What You'll Learn
Increase calcium intake
Calcium is a critical mineral for bone health, and increasing calcium intake can help prevent bone loss and osteoporotic fractures in older people. The recommended daily intake of calcium for adults is generally between 1,000 and 1,200 milligrams, but the typical diet often provides much less.
To increase calcium intake, it is important to include calcium-rich foods in your diet. Dairy products such as milk, yoghurt, and cheese are some of the richest dietary sources of calcium. One 8-ounce serving of skim, low-fat, or whole milk contains about 300 milligrams of calcium. Other calcium-rich foods include nuts, leafy greens, and fish. Fortified foods such as juices, breakfast foods, soy milk, cereals, snacks, breads, and bottled water can also contribute to calcium intake. However, it is important to shake the container well before consuming calcium-fortified liquids, as calcium can settle at the bottom.
In addition to dietary sources, calcium supplements can help increase calcium intake. However, it is important to note that calcium should not be taken in isolation. Vitamin D is essential for proper calcium absorption, and magnesium helps direct calcium to the bones. Therefore, it is recommended to choose a calcium supplement that includes both calcium and vitamin D. Before taking any supplements, it is always advisable to consult with a healthcare professional to ensure they are suitable for your individual needs.
While increasing calcium intake is important, it is also worth noting that certain dietary habits can contribute to calcium loss. Excessive alcohol consumption can hasten bone loss and reduce the body's ability to absorb calcium. Caffeine, found in coffee, tea, and soft drinks, can slightly increase calcium loss during urination and interfere with calcium absorption. Additionally, phosphorus, commonly found in colas and processed foods, can interfere with calcium absorption in the small intestine. Therefore, it is important to consume these foods and beverages in moderation and ensure that your diet contains adequate calcium to minimise potential negative effects.

Limit alcohol and caffeine
While a healthy, balanced diet is essential for maintaining bone health, certain dietary modifications are necessary for older adults experiencing bone loss. One crucial aspect is limiting alcohol and caffeine intake.
Alcohol consumption can significantly contribute to bone loss. Studies have shown that consuming more than one or two alcoholic drinks per day accelerates bone loss and impairs the body's ability to absorb calcium. Alcohol can reduce calcium absorption, and heavy drinking can lead to osteoporosis and an increased risk of fractures. Therefore, it is recommended that alcohol be consumed in moderation, with a limit of one drink per day for women of all ages and men over 65, and up to two drinks per day for men 65 and younger.
Caffeine, commonly found in coffee, tea, and soft drinks, can also impact bone health. While moderate caffeine consumption of about two to three cups of coffee per day is generally considered acceptable, excessive intake can slightly increase calcium loss during urination. Additionally, substituting caffeinated beverages for milk or other healthy drinks can negatively affect bone health. Caffeine may decrease calcium absorption, and when combined with other factors such as a calcium-deficient diet, it can contribute to bone loss.
It is worth noting that the impact of caffeine on bone health may vary depending on individual factors and overall dietary habits. While caffeine can slightly increase calcium excretion, the primary concern lies in its potential to replace calcium-rich beverages in one's diet. Therefore, ensuring adequate calcium intake and choosing caffeinated drinks in moderation can help mitigate any potential negative effects on bone health.
To summarize, limiting alcohol and caffeine intake is crucial for older adults experiencing bone loss. Alcohol can directly contribute to bone loss and impair calcium absorption, so moderation is essential. While caffeine can slightly increase calcium loss, its main impact on bone health is through substitution with healthier drink options. By making conscious choices about alcohol and caffeine consumption, older adults can help maintain bone health and reduce the risk of further bone loss.

Eat more fruit and vegetables
Eating more fruits and vegetables is a great way to improve bone health. Aim for four or more servings of vegetables and three servings of fruit each day. Fruits and vegetables are excellent sources of magnesium and potassium, as well as vitamins C, K, and A, all of which play a role in maintaining bone health. They are also high in fibre and typically lower in calories and fat.
Fruits and vegetables contain phytochemicals, which are substances that can protect against various diseases, including osteoporosis. Some great bone-healthy fruits include prunes, dried figs, oranges, and white beans. Prunes, in particular, have been found to boost bone strength, with studies showing that eating five or six prunes a day helped postmenopausal women preserve bone mineral density in their hips.
When it comes to vegetables, dark greens are a great source of calcium. For example, each cup of white beans contains about 190 mg of calcium. Other calcium-rich vegetables include spinach, although it should be noted that spinach also contains oxalate, which reduces calcium absorption. Therefore, while spinach is a good source of calcium, it may not be the best source for those solely looking to increase their calcium intake.
In addition to increasing fruit and vegetable intake, it is important to also include adequate amounts of calcium and vitamin D in your diet, as these are critical for bone health. Calcium is a key building block of bones and helps prevent bone loss and osteoporotic fractures. Vitamin D helps the body absorb calcium.

Consume vitamin D
Vitamin D is essential for bone health, especially for older people experiencing bone loss. It helps the intestines absorb calcium from food, keeping bones dense and strong. While the body can produce vitamin D when sunlight touches the skin, older adults tend to produce less vitamin D due to reduced sun exposure, less physical activity, and increased use of sunscreen. Additionally, the body's ability to synthesise vitamin D decreases with age.
Vitamin D-rich foods include fortified milk, orange juice, and soy milk. However, it can be challenging to obtain sufficient vitamin D from sunlight and diet alone, especially for those with underlying conditions. In such cases, vitamin D supplements may be recommended to achieve optimal levels, typically agreed upon as 30-60 ng/ml of 25-hydroxy vitamin D.
For older adults with osteoporosis or low bone mass, consulting a healthcare provider is crucial to ensure adequate vitamin D intake. Before considering supplements, it is important to check if other multivitamins or medications already contain vitamin D. Additionally, calcium supplements that include vitamin D can be beneficial, as calcium is vital for bone health and works synergistically with vitamin D.
It is important to note that excessive salt intake can lead to increased calcium loss through urination, which can weaken bones over time. Therefore, limiting salt consumption and prioritising vitamin D and calcium-rich foods or supplements can help maintain bone health in older adults experiencing bone loss.

Avoid high-salt foods
It is important to avoid high-salt foods when aiming to prevent bone loss in the elderly. Eating foods with a lot of salt (sodium) causes the body to lose calcium, which is a key building block of bone health and can lead to bone loss. Calcium is critical to preventing osteoporotic fractures in older people, and too much salt causes the body to excrete more calcium during urination.
To avoid this, aim to consume no more than 2,300 mg of sodium per day. To put this into perspective, this is the equivalent of about 1 teaspoon of salt per day. Check the Nutrition Facts label on food packaging; if it lists 20% or more for the % Daily Value, it is high in sodium and should be avoided.
High-salt foods to avoid include processed foods, canned foods, and salted foods. Phosphorus is often used as an additive in processed foods, and too much phosphorus can interfere with how much calcium is absorbed through the small intestine. Canned foods can also be high in salt, so it is best to limit the amount of canned food consumed. In addition, try to avoid adding salt to foods during cooking and at the table.
Instead, opt for fresh, unprocessed foods whenever possible. This includes a variety of fruits and vegetables, which are excellent sources of magnesium, potassium, and vitamins C, K, and A, all of which play a role in maintaining bone health.
