Natural nutrient sources -
Get all the nutrients you need with these foods. It's normal to turn to supplements in an attempt to supply your body with nutrients you think might be missing from your diet. However, turning to supplements without first considering the quality of your diet may not get you anywhere.
Supplements can help fill gaps , but it's always best to get most of your vitamins and minerals through a nutritious and balanced diet. Try taking a food-first approach with this guide to the top food sources for every vitamin and mineral. You'll notice that many overlap and -- who'd've known -- vegetables appear as a top source for almost every nutrient.
Vitamin A is a single vitamin, but two types are found in food. Preformed vitamin A, which your body can use immediately, is found in animal foods. Provitamin A is found in plant foods, and it's a precursor to the type of vitamin A your body can use.
Beta-carotene is the most common example of provitamin A. The B vitamins are a group of eight essential nutrients humans need to support health. They're all lumped into one class of vitamins because they have similar properties and are found in many of the same foods.
Best known for supporting immune health, vitamin C also contributes to the growth, development and repair of various tissues in your body. Vitamin C is an important part of the structure of your skin, tendons, ligaments and blood vessels, and it helps to form scar tissue in response to injuries.
To make sure you're getting enough vitamin C in your diet, eat plenty of these vitamin C-rich foods:. The very best source of vitamin D is sunshine, but plenty of foods contain trace amounts of vitamin D to support a well-rounded diet.
It's hard to get enough vitamin D from food alone, so it's a good idea to get outside for a few minutes each day in addition to prioritizing these foods. Vitamin E is an antioxidant responsible for many bodily functions, including the formation of red blood cells.
Deficiency in vitamin E can lead to complications such as nerve damage, muscle weakness, loss of motor control, weakened immune function and vision problems.
Vitamin K is primarily a coagulant, which means it helps blood clot. Without vitamin K, you would lose too much blood even from a small cut or scrape. People on blood-thinning medications should talk to their doctor about vitamin K before increasing their consumption.
If it's safe for you to eat more vitamin K-containing foods, try adding these sources to your diet:. In addition to vitamins, the human body requires several minerals to function optimally. Mineral deficiencies are often responsible for symptoms like fatigue, poor sleep, low moods and lack of focus.
You need two types of minerals to support your health: macrominerals, which you need in large amounts, and trace minerals, which you need in smaller quantities.
The macrominerals include calcium, phosphorus, magnesium, sodium, potassium, chloride and sulfur. Trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride and selenium.
Calcium is the most abundant mineral in the human body -- you need plenty of it to keep your bones and teeth healthy, as well as support muscle and nerve function.
The best sources of calcium include:. Phosphorus helps form your bones and teeth, makes protein for tissue growth and repair, and produces the molecules your cells use for energy.
These foods contain ample phosphorus:. Many plant foods contain phosphorus, but most plants store the mineral as phytic acid, which humans can't digest or absorb. The best way to get phosphorus is from animal foods.
Like the other macrominerals, magnesium supports nerve and muscle function, as well as bone and heart health.
You can find magnesium in:. This electrolyte is essential for maintaining fluid balance in your body and helping your muscles contract, among other things. Many people try to limit their sodium intake and some people need to , but consuming too little sodium can lead to health problems just like consuming too much can.
The foods highest in sodium generally aren't the healthiest sources of sodium, and sometimes a single savory snack can nearly reach the daily recommended sodium limit. However, some whole foods contain trace amounts of sodium, including:.
You likely already eat plenty of foods high in sodium, such as bread, pasta, soup, deli meat, sauces and dressings, broths, stocks, canned foods, frozen foods and snack foods.
Most people don't need to increase their sodium intake and should limit sodium-rich foods if they tend to eat more than the recommended daily allowance of 2, milligrams. Another important electrolyte, potassium supports a regular and healthy heartbeat, offsets sodium's effect on blood pressure, supports nerve function and muscle contraction, and moves waste products out of cells.
Foods high in potassium include:. This cereal grain thrives in a warm , humid climate with heavy rainfall or wet ground. It is often grown in flooded fields called rice paddies.
Hominy grits , corn bread, popcorn, and tortillas are all made with corn. Outside the United States, this grain is called maize. Although native to the Americas, maize is now cultivated throughout most of the world and is a staple food in many areas. It grows in various soils and climates and at different elevations.
