A recent episode of the Japanese TBS program The Doctor’s Big Stamp of Approval featured a compelling consensus: a poll of 300 medical professionals tasked with naming the healthiest foods. The results blend cutting-edge nutritional science with ancient culinary wisdom, culminating in a list that champions fermented, whole, and nutrient-dense ingredients.
The Doctor-Approved Top 10
Here is the full ranking of foods the medical community trusts the most, complete with expert commentary:
-
10. Apples: Dr. Takuji Shirasawa highlighted pectin for stabilizing blood sugar and preventing stroke, while Dr. Yoshio Otani praised the polyphenols for fighting bronchitis and hypertension.
-
9. Kimchi: A fermented powerhouse delivering a massive probiotic payload—1 billion lactic acid bacteria per gram—to enhance digestion and immunity.
-
8. Avocado: Recognized for anti-inflammatory unsaponifiable compounds that support joint health, alongside its detoxifying and cholesterol-lowering effects.
-
7. Tomatoes: Dr. Toshio Akiharu cited lycopene for actively reducing harmful LDL cholesterol while boosting good HDL, supporting vascular health and stroke prevention.
-
6. Broccoli: Dr. Gota Mizushima lauded its antioxidants for promoting circulation and hair growth, while nutritionist Arlene added that it is packed with iron, calcium, and fiber.
-
5. Vinegar: Professor Yoshiyuki Koizumi explained that acetic acid improves blood circulation and pressures; Dr. Takeshi Kurihara added that it boosts metabolism and reduces visceral fat.
-
4. Kōyadōfu (Freeze-dried Tofu): Dr. Minoru Kamata praised this ingredient for its “resistant protein” that improves cholesterol levels. Its freeze-drying process concentrates nutrients, yielding five times the calcium and seven times the iron of regular tofu.
-
3. Yogurt: Professor Yoriyo Miura of Japan Women’s University highlighted the benefits of lactic acid bacteria for gut health, constipation relief, and its potential to target visceral fat.
-
2. Mackerel: Dr. Fumihiko Hirata emphasized the high levels of EPA and DHA in mackerel, crucial for maintaining flexible arteries and preventing cardiovascular disease.
-
1. Nattō (Fermented Soybeans): The most divisive item on the list took the top spot. Physicians prized it for its enzyme nattokinase, which helps prevent blood clots and myocardial infarction, alongside benefits for bone density and blood sugar regulation.
Beyond the List: Breakfast & Protein Rich Foods
The survey didn’t stop at a general top 10. The program also featured a Top 20 Healthiest Breakfast Foods, compiled from the habits of 582 long-lived Japanese individuals, and a 17 High-Protein Foods ranking. These side lists emphasize that eating well means focusing on nutrient density at every meal.
What This Means for Your Plate
The overarching message from these 300 doctors is clear: a diet rich in fermented foods, omega-3s, and colorful plant matter is the foundation of health. While fresh nattō might be an acquired taste for the Hong Kong palate, most items on this list are readily accessible. Start simple by adding kimchi to your rice bowl, swapping morning toast for yogurt, or cooking more mackerel. The consensus provides a powerful, actionable guide to eating for longevity.
