potassium It has the effect of excreting excess salt, maintaining a balance with sodium, and stabilizing blood pressure. If you have weak kidneys , you need to be careful with your intake as it can be excessive and damage your heart.
calcium Calcium is not only a material for bones and teeth, but also plays an important role in nerve information transmission. Calcium increases the risk of orthopedic diseases not only when it is insufficient, but also when it is overdose .
β-carotene Dogs can synthesize beta-carotene into vitamin A in their bodies. Vitamin A helps maintain healthy coats and vision. Deficiency leads to weakened immune system and imperfect bone formation.
Alpha Tocopherol (Vitamin E) Vitamin E, also called tocopherol, has an antioxidant effect and is expected to have anti-aging, anti-dementia, and anti-inflammatory effects on skin diseases such as atopic dermatitis. Absorption efficiency is low when taken alone, and absorption is promoted when taken with fat.
folic acid It plays an important role in supporting the rebirth and growth of body cells, and is called the ” hematopoietic vitamin .” Deficiency leads to anemia and weakened immune system.
Vitamin C It has a strong antioxidant effect and is expected to have cancer prevention and anti-aging effects. It also has the effect of detoxifying foreign substances in the body and improving the immune function. Dogs can synthesize it in their own bodies .
Dietary fiber It acts as food for intestinal bacteria, improves the intestinal environment, and prevents diabetes by slowing the rise in postprandial blood sugar. Water-soluble can be expected to have effects such as continued satiety and improvement of diarrhea, and insoluble can be expected to improve constipation. Daikon radish leaves contain 4.0g of dietary fiber per 100g, which is more than 1.8g per 100g of cabbage.

Digestive enzymes contained in radish

Radish contains various digestive enzymes. It is vulnerable to heat, so if you want the effect, you should eat it raw.

Amylase (Diastase)

Amylase (diastase) is an enzyme that breaks down starch, and in the case of humans, it is contained in saliva, but it is not contained in dogs and is secreted only from the pancreas. When eating rice containing a lot of starch such as grains, it supports the digestion and absorption of the gastrointestinal tract .


Proteases are enzymes that break down proteins. Dogs are omnivores, but because they were originally carnivorous, they have a high protein requirement, and enzymes promote digestion and absorption, which reduces the burden on the liver and kidneys .


The spiciness of daikon radish comes from a component called isothiocyanate, which is expected to have antibacterial and anti-carcinogenic effects (*) . Isothiocyanates are produced when cells are broken, so you can get a lot of them by grated daikon radish. This is why it is said that you don’t need a doctor to grate daikon radish . If the stomach is weak, the stimulation will be too strong, so be careful not to give too much.
