​The answer is all the vegetables’ skin should be eaten.
The vegetables’ skin contains important substance called Phytochemical.
 
Phytochemical is called the seventh nutrition and has 3 effects.
(1) Phytochemical has strong anti-oxidant action and neutralizes active oxygen which rusts our body, keeping our body young.
(2) Phytochemical has anti-inflammatory action to suppress the inflammation such as arthritis.
(3) Phytochemical suppresses the increase of cancer cells.
 
Recommended vegetables to eat the skin
Pods of Edamame
Skin of onion: it contains a strong phytochemical called quercetin.
 
Make Vegetable bros
Boil the brown part of the onion and other skins of vegetable you usually throw away for 30 minutes.
You can keep it in the refrigerator and use it when you make soup.
 
Apple’s skin contains apple polyphenol which is considered as making our life longer.
In the case of fruits that you don’t eat skin, put them all in the blender and make juice.
In the case of melon, watermelon or honeydew, the part close to the skin contains a lot of phytochemicals so put them in the blender.

It takes about a month until you have spots on the skin after being exposed to UV rays. That means spots caused by UV rays in July and August are being made right now. So aftercare plays a very important role to prevent spots on the skin.
 
How are skin spots made?

​The skin tries to put up a black umbrella to protect the skin from strong UV rays. The black umbrella is the pigment melanin. The pigment melanin tries to protect the skin from the UV rays, but when the pigment melanin stays, it becomes a spot on the skin. So we should close the black umbrella (the pigment melanin), but there is a substance which interferes with closing the black umbrella.
 
Which is the same as the substance causing the spots on the skin?
(A) Moles on tiles
(B) Burns of a bread
(C) Collar stains of a white shirt
 
The answer is (B) Burns of a bread. It is called Maillard reaction. It recently turned out that spots on the skin and aging were caused by Maillard reaction in the body. “Burns of a bread” in the body is a substance called AGE. If you have a lot of AGE in your body, you easily have spots on the skin.
 
The important point of aftercare to prevent spots on the skin is not to store AGE in the body.
 
How can we not store AGE in the body?
Advanced glycation end products (AGEs) are proteins or lipids that become glycated as a result of exposure to sugars. In other words, when sugar attaches to collagen (proteins), the collagen transforms into AGE.
 
If there is AGE, excessive melanin is secreted by a little bit of exposure to UV rays. Now our skin is in the condition that black umbrellas (pigment melanin) are open to protect the skin from UV rays we were exposed to during summer. That means the skin is suppressing the absorption of UV rays by making the skin dark. Spots are not supposed to occur if the umbrellas are closed, but if you have a lot of AGE in the body, the skin tries to put up the black umbrellas even though UV rays are weak, leaving spots on the skin easily.
 
Therefore, medically correct aftercare for the skin is closing the black umbrellas by decreasing AGE and trying not to leave spots.
 
The point for the aftercare is not to take too much food containing AGE.

​Meat dishes contain a lot of AGE.
 
Amount of AGE: Vegetable<Carbohydrate<Fish<Meat
 
But if you devise how to cook meat, you can decrease the amount of AGE.
The amount of AGE becomes one tenth by boiling and steaming meat, compared to frying meat.
 
But there is a method to reduce AGE of oily dishes. Cooking after precooking meat with vinegar reduces AGE. If you eat meat dishes with vinegar or lemon, etc., you can prevent excessive intake of AGE because it becomes difficult for collagen to attach to sugar. Just pouring lemon juice on a fried dish reduces AGE.
 
Also it can be expected that Chitin and Chitosan contained in mushrooms are effective to suppress the absorption of AGE. 

The skin strong against UV is dark skin becoming darker instead of red when exposed to sunlight. The skin weak against UV is fair skin becoming red when exposed to sunlight. The reason that the skin becomes red is that DNA of the skin is damaged.
 
The method that the person who is easily affected by UV changes to the person who is strong against UV is soaking in bathtub.
 
Heat shock protein that is a protein increasing by the stimulation of heat. Usually heat shock protein increases when the cells are damaged by bacterial infection or others and repairs the damaged cells. The increase of heat shock protein elevates the ability to repair the damaged skin cells. Therefore, the skin becomes strong against UV.
 
The easiest way to increase heat shock protein is soaking in a bathtub once in three days.
If you soak in a bathtub every day, your body gets used to the heat stimulation and heat shock protein doesn’t increase easily. Also the amount of heat shock protein is peak 2 days after soaking in a bathtub and returns to the original amount in 7 days. So 3 days later when heat shock protein starts to decrease is a good timing to stimulate again by soaking in a bathtub to keep sufficient amount of heat shock protein in the body.
 
