Vitamin A plays an essential role in converting light to electrical signals. As per research, Vitamin A is very helpful in preventing night blindness. As per another study, a Sufficient intake of Vitamin A can help prevent a rapid decline of eyesight during old age.
Promotes Heart Health
Red leaf lettuce is rich in magnesium and potassium. Therefore, red leaf lettuce is essential for maintaining a healthy heart. As per research, potassium and magnesium help keep a healthy heartbeat. A healthy heartbeat helps in easy contraction and relaxation of the heart’s muscles. The same has been backed by other research as well. However, certain heart conditions arise due to insufficient intake of Potassium and magnesium. Various studies include high blood pressure, coronary heart disease, and even heart failure in extreme cases.
Helps prevents Cancer
Red leaf lettuce can also help in preventing cancer. Antioxidants are essential to protect the body from cancer-related free radicals. As per a study, an excessive amount of free radicals are harmful to your body and lead to various diseases. Red leaf lettuce is a rich source of beta carotene, an antioxidant. In addition, vitamin C is a powerful antioxidant in reasonable amounts in red leaf lettuce. As per a controlled study, Vitamin C is helpful in the prevention of invasive cervical cancer in women.
It helps in Lowering Blood Pressure.
High Blood Pressure is a widespread medical condition. Eating sufficient quantities of red leaf lettuce is an excellent way to counter this problem. As per a recent study, Potassium-rich diets can help control blood pressure and keep it at manageable levels. As per research, Potassium helps reduce the effect of Sodium in the blood and helps dilate the blood vessels, which reduces blood pressure. Another study has backed the claim that eating an adequate amount of red leaf lettuce can help control blood pressure levels.
Helpful in Weight Loss
Red leaf lettuce can benefit your weight loss journey for various reasons. For starters, red leaf lettuce is low in calories. A low-calorie food reduces calorie intake and, in turn, results in weight reduction. At the same time, the fibre content in red leaf lettuce is high. As per a study, fibre helps the body feel full, which reduces calorie intake. Also, lettuce is high in water content. Research has shown that increased water content in food can be beneficial in losing weight.
Enhances Bone Health
Red leaf lettuce can help in enhancing your bone health. A study found that people who have a Vitamin A rich diet have stronger bones than people who don’t. In addition, the study showed that individuals with higher vitamin A nutrients had a 6% lesser chance of fractures. However, nutrients (most importantly vitamin D) other than vitamin A also play a crucial role in maintaining overall bone health.
Red leaf lettuce also has sizeable quantities of vitamin B6. As per a study, vitamin B6 promotes haemoglobin production, which helps treat anaemia. Vitamin B6 can improve anaemia even if your body is unresponsive to iron. A study conducted on 56 pregnant women (who were unresponsive to iron) showed that as little as 75 mg of vitamin B6 significantly reduced symptoms of anaemia.
Promotes Reproductive Health
A few animal studies have shown that Vitamin A (present in large quantities in lettuce) is essential for maintaining reproductive health. A rat study showed that the deficiency of Vitamin A caused infertility in male rats. As per another study, females with insufficient Vitamin A intake showed poor quality in eggs produced. However, excessive red leaf lettuce can be a problem in pregnancy. As per a study, extreme Vitamin A can cause genetic disabilities in newborn babies.
Though red leaf lettuce is safe for most people, there is a precaution worth taking. Before eating, make sure that you wash the lettuce thoroughly multiple times. Washing is necessary because lettuce attracts pests. As a result, red leaf lettuce is treated with high amounts of pesticides to protect it on the farm.
