Fruits and vegetables
Fruits and vegetables are an important part of a healthy diet, and including a variety of them in your meals and snacks is a smart choice. They’re naturally low in calories and fat, and high in vitamins, minerals, and fiber.
The best way to get the nutrients your body needs is to eat a variety of fruits and vegetables every day. The 2015-2020 Dietary Guidelines for Americans recommend that adults eat at least 1 1/2 to 2 cups of fruit and 2 to 3 cups of vegetables a day. And they should focus on eating more nutrient-dense foods—those that have a lot of vitamins, minerals, and fiber but are lower in calories.
Below are some specific recommendations for fruit and vegetable intake from the Dietary Guidelines for Americans. Note that the recommendations are different for men and women, as well as for different age groups.
The amounts below represent what experts consider adequate nutrition for most people. Individual needs vary depending on age, gender, activity level, pregnancy status, health conditions, and other factors.
Whole grains are an important part of a healthy diet. They contain fiber, vitamins, and minerals that are essential for good health. Whole grains include bread, cereal, rice, and pasta.
Most Americans don’t eat enough whole grains. The 2015-2020 Dietary Guidelines for Americans recommend that adults eat at least half of their grains as whole grains. This means eating at least 3 ounces (⅔ cup) of whole-grain foods every day.
Your body needs fat to function properly. Healthy fats are an important part of a nutritious diet. They help you absorb vitamins, promote healthy cell growth, and provide energy.
There are four main types of healthy fats: saturated, monounsaturated, polyunsaturated, and omega-3 fatty acids. Saturated fats are found in animal products such as meat and dairy. Monounsaturated fats are found in olive oil and avocados. Polyunsaturated fats are found in nuts, seeds, and fatty fish such as salmon. Omega-3 fatty acids are found in fish oil, flaxseed oil, and chia seeds.
When choosing healthy fats, it’s important to focus on quality over quantity. The best way to do this is to limit your intake of processed foods and choose foods that are rich in healthy fats. Some good examples of healthy fat-rich foods include avocados, olive oil, nuts, seeds, and fatty fish.
Protein is an essential macronutrient that helps our bodies build and repair tissues, make enzymes and hormones, and boost immunity. It’s especially important for people who are trying to lose weight or build muscle.
There are two types of protein: animal protein, which is found in meat, poultry, fish, and dairy; and plant protein, which is found in beans, legumes, nuts, seeds, and whole grains. Both types have been linked with health benefits.
Animal protein is a good source of essential nutrients such as iron, zinc, and vitamin B12. It also contains all the essential amino acids (the building blocks of protein) that our bodies need to function properly. Studies have linked animal protein with a lower risk of heart disease, stroke, diabetes, and obesity.
Plant protein is a good source of fiber and vitamins such as magnesium, potassium, and folate. It also contains some of the essential amino acids that our bodies need. Studies have linked plant protein with a lower risk of heart disease and obesity.
So which type of protein is best for you? The answer may depend on your individual health needs. If you’re trying to lose weight or build muscle, animal protein may be the better choice because it’s more calorie-dense and contains more of the essential amino acids that our bodies need to function properly. If you’re trying to lower your cholesterol or blood pressure, plant protein may be the better choice because it’s lower in saturated fat and contains more fiber. If you have diabetes or kidney disease, you may need to limit your intake of animal protein because it can worsen these conditions. Talk to your doctor or a Registered Dietitian about which type of protein is best for you.
Probiotics are live bacteria that are beneficial to our health, and are found in some fermented foods like yogurt, sauerkraut, kimchi, and kombucha. They can also be taken as supplements. Probiotics help to keep our gut healthy by restoring the balance of good bacteria in our digestive system.
Some of the health benefits associated with probiotics include improved digestion, reduced risk of cardiovascular disease and obesity, stronger immunity, and better cognitive function. Probiotics have also been shown to help with conditions like IBS, Crohn’s disease, ulcerative colitis, eczema, and acne.
To get the most benefit from probiotics, it’s important to eat a variety of probiotic-rich foods or take a supplement that contains a variety of different strains of probiotics. Some of the best probiotic-rich foods include yogurt, sauerkraut, kimchi, kombucha, tempeh, miso soup, pickles, and certain types of cheese.
