Unified Care- Food Pairings To Boost Nutrient AbsorptionOptimal nutrient absorption -
Catechins are antioxidants, meaning they combat oxidative stress by neutralizing free radicals. Excess oxidative stress , BTW, can lead to chronic conditions including heart disease, rheumatoid arthritis, and cancer.
There's a catch, though: On their own, catechins are unstable in neutral or non-acidic environments such as our intestines, says Michelle Nguyen , R. In there all alone, catechins are prone to breaking down, leading to poor absorption overall. Enter vitamin C , an essential nutrient involved in immune function and collagen synthesis.
Vitamin C acidifies the intestinal environment, which prevents catechins from degrading, according to Kylie Ivanir , M. This optimizes their absorption in the intestines, ensuring your body can actually make use of that antioxidant goodness. Food Pairings: vitamin C-rich fruits with tea or a tea-based smoothie.
The classic combo of lemon juice plus tea is a perfect example. Not crazy about hot tea? Make a matcha green tea smoothie with strawberries or a vitamin C-packed fruit of your choice, suggests Nguyen.
Vitamin C also enhances the absorption of non-heme iron, a type of iron found in plant foods such as beans, lentils, nuts, seeds, tofu, and spinach. Iron is needed for making hormones and carrying oxygen in the blood.
However, due to its chemical structure, non-heme iron has a low bioavailability , meaning it's not easily absorbed by the intestines. FYI, the other type of iron is heme iron, which is found in animal products such as poultry, beef, seafood, and shellfish, and is more easily absorbed on its own, says Figueroa.
Pairing non-heme iron with vitamin C can boost the former's absorption, as vitamin C forms a soluble aka dissolvable bond with non-heme iron, according to an article published in the Journal of Nutrition and Metabolism. And this changes the chemical structure of non-heme iron into a form that's more easily absorbed by intestinal cells, notes Figueroa.
Food Pairings: a squeeze of lemon juice into lentil soup; bell pepper sticks with hummus ; extra tomatoes and bell peppers mixed into black bean chili. It's no secret that calcium is crucial for bone health, but simply consuming calcium isn't enough; you'll need to fuel up on vitamin D, too.
It works by transporting calcium through intestinal cells, according to a scientific review in the World Journal of Gastroenterology. In fact, without enough vitamin D, you'll only be able to absorb 10 to 15 percent of the calcium you eat, notes Figueroa.
It's worth noting that you don't necessarily need to eat vitamin D and calcium at the same exact time to optimize absorption, says Figueroa. This is because vitamin D is fat-soluble , meaning it's stored in your fatty tissue for a long time, she explains.
As a result, your body always has some vitamin D available. That said, "it's more important to focus overall intake of [foods rich in calcium and vitamin D] throughout the day," rather than at the same time, she notes.
Think of it as a wider "time frame" for pairing these nutrients. But if you're all about efficiency or just forgetful , it may help to eat 'em together. Food Pairings: calcium-rich cruciferous greens such as broccoli or turnip greens with vitamin D-rich fish such as salmon and tuna ; mushroom stir-fry with calcium-fortified tofu.
Speaking of which Since this combo is so important for bone health, it's common to find calcium-rich foods such as dairy milk and yogurt fortified with vitamin D. Some products — i. plant-based milks — are often fortified with both nutrients, which may help in terms of efficiency and convenience, explains Figueroa.
The exception is homemade nut milks, which aren't good sources of calcium, notes Figueroa. If you want both nutrients in one product, store-bought fortified versions are the best choice.
Vitamin D also increases intestinal absorption of magnesium , a mineral involved in functions such as cell repair and heart rate, explains Ivanir.
And as it turns out, the feeling is mutual: Magnesium is a cofactor for vitamin D synthesis, she says. This means magnesium needs to be present in order for the skin to make vitamin D; it's the perfect example of a two-way street.
Food Pairings: salmon or trout — which bring the vitamin D — coated with almonds instead of breadcrumbs for that dose of magnesium; salad topped with salmon and pumpkin seeds ; mushroom stir-fry topped with chopped cashews.
Sometimes improving absorption is all about slowing things down. Such is the case of carbs and protein, an important combo for satiety, energy, and post-workout recovery. This increases your blood sugar levels, which is a natural and normal response.
The problem is when your blood sugar increases too fast, causing a blood sugar spike. Over time, this can lead to insulin resistance and high blood glucose levels, boosting your risk of prediabetes and diabetes, she says.
Proteins break down at a slower rate than carbohydrates. So, eating the nutrients at the same time allows carbs to break down more slowly, "helping stabilize blood sugar levels because the carbs [release] less sugar into the bloodstream at once," says Ivanir.
