How to support your health as you age 

Nutrition for Seniors and older adults

Are you interested in nutrition as you move into your “golden years” or wondering about nutrition for seniors? Small, practical changes can make a difference in overall well-being for older adults. Seniors have multiple factors influencing their eating habits. Perhaps decision fatigue from years of planning and preparing meals makes thinking about what you will prepare a challenge. You may find cooking difficult if you are a care taker for a loved one or perhaps you experience low appetite, fatigue, reduced mobility, or reduced interest in food. These are all potential barriers to adequate nutrition.

Although this article will focus on general nutrition tips to promote health, it is important to recognize that nutrition is not the only thing to consider during this life stage. Research demonstrates that loneliness is associated with cognitive decline in older adults and that having a strong support group and integrating meaningful activities into your life are also key to general well-being. Nutrition is only one piece to the puzzle!  

The following nutrition for seniors tips will hopefully bring some awareness of common nutrition concerns as we age and tips on how to manage them. This blog post covers nutrition tips for dehydration, constipation in seniors, vitamin B12 for seniors, and adequate protein intake. Keep reading to learn more!

1. Focus on Fluids  

There’s a higher risk of dehydration in seniors and older adults as as the body is less likely to send thirst signals and total body water stores decrease with age. Because of this, dehydration can occur quickly in seniors. Inadequate hydration can increase the risk for falls due to reduced blood pressure, dizziness, and confusion. It can also increase the risk for constipation and urinary tract infections. Severe dehydration can lead to delirium and is a significant medical concern. Some general signs of dehydration include dry mouth, dry tongue, rapid pulse, low blood pressure, confusion, and dizziness. It is recommended that seniors consume between 1.5-2.5 L of fluid daily (1,500-2,500 ml). Fluid needs are higher if vomiting and diarrhea are present or with increased sweating due to physical activity or being exposed to higher temperatures.  

A few tips to help with fluid intake: 

  • Use a water bottle with measurements on it to keep track of your fluid intake. Sometimes the visual reminder of having your water bottle around you can help 
  • Bring a water bottle with you on errands and ensure you have water on hand during any physical activity  
  • Consider adding flavouring to your water. A squeeze of lemon, cucumber slices with mint sprigs, or a small splash of juice can add delicious flavour and make it more exciting to drink  
  • Tea and coffee count towards fluid intake, however, they act like a diuretic- meaning they increase urine output. Balance out your intake of tea and coffee with water and/or milk  
  • Soup broth, popsicles, and watery fruits and vegetables (i.e. watermelon, tomatoes, cucumbers) count toward fluid intake  
  • If you take supplements or medication, consider taking them with a full glass of water versus sips  

2. Keep Things Moving with Fibre!   

The prevalence of constipation in seniors is 26% for women and 16% for men. Constipation can typically be helped with gentle movement, adequate dietary fibre intake, and increased fluid intake. It is recommended that older adults consume 21-30 grams of fibre daily. Fibre can be found in fruits, vegetables, whole grains, beans/legumes, nuts and seeds. If you are aiming to increase your fibre intake, it is also vital to increase fluid intake to keep things moving along. Adding fibre to the day may look like adding some sliced cucumbers or a handful of baby carrots at lunch. It could also look like adding an apple or banana to your breakfast in the morning. Small adjustments and changes can help improve fibre intake. Here is a sample day of eating that would amount to 27 grams of fibre: 

  • Breakfast: 1 package instant oatmeal, blueberries, and pumpkin seeds  
  • Snack: whole grain crackers and cheese  
  • Lunch: egg salad sandwich with lettuce on whole grain bread with sliced cucumber on the side  
  • Snack: apple and peanut butter  
  • Dinner: baked chicken thighs, 1 small baked potato, and roast asparagus  

It is important to note that there are other causes of constipation in older adults and fibre is not always the solution. If constipation has been a chronic concern or has worsened significantly, it is recommended you check-in with your primary care provider.  

3. Check Your B12  

Vitamin B12 is a micronutrient of interest in older adults as a deficiency is more prevalent as we age. In Canada, approximately 5% of the general population has a vitamin B12 deficiency.  As we get older, absorption of vitamin B12 is less efficient as well as certain medications that are commonly taken, such as stomach acid-reducing medications (proton pump inhibitors) and metformin can decrease absorption. Vitamin B12 is an important micronutrient as it impacts cognition, blood cell production, and the production of cell membranes and neurotransmitters. Some good sources of vitamin B12 include: 

  • Meat 
  • Fish 
  • Cow’s milk (if you drink a milk alternative, check that it is fortified with vitamin B12) 
  • Cheese 
  • Eggs 
  • Fortified breakfast cereal 
  • Nutritional yeast 

The best way to check for vitamin B12 deficiency is through a lab test with your doctor. If a deficiency is present, they will make recommendations on supplementation. Supplements are not necessarily needed if you have adequate vitamin B12 levels.  

4. Consider Protein 

As we age, muscle loss is common due to reduced food intake, impaired mobility, less protein uptake by muscles, and age-related changes in digestion and absorption. Considering your protein intake may be important if you often shy away from protein foods. I often recommend for clients to include a grain or starch, fruit or vegetable, and protein at every meal to promote adequate intake of all three macronutrients (carbohydrates, protein, and fat). Of particular interest for maintaining muscle mass is the amino acid leucine. Leucine is a branched-chain amino acid and there is good evidence to support that it helps “turn on” muscle synthesis. Leucine can be found in all protein foods in varying amounts. It is the highest in animal products but can be found in many protein-containing foods including meat, fish, dairy, peanut butter, nuts, peas, and cheese.