Corn is also used to produce sweeteners, such as corn syrup and cornstarch. Sorghum and millet are other grains commonly used as livestock feeds.
These grains are also staple foods for people in parts of Africa and Asia, where they are used in breads, porridges , and cakes. Three other grains—barley, oats, and rye—are important in many regions. Barley thrives in a wide range of climates.
One type of barley is the source of malt for making beer. Barley is also used in making vinegar , malt extract, and beverages similar to milk. Pearl barley, the most popular form of this grain, is often used in soups and other foods. Oats and rye were domesticated much later than other grains.
Oats are used mainly as livestock feed, but also go into oatmeal and other breakfast cereals. After wheat, rye is the second most common grain used as a bread flour; the two are often mixed together in breads.
Bread made with rye alone, called black bread , is popular in many European countries. To a botanist , it means the part of a plant that contains seeds. According to this definition, fruits include most nuts, as well as vegetables, such as cucumbers and tomatoes.
A perennial is a plant that lives for more than one growing season. Fresh fruits are rich in carbohydrates, vitamins, minerals, and fiber. They can be preserved by freezing, canning, or drying. Different fruits grow in different climates, and may not grow well in climates that are too cold, hot, dry, or wet.
Based on the kind of climate in which they grow, fruits can be classified in different groups: temperate fruits, subtropical fruits, and tropical fruits. Temperate fruits grow best where there is a well-defined cold season, as in the U. states of Washington and Oregon. Temperate fruits include apples, berries, grapes, pears, plums, and peaches.
Subtropical fruits thrive where temperatures are mostly warm year-round. The area around the Mediterranean Sea has a subtropical climate.
Citrus fruits, such as lemons, oranges, grapefruits, dates, pomegranates, and some types of avocadoes, are subtropical fruits.
Tropical fruits require a hot climate to grow. Tropical fruits, such as bananas, mangoes, and papayas, grow in hot, humid areas like the Philippines.
Vegetables are the edible parts of herbaceous plants. Herbaceous plants, sometimes just called herbs, have stems that are softer and less woody than those of trees and sh rubs.
Vegetables are good sources of fiber, minerals, and vitamins. Most vegetables are annuals , living for only one growing season. Vegetables can be roots , leaves, stems, seeds, or bulbs.
For example, carrots, radishes, and beets are roots. Cabbage, celery, lettuce, and spinach are leaves or leafstalks. Heads of broccoli are flower stalks topped by thick clusters of flower buds. Asparagus is a stem. Cucumbers, eggplants, and tomatoes contain the seeds of the plant.
Garlic, leeks, and onions are bulbs. Some plants, called tubers , have a special type of underground stem that can be eaten fresh as a vegetable or used as an ingredient in other dishes. In temperate regions, the most important tuber is the potato.
The potato was first a food staple to indigenous cultures of the Andes of South America. Today, major potato-growing countries include Russia, China, and Poland. Important tropical tubers include yams, cassavas , and taros. These tubers are staple foods in many cultures.
For instance, taro is a major food crop of the islands of Polynesia, as well as West Africa. Cassava is a staple food for more than million people in Africa and Latin America.
Legumes, Meat, Poultry, Fish, and Eggs Legumes are plants that are raised for their edible seeds or seed pods. Peas, lima beans, soybeans, peanuts, and lentils are all legumes. Legumes that are harvested for their dry seeds, such as beans or lentils, are called pulses.
Pulses are food staples in India and Pakistan. Legumes and pulses contain high amounts of protein. In addition, they supply iron, other minerals, and vitamins. Meat is a high-protein food and is rich in other nutrients, as well. Beef can come from cows , bulls , or steers.
Cows are adult female cattle. Bulls are adult male cattle capable of reproduction. Steers are adult male cattle that have been castrated , or been made incapable of reproduction. Meat from very young cattle, or calves, is called veal. Meat from hogs is called pork.
Lamb is meat from sheep less than a year old. It is especially popular in the Middle East, Australia, and the United Kingdom. Mutton , meat from mature sheep, has a stronger flavor and a rougher texture than lamb.
Bison , water buffalo, camels, goats, and yaks are all sources of meat. Wild animals, such as rabbits and deer, are also eaten as meat. Meat from wild animals is called game. Raising chickens is a major industry in many countries, including China, the United States, Russia, and across the European Union.
Ducks, turkeys, geese, and guinea fowl are also raised for food in many parts of the world. Fish and shellfish are probably the most popular meats worldwide.
