The grain is carried up from the tank by an elevator and shoots out of a side pipe, or unloader, into the grain cart. The residue exits the back of the machine to either be spread across a wide area or baled as straw to use for animal bedding. Most machines use a straw chopper to make it smaller and more manageable.

However, the CDC's determination leaves some questions unanswered—including whether mixing Moderna and Pfizer vaccines could trigger additional side effects or alter the vaccines' efficacy.
Researchers are only just beginning to formally investigate the impact of combining vaccines, yet many are hopeful that this practice may not only be safe, but could heighten a person's immune response. This week, a team in the U. However, experts caution that, until there is a solid body of conclusive data on vaccine-mixing, it's important to abide by current recommendations.
The purpose of doing that will be to make sure that this combination is safe and the benefits they bring far outweigh the potential safety concerns," explained Bali Pulendran , PhD, an immunologist at Stanford. So, if two doses of the same vaccine are available to you, the CDC still says that you should make "every effort" to complete your vaccine series with a single brand. However, as Fauci will tell you, it's OK to combine Moderna and Pfizer doses if the choice is between a different mRNA shot and no second shot at all, or getting your second shot outside the recommended timeframe.

Proponents of food-combining diets believe that these principles are essential to proper health and digestion. It is also believed that the improper combination of foods leads to negative health consequences such as digestive distress, the production of toxins and disease.
Food combining refers to a way of eating in which certain types of foods are not eaten together. Proponents of food-combining diets believe improper combinations lead to disease and digestive distress.
So far, only one study has examined the principles of food combining. It tested whether a diet based on food combining had an effect on weight loss. Participants were split into two groups and given either a balanced diet or a diet based on the principles of food combining. After six weeks, participants in both groups had lost an average of about 13—18 lbs 6—8 kg , but the food-combining diet offered no benefit over the balanced diet 1.
In fact, there is no evidence to support most of the supposedly scientific principles of food combining. Many of the original food-combining diets were developed more than years ago, when much less was known about human nutrition and digestion. But what is now known about basic biochemistry and nutritional science directly contradicts most of the principles of food combining.
The rules of food combining are largely based on the idea that the body is not equipped to digest mixed meals. However, this is simply not the case. The human body evolved on a diet of whole foods, which almost always contain some combination of carbs, protein and fat. For example, vegetables and grains are typically considered to be carb-containing foods.
But they all also contain several grams of protein per serving. And meat is considered to be a protein food, but even lean meat contains some fat. Therefore — because many foods contain a combination of carbs, fat and protein — your digestive tract is always prepared to digest a mixed meal. When food enters your stomach, gastric acid is released. The enzymes pepsin and lipase are also released, which help start protein and fat digestion.
Evidence shows that pepsin and lipase are released even if there is no protein or fat present in your food 2 , 3. Next, food moves into the small intestine. There, the gastric acid from the stomach is neutralized and the intestine is flooded with enzymes that work to break down proteins, fats and carbs 3 , 4 , 5. Another theory behind food combining is that eating the wrong foods together can hinder digestion by creating the wrong pH for certain enzymes to function.
First, a quick refresher on pH. The scale ranges from 0—14, where 0 is the most acidic, 7 is neutral and 14 is the most alkaline. It is true that enzymes need a specific pH range in order to function properly and that not all enzymes in the digestive tract require the same pH. However, eating foods that are more alkaline or acidic does not significantly change the pH of your digestive tract.
Your body has several ways of keeping the pH of each part of your digestive tract in the correct range. For example, the stomach is usually very acidic with a low pH of 1—2. However, more gastric acid is quickly released until the pH is brought back down again 6. It is important to maintain this low pH because it helps start the digestion of proteins and activates the enzymes produced in the stomach. It also helps kill any bacteria in your food.
Your small intestine adds bicarbonate to the mix as soon as the contents of your stomach enter it. If you eat a very acidic or alkaline meal, your body will simply add more or less digestive juices in order to achieve the necessary pH level. Lastly, one of the most common claimed effects of improper food combining is that food ferments or putrefies in the stomach.
Supposedly, when a fast-digesting food is combined with a slow-digesting food, the fast-digesting food stays in the stomach so long that it begins to ferment. Fermentation and rotting occur when microorganisms start to digest your food. But, as mentioned earlier, the stomach maintains such an acidic pH that your food is essentially sterilized and almost no bacteria can survive 2. However, there is one place in your digestive tract where bacteria thrive and fermentation does occur.
This is in your large intestine, also known as your colon, where trillions of beneficial bacteria live 8. The bacteria in your large intestine ferment any undigested carbs, such as fiber, that were not broken down in your small intestine. They release gas and beneficial short-chain fatty acids as waste products 8. In this case, fermentation is actually a good thing. The fatty acids the bacteria produce have been linked to health benefits such as reduced inflammation, improved blood sugar control and a lower risk of colon cancer 9 ,
