10 Lebensmittel, die wir für gesund halten, die es aber nicht sind

Often presented as healthy, fiber-rich snacks, industrial cereal bars are actually little bombs of hidden sugar.

Behind their “natural” image, they often contain glucose syrup, added sugars, hydrogenated fats, and a long list of artificial flavors.

Most of their ingredients come from ultra-processed foods that have been largely broken down and recomposed. The result is a product that is closer to a candy than a healthy snack.

For a truly nutritious alternative, opt for a raw snack: a few dates, almonds, and oat flakes make a simple, satisfying, and authentic mix.

Contrary to popular belief, oat milk is not always the healthiest option. Among plant-based milks, it is one of the sweetest, as oats naturally convert to glucose during production.

The result is a high glycemic index that causes blood sugar levels to rise faster than you might think. Many commercial versions also contain thickeners or added sugars.

For a more stable and less sweet alternative, try unsweetened soy milk or almond milk, which have a simpler composition and a much gentler glycemic impact.

A glass of fruit juice seems harmless, but it is far from being as healthy as we think. Once pressed, fruit loses almost all of its fiber, which slows down the absorption of sugar.

As a result, juice contains a high concentration of fructose and causes a spike in blood sugar levels comparable to that of a regular soda. We think we’re making a healthy choice, when in fact we’re mainly drinking liquid sugar.

The ideal solution is to eat the whole fruit, which satisfies your hunger and stabilizes your blood sugar levels. A fresh and light alternative is a cold infusion or unsweetened matcha green tea, which is much more balanced.

“Light” products often give the illusion of being healthier, but they are far from being a good option. To compensate for the lack of fat, manufacturers add thickeners, artificial sweeteners, and various additives that provide neither satiety nor real nutrients.

The result: you get hungry faster and tend to consume more. Conversely, plain whole yogurt, rich in good fats, is more filling and stabilizes blood sugar levels.

Topped with chia seeds and fresh fruit, it becomes a simple, nutritious snack that is truly beneficial to your health.

Despite their apparent lightness, rice cakes are far from being an ideal choice. Their very high glycemic index causes an almost immediate spike in blood sugar, followed by a rapid drop that reawakens hunger.

In addition to being low in fiber, protein, and nutrients, they are absorbed in the blink of an eye, which means they are not very filling. We think we are snacking “lightly,” but we are actually fueling our cravings.

To satisfy a small appetite in a lasting way, a handful of unsalted nuts, almonds, walnuts, or hazelnuts is a much more nutritious and satisfying option.

Smoothies look healthy, but they often contain much more sugar than you might think. By blending several fruits, sometimes with coconut milk or other sweet liquids, you end up with a drink that is very high in fructose and lacking in fiber, which slows down sugar absorption.

The result is a sharp spike in blood sugar, which puts a lot of strain on the liver and leaves you feeling hungry again shortly afterwards.

To really benefit from the nutrients, it is better to enjoy a whole fruit or a homemade fruit salad, which are much more balanced and filling.

Most whole grain breads sold in supermarkets are whole grain in name only. They are often made from refined white flour simply enriched with bran, resulting in a product that is low in fiber and ultimately very similar to a traditional baguette.

Sugar, flavorings, preservatives, added gluten, and oil are also frequently added to improve the texture. The result is a highly processed bread that is far from the healthy image attributed to it.

For real wholemeal bread, it is better to make it yourself or buy it from an organic bakery, where the flour is truly wholemeal.

Margarine is often presented as a “lighter” alternative to butter, but it is actually a highly processed product.

It is made by emulsifying water and vegetable oils (rapeseed, copra, palm) with additives, salt, plant sterols, and synthetic vitamins to improve texture and shelf life. Despite its healthy image, its composition is very far from that of a natural food. For spreading, it is better to opt for nut butter or a small amount of butter. When cooking, choose simple vegetable oils such as olive, walnut, or sunflower, which are much more authentic.

Cornstarch is often used to lighten or thicken recipes, but it is far from being a harmless ingredient.

Very rich in starch and lacking in gluten, protein, and fiber, it has a particularly high glycemic index.

As a result, it causes a rapid rise in blood sugar and strongly stimulates insulin secretion, which is not ideal for satiety or metabolic health.

For more balanced and gluten-free alternatives, choose legume, chestnut, or buckwheat flours, which are significantly more nutritious and filling.

With the rise of vegetarianism, store shelves have filled up with “ready-to-eat” options. However, behind their healthy image, many industrial vegetarian dishes contain preservatives, additives, texturizers, and sometimes even questionable flavorings designed to mimic the texture or taste of meat.

The result is a highly processed product that is far removed from the natural diet that people often seek when adopting a vegetarian lifestyle.

For a truly healthy meal, it’s better to cook for yourself using raw ingredients such as plain organic tofu, soy protein, almonds, and fresh vegetables, and season them to your liking.