Fish and shellfish are excellent sources of vitamins and minerals. People eat fish raw or cooked, and preserve it by canning, freezing, drying, salting, smoking, or pickling. Most of the fish and shellfish people eat come from the ocean. Tuna is one of the most popular ocean fish.
Other fish come from inland bodies of fresh water, such as lakes and rivers. Bass, perch, and carp are popular freshwater fish worldwide. An increasing amount of fish comes from fish farms, where fish and shellfish are raised commercially. The cultivation of fish and shellfish is called aquaculture.
Clams, oysters, crabs, and shrimp are popular types of shellfish. Abalone, a kind of mollusk , is another type of seafood. Conch , a large type of sea snail, is eaten in the Florida Keys and in the West Indies.
Eels, octopuses, squids, and mussels are other popular seafoods. Eggs are a source of proteins, fats, minerals, and vitamins. Boiled, fried, scrambled, or deviled, chicken eggs are popular around the world. They are also used in a variety of baked goods.
People also eat the eggs of other birds, such as ducks and quail, and those of reptiles , such as turtles and crocodiles. The eggs of certain fish, mainly sturgeon , are prepared as a delicacy known as caviar.
However, goats, camels, reindeer, sheep, yaks, and water buffalo supply milk products as well. Soy milk is made from soaking and grinding soybeans with water.
Milk and dairy products supply proteins, carbohydrates, fats, and essential vitamins and minerals. The Maasai people of East Africa use milk as a staple food, and it constitutes a huge part of their diet.
Yogurt, a fermented milk product, is a staple food in parts of the Middle East and India. Diets can also vary within a single country. Geographic differences explain part of this variation. For example, people who live near the ocean might eat greater amounts of fish than people who live farther inland.
People living in cool regions with short growing seasons depend on crops that mature quickly, such as potatoes. In warm, wet lowlands where the soil retains water, rice is often a staple.
Geographic factors are less important today than they were a century ago. Improved methods of agriculture and transportation , as well as increased trade and tourism , have made more types of food available to a wider variety of people. Improved methods of food processing , preservation, storage , and shipping allow many people to enjoy foods produced far from their homes.
Spanish olive oil , French cheeses, and sardines from Norway, for example, are eaten as far away as Australia. Local traditions and customs play a role in determining what foods people eat and how they are prepared.
English tradition encourages roast beef and Yorkshire pudding , a type of bread, be eaten together. Many Asians serve rice with almost every meal.
Economic factors also affect what people eat. In the U. state of Maine, lobster is usually a relatively inexpensive food. However, lobster is a luxury item in the Midwest, where it must be flown in. Lobster dishes served in Iowa may cost two to three times what they do in Maine.
In developed countries, many people have enough money to buy a variety of nutritious foods. Malnutrition is not a large problem, and people have a long lifespan. But even in these countries, there are many people who cannot buy these foods because resources are not evenly distributed throughout the population.
Even those who can afford healthy food may eat poorly. The diets of many people in developed countries are too high in the fats, salt, and refined sugars found in junk food. These diets are too low in fruits, vegetables, and fiber. In developing countries, malnutrition is more common.
A poor harvest, flood, or drought may cause famine , because the community or nation is not economically able to import food.
The diets of the urban and rural populations of developing countries are often quite different. People in urban areas eat more processed foods, while people who live in rural areas may have access to fresh milk, fruits, and vegetables.
However, people living in rural areas are the first to be affected by a poor harvest. Food and Culture People do not eat only to obtain nutrients and ward off hunger and starvation. Rituals around preparing, sharing, and consuming food serve social roles as well as biological ones.
Religion sometimes plays a role in what, and when, people eat. Followers of the Jain religion, for example, strongly believe in nonviolence toward all living things.
Strict Jains never eat meat. Many Jains also refrain from eating potatoes and other tubers because many small organisms are harmed as the tubers are pulled from the earth. Jewish kashrut law and Muslim dhabihah law outline many rules for eating. Both include a ban on pork.
Food that is prepared according to kashrut law is called kosher , while food that is prepared according to dhabihah law is called halal. During the month of Ramadan , Muslims fast, or avoid eating, during daylight hours.
Typically, Muslims will eat one meal before dawn and one after sunset, but nothing at all while the sun is shining. Ramadan is considered a time for inner reflection, devotion to God, and self-control.
