What is soy isoflavone: why it gets attention during menopause
Soy isoflavone is a type of polyphenol found in soybeans and soy-based products (tofu, natto, miso, soy milk, etc.). Its chemical structure resembles the female hormone estrogen, earning it the name "phytoestrogen."
Menopause is a period of rapid estrogen decline, and the potential of dietary soy isoflavone to support symptoms has been studied extensively. However, effects vary between individuals and are not guaranteed for everyone.
Recommended daily isoflavone intake (reference): According to Japan's Food Safety Commission, the "safe upper intake guideline" for soy isoflavone is approximately 70 to 75mg per day (when consumed from soy-derived foods). One block of tofu (about 150g) contains approximately 40mg of isoflavone.

Tofu: the easiest way to get soy isoflavone
Tofu is a concentrated source of soy nutrition, with one block (150g) containing about 40mg of isoflavone. It is also rich in protein and supports weight management, a common concern during menopause.
Choosing tofu in HCM
In HCM, both Japanese-style tofu (kinugoshi, momen) and Vietnamese tofu (different texture) are available. When cooking Japanese dishes, choosing Japanese-style tofu is important.
| Type | Characteristics | Suitable dishes |
|---|---|---|
| Silken tofu (kinugoshi) | Smooth, breaks easily | Hiyayakko, miso soup, smoothies |
| Firm tofu (momen) | Sturdy, holds up when stir-fried | Stir-fry, agedashi tofu, mapo tofu |
Simple recipe: hiyayakko (cold tofu)
A perfect no-cook dish for the hot HCM climate.
- Chill silken tofu well in the refrigerator
- Cut into bite-sized pieces and arrange on a plate
- Top with grated ginger, chopped green onion, and katsuobushi
- Drizzle with soy sauce (Kikkoman, etc.) and serve
Preparation time under 5 minutes. An easy dish even when appetite drops due to the HCM heat.

Natto: the dual benefit of isoflavone and probiotics
One pack of natto (about 40g) contains approximately 30 to 40mg of isoflavone, plus probiotic benefits from natto bacteria, vitamin K2, and dietary fiber. For women concerned about bone density decline during menopause, the vitamin K2 content (involved in bone metabolism) is noteworthy.
Practical tip for HCM: Move frozen natto to the refrigerator the night before, let it thaw naturally, and eat it the next morning. Do not refreeze after thawing; consume within the day. Farmi delivers with cold chain support.
Simple recipe: natto and avocado mix
- Stir one pack of natto about 20 to 30 times
- Cut half an avocado into 1cm cubes and mix with the natto
- Season with the included sauce, a touch of wasabi, and a little soy sauce
- Sprinkle with shredded nori and serve
The combination of healthy fats from avocado with soy protein and isoflavone makes a highly satisfying dish.

Miso: building an isoflavone habit through daily meals
Miso is a fermented seasoning made from soybeans. The habit of drinking three bowls of miso soup per day is considered a foundation for isoflavone intake. The fermentation process also supports gut health, addressing digestive issues common during menopause.
Miso types and approximate isoflavone content
| Miso type | Approx. isoflavone per tablespoon (18g) |
|---|---|
| White miso (Kyoto/Kansai) | About 6 to 8mg |
| Mixed miso (awase) | About 7 to 9mg |
| Red miso (Nagoya/Tohoku) | About 8 to 10mg |
*Values are approximate. Actual content may vary by product.
A simple addition to your morning miso soup changes everything
Adding tofu to miso soup doubles the isoflavone in one bowl. Combining wakame (fiber, minerals), mushrooms (beta-glucan), and komatsuna (calcium) creates a nutritionally balanced bowl.
In HCM, mixed miso (awase) is the most versatile option. The Farmi app carries various Japanese miso brands.

Kinako: a soy powder you can easily add
Kinako (roasted yellow soybean powder) contains about 10 to 15mg of isoflavone per tablespoon (about 6g). Simply mix with sugar and sprinkle on yogurt or banana, making it easy to maintain even on days you do not feel like cooking.
Ways to use kinako (practical in HCM)
- Sprinkle on yogurt: add 1 tablespoon of kinako and a little honey to plain yogurt (Meiji Bulgaria, etc.)
- Banana kinako smoothie: blend banana, soy milk, and kinako for a quick breakfast
- Sprinkle on sticky rice: making ohagi is difficult in HCM, but soft-cooked sticky rice with kinako and sugar recreates the flavor
- Mix into hot drinks: dissolve kinako in hot milk (or soy milk) for an easy beverage
Kinako is available on the Farmi app (please check the app for current stock availability).

Soy milk: supplementing isoflavone through daily beverages
Soy milk (both adjusted and unsweetened) is an effective isoflavone source. One glass (200ml) contains approximately 20 to 25mg of isoflavone.
Local soy milk (dau nanh) is available in HCM, but its composition and taste may differ from Japanese brands. For Japanese soy milk (Kikkoman, Marusan, etc.), check the Farmi app.
Note: Consuming large amounts of soy milk is not necessarily better. Be mindful not to exceed the upper guideline (isoflavone 70 to 75mg/day) set by Japan's Food Safety Commission.

Frequently asked questions (FAQ)
Q. Does soy isoflavone definitely help with menopause? A. The effects of soy isoflavone vary significantly between individuals, and the same results cannot be guaranteed for everyone. If menopause symptoms are severe, combine dietary approaches with consultation from a gynecologist or your primary care physician. This article is not a substitute for medical advice.
Q. Is it safe to eat soy foods every day? A. According to Japan's Food Safety Commission, soy isoflavone from a normal diet is considered safe for healthy adults. However, caution is needed when combining with supplements or consuming excessively. Those with breast cancer or thyroid conditions should consult their doctor.
Q. Does silken (kinugoshi) or firm (momen) tofu have more isoflavone? A. Generally, firm tofu has less water content and therefore a higher isoflavone concentration per weight. However, both are good sources of soy isoflavone. Choose based on the cooking method that suits your dish.
Q. Is there a reliable way to get Japanese-style tofu in HCM? A. Japanese supermarkets or the Farmi app are the most reliable sources. Tofu at local supermarkets may differ in texture and composition. On the Farmi app, search in Japanese for "tofu" to find Japanese-style products (check the app for stock availability).
