Nutrition explained by Dr. Jen Ashton

Nutrition -

Some believe they are not necessary. If you want to explore taking a supplement, first check with your doctor. He or she can advise whether they are needed and help choose the appropriate over-the-counter brand. The FDA monitors disease-related claims on dietary supplement labels but does not ensure whether a product contains the ingredients listed on its label.

Proper nutrition becomes even more important after men and women reach age It helps keep energy levels up and protects against many age-related illnesses and diseases like heart disease, cancer, and diabetes. But is there a best diet for men and women over 50? There is no single way to eat for good health.

While details may vary from diet to diet, all healthy eating plans have four basic principles in common:. With a bit of preparation and planning, it can be easy to create healthy meals for the entire week.

Meal prep has many benefits: It can help save time and money and help with portion control for weight management. It also reduces the stress of daily decisions about what to eat. Here are some steps on how to meal prep. Gather meal ideas. Collect healthy recipes and save them in a binder or copy recipe links onto an online spreadsheet.

Consider specific meals or foods for different days of the week, like Meatless Mondays, Whole Grain Wednesdays, and Stir-Fry Fridays. Begin small: Create enough dinners for two to three days of the week, and then go from there. Pick a day.

Choose a specific day of the week to do the following:. Some of these days may overlap but breaking up these tasks can keep meal planning manageable.

Cook in order. On meal prep day, focus first on foods that take the longest to cook. If you prefer not to pre-cook proteins, consider marinating poultry, fish, or even tofu on your prep day so you can pop them into the oven or stir-fry them later in the week.

While foods are baking or bubbling on the stovetop, chop vegetables and fresh fruit, or wash and dry salad greens for later in the week. Make extras. When possible, make extra portions of recipes for another day or two of meals, or freeze them for the following week.

Label all prepped items with a date so that you can track when to use them. Store highly perishable items like greens, herbs, and chopped fruits front and center at eye level, so you remember to use them.

Freeze cooked meals in airtight containers. Stock up. Work at stocking your kitchen with the following staples. This ensures you always have the basics on hand for meal prep and when you need to suddenly whip up healthy meals.

Beyond the usual suspects for healthy resolutions. Dog food and cat food in particular are heavily studied and typically include all essential nutrients for these animals. Cats are sensitive to some common nutrients, such as taurine , and require additional nutrients derived from meat.

Large-breed puppies are susceptible to overnutrition, as small-breed dog food is more energy dense than they can absorb. Most plants obtain nutrients through inorganic substances absorbed from the soil or the atmosphere. Carbon, hydrogen, oxygen, nitrogen, and sulfur are essential nutrients that make up organic material in a plant and allow enzymic processes.

These are absorbed ions in the soil, such as bicarbonate , nitrate , ammonium , and sulfate , or they are absorbed as gases, such as carbon dioxide, water, oxygen gas, and sulfur dioxide. Phosphorus, boron, and silicon are used for esterification. They are obtained through the soil as phosphates , boric acid , and silicic acid , respectively.

Other nutrients used by plants are potassium, sodium, calcium, magnesium, manganese, chlorine, iron, copper, zinc, and molybdenum.

Plants uptake essential elements from the soil through their roots and from the air consisting of mainly nitrogen and oxygen through their leaves. These hydrogen ions displace cations attached to negatively charged soil particles so that the cations are available for uptake by the root.

In the leaves, stomata open to take in carbon dioxide and expel oxygen. Most plants, therefore, require nitrogen compounds to be present in the soil in which they grow. This is made possible by the fact that largely inert atmospheric nitrogen is changed in a nitrogen fixation process to biologically usable forms in the soil by bacteria.

As these nutrients do not provide the plant with energy, they must obtain energy by other means. Green plants absorb energy from sunlight with chloroplasts and convert it to usable energy through photosynthesis. Fungi are chemoheterotrophs that consume external matter for energy. Most fungi absorb matter through the root-like mycelium, which grows through the organism's source of nutrients and can extend indefinitely.

The fungus excretes extracellular enzymes to break down surrounding matter and then absorbs the nutrients through the cell wall. Fungi can be parasitic, saprophytic, or symbiotic. Parasitic fungi attach and feed on living hosts, such as animals, plants, or other fungi.

Saprophytic fungi feed on dead and decomposing organisms. Symbiotic fungi grow around other organisms and exchange nutrients with them. Protists include all eukaryotes that are not animals, plants, or fungi, resulting in great diversity between them.

Algae are photosynthetic protists that can produce energy from light. Several types of protists use mycelium similar to those of fungi. Protozoa are heterotrophic protists, and different protozoa seek nutrients in different ways.

Flagellate protozoa use a flagellum to assist in hunting for food, and some protozoa travel via infectious spores to act as parasites.

Mixotrophic protists will typically depend on one source of nutrients while using the other as a supplemental source or a temporary alternative when its primary source is unavailable. Prokaryotes , including bacteria and archaea , vary greatly in how they obtain nutrients across nutritional groups.

Prokaryotes can only transport soluble compounds across their cell envelopes, but they can break down chemical components around them. Some lithotrophic prokaryotes are extremophiles that can survive in nutrient-deprived environments by breaking down inorganic matter.

This is common among bacteria that form in mats atop geothermal springs. Phototrophic prokaryotes typically obtain carbon from assimilating carbon dioxide through the Calvin cycle.

Some prokaryotes, such as Bdellovibrio and Ensifer , are predatory and feed on other single-celled organisms. Predatory prokaryotes seek out other organisms through chemotaxis or random collision, merge with the organism, degrade it, and absorb the released nutrients.

Predatory strategies of prokaryotes include attaching to the outer surface of the organism and degrading it externally, entering the cytoplasm of the organism, or by entering the periplasmic space of the organism.

Groups of predatory prokaryotes may forgo attachment by collectively producing hydrolytic enzymes. Contents move to sidebar hide. Article Talk. Read Edit View history. Tools Tools.