Feasting is also an important ritual, both for religious and nonreligious reasons. Most religious fasting periods, such as Ramadan, are followed by holiday feasts. Eid al-Fitr is the Islamic holiday following Ramadan. One of the ways Muslims celebrate Eid is to donate food to the poor. Nonreligious holidays often include feasts as well.
In the United States, people gather to eat turkey, stuffing, cranberry sauce, and pumpkin pie on Thanksgiving. In China, families celebrate the Chinese New Year with foods that symbolize luck and prosperity, such as long noodles, chickens, fish, oysters, dumplings, tangerines, oranges, and sticky rice cakes.
Many people make dietary choices based on ethics —beliefs about what is right and wrong. For instance, some people choose not to eat meat out of concern for the environment. Vegetarians avoid eating all meat and fish.
Vegans avoid all animal products, including eggs, milk, cheese, and honey. Some people who are not vegetarians may raise or buy humanely produced animal products such as free-range chicken and grass-fed beef. Other ethics-based food practices include choosing organic or locally grown foods.
People who choose organic foods may do so because of the reduced number of chemicals in the food. Organic food relies little on genetic modification or pesticides. Organic food also releases fewer chemicals into the environment in the form of runoff.
There are fewer transportation costs, such as greenhouse gas emissions, with local foods. The way we serve and eat food is as culturally important as what foods we consume.
In East Asian countries, most people use chopsticks to pick up their food. In Europe and the Americas, a variety of utensils serve different purposes. A full, formal place setting can include a salad fork, dinner fork, dessert fork, teaspoon, soup spoon, butter knife, and dinner knife. In other countries, such as India and Ethiopia, many foods are picked up with pieces of flat bread rather than utensils.
Table manners vary widely from culture to culture. Manners include rules about how and where people should sit, when to begin eating, which utensils to use in certain situations and with which hand, and what behaviors might be considered rude.
In East Asian countries, it is considered rude to point at people with your chopsticks, or to rest your chopsticks standing upright in your rice. In Malaysia, eating with your left hand is considered unclean. In Japan, it is acceptable and even encouraged to make slurping noises while eating hot noodles, but not while eating soup.
In Russia, it is considered polite to leave a bit of food after eating, but in Brazil, people are expected to eat everything on their plates.
Cuisine can be national, such as the fresh fish and noodles associated with Japanese food.

Vegetarian diets that do not include fish may be low in two types of omega-3 fatty acids called DHA and EPA. Some evidence suggests that taking in EPA and DHA omega-3 fatty acids may lower the risk for heart disease. Also, these two omega-3s may be important during pregnancy for fetal development.
Research on other health effects of EPA and DHA varies. Vegetarians who do not eat fish or include sources of omega-3 fatty acids in their diet may consider adding fortified products to their diet. Iron is important to red blood cells. Dried beans and peas, lentils, enriched cereals, whole-grain products, dark leafy green vegetables, and dried fruit are sources of iron.
But the body doesn't absorb iron from plant sources as easily as animal sources. So the recommended intake of iron for vegetarians is almost double that recommended for nonvegetarians.
To help your body absorb iron from plants, eat foods rich in vitamin C at the same time as you're eating iron-containing foods. Vitamin C-rich foods include peppers, strawberries, citrus fruits, tomatoes, cabbage and broccoli.
Like iron, zinc is not as easily absorbed from plant sources as it is from animal products. Fish, including crab and shrimp, are sources of zinc for pescatarians. Cheese and yogurt are sources of zinc if you eat dairy products. Plant sources include whole grains, soy products, lentils, beans, nuts and wheat germ.
Zinc helps the body make proteins and grow cells. Research on zinc in the diet has found that it supports the immune system and vision, specifically. Thyroid hormones are made partly of iodine. Thyroid hormones help control the body's metabolism and play an important role in muscle growth.
Iodine can easily be added to food by using iodized salt. Seafood and dairy also are sources of iodine. People who do not eat seafood or dairy may be at risk of iodine deficiency if they do not use iodized salt.
Iodine deficiency can lead to the thyroid getting bigger as it tries to meet the body's need for thyroid hormones. When that happens to the thyroid it's called goiter. Seaweed is vegetarian option for dietary iodine. One way to start on a vegetarian diet is to slowly reduce the meat in your diet.
At the same time, increase the amount of fruits and vegetables in your diet. Here are a few tips to help you get started:.
