7 Foods That Can Be Poisonous If Eaten Incorrectly

While delicacies are delicious, they are not necessarily healthy. Although healthy foods are nutritious, they are not harmless in large quantities. Healthy foods like nuts, fish, leafy greens, or whole grains should not be overeaten, otherwise, they become the opposite of healthy. For any food, moderation is key to enjoying its benefits.

Spinach

Spinach is a nutrient-rich vegetable, known as the "king of vegetables." It contains a large amount of beta-carotene and is an excellent source of folic acid, iron, potassium, and magnesium. Because of its high iron content, many people consider it a great food for replenishing blood. However, eating too much spinach not only fails to supplement iron but may also have adverse effects.

Spinach in Broth

The human body's absorption and utilization of ingested iron does not depend on the iron content in the food, but on its chemical form. Only iron that is dissolved in the intestines can be absorbed and utilized by the body. The iron in spinach is not easily absorbed by the small intestine; most of it easily combines with oxalic acid to form precipitates, which can affect kidney health.

Furthermore, spinach can interfere with the absorption of zinc and also affect calcium absorption. Therefore, pregnant women and children should not eat too much of it.

Beetroot

Beetroot is rich in potassium, phosphorus, and easily digestible sugars, and it can supplement the body with various amino acids. Additionally, it has multiple effects such as promoting gastrointestinal peristalsis, aiding digestion, eliminating toxins from the body, expelling waste, promoting fat metabolism, and lowering blood pressure.

However, beetroot contains a large amount of sugar, so diabetics should consume it with caution. Also, beetroot contains a significant amount of dietary nitrates. If it is cooked and left for too long, or pickled for an extended period, the nitrates can be reduced to nitrites. Consuming excessive amounts can lead to poisoning. When digestive function is impaired or stomach acid is too low, even fresh beetroot can cause poisoning and lead to intestinal cyanosis.

Tuna and Beetroot Salad

Red Meat

Red meat generally refers to meat that is red before cooking, such as pork, beef, and mutton. Red meat is rich in minerals, especially iron and zinc, which are easily absorbed and utilized by the body. It is also a good source of protein, vitamins B1, B2, A, and D. It can be eaten in moderation, but excessive consumption is not good for health.

Spiced Braised Beef

Compared to white meat, red meat contains more fat, and a higher proportion of saturated fatty acids, which is not conducive to preventing cardiovascular diseases, being overweight, or obesity. People who eat a lot of red meat have a higher risk of certain diseases, so its intake should be reduced.

Oysters

Oysters are the richest source of zinc among all foods. Every 100g of oyster, excluding the shell, contains 87.1% water and 71.22mg of zinc, making it an excellent food for zinc supplementation. In addition, it has other benefits such as purifying blood stasis, strengthening the liver and detoxifying, and enhancing sexual function.

It should be noted that oysters are a type of shellfish that is easily contaminated by toxins. Eating too many can easily lead to illness or poisoning in humans. Furthermore, consuming too many oysters can increase acidic and purine substances in the body, making one more susceptible to gout and kidney disease. It is especially not advisable to eat them with beer.

Oat and Brown Rice Porridge

Brown Rice

Brown rice is a synonym for healthy food. Eating brown rice is particularly beneficial for diabetics and the obese. Because its carbohydrates are wrapped in coarse fiber, the body digests and absorbs them more slowly, which helps control blood sugar well. At the same time, the trace elements in brown rice help improve insulin sensitivity, which is very helpful for people with impaired glucose tolerance.

Although brown rice is good, nutrition experts do not recommend eating too much of it. Because brown rice contains inorganic arsenic, a semi-metallic element that is harmful and has no benefits to the human body and is a carcinogen. The "safety standard" set by the World Health Organization is: a person weighing 60 kg should not consume more than 0.12 mg per day (equivalent to eating about half a jin of brown rice a day).

Brown rice can also be eaten in moderation. As long as it is not eaten as a staple food, occasional consumption is not a problem.
