The next section discusses beetroot dosage, adverse effects, and advantages. Although there is no official suggested dose for beets, several suggestions are available. The answer to how much beetroot you should eat each day is 250,000 mg. This is more than three times the amount used in most studies! You should not use more than this every day. The American Cancer Society recommends that you eat about 350 milligrams of beta-carotene a day from foods other than supplements. This is equivalent to just under 1 cup of raw baby carrots or 2 cups of green beans. Beetroots are good for your eyes. Studies have shown that people who eat more than 75 milligrams of beta-carotene per day (the equivalent of about one large beet) are less likely to develop macular degeneration. This is the leading cause of blindness in Americans over 50 years old. Beetroots are good for your heart. Scientists at Harvard University found that people who ate more than 75 milligrams of beta-carotene daily were 30% less likely to die from cardiovascular disease. They also discovered that the more yellow vegetables you eat, the more antioxidants you get benefit from. Beets are very yellow so they contain lots of antioxidant vitamins and minerals.