How can you increase protein intake during the day? 

  • Consider adding Greek yogurt to things like smoothies or oatmeal. It also makes a great snack and can be topped with nuts, seeds, or granola  
  • Nuts and seeds can easily be sprinkled on top of breakfast cereals, yogurt, oatmeal, or on salads  
  • Consider adding nut butter to toast instead of just jam or butter  
  • Milk contains 8 grams of protein per 1 cup and can be an easy protein source 
  • Eggs can be an easy protein source as they can be cooked in minutes 
  • Add cheese to things such as salads, eggs, mashed potatoes, and pasta  
  • Although it is always recommended to consume food first if you are struggling to include protein a nutrition supplement drink or protein powder can help. I recommend consulting with a dietitian to determine what is best for you.

“This is the first time I feel satisfied; my cravings have diminished dramatically and I have a whole new relationship with food. I am eating guilt-free for the first time in my life. My energy has also dramatically increased and I feel great!
Rhonda Jenkins, Nutrition Counseling Client
“The Dieticians at Health Stand Nutrition help you to take action on the science behind eating well by making it practical, understandable, and fun. Their office is cozy and not at all clinical or intimidating. I felt like I was sitting down with a really smart, caring friend who wanted to help me make the best choices for my lifestyle and food preferences. They really are the best in the business.”
Marty Avery, Nutrition Counseling Client
“I have come to think of the program as a one stop shopping excursion for everything one needs to know about creating a joyous relationship with food and our bodies. In a single word, the course has gifted me with freedom from the punishing rigidity of disordered eating, old stories that never were true, and body dysmorphia that did nothing but make me lose sight of a body that has done everything I've asked, despite my careless dismissal of her needs. Now when I look in the mirror I find myself shifting from harsh criticism to gentle gratitude.”
Lynn Haley, Pursuit of Healthiness Online Course Participant
“I spent 3 hours when first diagnosed with type 2 diabetes. I learned more from my Dietitian about food in those 3 hours than I had learned in all the years of my life. I also love the newsletter, there is always something to learn.”
Peter Whitehead, Nutrition Counseling Client
“I didn’t realize how strong my “diet mentality” was, and all the rules I had in my head about food. I was in a cycle of reward/punish/binge/cringe. I booked with your business very reluctantly, on the repeated advice of my doctor, to get my slowly rising cholesterol levels in check. I thought I knew everything about food, and my behaviour with food, but I was definitely re-schooled. My weight is creeping down, I feel good about my diet, exercise, body image, and lifestyle.”
Amy Floyd, Nutrition Counseling Client
“Thanks Andrea for an amazing presentation, I have heard all positive remarks from attendees and the evaluations show the same sentiment. It is really gratifying when a speaker does their “homework” and weaves in our profession’s day to day challenges within their content, you did an awesome job of this! You truly took the “die” out of Dietician! Your information on healthy eating and simplifying how we can work towards this as we are all so busy really hit the mark. Andrea connects very well with her audience; she is energetic, funny, and very approachable.”
Carole Ann LaGrange, Transfusion Medicine Safety Officer

Event Planner for Laboratory Diagnostic Imaging Annual Event

I am a family physician who sees patients with a myriad of eating concerns – from wanting to know how to plan healthy meals for active families, to weight loss, to eating disorders, and so on. I cannot recommend the Health Stand team highly enough. I have worked with (and been to!) other Dieticians in the past and too often find that they just ask for food logs and make suggestions that are easily obtained online or in books. The Dieticians at Health Stand offer much more than just telling clients what they “should be eating.” In contrast, the team really does more of a counselling practice, and they work hard to help their clients learn more about why their eating habits may be off track and not optimal for them, as well as helping people to effect change at a deep level that, most importantly, is sustainable for lifetime health.”
Dr. Deb Putnam, Family Physician

“I am a busy mom, with kids in high level sports, working full-time downtown, and running our home acreage outside the City. I now have the knowledge and tools I need to plan for and manage the chaos of meal planning.”
Gillian Gray, Pursuit of Healthiness Online Course Participant
“As a construction company, we select speakers who can relate to our industry and its employees. Andrea’s message was delivered with humor and empathy. She makes people feel as though they can make changes without leaving behind every favorite food. Andrea focused her presentation on healthy eating as a way to keep energy high throughout the day. This message and the way it was delivered resonated with our predominantly male, blue collar culture. I would highly recommend Andrea as a speaker for groups such as ours. She will get your message across without alienating anyone in your audience – which is a huge hurdle when trying to introduce a wellness program in the workplace!”
Stephanie Wood, HR and Safety Manager

Fisher Construction Group, Burlington, WA

I found my Dietitian warm, funny, and skilled at teaching nutrition concepts without the overwhelm. The general approach of each session was to mix science with emotion, which was exceedingly effective in helping me shift my perspective on food from one of anxiety to one of joy and curiosity.”
Erin Kronstedt, Nutrition Counseling Client
“Excellent presentation! What a refreshing change to have a speaker inspire rather than “lecture” about nutrition. Your captivating stories, tips and overall approach to healthy eating uplifts and puts people at ease. It was great to hear we don’t need to strive to be perfect eaters, and that small changes really can make a difference in how we feel and in our health. Thanks to Andrea, we have solutions to our everyday nutrition challenges that can actually work in real life!”
Tina Tamagi, Human Resources