This is crucial not only for sustaining satiety and energy on a daily basis but for recovering after exercise, too. Chowing down on some carbs post-workout helps with muscle recovery by kickstarting the process of replenishing your body's carbohydrate stores your body's first source of fuel.
Food Pairings: oatmeal with a side of eggs; oatmeal with protein powder; apple slices or whole-wheat toast with nut butter.
Or any of these post-workout snacks trainers and dietitians swear by. The goal here is to partner complex carbs — which are more nutrient-dense than their refined counterparts — with lean protein — which is low in saturated fat. The main compound in turmeric , curcumin has stellar antioxidant and anti-inflammatory properties, according to a scientific review in the journal Foods.
But like the catechins in tea, curcumin "is poorly absorbed when ingested on its own," says Ivanir. The reason? It's quickly metabolized and eliminated by the body, so it can be difficult to soak up all its benefits. The solution: Add black pepper to the mix. Its main compound — piperine — can actually increase the bioavailability of curcumin by about percent!!
Pancreatic exocrine insufficiency refers to the pancreas' inability to secrete digestive enzymes, ions, and water.
Intestinal mucosal damage can arise from inflammatory disorders, radiation, and infection. Typical signs of fat malabsorption include loose, bulky, clay-colored stools that tend to float in water. Patients may also experience weight loss, fatigue, and generalized weakness.
Fat-soluble vitamin deficiencies may likewise develop and present with bone loss, night blindness, bleeding, and, in rare cases, hemolytic anemia. Nutritional support is essential when managing illnesses in the hospital setting.
Sepsis, shock, malignancy, and many other critical conditions may lead to intestinal slowing, anorexia, and hypermetabolic states.
Surgical patients about to receive sedation are typically advised to fast for several hours or overnight before their procedure.
To date, evidence showing that modified hospital diets confer any mortality benefit is insufficient. They may even be too restrictive.
However, early feeding and nutritional support are not known to have better outcomes, either. Additionally, patients who forego enteric feeding for long periods are more likely to become dependent on non-enteral modalities of feeding.

Introduction The gastrointestinal tract is a highly specialized organ system primarily responsible for nutrient absorption, though it has other roles. The gastrointestinal tract's wide range of functions include the following: [1] [2] [3] [4] Nutrient absorption - This comes after the breakdown of carbohydrates, proteins, fats, vitamins, and minerals, which are essential for energy production, growth, and cellular maintenance.
Egestion of waste and toxins - The process eliminates indigestible components and harmful substances from the body. Maintenance of hormonal homeostasis - The gastrointestinal tract influences appetite, satiety, and metabolism. Providing immunity - Immune cells line the gastrointestinal mucosa to defend against pathogens and maintain a balance between tolerance and reactivity.
Influencing behavior - The gastrointestinal tract is a key player in the "gut-brain axis," influencing behavior and cognitive processes. Cellular Level The Cells of the Gastrointestinal Tract Enterocytes : These are the cells that make up most of the intestinal lining.
Development Gastrointestinal development begins during the 3rd week of life. Organ Systems Involved The gastrointestinal system interacts with every organ system. Nervous System Communication between the nervous and gastrointestinal systems is accomplished by hormonal signals and the enteric nerves.
Liver cirrhosis leading to pleural effusion [23]. Function Mouth The mouth is comprised of the lips, teeth, tongue, salivary glands, hard palate, soft palate, uvula, and oropharynx. It has two natural sphincters: Upper esophageal sphincter: comprised of the cervical esophagus, cricopharyngeus, and inferior pharyngeal constrictor [29].
Lower esophageal sphincter: comprised of the diaphragmatic crura, phrenoesophageal ligament, and intrinsic esophageal muscle fibers [30].
Cardia: the gastric segment that connects with the esophagus. It has a sphincter that prevents gastric contents from refluxing to the esophagus.
Fundus: lies inferior to the cardia and functions as residual space for gastric contents. Body: the largest portion of the stomach and the site where food mixes with gastric acid secretions.
Antrum: the inferior portion of the stomach that holds the food-acid mixture before it is moved into the small intestine. Pyrolus: the portion of the stomach connected to the duodenum. It is comprised of a thick muscular ring that acts as a sphincter controlling gastric emptying.
Of note, the stomach is the first site of absorption for lipid-soluble substances such as alcohol and aspirin. Duodenum: the segment that attaches to the stomach. It is approximately 30 cm or 1 foot long. The duodenum receives the food-acid mixture from the stomach, which then becomes chyme.
