation and secondary bloating, while an overactive thyroid can cause hypermotility and loose stools.
Understanding Thyroid and Metabolic Testing Options
If your GP has evaluated basic markers but you want a more comprehensive picture of how your metabolic health and nutrient cofactors align, Blue Horizon offers a clear, tiered range of thyroid blood test profiles:
- Bronze Tier: A focused starting profile providing the foundational thyroid hormones—Thyroid Stimulating Hormone (TSH, the signal sent from the pituitary gland to instruct the thyroid), Free T4 (the primary circulating hormone), and Free T3 (the biologically active hormone that drives cellular metabolism). Crucially, all Blue Horizon tiers include our exclusive Blue Horizon Extras: Magnesium and Cortisol. Magnesium is an essential mineral cofactor involved in over 300 enzymatic processes, while cortisol reflects the body's physiological stress response—both of which can directly influence how energetic you feel and how your metabolism functions. You can review the Thyroid Premium Bronze profile for its included markers and collection options.
- Silver Tier: Builds upon the Bronze tier by adding Thyroid Peroxidase Antibodies (TPOAb) and Thyroglobulin Antibodies (TgAb). These markers evaluate whether autoimmune activity is targeting thyroid tissue, providing valuable context if standard hormone levels appear borderline. The Thyroid Premium Silver profile provides the specific details for this tier.
- Gold Tier: Combines all markers from the Silver tier with a broader health and nutritional screen. It measures Ferritin (stored iron), Folate, Active Vitamin B12, Vitamin D (25-OH), and C-Reactive Protein (CRP), a sensitive marker of low-grade systemic inflammation. This tier offers a comprehensive snapshot for those experiencing unexplained fatigue alongside digestive irregularities. See the Thyroid Premium Gold profile for its biomarker breakdown.
- Platinum Tier: Our most advanced thyroid and metabolic profile. It incorporates everything in the Gold tier and adds Reverse T3 (an inactive form of T3 that can rise during physiological stress), HbA1c (a long-term measure of average blood sugar control), and an extended iron panel including Iron, Transferrin Saturation, Total Iron-Binding Capacity (TIBC), and Unsaturated Iron-Binding Capacity (UIBC). The Thyroid Premium Platinum profile contains the most extensive range of markers described here.
Sample Collection and Clinical Review
To ensure accurate, reliable results, sample collection options are designed around patient convenience:
- Bronze, Silver, and Gold Profiles: Can be collected from the comfort of your home using a simple fingerprick (microtainer) kit, via a convenient Tasso home collection device, or through a venous blood draw arranged at a partner clinic or via a visiting nurse.
- Platinum Profile: Due to the comprehensive nature of the extended iron and metabolic markers, the Platinum tier requires a professional venous blood draw, arranged via a clinic appointment or nurse home visit.
- Timing: For all thyroid-related panels, we generally recommend taking your sample at 9:00 am, as hormone levels naturally fluctuate throughout the day, and morning testing ensures consistency.
You can view current pricing and detailed biomarker breakdowns on the thyroid blood tests collection page.
It is important to remember that private blood test results are not a self-diagnosis, nor do they replace professional medical care. Instead, our doctor-reported results provide an objective, comprehensive health summary designed to facilitate an informed, productive conversation with your GP or specialist. If you are currently prescribed thyroid or metabolic medication, any adjustments to your dosage must always be managed directly under the supervision of your GP or endocrinologist.
Conclusion
So, are pickles good for gut health? When they are traditionally lacto-fermented in a simple saltwater brine, raw and unpasteurised pickles can indeed be a tasty, supportive source of living probiotic bacteria, beneficial organic acids, and bioavailable micronutrients. They can play a valuable, flavourful role within a diverse diet rich in whole grains, legumes, fruits, and vegetables.
However, standard shelf-stable pickles preserved in vinegar, while crisp and enjoyable as a condiment, do not provide live probiotic benefits. Furthermore, because all pickles are inherently high in sodium and acid, they should be eaten in moderation and approached with care by anyone managing high blood pressure, acid reflux, or sensitive gastric conditions.
If you are navigating persistent digestive symptoms, fatigue, or general wellness challenges, remember that sustainable health is built step by step:
- Consult your GP first to evaluate your symptoms and rule out underlying clinical conditions.
- Use structured lifestyle and symptom tracking to understand your body's unique patterns and triggers.
- Consider targeted blood testing when you need a clear, objective snapshot of your internal biochemistry to guide targeted lifestyle discussions with your doctor.
By taking a calm, evidence-informed approach to your diet and your health, you can nourish your body with confidence and clarity.
FAQ
Are all pickles from the supermarket good for gut health?
No. The vast majority of pickles found on ambient supermarket shelves in the UK are preserved in vinegar and heat-pasteurised for long-term shelf stability. This pasteurisation process sterilises the jar and destroys all living bacteria. For gut-health probiotic benefits, you must choose naturally fermented, unpasteurised pickles that have been cured in a saltwater brine without added vinegar, typically found in the refrigerated section of the store.
Can eating pickles help relieve severe bloating or chronic IBS?
While the live cultures in fermented pickles can gently support microbial diversity, they are not a medical treatment for chronic digestive disorders like irritable bowel syndrome (IBS) or severe bloating. In some instances, the high acidity or rapid introduction of active microbes can temporarily increase gas and digestive sensitivity. Anyone experiencing ongoing digestive discomfort should consult their GP for proper clinical evaluation.
Is it safe to drink the juice from a pickle jar?
Pickle juice contains water, sodium, and organic acids. Some individuals and athletes use small amounts of pickle juice to help replace electrolytes lost through heavy sweating or to ease muscle cramps. However, pickle brine is exceptionally high in salt and acid. Drinking large amounts can place undue stress on your cardiovascular system, raise blood pressure, and irritate the stomach lining. It should only be consumed in minimal amounts, if at all, and avoided by those on low-sodium diets.
What is the healthiest way to include pickles in a balanced diet?
The healthiest approach is to consume small portions of raw, naturally fermented pickles—such as a single spear or a few slices—alongside a balanced meal containing lean protein, healthy fats, and prebiotic fibre (such as whole grains or leafy greens). This provides the probiotic benefits and satisfying crunch of fermented vegetables while keeping total daily sodium intake well within recommended NHS guidelines.
