It feels like a warm, sensible choice: quick to heat, packed with vegetables, and apparently ticking the “five-a-day” box. Yet French doctor and media health expert Jimmy Mohamed says most people are missing one crucial detail on the label that separates a genuinely good vegetable soup from a clever marketing trick.
Why that carton of soup isn’t always what it seems
Homemade soup made with fresh, seasonal produce still sets the standard for nutrition and flavour. Yet modern life does not always allow time to peel, chop and simmer for an hour. Ready-made soups in cartons or bottles have become a fallback: you open, pour, heat, and eat. The ritual feels wholesome, especially when the front of the pack shows generous slices of leeks, carrots and cabbage.
The issue starts when you stop at the front of the packaging. Health claims, rustic photos and words like “traditional” or “country-style” can create the illusion of a vegetable-rich meal. The reality, according to Jimmy Mohamed, lies on the back of the carton in the ingredients list and nutrition table.
For a supermarket vegetable soup to be genuinely good, Mohamed says it should contain around 50–60% vegetables.
That single number, often tucked away in fine print, changes everything.
The 50–60% rule: what Jimmy Mohamed looks for
Speaking on RTL in France, Jimmy Mohamed explained that the first thing he checks on a soup carton is the actual percentage of vegetables. Many shoppers assume “vegetable soup” means mostly vegetables. In reality, some products fall far below that threshold.
Mohamed’s basic rule:
- Vegetables should make up between 50 and 60% of the soup.
- Starchy ingredients should stay in the minority, around 10–15%.
- Salt, additives and artificial flavourings should be limited.
When the vegetable percentage drops, manufacturers often compensate with other ingredients that fill the carton cheaply and give a thick, smooth texture.
The potato problem: cheap filler vs real vegetables
One of the main culprits is the humble potato. Mohamed points out that food companies frequently load soups with potatoes because they are inexpensive, easy to store and provide body to the product. On a label, that can look like this: “Water, potatoes, carrots, leeks…”

When potato appears first in the ingredients list, your “vegetable soup” is closer to a starch-based soup than a bowl of greens.
Nutrition-wise, that matters. Potatoes belong to the starchy foods group, like rice or pasta, not to the vegetable group used in public health guidelines. So even if the front of the packaging shows a mountain of broccoli or spinach, the bulk of the product might be something else entirely.
Why you shouldn’t completely avoid starches in soup
That does not mean Mohamed wants you to ban potatoes from your bowl. On the contrary, he notes that a soup with absolutely no starchy ingredients can leave you hungry too quickly. Starches such as potatoes, lentils, chickpeas or sweet potatoes help you feel full and keep your energy up between meals.
The key is balance: enough starch for satiety, but not so much that vegetables become secondary.
Mohamed suggests that starchy foods should represent around 10–15% of the total weight of the soup. That level supports fullness while leaving most of the space to non-starchy vegetables, which bring vitamins, minerals, fibre and a wide variety of protective plant compounds.
How to read the label in 10 seconds
The supermarket aisle is not the place for a long nutrition lesson, so Mohamed’s advice is built for speed. The idea is to flip the carton, check a few key elements, and decide on the spot whether to keep it or put it back.
Here is a quick mental checklist you can use:
- Ingredients order: if potato or another starch appears first, that soup is not primarily about vegetables.
- Vegetable percentage: look for 50–60% vegetables overall, not just one or two types.
- Starch percentage: aim for 10–15% potatoes, legumes or other starchy additions, not more.
- Salt: prefer soups with moderate sodium per serving (roughly under 1g of salt per 250ml is a useful guide for adults).
- Additives: shorter ingredient lists, with familiar terms, tend to be closer to what you would use in your own kitchen.
Beyond vegetables: salt, fibre and additives
Once you have checked the vegetable content, the nutrition table offers more clues. Soups vary heavily in salt, fibre and added extras such as thickeners and flavour enhancers.
| Element to check | What to look for | Why it matters |
|---|---|---|
| Salt (sodium) | Lower side compared with similar soups | High salt intake is linked with raised blood pressure and heart risk. |
| Fibre | Several grams per portion | Fibre supports digestion, satiety and blood sugar balance. |
| Additives & flavourings | Limited, simple ingredients | Many people prefer to reduce exposure to ultra-processed elements. |
Industrial soups can contain stabilisers, modified starches, artificial aromas or colourants. Not all additives are dangerous, but they rarely add nutritional value. A list mainly made of vegetables, water, a plant oil and spices is closer to homemade cooking than a product packed with codes and chemical-sounding names.
How this plays out in a real shopping trip
Imagine you are standing in front of three different cartons of “vegetable soup”:
- Soup A lists “water, potatoes, carrots, leeks” and shows 25% vegetables, 20% potato.
- Soup B lists “water, carrots, leeks, onions, potatoes” with 55% vegetables and 10% potato.
- Soup C adds cream, cheese, croutons and several E-number additives.
Using Mohamed’s rule, Soup B is the clear winner. It respects the 50–60% vegetable target; potatoes appear, but not in first position and at a limited share. Soup A leans too heavily on cheap starch, while Soup C starts to look more like an indulgent dish than an everyday, vegetable-focused choice.
The best supermarket soup is not the one with the prettiest picture, but the one whose first ingredient is actually vegetables.
What “five-a-day” really means for your soup
Marketing often suggests a bowl of soup equals one or more portions of vegetables. Public health guidelines usually define one portion as roughly 80g of vegetables or fruit. A 250ml serving of a soup containing 50–60% vegetables will therefore often contribute a meaningful amount toward that target.
Yet a soup heavy in potatoes or cream, even if labelled as “vegetable”, will contribute less to your fibre and micronutrient intake than a soup where the bulk is made up of varied plants such as carrots, leeks, spinach, peas or courgettes.
Turning a basic carton into a genuinely nutritious meal
Even a decent industrial soup can be upgraded at home in a couple of minutes. This is useful when the only option available in your cupboard is a fairly average product, not perfectly aligned with Mohamed’s ideal criteria.
You can enhance it by:
- Adding a handful of frozen or fresh vegetables while reheating (peas, spinach, kale, diced carrots).
- Stirring in cooked lentils or chickpeas to boost protein and fibre.
- Finishing with a drizzle of olive oil or a spoonful of plain yogurt for extra creaminess instead of relying on industrial cream.
- Sprinkling herbs, garlic, pepper or paprika instead of extra salt for flavour.
These small changes turn a convenient base into a more complete, satisfying meal and may reduce the temptation to rely on bread or cheese to feel full.
Why this small label check matters in daily life
On its own, one bowl of soup will not transform your health. Yet ready-made soups often appear several times a week during colder months. If each of those bowls is largely starch disguised as vegetables, you might be regularly missing out on the benefits associated with a varied, plant-rich diet.
Over time, choosing soups that follow Mohamed’s 50–60% vegetable rule can help raise overall fibre intake, support weight management, and improve blood sugar control, especially if you are prone to energy dips after meals. For people with high blood pressure or heart concerns, regularly opting for products with moderate salt can also make a measurable difference when combined with other lifestyle steps.
In the end, the gesture that changes everything takes only a few seconds: turn the carton around, read past the marketing, and check whether your “vegetable soup” is, in fact, made mostly of vegetables.
