Squid is a familiar and beloved seafood in Vietnamese family meals thanks to its delicious flavor, natural crispness, sweetness, and high nutritional value. However, according to both Eastern medicine and modern nutrition, combining food incorrectly can destroy nutrients, and may even cause poisoning or allergic reactions. So, what does squid conflict with? What should squid be avoided eating with to ensure the health safety of the whole family? Let’s join Ola Squid to find out the details through the article below.
What does squid conflict with? List of foods not to eat with squid
To avoid digestive issues or reducing the nutritional value of the dish, you need to understand what foods squid should not be eaten with before entering the kitchen to cook.
Foods rich in vitamin C (oranges, lemons, pineapples, tomatoes)
Seafood, including squid, contains a certain amount of harmless pentavalent arsenic compounds. However, when combined with foods rich in vitamin C such as oranges, lemons, pineapples, or tomatoes, vitamin C can convert this arsenic into arsenic trioxide (folkly called gypsum) which has the potential to cause poisoning reactions, allergies, or bloating.

Green tea and foods rich in tannin
Green tea contains a high amount of tannic acid (tannin). When drinking green tea right after eating squid, tannic acid will combine with the large amount of protein in squid to form poorly soluble protein tannate compounds. This compound causes irritation of the intestinal mucosa, reduces intestinal motility, easily leads to constipation, and hinders the body’s absorption of nutrients.

Beer, wine, and alcoholic beverages
Many people have the habit of sipping grilled squid with beer and alcohol at drinking parties, but this is an unhealthy combination. Squid contains a lot of purine, which when entering the body will be converted into uric acid. Alcoholic beverages hinder the excretion of uric acid through the kidneys. This accumulation of uric acid is the cause of acute Gout attacks and increases the risk of kidney stones.

Cold-natured foods (watermelon, cucumber, wax gourd, baby clams, crabs)
Squid is a cold-natured food. If squid is combined with cold-natured foods or fruits such as watermelon, cucumber, wax gourd, or other seafood such as baby clams, crabs, etc., it will cause “cold stagnation and accumulation”. This easily overloads the digestive system, causing a cold stomach, diarrhea, and dull abdominal pain.

Ginseng
Ginseng helps greatly supplement vital energy and enhance health, while squid is cold-natured and has the effect of lowering energy. These two foods have opposing Eastern medicine properties that cancel each other out. Consuming ginseng together with squid will reduce the tonic effect of ginseng, causing waste and even digestive stagnation.

Eggs
Although both eggs and squid are nutritious dishes, combining them in the same meal or preparation is not encouraged. Both contain high protein and rich cholesterol content. Ingesting a large amount of protein at the same time easily overloads the intestinal tract, causing bloating, indigestion, and is not good for the cardiovascular system.

Coriander (cilantro)
Many people wonder what herbs squid conflicts with when seasoning dishes? The answer is coriander (cilantro). Coriander is warm-natured with a pungent aroma. When cooked together with squid (which is cold-natured), this opposition in properties not only ruins the natural sweet and refreshing flavor of the seafood but also easily stimulates sensitive stomachs.

Water spinach
When researching what dishes or vegetables squid should avoid, water spinach is a name you need to note. Water spinach contains a lot of soluble fiber and compounds that can slightly increase inflammatory reactions or cause scarring. When eaten together with protein-rich squid, it will cause skin allergies and itching in people with sensitive constitutions.

Broccoli
Broccoli is rich in fiber and minerals, but it also contains sulfate groups and phytic acid. When stir-frying broccoli with squid, the fiber and these acids can bind with copper, zinc, and calcium present in the squid, reducing the body’s ability to absorb these minerals.

Dog meat, goat meat, buffalo meat
Dog meat, goat meat, or buffalo meat are protein-rich red meats that are extremely heat-generating (very hot). Squid is cold-natured. Consuming two excessively large sources of protein with conflicting properties simultaneously disrupts digestion and increases metabolic pressure on the liver and kidneys.

Who should limit eating squid?
Squid is a nutritious dish, but not everyone can enjoy it freely. Below are groups of people who need to be cautious or limit eating squid to protect their health:
- People with seafood allergies: Squid contains foreign proteins (especially tropomyosin). For people with sensitive constitutions, just a small amount of squid can cause symptoms such as hives, itching, swollen lips, or even difficulty breathing and anaphylactic shock.
- People with gout: Due to its relatively high purine content, people suffering from gout or with high blood uric acid levels should limit eating squid to avoid triggering acute gout attacks in the joints.
- Pregnant women, women menstruating or breastfeeding: During menstruation or pregnancy, a woman’s body is sensitive and needs to maintain warmth for the uterus. The cold nature of squid can cause worse menstrual cramps or a cold stomach, affecting the weak digestive system of pregnant and postpartum mothers.
- People with cardiovascular, liver, and biliary diseases: The cholesterol content in squid is quite high. People with a history of high blood lipids, atherosclerosis, hepatitis, and gallstones should limit eating squid so as not to increase the burden on the circulatory system and metabolic organs.
- People with weak digestion and cold constitutions: For those who frequently experience bloating, diarrhea, spleen-stomach deficiency and cold, or fear of cold, eating cold-natured seafood like squid will make their condition more serious.

Does dried squid have any different conflicts compared to fresh squid?
Many diners when searching for what dishes squid conflicts with wonder if there are any differences in dietary taboo principles between dried squid and fresh squid.
- Taboo principles still apply to dried squid: The nutritional nature and cold property of dried squid do not change compared to fresh squid. Therefore, taboos such as not eating with foods rich in vitamin C, not drinking alcohol, green tea, or eating with cold-natured foods… still apply to dried squid.
- Unique risks of dried squid: Dried squid has gone through a dehydration process, so its natural mineral content and salinity are higher than fresh squid. People with a history of high blood pressure, kidney disease, or cardiovascular disease need to pay attention to controlling their portion size to avoid sudden blood pressure spikes.
- Prioritize naturally dried squid without preservatives: To enjoy dried squid safely, you should choose dried squid products that are sun-dried or naturally dried, with a clear origin, free of chemical preservatives or industrial food coloring. Buying from reputable brands like Ola Squid will give you peace of mind regarding quality and food safety.

How to eat squid safely and properly
To prepare delicious, perfectly flavored squid dishes that are safe for the health of the whole family, immediately pocket the following notes:
- Choose fresh and delicious squid and ensure hygiene: Choose squid with crystal-clear eyes, firm bodies, heads tightly attached to the body, and skin intact with flashing neon colors. Avoid buying squid that is mushy, has cloudy eyes, or has a strange foul odor.
- Cook squid thoroughly before eating: Raw or rare seafood harbors many bacteria (such as Vibrio parahaemolyticus) and parasites. Cook them thoroughly at high temperatures to kill bacteria while still retaining their crispness and sweetness.
- Avoid eating squid prepared long ago: Cooked squid is very susceptible to protein denaturation, which is an ideal environment for bacteria to enter if left at room temperature for more than 2 hours. You should eat it immediately after preparation or store it properly in the refrigerator if you haven’t finished it.
