Your body absorbs numerous chemicals and toxins from your environment, food, medications and cosmetics as well as household chemicals such as preservatives, pesticides and fertilizers. Your body works constantly to cleanse by filtering the blood and excreting wastes and toxins through the kidneys, liver, intestines and skin. Some foods enhance the cleansing effects and facilitate body mechanisms that remove wastes from the blood. The Cleveland Clinic notes that foods with antioxidant and antitoxin properties as well as foods that contain certain vitamins and minerals cleanse the blood.
Citrus fruits, particularly lemons, which contain vitamins A, B and C as well as calcium, phosphorus, potassium and fiber, are blood-cleansing foods. Purdue University advises that drinking a few drops of the acidic lemon juice combined in warm water early in the morning helps to cleanse the blood of toxins and waste products.
High-fiber foods help to cleanse your blood of bad fats, cholesterol, toxic chemicals and other useless substances. The Mayo Clinic explains that soluble fiber in foods such as oatmeal, barley, beans, flaxseed and raw vegetables dissolve in the body, forming a gel-like substance that helps improve the removal of toxins as well as unhealthy fats and cholesterol from the blood. Insoluble fiber, found in whole wheat, wheat bran, nuts and green vegetables, pass through the digestive system without dissolving, helping to bulk up waste products to facilitate healthy digestion and excretion.
Green, Leafy Vegetables
The U.S. Department of Health and Human Services states that green, leafy vegetables such as kale, broccoli, spinach and romaine lettuce are an important part of a healthy, balanced diet. These foods and other bitter-green vegetables such as mustard greens, okra and Swiss chard are blood-cleansing foods, which are also abundant in nutrients such as vitamins A, B and C, iron and folic acid.
Pectin and Fruit
Fruit such as apples, bananas, papaya, oranges, kiwis, figs, peaches, pineapples and mangoes are rich source of vitamins A, B, C and E and minerals such as potassium. Particularly when eaten fresh and raw, fruit contains high quantities of the antioxidant compounds glutathione and lycopene, which detoxify and help remove harmful chemicals and waste products in your blood called free radicals. Apples, oranges and other fruit also contain a dietary fiber and chemical called pectin, which helps to remove excess fats from your liver and blood, as reported by a 1998 study published in "The Journal of Nutrition."
