The Health Benefits of Sushi: A Deep Dive with Chef Takamasa Maezaki | Sushi Making Class in Los Angeles

In the bustling city of Los Angeles, where the culinary scene is as diverse as its population, sushi has become a staple for many food enthusiasts. But beyond its delicious taste, sushi offers numerous health benefits. To get a deeper insight into these benefits and learn how attending a sushi class can encourage healthier eating habits, we sat down with Chef Takamasa Maezaki, owner of Chef Maezaki's website and CM ghost kitchen, a popular sushi takeout restaurant in Pasadena.

Omega-3 Fatty Acids: The Heart and Brain

The cornerstone of sushi's health benefits lies in its primary ingredient: fish. Chef Maezaki emphasizes, "Fish like salmon and mackerel are rich in omega-3 fatty acids, essential fats our body can't produce by itself." These fats are crucial for maintaining heart health by reducing blood pressure, lowering cholesterol levels, and decreasing the risk of heart disease. Beyond heart health, omega-3s play a significant role in brain function, aiding in memory, cognitive performance, and even emotional well-being.

"During our sushi classes, we delve into the importance of these fatty acids, teaching our students not just to make sushi, but to understand its benefits," Chef Maezaki shares. This hands-on experience provides an invaluable lesson in selecting the right kind of fish to maximize these health benefits.

The Hidden Virtues of Sushi Rice

At first glance, sushi rice might seem like a simple carbohydrate, but it's a vehicle for subtle health benefits. "Sushi rice is seasoned with vinegar, which has antimicrobial properties and can aid in digestion," explains Chef Maezaki. The vinegar content helps balance the body's pH levels and promotes a healthy gut, which is fundamental to overall health.

The vinegar in sushi rice acts as a natural preservative and has been shown to inhibit the growth of harmful bacteria in the gut. This is crucial not only for preventing foodborne illnesses but also for maintaining a balanced intestinal flora. "By incorporating vinegar into the rice, we're not just enhancing its flavor; we're also adding a layer of protection that supports the digestive system," Chef Maezaki elaborates. This aspect of sushi preparation reflects the traditional Japanese wisdom of using natural ingredients to promote health and well-being.

Furthermore, the acidic nature of vinegar plays a pivotal role in maintaining a healthy pH balance in the stomach. A slightly acidic environment is essential for the optimal functioning of digestive enzymes and the absorption of nutrients from food. "The vinegar in sushi rice helps ensure that the stomach's pH levels are conducive to digestion, facilitating the breakdown of food and the efficient absorption of its nutrients," says Chef Maezaki. Additionally, this balanced pH environment promotes a healthy gut by discouraging the growth of pathogenic bacteria and encouraging the proliferation of beneficial gut flora. In essence, the careful seasoning of sushi rice with vinegar not only elevates the culinary experience but also integrates a functional component that supports digestive health and overall well-being.

Vegetables and Seaweed: A Nutritional Powerhouse

Sushi is often adorned with or wrapped in vegetables and seaweed, each adding its own nutritional punch. "Nori, the seaweed used in sushi, is more than just a wrapper; it's a rich source of iodine, crucial for thyroid health, as well as vitamins A, C, and E," says the chef. Vegetables commonly found in sushi, such as cucumber, avocado, and asparagus, contribute fiber, vitamins, and minerals. These elements are essential for maintaining a healthy digestive system, ensuring skin health, and providing anti-inflammatory benefits.


Iodine, abundantly found in nori (the seaweed used to wrap sushi), is a trace element that is vital for the synthesis of thyroid hormones. These hormones regulate metabolic processes, energy production, and are essential for growth and development. "A deficiency in iodine can lead to thyroid disorders such as hypothyroidism, which makes the iodine in nori an invaluable component of sushi," Chef Maezaki points out. This highlights the role of sushi not just in satisfying our palates but also in supporting our metabolic health.

Vitamins A, C, and E

Moreover, the vitamins A, C, and E present in vegetables and seaweed are powerful antioxidants that play significant roles in maintaining skin health and bolstering the immune system. Vitamin A is crucial for skin regeneration and vision, Vitamin C supports the production of collagen for skin elasticity and wound healing, and Vitamin E protects the skin from oxidative stress caused by free radicals. "These vitamins, combined with the anti-inflammatory properties of omega-3 fatty acids found in fish, make sushi a skin-health promoting meal," explains Chef Maezaki. This combination can help in reducing inflammation in the body, which is beneficial not only for skin health but also for preventing chronic diseases.


Fiber, found in the vegetables used in sushi, such as cucumber, avocado, and asparagus, is another crucial element for a healthy digestive system. Fiber aids in digestion by helping to maintain regular bowel movements and can also contribute to a feeling of fullness, which helps in weight management. "The fiber in these vegetables supports a healthy gut microbiome, which is essential for overall health, including immune function and mental health," Chef Maezaki adds. Furthermore, the minerals such as potassium, magnesium, and selenium found in these sushi components contribute to cardiovascular health, muscle function, and protection against oxidative damage, respectively.

Portion Control and Mindful Eating

An often-overlooked benefit of sushi is its role in promoting portion control and mindful eating. Sushi's presentation and size encourage us to savor each piece, paying attention to the flavors and textures. "It's a lesson in enjoying food with intention, recognizing satiety cues, and appreciating the quality over quantity," Chef Maezaki notes. This approach to eating can lead to healthier choices and a more balanced diet overall.

The List of Sushi's Health Benefits

After our deep dive into the health benefits of sushi with Chef Maezaki, it's clear that this beloved dish is much more than meets the eye. Here's a detailed list of the nutritional benefits sushi offers:

  • Omega-3 Fatty Acids: Supports heart health, improves brain function, and reduces inflammation.

  • Protein: Essential for muscle repair and growth, provided by the fish and seafood components.

  • Vinegar Seasoned Rice: Aids in digestion and has antimicrobial properties.

  • Iodine: Found in seaweed, supports thyroid function and metabolic health.

  • Vitamins A, C, and E: Antioxidants present in vegetables and seaweed, promoting skin health and immune function.

  • Minerals: Such as magnesium and selenium, crucial for various bodily functions including metabolic health and antioxidant defense.

  • Fiber: Present in vegetables, aids in digestion and promotes a feeling of fullness, contributing to weight management.


Sushi is not just a culinary art form but a composite of carefully chosen ingredients that offer a plethora of health benefits. Chef Takamasa Maezaki's insights reveal that behind every roll and nigiri lies a story of nutrition and wellness. "Attending a sushi class in Los Angeles isn't just about learning to make sushi; it's an education in making healthier food choices that nourish the body and soul," he concludes.

As we explore the vibrant sushi scene in Los Angeles, it's worth remembering that each piece of sushi we enjoy is a step towards a healthier lifestyle, thanks to the natural goodness packed in each bite.
