The bigger concern is the frequent consumption of refined and highly processed carbohydrate-rich foods, especially when they are high in calories and low in fiber.
Examples include:
- White bread
- Many commercially produced pastries
- Sugary breakfast cereals
- Cookies
- Cakes
- Donuts
- Sweet crackers
- Some highly processed snack foods
- Large portions of refined pasta or rice combined with calorie-dense sauces
Refined grains have generally had some of their natural structure and fiber removed. This can make them easier to eat in large quantities.
Fiber is particularly important because it can increase fullness, support digestive health, and help regulate blood glucose responses.
Choose whole-food carbohydrate sources more often
Better options can include:
- Oats
- Barley
- Brown rice
- Whole-grain bread
- Whole-grain pasta
- Quinoa
- Beans
- Lentils
- Chickpeas
- Potatoes and sweet potatoes
- Fruits
- Vegetables
The goal is not to fear carbohydrates. The goal is to choose higher-fiber, minimally processed carbohydrate sources more often and pay attention to portion sizes.
4. Ultra-Processed Foods
Ultra-processed foods are products that have been substantially formulated or modified during industrial processing and often contain combinations of refined ingredients, added sugars, fats, sodium, flavorings, and other additives.
Examples can include:
- Packaged snack foods
- Some fast-food meals
- Processed desserts
- Certain packaged breakfast products
- Highly processed frozen meals
- Some sweetened snack bars
- Commercial baked goods
- Processed chips and crackers
Not every processed food is unhealthy. Frozen vegetables, canned beans, plain yogurt, pasteurized milk, and many other processed foods can be highly nutritious.
The concern is particularly with ultra-processed foods that are easy to overconsume and high in calories while being relatively low in fiber and micronutrients.
These foods can make it easier to consume more energy than the body needs.
A simple strategy
Instead of trying to identify every food as “good” or “bad,” ask:
What is the food mostly made of, and how easy is it for me to overeat it?
A meal built around vegetables, legumes, whole grains, lean protein, nuts, seeds, and minimally processed foods will generally be more filling and nutrient-dense than a meal dominated by refined starches, added sugars, and highly processed snacks.
5. Processed Meats and Frequent High-Calorie Meat-Based Foods
Processed meats include products such as certain sausages, hot dogs, bacon, salami, and other meats that have been preserved or transformed through methods such as curing, smoking, fermentation, or the addition of preservatives.
These foods can be high in sodium and saturated fat, depending on the product. Regularly eating large amounts of processed meat is associated with several long-term health concerns.