Soaking in water of 41 degrees C (105.8 degrees F) for 15 minutes once in 3 days is effective to increase heat shock protein. Taking a shower on other 2 days with water of 37 degrees C is recommended not to get used to water of 41 degrees C.
 
The female B whose photoaging is progressed tried the above bathing method for 2 weeks.
The important points at the time of bathing are taking water, taking rest outside of the bathtub when it feels hot and sweating on the face that is the proof that heat shock protein increases.
As the result of the 2 weeks trial of the bathing, her skin became strong against UV as shown in the comparison between the before and after the test of exposure to weak UV for 1 minute (Fig. 2). Also heat shock protein in her blood increased by 1.3 times.

​Photoaging is changes in the skin induced by long-term ultraviolet ray (UV) exposure. When illuminated with UV, a substance called collagenase is activated and collagen is broken down. Accumulation of this process for a long time causes spots and flabbiness on the skin. But the effect of UV is not only spots and flabbiness on the skin.
 
What increases these days is base-cell carcinoma. When illuminated with UV, DNA of the skin cells is damaged. If the damaged cells are repeatedly divided, skin cancer occurs.
 
Langerhans cells are immune cells protecting the body from viruses and others. When they are illuminated with UV, the number of Langerhans cells decreases so the function of the immune system becomes weaker.
 
Pitfalls of countermeasure against UV
 
There are two 50’s females who pay attention to prevent UV, wearing sunscreen and using a parasol when they go outside. But there is a big difference about the quantity of collagen under the skin between these two females. If you keep being exposed to UV, breakdown of collagen is progressed. That makes the difference about photoaging.
 
What makes the difference about photoaging between these two females?
 
1. Movement of the Sun and pattern of behavior in the house
The female A whose photoaging is not progressed moves at the other side of the Sun. on the other hand, the female B whose photoaging is progressed moves in the room getting sunlight.
 
There are two types of UV. UVB mostly doesn’t pass through windows, but UVA passes through windows and pours into a room. UVA doesn’t make the skin red so there can be exposure to a large amount of UVA without notice. The female B is likely to be exposed to a large amount of UVA in the house.
 
2. How to use a parasol
UV comes from all the directions by reflection. If you use a parasol at the high position, you can’t prevent UV coming from sides and below. While the female A whose photoaging is not progressed use a parasol at lower position, the female B whose photoaging is progressed use a parasol at high position. This makes big difference about UV strength around their faces. Also the female A whose photoaging is not progressed changes the direction of her parasol to make it face direct sunlight.(Fig. 1)
 
Quiz for UV measure

Q1. Which place has the strongest UV?
(A) On the sea shore
(B) At the top of a mountain
(C) In the city
 
A1. (B) At the top of a mountain
Since the altitude on the top of a mountain is high, the air is clear, containing less dust and fluff in the air so that UV is not absorbed. That makes UV strong at the top of a mountain.
 
Q2. Being by the window exposes you to UV. Which can prevent UV more?
(A) Closing only the window
(B) Closing only the lace curtain
 
A2. (A) Closing only the window
Windows absorb most UVB which becomes a cause of sunburn and skin cancer. Closing both the window and lace curtain is more effective. (UV intensity in the experiment: Only window 0.86, Only curtain 1.30, Both 0.18)
 
Q3. It is important to choose the material of clothes to protect the skin from UV. Which material doesn’t pass UV most?
(A) Cotton
(B) Silk
(C) Polyether
 
A3. (C) Polyether
Polyester absorbs UVB which is most dangerous to the skin. But polyester doesn’t absorb sweat so it is recommended to wear mixed material of cotton which absorbs sweat and polyester which absorbs UVB.

When you had a sunburn, the most effective method to prevent spots and wrinkles is eating mini tomatoes.
 
Lycopene contained in mini tomatoes which is a kind of polyphenols lightens the redness caused by a sunburn and also prevents the dryness of the skin, resulting in preventing wrinkles. Since lycopene also has the function to reduce melanin which is a cause of spots, eating mini tomatoes is effective to prevent spots.
 
Mini tomatoes are rich in vitamin C which is called “Beauty Vitamin” and magnesium which raises the metabolism of the skin.
 
Lycopene is contained in the part of the skin of tomatoes so you can get more lycopene by eating mini tomatoes than by normal tomatoes.
 
Nutrition (per 100 g)
Mini tomato (Lycopene: 22 mg/Vitamin C: 32 mg/Magnesium: 13 mg)
Normal tomato (Lycopene: 10 mg/Vitamin C: 15 mg/Magnesium: 9 mg)
 
Eating 15 mini tomatoes a day is effective.
