There is a lot of conflicting information when it comes to nutrition. It seems that every day there is a new headline that’s at odds with everything we thought we knew. Despite emerging science, many nutrition myths are still prevalent. Here’s the truth about some common nutrition myths.
Myth: Egg yolks are high in cholesterol and should therefore be avoided
Fact: For decades, we were told not to eat eggs too often (and only the whites) if we wanted to be healthier and avoid elevated cholesterol. The latest evidence, however, shows that advice was scrambled. While egg whites are an excellent source of protein, the egg yolks contain most of the major nutrients including iron, folate and vitamins that support eye and brain health. The dietary cholesterol in eggs that was demonized for decades is now largely recognized by the medical community as having little effect on blood cholesterol. Overall, eggs contain a host of valuable nutrients, and focusing on the cholesterol content of eggs as a contributor to disease is not only counter-productive but false. Maintaining a balanced eating pattern with plenty of plant-based proteins and fats with the occasional animal product is the key to keeping those blood lipids at an optimal level.
Myth: Coffee is bad for you
Fact: The majority of studies on coffee have actually shown it provides protective effects against disease. Coffee is loaded with antioxidants, and has also been shown to help reduce the risk of developing diabetes in regular consumers. It’s likely the bad reputation comes from cream and sugar many people add to their drink. Adding sweetener greatly decreases this protective effect. To reap the most benefits, limit the amount of cream, milk, sugar, or artificial flavorings you add to your coffee.
Myth: You can eat as much “healthy” food as you like
Fact: The key to a healthy lifestyle is eating a variety of foods from all the main food groups. What this means is that just because the media touts avocados and kale as healthy “superfoods,” it doesn’t mean more is better; even healthy foods still need to be eaten in moderation. Ever hear of the saying, “too much of a good thing?” It applies to so-called healthy foods too. The body needs a certain amount of nutrients to function, and any excess is either stored as fat or eliminated. Plus, when you eat from only a small selection of foods, you miss opportunities to obtain vital nutrients from other sources. No one food contains all the macro- and micronutrients we need. That’s why it’s so important to view articles that promise things such as “eat as much of these foods as you want and never gain weight” with a critical eye. These headlines are designed to grab your attention using the allure of being able to eat all day long and never gain weight. To maintain health, eat a variety of foods, from all the food groups, in portions that are satisfying but don’t leave you feeling overly full all the time.
Myth: Gluten Free is healthier…and other labeling misconceptions
Fact: The term “health halo” is given to foods with a reputation for being better for you. They may have a special title or brand that is associated with being more nutritious, but this is not always the case. For instance, foods like smoothies, granola, organic snacks, protein shakes or foods labeled “organic” or “gluten free” are often thought of as being better options. The fact of the matter is that this is simply marketing and tailoring to consumer demand. Gluten is a protein found in wheat that has received a lot of attention recently. People with celiac disease or gluten sensitivity need to avoid gluten, but there is no need for the average person to eliminate gluten from their diet. As for organic foods, if you have the resources to purchase the “dirty dozen” (produce known to have high levels of pesticides) organic, wonderful. If not, you will not be losing out on any of the health-giving vitamins and minerals found in fresh produce. Learn more about the “dirty dozen” and “clean fifteen” and make an informed decision about which foods you will purchase organic. Overall, beware of falling for labeling traps and use your best judgement!
