To help Americans make healthier food choices, we have MyPlate: a simple graphic that explains how much of each food group to eat at every meal. The illustration, which replaced the MyPyramid graphic in 2011, is simple, easy to understand and endlessly customizable.
What's fascinating about these illustrations is that despite the fact that they reflect unique historical and culinary traditions, they're actually more alike than not, says Christopher Gardner, a nutrition scientist at Stanford Prevention Research Center.
"They are more similar than different in terms of which food groups fall into which proportions," Gardner wrote in an e-mail to HuffPost. "Grains, veggies and fruits always fall into the largest categories."
As you scroll through the different guides, ask yourself: Am I eating enough plant-based foods? How often am I really eating foods high in sugar, salt and fat (junk foods that are not even pictured in most food guideline illustrations)? And am I overlooking any foods from my culinary heritage that could fit into a pattern of healthy eating?
The U.S. "MyPlate" guide to healthy eating uses a plate to display, roughly, how much of each kind of food you should eat at every meal. Fruits and vegetables should be varied and take up half the plate. The grains section should be at least 50 percent whole grains, the dairy should be low-fat milk or yogurt and the protein should also be varied.
Other MyPlate principles include eating the right number of calories for your age and height, avoiding saturated fat, sodium and added sugars, creating a supportive community that makes healthy eating easier.
The goal of these nutritional guidelines is to avoid obesity and chronic diseases.
Japan's food guide is modeled after the spinning top, a popular toy in the country. The guide is dish-based and features traditional Japanese cuisines like noodles, rice, mushroom and seaweed.
Experts note that the guide is high in carbohydrates like grains and vegetables, and low in fat -- an interesting detail to note, considering the many diet trends in the U.S. that call for lowering grains and increasing dietary fat.
Brazil does not have an illustrated food guide. Rather, it has a list of ten principles for healthy eating, as well as a few photo examples of real meals that align to these principles.
These principles include advice to eat mostly natural, minimally processed foods, eat with company and be wary of food advertisements. They have been praised by experts for their holistic and progressive approach to healthy eating.
The photo above depicts four different dishes for dinner. They mostly include both rice and beans, which reflects the nation's culinary traditions. Vegetables make an appearance in all meals. Red meat is just one option for protein. Others include chicken, eggs and fish.
The Chinese Dietary Guidelines are illustrated with a pagoda. A person running toward the pagoda represents the importance of exercise. The base of the pagoda is made up of of grains like rice, bread and noodles. These starches, along with fruits and vegetables on the next level, should be the majority of any meal, the guidelines state.
Proteins like fish, meat, poultry and eggs should be eaten often but in small amounts, and then dairy and beans are on the top level. Fat, oil, and salt, which should be eaten sparingly, makes up the roof of the structure.
The U.K.'s "Eatwell Guide" states that both grains and fruits and vegetables should each make up over one-third of a person's total diet. The next largest food group is protein, which contains lentils and beans as well as the usual suspects fish, meat and poultry.
Dairy or dairy alternative foods should be low-fat, and oils are an important part of the diet but should be eaten in small amounts.
Food that is high in sugar, salt and fat are outside the circle because we don't need them to live and they should be eaten sparingly.
South Africa's food guidelines were created to address two different populations: people who are undernourished and who need to eat more nutritious foods, and people who are struggling with being overweight and obese. They state that starchy foods should be a part of most meals and that fruits and vegetables should be eaten every day.
People should also drink milk, yogurt or maas (an African fermented milk) daily, as well as clean, safe water. Meat, fish and eggs can also be eaten daily, while things like beans, lentils and soy can be eaten regularly.
Their guidelines also address the dangers of eating tasty but nutritionally deficient food (foods high in sugar, salt and fat), especially for people who come from an undernourished background. From the report:
"It should also be remembered that when previously disadvantaged people who were hungry or food insecure at any time of their life are suddenly confronted with a wide variety of affordable and palatable food, their choices are not necessarily governed by what is healthy."
Qatar recommends three to five servings of vegetables and two to four servings of fruits every day. For the other four food groups (cereals and starchy vegetables, legumes, dairy and dairy alternatives, and fish and meat), they recommend eating some from each group every day, but give no suggested serving size. Foods high in sugar, salt and fat are not depicted in the shell illustration.
The guidelines contain a special section on weight loss that emphasize the importance of sleep, exercise and social support. From the report:
"Do not obsess about weight. Stay positive, and focus on eating well and being active. If you have children that are overweight, this is even more important."
In addition to their rainbow-shaped food guide, Canada has also created a circular guide to address the traditional diets of the First Nations, Inuit and Metis people.
The guideline has serving size recommendations for traditional foods like whale and seal oil, bannock, seaweed and wild game.
