Regarding "healthy" snacks, it should be noted that not all snacks are really healthy. Some snacks contain high sugar, high fat and other bad ingredients, and may even contain additives, pigments and other bad ingredients. Long-term consumption may bring potential risks. However, some snacks are healthy choices, such as nuts, dried fruits, plain yogurt and oatmeal cookies. These snacks are low in calories, provide essential protein, vitamins and fiber, and are easy to carry and eat.

When choosing snacks, you can pay attention to the following points:

1. Choose low-calorie, low-fat and low-sugar foods, such as dried nuts.

2. Pay attention to the ingredients of food and avoid toxic substances such as additives and pigments.

3. Snacks eaten every day should be controlled within an appropriate weight range and should not be eaten in large quantities.

In short, keeping healthy in the office and choosing "healthy" snacks is one of the effective means for office workers to keep healthy. Choosing and eating snacks correctly and taking appropriate health care measures are all helpful to health.
