Experts advise that there are two parts of the cow that we should avoid eating due to the potential presence of harmful substances that can negatively impact our health.

Beef is one of the most nutritious foods, widely chosen by many home cooks to prepare a variety of delicious dishes for family meals. In many countries worldwide, this meat is even referred to as the "king of meats" because it contains high-quality proteins, vitamins, and essential minerals such as B12, zinc, iron, and taurine. However, not all parts of the cow provide benefits for our health. Among them, experts recommend limiting the consumption of the following:

1. Beef Lungs
   Beef lungs are considered to accumulate harmful toxins, posing a danger to human health when consumed. This is because the lungs are the main respiratory organs of the cow, tasked with filtering air. As a result, they easily accumulate dirt and bacteria. Moreover, the lungs contain several cavities where dust and other debris can collect. Eating this part of the cow may inadvertently introduce heavy metals into the body, negatively affecting health.

2. Beef Liver
   Beef liver is one of the most nutrient-rich parts of the cow and is commonly used as an ingredient in various delicious dishes in many countries. However, few people are aware that it contains a significant amount of cholesterol and heavy metals that can have detrimental effects on health if not properly prepared or consumed in excessive amounts. Therefore, it is advisable to consume beef liver in moderation to avoid excess cholesterol, toxins, and heavy metals that may harm health.

Common Mistakes When Eating Beef:

• Eating Beef at Night: Many people choose beef for dinner to help control body weight more effectively. However, the high iron content in beef can cause the liver to work at full capacity at night, which is typically a time when the liver "needs" rest. This can lead to the liver's biological clock being disrupted, resulting in abnormal blood sugar levels. If this occurs frequently, the body may face risks such as diabetes and various chronic diseases.

• Eating Rare Beef: Although rare beef has a delicious, fresh taste, it should not be consumed too often. This is because consuming undercooked beef increases the risk of parasites or worms entering the body due to poor hygiene in farming, slaughtering, and transportation processes. It is essential to eat properly cooked beef and ensure its source is reliable.

• Having Open Wounds: Beef is not ideal for the healing process of wounds. While its nutrients are beneficial to health, it can cause wounds to darken and increase the likelihood of scarring.

• Treating Pigmentation or Freckles: If you are treating pigmentation and freckles, consuming beef can worsen the condition, causing it to spread faster.

• Eating Beef with Seafood: Combining beef with seafood creates a precipitate of salt. This type of salt not only hinders the absorption of phosphorus but also slows down calcium absorption.

• Drinking Tea After Eating Beef: Tea contains tannins, which, when combined with the protein in beef, block the absorption of essential minerals like iron, zinc, and magnesium. It can also cause the intestinal lining to constrict, reducing bowel movement and leading to constipation.
