the first item is: brightly colored food.

in the BBC documentary, the representative thing is tomato.

The main reason why tomatoes are brightly colored is that they have a special ingredient: lycopene.

Lycopene can well absorb oxidation and prevent oxidative stress reaction, and has a good effect of repairing fibroblasts.

The vegetables listed by BBC here are actually not bitter, but a healthy vegetable that fitness people often include in their recipes: broccoli and radish.

They contain an ingredient called glucosinolate, which is a natural anti-aging and antioxidant substance.

After ingesting this ingredient, glucosinolates will be stored in the skin, which enables the skin to protect itself.

The anti-aging effect can be achieved by eating a lot of oily fish.

Fish contains a special substance: omega-3 fatty acids.

Some fish can even have anti-inflammatory effect. Inflammation will lead to oxidative stress reaction of the skin, while fish-specific substances can eliminate inflammation in skin cells, which is naturally beneficial to anti-aging.

the first three items are recommended foods for everyone to eat.

the fourth item is the food that people should avoid:

starchy food, such as potatoes, rice and pasta.

You'll never believe it: sugar

But BBC research shows that sugar intake also determines skin aging.

The most obvious thing is that when diabetic patients guess options and match their ages through their looks.

The conclusion is that diabetics generally look older than their peers.

Later, the study directly tested the relationship between blood sugar and skin, and found that the relationship between blood sugar and appearance age was very significant.

To fight against time, we should make the following summary:

1. Pay attention to sun protection

2. Eat more brightly colored foods and fatty fish, as well as bitter food like broccoli.

3. Reduce the intake of starch

4. The most important thing is to abstain from sugar.
