There are misleading claims about what's called 'healthy' by the manufacturers. The Journal of Nutrition Education and Behavior explains the vague in such marketing that often leads to misconception. Saturated fat, sugary juice, and a lot of kid's products are said to be packaged as healthy.

Nielsen survey indicated 59% of consumers cannot understand the nutrition labels that manufacturers put on the front of the box. The study reported that consumers are skeptical about the nutritional claims. However, 33% of them said the calorie count on the label is trustworthy and sometimes accurate.

So, what are those so-called healthy foods?

All-Natural

All natural may be ideal to describe no artificial flavoring, color addition or any synthetic matter. However, it could be sodium-injected, corn-syrup added, and many other types of healthy forms which aren't healthy at all.

Fruit-Juice Concentrate

A good phrase to explain this, would be 'sugared drink'. Pandora's Lunchbox author, Melanie Warner, explained that human's body isn't able to distinguish between high fructose syrup or fruit juice concentrate. The process takes a lot of steps including sweetener and essence.

Sugar Free

Sugar free is not equal to calorie free. It could contain more carbs and calories although it has less sugar per serving. Always compare the label with the regular product and see if the amount is any better. Names such as xylitol, mannitol, sorbitol are just another words for sugar, too.

Multigrain

100% whole wheat is different from multigrain. Multigrain means that the bread is made from various grains - which could be a refined and stripped healthy product. The dark colored bread may also be added with caramel color - which is similarly unhealthy to the refined bread. Nutritionist  Katherine Tallmadge suggests buying breads labeled with 'whole grain'.

Serving size

Serving size often comes with half a cup but a person could eat 3 cups of ice cream and forget to multiply the calories by the number of serving size. People tend to imply serving size as the portion size - which could possibly lead to consuming larger amount of calories when you're on diet.
