Coconut Milk Side Effects
Coconut is a nutritious source of fiber and essential vitamins. The fruit provides coconut milk, oil, juice, water and flesh, which can be eaten fresh or dried. Although it provides a number of health benefits, coconut oil has high amount of saturated fat, which can lead to high cholesterol or weight gain. In rare instances, consuming coconut may cause an allergic reaction.
Consuming excessive amounts of coconut meat, oil or milk may lead to weight gain. Coconut flesh has 187 calories per ounce, while coconut milk has 445 calories per cup. High amounts of saturated fat in coconut may also contribute to weight gain. To avoid eating too much fat, limit your daily intake to 25 to 35 percent of your caloric intake.
People who suffer from food allergies, especially tree nut allergies, should consume coconut with caution. Coconut is considered a tree nut by the U.S. Food and Drug Administration. Manufactured foods that contain coconut generally carry a warning that the product contains tree nuts. Most people who are allergic to coconut react to the proteins in the fruit, not the oil. Coconut oil allergies are rare, but may be life-threatening.
High cholesterol levels can cause blockage in your arteries, which leads to cardiovascular issues. Coronary artery disease is caused by a blockage or narrowing of coronary arteries that pump blood to your heart. Limit your intake of foods that contain coconut oil if you suffer from high cholesterol or are at risk of cardiovascular disease. Avoid processed or fried foods that contain high amounts of coconut oil or excessive consumption of coconut meat or milk.
