Modern lifestyles, dietary habits, stress, and environmental factors can all influence the body's ability to obtain and utilize essential nutrients effectively. When these demands are not met, nutrient deficiencies may develop and impact energy, immunity, mood, and overall wellness. Understanding your unique nutritional needs is an important step toward maintaining long-term health and supporting optimal body function. In this article, we'll explore common nutrient deficiencies, the role of supplementation, and practical ways to support overall wellness through balanced nutrition.
What Are The Fundamentals of A Healthy Diet?
Most people know that even though they can be tasty, fried foods and chips do not support a healthy diet. However, even healthy diets can miss important nutrients. Current Canadian guidelines focus on balanced eating patterns instead of serving targets. Adults should eat plenty of vegetables and fruits every day. Canada's food guide encourages making vegetables and fruits half your plate. The guide also recommends whole grains and protein-rich foods. Building balanced meals every day takes planning and consistency. Vegetables and fruits provide vitmains, minerals, fibre, and antioxidants. Some healthcare practitioners recommend higher fruit and vegetable intake for additional nutrient support. Even with healthy habits, some people struggle to meet their nutritional needs consistently.
Variety also plays a big role here and needs to be addressed. VARIETY is important. You may eat a salad for every meal, but are you varying the toppings? Are you trying to incorporate a variety of other vegetables, nuts, seeds, cheeses, beans, lentils, oils, etc.? In order to round out and boost the nutritional value of your everyday salad, variety is essential. We all have likes and dislikes; the key is not to get so stuck in our patterns that we are getting more than enough of certain nutrients and none of others.
Again, by no means am I saying that it is impossible to meet our nutritional goals via food, nor that you shouldn't try! In fact, I encourage everyone reading this article to spend the next week counting their servings of each of the food groups and sticking to Canada's Food Guide's recommendations. I guarantee you will feel great, but some of you may also find that it takes a little planning and can be challenging to follow on a daily basis.
It is for all the reasons above that a high-quality multivitamin or a daily greens supplement may be essential, to give certain vitamin and nutrient levels a boost and put you up to the recommended quantities of essential vegetables and fruits.
The Evolution of Food Nutrients
My mother grew up on a farm. If she needed eggs, she ran out to the chicken coop and grabbed them; if she needed milk, she took it straight from the cow. She did not have a microwave to heat up insta-meals packaged in plastic. Was she healthier for it? I think so!
Modern lifestyles often prioritize convenience over nutrition. Food production has changed to meet growing consumer demands. Manufacturers often processstaple foods to improve shelf life and scalability. Processing can reduce certain nutrients in some foods. Manufacturers also add preservatives, colours, flavours, and texture enhancers to many products. These additions can increase palatability and shelf stability. Many farms now use pesticides and other agricultural chemicals more frequently. Researchers continue studying how these practices affect human health and food quality. Some evidence suggests soil quality and mineral content have changed over time. Modern diets also include more heavily processed foods than previous generations. Environmental changes may affect food systems, crop quality, and animal health. These factors can influence the nutritional quality of the foods we eat.
Lately, we have heard a great deal about the importance of Omega-3 fatty acids. Simultaneously, we are learning more and more about the heavy metal content, mainly mercury, of many of our tastiest fish friends. Fish oil is a prime example of a supplement that is becoming more and more necessary in order to minimize our levels of mercury while still getting in the essential Omega-3 fatty acids, needed to reduce the risk of heart disease, lower cholesterol and protect against a variety of neurological concerns.
Changing Nutritional Needs
Nutritional needs change throughout life. Stress, medications, and lifestyle habits can also affect nutrient requirements. People sometimes need extra vitamins and minerals during certain life stages. Healthcare providers commonly recommend prenatal vitamins during pregnancy. Some children may benefit from supplements if diet quality remains limited. Teenagers may need extra calcium during periods of rapid growth. Older adults often need more calcium and vitamin D support. Some older adults may also benefit from additional B vitamins. Postmenopausal women have higher calcium needs. Reduced absorption and age-related changes contribute to these increased requirements. Calcium supplementation may help slow bones loss after menopause. This support may help reduce osteoporosis risk in susceptible groups. Women with heavy menstrual cycles may benefit from additional iron intake.
