12 Foods to Boost Your Immune System
The health benefits of chilli pepper are often underestimated. Chilli pepper is high in antioxidants and packed with vitamin C. It contains even more vitamin C than a lemon. You naturally wonder why they always say that vitamin C is so healthy. Well, vitamin C stimulates the production of white blood cells, which in turn ensures that your body builds up resistance.
2. underestimate：低估。由under(下)+estimate(估计)结合而成。
3. be high in：在...（含量）高，等于下文的 be rich in。
4. be packed with：充满。等于be filled with
6. naturally：自然地。natural的副词形式。
8. production：产生，产量。是produce的名词形式，另一个名词：product则是“产品”的意思。两者须注意辨别。
11. ensure：保证。( en + n. / adj. = v.) 例如: enlarge （扩大），enrich（丰富），enjoy（使开心），encage（把..关进笼子），encourage（鼓励）。
Carrots are not only good for your eyes, but they also give your immune system a boost. Carrots are the best source of beta carotene. That is an antioxidant that is converted into Vitamin A in your body. This vitamin ensures that you always have enough white blood cells in your body.

Kale is a real superfood, but much cheaper than goji berries and chia seeds. By eating 125 grams of kale you achieve 90 per cent of the recommended daily amount of vitamin C and 350 per cent of the recommended daily amount of vitamin A. We always think fruit is packed with vitamin C. Still, kale contains much more vitamin C than the same weight of an orange.
注解：
- much cheaper：便宜多了。much是用来修饰比较级cheaper，表示比较的程度。除此之外还有 far，rather，even，still，a lot，a little，a bit，这些单词在考试中，都是要用比较级的标志。
- chia seed：奇亚籽（见下图），实物我也没见过。
 - by eating：通过吃...。by + doing表示“通过做某事” 来达到什么目的，一直都是考试的重点。
- still：原意是仍然，置于句首表示“然而”，等于 however，on the other hand，on the contrary。
Mushrooms are very healthy because they are low in calories and fat and rich in minerals, vitamins and fibre. Therefore, they also count as the recommended two ounces of vegetables per day.

7. per day：每天，等于every（single）day
