Many people avoid healthy eating because the food may not taste as good as what they are used to, foods high in sodium, sugar, and calories, all of which, when taken in excess, can be harmful to health in the long term.
But, as the article explains, tastes buds can adapt. In fact, taste buds can learn to enjoy healthy unprocessed foods in time by eating more natural home-cooked meals. I've experienced this myself. I definitely ate a lot of processed foods before becoming vegan. Even when I started out as a vegetarian before becoming vegan, I ate veggie pizzas, garden burgers from the store, and a lot of other food products that were quick to prepare or just convenient. After a while, I noticed that I wasn't feeling that great, even though I was living primarily on a plant-based diet.
They key was to reduce sodium and sugars. Lately, I've stopped buying processed convenience foods. Some of the ingredients I buy for cooking are processed, such as tofu, coconut milk, tomato products, olive oil, and vinegar. But consuming an entire processed meal is something I avoid and it made me feel better. Further, by reducing salt slowly and learning to enjoy the natural flavor of foods, I didn't miss sodium and realized that it's a very harsh seasoning ingredient. The same applies to sugar. One could contend that my journey to becoming vegan was part of a bigger journey to eliminate salt and sugar from my diet which may be one of the best health habits.
When you reduce the amount of salt and sugar, you actually start eating less because the food becomes less addicting. Salt and sugar encourage you to take another bite quickly, even when your stomach has been filled. So weight control becomes easier to accomplish when these two ingredients are removed.
With all of this, it's important to understand that the human body adapts. So why not have it adapt to a healthy way of eating. It will love you back for doing so!
