You know that eating a whole box of cookies is not good for you – but experts say that overconsumption of some nutritious and healthy foods can be just as dangerous. Certainly it does not mean that you have to exclude them from your diet, but to stay health, you need to avoid consuming excessive amounts. Why?
Oranges and tomatoes
The increase in acid consumption associated with eating too many oranges or tomatoes can cause reflux. Over a long period, this can cause Barrett’s esophagus, an anomaly consisting of the formation of precancerous lesions of the esophageal mucosa. Dr. Gina Sam suggests eating only two servings of oranges or tomatoes per day and avoiding these foods if you have symptoms of reflux.
This easy to prepare fish and low in calories is popular for preparing healthy salads and sandwiches. However, eating it excessively can result in dangerous levels of mercury because mercury has higher levels than in many other fish. Excessive consumption of mercury can lead to vision problems, impaired hearing or speech, lack of coordination and muscle weakness. “Make sure you do not eat more than five cans of tuna a week, says Gina Sam, and try to replace tuna with foods with lesser presence of mercury, such as shrimp or wild salmon.”
“If hydration is the key to good health, excessive water intake can cause poisoning,” teaches Dr. Alan R. Gaby, nutritionist. This happens when excessive consumption of delutes sodium in your body, resulting in abnormally low sodium levels in the blood, which can cause brain function disorders and even death. How much water you need to drink in order not to get there? This is usually a problem facing marathoners and those who force themselves to drink a lot. But to be sure that you do not consume too much water, check your urine: if they are always transparent, reduce your water consumption.
Tofu lovers, listen up! If soy can help control cholesterol levels and blood pressure, it also prevents the absorption of iron, says Dr. Gaby. Excessive consumption may therefore cause anemia due to iron deficiency. Moreover, soybean contains pseudo-estrogenic compounds (isoflavones) whose consumption in large quantities and in the long term can cause hyperplasia of the endometrium, a proliferation of endometrial glands, which may lead to cervical cancer. If you did not know how much soy is safe, it is advisable to stick to two servings per day maximum.
This delicious leafy green vegetable is rich in nutrients: it is an excellent source of protein, fiber and various vitamins and minerals. Spinach is also rich in lutein, a carotenoid that would prevent macular degeneration caused by aging process (a common cause of vision loss and blindness), according to Alan R. Gaby. However, spinach is also rich in oxalate, a compound that can lead to the formation of kidney stones. Patients suffering from kidney stones should moderate their consumption of spinach.
This crunchy snack is an excellent source of protein, fiber, essential fatty acids and selenium. In addition, it has been proven that Brazil nuts lower cholesterol and blood pressure. However, you should not eat them every day because they are extremely rich in selenium, a nutrient that can be toxic in large quantities, warns Dr. Gaby. Eating too much Brazil nuts can cause hair loss, weakening of the nails, dermatitis, neurological abnormalities and, in severe cases, death. Dr. Joel Fuhrman, general practitioner and nutrition researcher, says that you should not consume more than 10 per day.
Reduce intake of animal protein
If you rely primarily on meats poor in fats, such as chicken or the egg whites to get your daily dose of protein, it may be time to change the regime. Dr. Fuhrman explains that consume too much animal protein can be dangerous because it pushes your body to produce the insulin like hormone growth factor 1, which causes aging and increases the risk of cancer (particularly breast cancer) when present in large quantities.
Is there any simple solution? Try to get most of the needed protein from plants and vegetables such as beans, nuts, seeds and whole grains, say Joel Fuhrman.
