From a psychological and cultural perspective, a healthier diet may be difficult to achieve for people with poor eating habits. This may be due to tastes acquired in childhood and preferences for sugary, salty and/or fatty foods. In the UK, the chief medical officer of the government recommended in December 2018 that sugar and salt be taxed to discourage consumption.
For people who are healthy, a healthy diet is not complicated and contains mostly fruits, vegetables, and whole grains, and includes little to no processed food and sweetened beverages. The requirements for a healthy diet can be met from a variety of plant-based and animal-based foods, although a non-animal source of vitamin B12 is needed for those following a vegan diet. Various nutrition guides are published by medical and governmental institutions to educate individuals on what they should be eating to be healthy. Nutrition facts labels are also mandatory in some countries to allow consumers to choose between foods based on the components relevant to health.
Losing weight isn't all about exercise – what you eat matters too. But nobody wants to eat diet food that makes them feel like they're going to gnaw their arm off before dinner. That's why registered dietitians say it's important to up your intake of veggies, grains, nuts, and other foods that are full of fiber, protein, and other pound-dropping nutrients. These options will help you prevent cravings and keep you full straight through your usual afternoon snack.