Antioxidants are nutrients that help keep your cells healthy. They can be found in many foods, including fruits, vegetables, legumes, grains, and nuts. Here are some of the most antioxidant-rich foods:
-Berries: Blueberries, blackberries, strawberries, raspberries
-Beans and lentils: Black beans, kidney beans, lentils
-Nuts and seeds: Walnuts, almonds, flaxseeds, pumpkin seeds
Dietary fiber is an important part of a healthy diet. It can help you feel full and may reduce your risk of heart disease, obesity, and type 2 diabetes.
Fiber is a type of carbohydrate that your body can’t digest. It passes through your body undigested and is excreted in your stool.
There are two types of dietary fiber: soluble and insoluble. Soluble fiber dissolves in water and is fermentable by gut bacteria. Insoluble fiber does not dissolve in water and is not fermentable.
Most plant-based foods contain both soluble and insoluble fiber, but the amount of each type varies. Here are some examples of high-fiber foods:
– Chia seeds
– Psyllium husk
– Brussels sprouts
Minerals are inorganic substances that are essential for human health. They can be found in the earth, water, and air, and are absorbed by plants. Animals ingest minerals when they eat plants or other animals. Humans obtain minerals through diet, either from eating plants or from eating other animals that have eaten plants.
Minerals are necessary for the proper functioning of many systems in the body, including the nervous system, skeletal system, endocrine system, and circulatory system. They are also necessary for the proper metabolism of carbohydrates, fats, and proteins. Minerals are involved in many biochemical reactions, including the production of energy, the synthesis of DNA and RNA, and muscle contraction.
There are two types of minerals: macrominerals and trace minerals. Macrominerals are minerals that are required in large amounts by the body (for example, calcium and magnesium). Trace minerals are minerals that are required in small amounts by the body (for example, iron and zinc).
Macromineral Function Sources
Calcium Regulates muscle contraction; needed for blood clotting; helps build bones and teeth Dairy products; dark green leafy vegetables; tofu; soybeans; nuts; seeds; fish with edible bones (such as sardines and salmon); some fortified foods (such as breakfast cereals, plant-based milks, and juices)
Magnesium Helps maintain normal nerve and muscle function; helps regulate blood sugar levels; needed for energy production; helps build bones Nuts; seeds; whole grains; green leafy vegetables; fish
Potassium Helps regulate blood pressure beans; lentils ; tofu ;nuts ;seeds ; broccoli ;spinach avocados , yogurt , bananas , apricots figs prunes raisins
Sodium Helps regulate blood pressure table salt ; soy sauce ; some processed foods such as lunch meats , canned soups , pizza Dough,, fast frozen dinners,, snacks such as pretzels chips,, crackers dips,, dressings sauces .salsa some cheeses cottage cheese buttermilk..salted nuts peanuts cashews sunflower seeds pickles olives relishes capers bacon smoked meats ham some cold cuts Seafood canned tuna anchovies sardines Caviar smoked salmon,, canned soups bouillon cubes beef chicken vegetable .miso paste .soy sauce teriyaki sauce Worcester sauce .barbecue sauces sports drinks electrolyte solutions infant formulas some over-the-counter medications laxatives ,buffered aspirin products heartburn antacids.. bronchodilators..cough syrups sodium chloride tablets nose drops contact lens saline solution.. intravenous fluids hydrating beverages enhanced waters ..some prescription medications beta blockers ACE inhibitors lithium carbonate diuretics corticosteroids estrogens testosterone patches gel injections implants creams.. inhalers nebulizers
Vitamins are organic substances that are required in very small amounts for the proper growth and development of animals and plants. There are two broad categories of vitamins: those that are soluble in water (hydrophilic) and those that are soluble in fats (lipophilic). The thirteen vitamins that have been identified as essential to human health belong to one or the other of these groups.
Water is the healthiest beverage you can drink. It is essential for life and has many health benefits.
Water is essential for our bodies to function properly. Every cell, tissue, and organ in our body needs water to work properly.
Water helps to:
– regulate our body temperature
– flush out waste and toxins
– lubricate our joints
– keep our skin healthy and hydrated
– improve our digestion
We need to drink around 8 glasses of water a day to stay hydrated.
