The Traditional View: Squid as a 'Heaty' Food
Within Traditional Chinese Medicine (TCM) and other traditional systems, foods are categorized by their perceived thermal properties, such as being 'heaty' (warming) or 'cooling'. This classification does not relate to the food's literal temperature but rather the energetic effect it is believed to have on the body after digestion. Foods categorized as 'heaty' or 'warming' are thought to nourish yang energy and can produce symptoms like thirst, acne, or inflammation if consumed in excess.
According to some interpretations, seafood like prawns, crabs, and squid are considered 'heaty'. For this reason, practitioners of TCM might advise individuals with a 'heat constitution' or during the summer months to limit their intake of these foods. The rationale is to maintain a balance of yin (cooling) and yang (warming) within the body and to prevent an overabundance of heat.
The Modern Scientific Perspective: Anti-Inflammatory Benefits
In stark contrast to traditional classifications, modern nutritional science evaluates food based on its biochemical components and their physiological effects. From this standpoint, squid is not a 'heaty' food but rather a nutrient-dense protein source with several health benefits, many of which are explicitly anti-inflammatory.
Key Nutritional Components of Squid
- Rich in Omega-3 Fatty Acids: Squid is a notable source of omega-3 fatty acids, specifically EPA and DHA. These polyunsaturated fats are well-documented for their anti-inflammatory properties, which can help soothe conditions like rheumatoid arthritis and reduce overall systemic inflammation.
- High-Quality Protein: With 16-18 grams of protein per 100-gram serving, squid supports muscle building, cellular repair, and overall body function.
- Vitamins and Minerals: Squid is packed with essential micronutrients, including vitamin B12, selenium, potassium, and copper.
- Antioxidants: The ink of the squid contains powerful antioxidants that protect cells from damage caused by free radicals and oxidative stress.
Traditional vs. Modern: A Comparison
| Aspect | Traditional Belief (e.g., TCM) | Modern Nutritional Science |
|---|---|---|
| Body Effect | Perceived as 'heaty' and potentially causes internal heat and inflammation in sensitive individuals. | Considered anti-inflammatory due to omega-3 fatty acid content. |
| Primary Reason | Classification based on observed energetic effects and the principle of balancing yin and yang. | Analysis based on specific biochemical compounds like omega-3s. |
| Dietary Guidance | Avoid in excess during summer or for those with a 'heat constitution'; cooking methods can impact the food's 'heatiness'. | Consume in moderation as part of a balanced diet; preparation can influence overall healthiness (e.g., grilled vs. deep-fried). |
How Cooking Methods Impact Perception
The way squid is prepared can significantly influence how the body and mind perceive it. While traditional beliefs focus on inherent properties, modern science explains how preparation can change the nutritional profile. For example, deep-fried calamari, often prepared with heavy batter and oil, might feel 'heaty' not because of the squid itself, but due to the processed, oily nature of the preparation. In contrast, steamed or grilled squid, which is less processed, delivers the nutrients without added fat. This aligns with the potential cultural observation from Vietnam that seasoned squid can be eaten to "overcome the heat" of the season, suggesting a different, potentially less oily, preparation.
Conclusion: Balancing Tradition and Science
The question of whether is squid heat for the body reveals a fascinating contrast between ancient wisdom and modern scientific understanding. While traditional systems classify it as 'heaty' based on energetic principles, scientific research provides clear evidence of its anti-inflammatory properties, thanks to its rich omega-3 content. For the average person, the nutritional benefits of moderate squid consumption, such as heart health and reduced inflammation, are well-supported by science. Ultimately, balancing cultural beliefs with evidence-based nutrition allows for a holistic approach to diet and wellness.

What are the Anti-Inflammatory Effects of Squid?
- Squid oil is rich in omega-3 polyunsaturated fatty acids, particularly DHA and EPA, which are known to modulate inflammatory responses in the body.
- Studies have shown that omega-3 supplementation, including from marine sources like squid, can lower markers of inflammation.
- Antioxidants found in squid ink also help protect against cellular damage caused by free radicals.
Is Squid Healthy?
- Yes, squid is a low-fat, high-protein seafood that is rich in vitamins, minerals, and omega-3 fatty acids.
- It supports heart health, brain function, and has anti-inflammatory properties.
- As with any seafood, moderation is key due to potential concerns like cholesterol content.