Liver, pancreas, and gallbladder secretions come into contact with chyme in this segment, preparing it for further digestion and subsequent absorption. The duodenum absorbs most of the iron, calcium, phosphorus, magnesium, copper, selenium, thiamin, riboflavin, niacin, biotin, folate, and the fat-soluble vitamins A, D, E, and K.
Intestinal villi—the small finger-like projections at the epithelial apices—increase the intestinal cells' surface area for absorption. Jejunum: measures approximately cm or 8 feet long and is the second portion of the small intestines.
The lacteals—the jejunal lymphatic vessels—aid in the absorption of lipids, which have become glycerol and free fatty acids in this segment. Amino acids are also absorbed in the jejunum, entering the bloodstream through the mesenteric capillaries. Ileum: approximately cm or 5 feet long.
It is the most distal segment of the small intestine, terminating at the ileocecal junction. The ileum absorbs bile salts and acids, ascorbic acid, folate, cobalamin, vitamin D, vitamin K, and magnesium.
Mechanism Digestion is the body's natural process of converting food into products that can be absorbed and used for nourishment. This process is unmediated and passively regulated by an electrochemical concentration gradient. Transcellular pathway: molecules first move from the intestinal lumen into the enterocyte by crossing the apical membrane.
From inside the cell, the molecules traverse the basolateral membrane and enter the extracellular space. In contrast to the paracellular pathway, transcellular transport is active, requiring energy expenditure in the form of Adenosine Triphosphate ATP.
Apical and basolateral enterocyte transporters help facilitate this process. Pathophysiology Carbohydrate Absorption Carbohydrate digestion begins in the oral cavity with the mechanical breakdown of food. Protein Absorption Chemical protein digestion begins in the stomach and continues into the jejunum.
Vitamins and Minerals Vitamins A, D, E, and K are fat-soluble. Clinical Significance Malabsorption occurs when the body cannot effectively absorb nutrients.

While there haven't yet been enough human studies to fully understand how it works, preclinical studies show a slew of promising benefits that make it worthwhile to integrate a little turmeric into your diet.
This vitamin-and-mineral combo will help keep your bones healthy. To get this pairing right, eat foods offering vitamin D, such as salmon, tuna, egg yolks or fortified foods like milk and non-dairy beverages such as soymilk and orange juice. Eat a variety of calcium-providing foods, including collard greens, broccoli, dried figs, oranges and dairy foods.
Other protein sources like nuts, legumes, grains, and vegetables are incomplete, meaning they lack one or more of the essential amino acids needed for growth and development.
But by pairing incomplete proteins together, you can create a complete protein source. I like my chili lime Buddha bowls for a balanced lunch or dinner!
Getting enough of these vitamins and maximally absorbing them is important because deficiencies are connected with heightened risk of cancer and type 2 diabetes. If possible, make the fat source a largely unsaturated one, such as nuts, seeds, avocadoolive oil or olives.

You may already be cooking your chickpeas with sources of sulfur like onions and garlic, and that's making your zinc absorption even better. Absorbing antioxidants on a vegan diet can be a bit tricky. So, to ensure you're absorbing them properly, you should cook tomatoes, that are rich in the antioxidant lycopene, with fats like olive oil, says Perez. Bone health is vital for everyone, even those who aren't vegan, and calcium is helpful for strengthening your bones.

Although the body needs very small amounts of zinc, this mineral supports many physiological processes such as immune function, says Rachel Werkheiser , M. The best sources of zinc are animal products, such as poultry and fish; the zinc in these foods is most easily absorbed by the body. Plant foods such as whole grains, legumes, and seeds also offer zinc, says Werkheiser. However, they also contain phytates, aka "antinutrient" compounds that actually bind to zinc and reduce its absorption, according to Harvard. Chan School of Public Health. Animal food not your thing? Soaking whole grains and legumes in water for eight to 12 hours before cooking also helps reduce their phytate content, says Ivanir. However, it's worth noting that zinc from other plant sources — such as mushrooms or kale — is also best absorbed with an animal protein source, as it "is able to increase the absorption of zinc" in general, which is thought to work by increasing its solubility in the intestines. Food Pairings: oatmeal and eggs; peanuts in a shrimp stir-fry; mushrooms with chicken. Pair all zinc-rich plant foods — especially phytate-containing whole grains, legumes, and seeds — with animal protein. As for animal sources of zinc, such as red meat, poultry, and shellfish? Since they're already sources of protein, you can eat them solo without thinking about having to pair zinc plus protein. The body stores vitamins A, D, E, and K in fatty tissue. These vitamins also need fat from food in order to be absorbed by the body, according to a review in the journal The Clinical Biochemist Reviews. |
