Several nutritionists are advising consumers to rethink common grocery staples, revealing surprising "healthy" foods they avoid. Experts suggest that many products marketed as beneficial are often high in sugar, unhealthy fats, or unnecessary additives, while their less processed alternatives offer superior nutritional value.

Nutritionist Rachel Butcher, head of nutrition at Third Space, states that healthy eating does not need to be complicated, but the abundance of information and wellness products can be overwhelming. She and other leading nutrition experts have identified several items that rarely make it into their shopping trolleys and suggest better alternatives.

Beans

While beans are praised for their fiber content, crucial for bowel cancer prevention, and as a source of protein for vegetarians and vegans, experts advise against dried beans. Clementine Vaughan, a registered dietitian and founder of Third Sister, notes that canned beans are nutritionally equivalent to dried beans but offer significant convenience. "Pre-cooked beans in a can are just as good nutritionally and are very convenient," Vaughan said. "If they make it easier for people to eat beans, then it's a win in my opinion."

Yogurts and Cereals

Plain natural or Greek yogurt are recommended by Butcher over flavored varieties, which can contain substantial amounts of sugar—sometimes equivalent to a chocolate biscuit. She also cautions against products labeled "high protein" or "for gut health," calling them marketing ploys. Butcher suggests adding frozen berries to plain yogurt for sweetness and nutritional benefits.

Similarly, supermarket granolas are often criticized for being high in oil and sugar, with easily underestimated portion sizes. Butcher points out that a bowl of granola can contain more sugar and calories than sugary breakfast cereals like Frosties or Cocoa Pops.

Prepared Produce and Dressings

Nutritionist Xuxa Milrose, from OMNI wellness, advises against pre-prepared fruits and vegetables, such as pre-cut apples or melon. While convenient, these items come at a premium and may lack nutrients that can degrade after cutting. Milrose recommends buying whole produce and preparing it at home, or opting for frozen chopped vegetables, which are typically frozen soon after harvest to preserve nutrients.

Furthermore, experts warn of food poisoning risks associated with pre-cut produce due to potential bacterial contamination during handling. Milrose also advises caution with ready-made salad dressings, many of which contain emulsifiers, thickeners, and high levels of saturated fat and sugar. These additives can disrupt the gut microbiome and contribute to inflammation. A simple homemade dressing of olive oil, lemon juice or vinegar, mustard, and seasoning is recommended.

While chewing gum is often used to curb appetite, it contains potentially harmful additives

Protein Bars and Chewing Gum

Protein bars, especially those marketed for weight loss, are frequently identified as items to avoid. Butcher notes that many are nutritionally similar to chocolate bars but are consumed in greater quantities by those aiming to increase protein intake. She advocates for obtaining protein from sources like meat, fish, poultry, legumes, Greek yogurt, and lentils, allowing for the occasional enjoyment of a chocolate bar.

Dietitian Clementine Vaughan also advises against sugar-free chewing gum, which often contains xylitol. Xylitol can be a gut irritant, potentially causing bloating and wind in some individuals, and in larger amounts, can have a laxative effect. Some studies have also linked high intake of sweeteners like xylitol to an increased risk of blood clots, heart attacks, and strokes.

Nutritionists split food into three groups based on the amount of processing they have gone through. Minimally processed foods, like apples, are usually exactly how they appear in nature. Processed foods, like apple sauce, have gone through at least one level of processing that has changed their original form. In contrast, ultra-processed foods like apple jelly babies, have gone through multiple levels of processing and are usually full of extra fats, colours and preservatives
