Salt Reduction Day (Genen no Hi) — 17th of Every Month

What Is Salt Reduction Day?

The 17th of every month is observed as "Salt Reduction Day." It was established by the Japanese Society of Hypertension to raise awareness of reducing salt intake, which is essential for preventing and treating high blood pressure, and was recognized by the Japan Anniversary Association in 2017. The date comes from May 17th — both World Hypertension Day, set by the World Hypertension League, and Japan's "Hypertension Day," set by the society — with the 17th of every month chosen so that salt reduction continues all year round. Japanese people tend to consume more salt than people in many other countries, so this day serves as a recurring reminder to "subtract" salt from daily meals and pursue a long, healthy life.

Salt Intake and the Body

Japanese food culture has long been closely tied to salt through the development of preserved foods and seasonings.

• Average intake among Japanese people: According to surveys by the Ministry of Health, Labour and Welfare, the average daily salt intake among Japanese adults continues to exceed the recommended target, making salt reduction a long-standing national health issue.
• The link to high blood pressure: Too much salt (sodium) makes the body retain water to keep concentrations balanced, which tends to raise blood pressure. High blood pressure is a major risk factor for stroke and heart disease.

Tips for "Delicious Salt Reduction"

With some thought about how flavors are built, you can cut salt while keeping meals satisfying.

• The power of umami (dashi): By making the most of umami compounds like glutamic acid (from kelp) and inosinic acid (from dried bonito), dishes are said to feel less bland even with less salt.
• Potassium's role in excretion: Potassium, found abundantly in vegetables and fruits, is said to help the body excrete sodium (people with kidney disease should consult their doctor).

Interesting Facts About Salt Reduction

• The official target: Japan's "Dietary Reference Intakes for Japanese" sets the daily salt target at under 7.5g for men and under 6.5g for women, while the WHO recommends an even stricter limit of under 5g. The Japanese Society of Hypertension recommends under 6g a day for people with high blood pressure.
• "Hidden salt": Processed foods like bread, udon noodles, and ham contain significant amounts of salt from the manufacturing process, so it's important to watch for salt beyond what you add at the table.
• Using acidity and spices: Layering in the tartness of lemon or vinegar, the kick of pepper or chili, and the aroma of shiso or ginger can add depth of flavor while cutting back on salt.
• Your palate adapts: People who keep eating lightly seasoned food are said to get used to it and notice the natural flavors of ingredients more.
• Local activities: Around the 17th, some local governments share low-salt recipes and some supermarkets set up low-salt food corners.

Tips for Enjoying Salt Reduction Day

• Try steaming dishes to bring out natural flavors, or grilling to add aroma — cooking methods that don't rely on salt
• In honor of the 17th (Salt Reduction Day), get into the habit of checking the "salt equivalent" listed on nutrition labels when shopping
