WEBVTT - Do Juice Cleanses Work?

0:00:02.040 --> 0:00:07.360
<v Speaker 1>Welcome to brain Stuff from how Stuff Works. Hey, brain stuff,

0:00:07.400 --> 0:00:11.600
<v Speaker 1>Christian Sager. Here, let's talk about purity because we are

0:00:11.640 --> 0:00:16.120
<v Speaker 1>surrounded by toxic stuff in this modern world. Car emissions

0:00:16.160 --> 0:00:20.599
<v Speaker 1>in our air, factory runoff in our water, herbicides and pesticides,

0:00:20.600 --> 0:00:24.000
<v Speaker 1>and our food trolls and our comments sections. If our

0:00:24.040 --> 0:00:28.600
<v Speaker 1>bodies are temples, every pizza role is a desecration. How

0:00:28.680 --> 0:00:33.160
<v Speaker 1>can we become pure again? Well? Juice cleanses supposedly rid

0:00:33.200 --> 0:00:37.879
<v Speaker 1>our bodies of toxins and restore our digestive systems. Depending

0:00:37.920 --> 0:00:42.159
<v Speaker 1>on the specific and sometimes copyrighted cleans you spend a

0:00:42.200 --> 0:00:45.200
<v Speaker 1>couple of days to a couple of weeks consuming nothing

0:00:45.560 --> 0:00:50.440
<v Speaker 1>but liquefied fruits, vegetables, and maybe some nut milk. Since

0:00:50.520 --> 0:00:53.519
<v Speaker 1>lots of people are pretty bad about eating enough fruits

0:00:53.520 --> 0:00:56.240
<v Speaker 1>and vegetables to begin with, this may mean that during

0:00:56.280 --> 0:00:59.440
<v Speaker 1>a juice cleanse you'd be getting more vitamins and minerals

0:00:59.440 --> 0:01:02.520
<v Speaker 1>than usual. Wool. These are substances that your body needs

0:01:02.520 --> 0:01:06.440
<v Speaker 1>to turn food into energy and to grow and maintain cells.

0:01:06.520 --> 0:01:10.360
<v Speaker 1>Some even have antioxidant properties, which means that they can

0:01:10.400 --> 0:01:15.319
<v Speaker 1>help prevent cellular damage under particular circumstances. The benefits of

0:01:15.360 --> 0:01:18.399
<v Speaker 1>these vitamins and minerals are real, but keep in mind

0:01:18.440 --> 0:01:21.240
<v Speaker 1>that your body can only process a certain amount of

0:01:21.280 --> 0:01:24.240
<v Speaker 1>them at once. After that, you're just going to excrete

0:01:24.240 --> 0:01:27.759
<v Speaker 1>the rest. Research does show that eating fruits and vegetables

0:01:27.880 --> 0:01:31.720
<v Speaker 1>rich in these substances can decrease some risk of some

0:01:31.880 --> 0:01:35.080
<v Speaker 1>diseases in the long run. The key phrase here is

0:01:35.160 --> 0:01:37.720
<v Speaker 1>in the long run. The best way to reap these

0:01:37.720 --> 0:01:42.240
<v Speaker 1>benefits is to consistently eat five or more servings every day.

0:01:42.720 --> 0:01:46.200
<v Speaker 1>One juice binge isn't gonna do much. Consuming nothing but

0:01:46.360 --> 0:01:48.920
<v Speaker 1>juice for a few days also means that you'd get

0:01:48.960 --> 0:01:53.080
<v Speaker 1>a lot less fiber, fat, and protein, and way fewer

0:01:53.120 --> 0:01:56.680
<v Speaker 1>calories than normal. Fats and proteins are just as essential

0:01:56.720 --> 0:02:00.640
<v Speaker 1>for healthy cellular function as vitamins and minerals, and fiber

0:02:00.720 --> 0:02:03.880
<v Speaker 1>in the diet is actually part of your colon's normal

0:02:03.960 --> 0:02:07.920
<v Speaker 1>cleansing system. It absorbs water and water soluble waste in

0:02:08.000 --> 0:02:12.720
<v Speaker 1>your intestines and moves everything on out. Plus fiber can

0:02:12.800 --> 0:02:15.919
<v Speaker 1>slow down your body's uptake of sugar, keeping your blood

0:02:15.919 --> 0:02:19.720
<v Speaker 1>sugar levels more stable without it, and considering the high

0:02:19.840 --> 0:02:22.520
<v Speaker 1>levels of fruit sugars and the limited calories involved in

0:02:22.560 --> 0:02:25.720
<v Speaker 1>a juice diet, you will feel extra hungry and may

0:02:25.800 --> 0:02:30.320
<v Speaker 1>experience dizzy and blood sugar spikes and crashes. A day

0:02:30.400 --> 0:02:32.480
<v Speaker 1>or two of this shouldn't do any harm to the

0:02:32.520 --> 0:02:37.000
<v Speaker 1>average person, but restricting calories and nutrients from much longer

0:02:37.040 --> 0:02:40.400
<v Speaker 1>than that can trigger starvation mode. Your body doesn't know

0:02:40.520 --> 0:02:43.320
<v Speaker 1>when it's going to get more food, so it slows

0:02:43.360 --> 0:02:47.200
<v Speaker 1>your metabolism down. When this happens too often, the change

0:02:47.320 --> 0:02:52.000
<v Speaker 1>can be permanent, so is it worth it Psychologically? Maybe

0:02:52.160 --> 0:02:55.200
<v Speaker 1>you'll probably lose a little weight to the decrease in calories,

0:02:55.280 --> 0:02:58.320
<v Speaker 1>which might be what you're looking for, and people around

0:02:58.320 --> 0:03:02.280
<v Speaker 1>the world have been using short asks to practice mindfulness

0:03:02.280 --> 0:03:07.760
<v Speaker 1>for hundreds, if not thousands of years. But physiologically, juice

0:03:07.760 --> 0:03:11.440
<v Speaker 1>cleanses don't help clear toxins out of your body. The

0:03:11.560 --> 0:03:15.360
<v Speaker 1>thing is that your liver and your kidneys are natural detoxifiers.

0:03:15.760 --> 0:03:18.760
<v Speaker 1>They filter bad stuff out of your body all the time,

0:03:19.200 --> 0:03:22.799
<v Speaker 1>but they need the full complement of nutrients provided by

0:03:22.800 --> 0:03:31.320
<v Speaker 1>a healthy diet in order to do so. Check out
