Food labels can be useful tools, but they can also be confusing. Packaging may highlight claims such as “high protein,” “low fat,” “natural” or “no added sugar,” while the full nutrition facts and ingredient list tell a more complete story.
You do not need to fear every unfamiliar ingredient or choose only foods with very short ingredient lists. A better approach is to understand what the label is showing you, look at the overall nutritional value of the food, and decide whether it fits your needs.
Start With the Serving Size
The serving size tells you what amount of food the nutrition information refers to. If you eat twice the listed serving, you will also get roughly twice the calories, protein, carbohydrate, fat and sodium shown on the label.
Serving sizes are not rules about how much you are “allowed” to eat. They are simply a reference point that helps you compare foods and understand the information on the package.
Look at the Nutrition Facts
A few things can be especially useful to notice:
- protein
- fiber
- sodium
- saturated fat
- added sugars, when listed
- vitamins and minerals
- total calories, if that information is relevant to your goals
You do not need to choose foods based on only one number. A product can be high in sodium but also high in protein and useful in a particular meal, or higher in calories but still nutrient-dense and satisfying.
Context matters.
How to Read the Ingredient List
Ingredients are generally listed in descending order by weight, so the ingredients near the beginning are present in the greatest amounts.
Instead of assuming that fewer ingredients always means a healthier food, ask whether the ingredient list makes sense for the product. A loaf of bread, yogurt, soup or protein bar may naturally contain several ingredients and still be a perfectly reasonable choice.
The goal is not to avoid every additive. It is to understand what you are buying.
What About Additives and Preservatives?
The original version of this article listed many additives as if they were automatically dangerous. I would remove that approach.
Food additives approved for use in Canada are assessed for safety within permitted amounts. That does not mean every highly processed food should make up most of your diet, but it also does not mean ingredients such as colours, preservatives, natural flavours or artificial sweeteners are automatically harmful.
A more practical question is: How often am I eating this food, and what does my overall eating pattern look like?
If most of your diet includes a variety of foods such as vegetables, fruit, whole grains, legumes, protein-rich foods, nuts, seeds and other nutrient-dense options, there is room for packaged foods too.
Trans Fat
Trans fats are worth paying attention to because higher intake is associated with cardiovascular risk. In Canada, partially hydrogenated oils were banned as an ingredient in foods, which has significantly reduced industrial trans fat in the food supply.
You can still check labels, but this is not the same issue it was years ago.
Added Sugar
Food companies may use different forms of sugar, including cane sugar, glucose, dextrose, syrups, honey and others.
Rather than trying to identify and eliminate every type of sugar, look at how the food fits into the bigger picture. A product with some added sugar can still fit into a balanced diet, while a diet made up mostly of sweetened drinks, desserts and low-fiber snack foods may provide less overall nutrition.
Sodium
Sodium is another useful item to notice, especially if you eat many packaged or restaurant foods. You do not need to avoid salt completely, but being aware of sodium can help you compare similar products and make choices that fit your health needs.
Artificial Sweeteners
Artificial and non-sugar sweeteners are not automatically harmful. Some people find them useful for reducing added sugar, while others prefer not to use them because they dislike the taste or notice digestive discomfort.
You do not need to treat them as either “good” or “bad.” They are simply one option.
Portion Size Without Obsession
Portion awareness can be helpful, but it does not need to become rigid.
Simple visual references can be useful when you do not want to weigh or measure everything:
- 1 cup is roughly the size of a fist
- ½ cup is roughly a cupped hand
- about 3 ounces of meat or fish is roughly the size of a palm
- 1 tablespoon is roughly the size of a thumb
- 1 teaspoon is roughly the tip of a thumb
These are approximate guides, not exact rules.
A Simple Way to Build a Balanced Plate
Instead of focusing only on restriction, try building meals around a few basics:
- a source of protein
- vegetables or fruit
- a source of carbohydrate
- some healthy fat
- enough food to leave you satisfied
That could look like salmon, potatoes and vegetables; tofu with rice and stir-fried vegetables; yogurt with fruit and oats; or beans, avocado and whole-grain tortillas.
Focus on the Overall Pattern
Food labels can help you compare products, understand portions and notice nutrients, but no single ingredient determines whether your diet is healthy.
The bigger picture matters more: variety, enough protein and fiber, regular meals, fruits and vegetables, enjoyable foods, and habits you can maintain.

You may also find Food Journaling vs. Calorie Counting useful if you want to become more aware of your eating patterns without getting overly focused on numbers.