Some needs change with the seasons. Many people know vitamin D as the sun vitamin, but during our cold Canadian winters, it doesn't matter how much sun there is; we are simply not able to absorb this much-needed vitamin through our skin (and are very rarely outside with skin exposed). For this reason, vitamin D supplementation throughout the winter months is essential. Many Canadians get so deficient throughout the winter that it is recommended they supplement year round to compensate for the deficiency.
We are all susceptible to the odd cold or flu, no matter how well we eat. When our immune system is compromised, our body is smart and uses up the resources it has in order to fight these bugs. In cases like this, supplements like vitamin Care necessary to boost these depleted levels. When smart bugs get the best of us, antibiotics are often prescribed. Although they do a great job of getting rid of nasty bacteria, they also completely wipe out the population of good bacteria within our gastrointestinal tract. Probiotic and prebiotic supplementation is an effective way to repopulate these good bacteria in order to prevent dysbiosis.
Even as exercise habits change, so do nutritional needs. Bodybuilders, marathon runners, and individuals looking to shed a few pounds need to make sure they are supporting their bodies' changing needs as they exercise. A high-quality protein powder, for example, is made to be absorbed quickly and efficiently, providing essential amino acids in the smallest number of calories and may prove to be an essential and complimentary addition to any athlete's daily diet. Free radicals are generated more quickly during exercise, and as such, athletes may also want to consider supplementing with antioxidants after especially taxing workouts.
Key Nutritional Needs
Herbs
People have used medicinal plants for centuries to support health and wellness. Historically, people consumed these plants whole or brewed them into teas. Today, manufacturers often sell herbs as capsules, powders, or liquid tinctures. Many herbs have long histories of traditional use. Researchers continue studying their roles in health and disease management. Some people use herbs like astragalus, echinacea, and goldenseal for immune support. Research on these herbs shows mixed results for cold and flu prevention. These herbs should not replace medical care when symtpoms are severe. Many common spices also contain bioactive compounds. Examples include oregano, turmeric, and cinnamon. People often consume small amounts of these spices in foods. Research studies sometimes use larger amounts than typical dietary intake provices. Supplement forms can offer a more conventrated and convenient option.
What Supplements Help Nutrient Deficiencies?
Supplementation is especially important if the deficiency has gotten so low as to affect the health of the individual.
Magnesium deficiency and low intake remain common in North America. Many people consume less magnesium than recommended through food alone. Low magnesium intake can make restoring healthy levels more difficult. Food sourcrs remain important, but dietary changes can feel overwhelming at first. Supplementation may help bridge nutritional gaps while improving dietary habits. Many people use magnesium supplements alongside magnesium-rich foods. Some people reduce or stop supplementation once diet alone maintains healthy intake levels.
Iron deficiency anemia can make rebuilding iron stores through diet alone difficult. Iron supplements may restore iron levels more efficiently in some cases.
People with inflammatory bowel diseases, like IBD, often experience nutrient malabsorption. Malabsorption may affect fat-soluble vitamins, including vitamin E. Nuts, seeds, and leafy greens provide vitamin E. Intestinal inflammation may reduce nutrient absorption from foods. Multivitamins may help support nutrient intake when diet alone falls short. Adequate fat-soluble vitamin intake remains important for overall health. Vegetarians and vegans may struggle to get enough nutrients from food alone. Vitamins B12, D, and A may require extra attention. This is where supplementation may be beneficial.
Prevention plays an important role in long-term health. Talk with your healthcare provider about your diet, habits, and family history. Use this information to assess your nutritional needs and support overall wellness.
