Varied diet is the best choice for the one who tells ” I eat a healthy diet, but I tend to eat the same foods over and over” She was also asking am I right or should I change my diet?. You should change your diet always because a varied diet is supposed to be best, for two reasons. First, because different food groups tend to feature different nutrient profiles. Second, because some healthful foods contain compounds that may pose a concern if you consume it in large quantities. For example, eating tuna every day may cause health issues, because tuna includes a small amount of mercury and mercury can damage your nerve system.
Another thing you should put in an account is, that the same food may not have the same nutrients. It does not matter if an apple has the same form and name as another apple. What matters, in the soil, not the name. That is why it is a good idea to buy your food from different sources in order to target different soils. The fruits and vegetables tend to take what the soil provide or supply with.
There is a proverb that says “we are what we eat” that is true. That can be applied also on the chicken you buy. Chickens from different sources have different nutrients. Even some chickens include more chemicals than the other chickens. Another example applies to eggs. The eggs differ according to the source they come from. We conclude that the variety is the best because you cannot memorize which food contain which nutrients. That is why the variety of food is a good strategy and an easy way to avoid exposure to a potential hazard. Fruits and vegetables contain lots of antioxidants and minerals, try to include them in your diet and try to eat a varied diet to feature all the nutrients.
