1. Sunbathing
Sunbathing is considered an effective method to enhance health. Sunlight plays a very effective role in synthesizing vitamin D, helping to increase calcium absorption and transportation. Sunbathing brings many health benefits. Despite discussions about seeking shade and applying sunscreen - even on cloudy days and during winter, it's hard to believe that exposure to sunlight with small doses can be beneficial. Sunbathing involves sitting or lying in the sunlight for a certain period. Sometimes intended just for sun tanning, if done correctly, this action also brings significant health benefits. Although the risks of excessive sun exposure have been well documented, high doses of vitamin D - when exposed to sunlight, our skin converts cholesterol into vitamin D - have been shown to help prevent some common diseases. The skin receives sunlight with the appropriate duration and timing will help the body produce vitamin D - an essential vitamin for calcium absorption and metabolism. Therefore, the elderly should sunbathe properly in the morning before 8:30 to increase calcium metabolism, promote bone formation faster.

2. Omega-3 for strong bones
Omega-3 fatty acids are well-known for their anti-inflammatory effects and also help protect against bone loss during aging. You can get plant sources of omega-3 fatty acids from chia seeds, flaxseeds, walnuts, and animal sources such as fatty fish, mussels... Omega-3 fatty acids are essential and beneficial for health. Omega-3 fatty acids are extremely important, providing powerful health benefits for your body and brain.
There are 3 types of omega-3 fatty acids: ALA, EPA, and DHA. Among these 3 types, EPA seems to be the best in fighting depression. DHA is a major structural component of the eye's retina. When you don't get enough DHA, vision problems can occur.
Supplementing with enough omega-3 is associated with reducing the risk of macular degeneration, a leading cause of permanent eye damage and blindness worldwide. Many studies have shown that omega-3 fatty acids, especially DHA, are very important for your brain and retina. Therefore, it is especially important for pregnant and breastfeeding women to supplement with enough DHA, as it can affect the health and intelligence of the baby in the future.
In addition, supplementing with enough omega-3 provides powerful health benefits for adults. This is especially true for longer-chain fatty acids such as EPA and DHA. Studies have shown that omega-3 fatty acids can protect against all types of diseases, including breast cancer, depression, attention deficit hyperactivity disorder, and various inflammatory diseases.
Because your body cannot produce them on its own, you need to get them from your diet.


3. Exercise promotes bone health
One of the best activities to promote bone health is weight-bearing or high-impact exercises aimed at stimulating new bone formation. Studies in children, including those with type 1 diabetes, have found that this activity increases the amount of bone formed.
Furthermore, exercising also helps prevent bone loss in older adults. Studies in older men and women performing weight-bearing exercises show increased bone density, strength, and size, as well as reduced signs of bone turnover and inflammation.
Strength training habits not only benefit muscle mass but also promote bone health, preventing bone loss in young and older women, including those with osteoporosis, osteopenia, or breast cancer.


4. Collagen for Strong Bones
Collagen is the main protein found in bones containing the amino acids glycine, proline, and lysine, helping to build bones, muscles, tendons, and other tissues. Collagen hydrolyzate is derived from animal bones and is often referred to as gelatin used to relieve joint pain.
Collagen accounts for about one-third of the body's protein, considered the richest protein compound in the body. It functions to build the structural framework of organs, bones, skin, muscles, tendons, and ligaments. Other structures like blood vessels, corneas, and teeth also contain collagen.
You can think of collagen as a type of adhesive, holding all the tissue cells tightly together. In Greek, collagen is called kólla, meaning glue.


5. Maintaining a Healthy Weight for Strong Bones
In addition to diet, maintaining a healthy weight can help support bone health. Low body weight is a major factor contributing to reduced bone density and bone loss in postmenopausal women. Research suggests that obesity can decrease bone quality and increase the risk of fractures due to excessive weight.
Although weight loss often leads to bone loss, it is typically less pronounced in obese individuals compared to those with normal weight. Maintaining stable or slightly higher weight than normal weight is the best way to protect your bone health.


6. Vitamin D and K for Bone Health
Vitamin D and vitamin K are essential components for promoting strong bones. Vitamin D plays a crucial role in helping your body absorb calcium. Your body needs to achieve a blood level of at least 30ng/ml (75nmol/l) of vitamin D to protect against osteoporosis, osteopenia, and other bone diseases. Studies have shown that children and adults with low vitamin D levels often have low bone density and are at higher risk of bone loss.
Vitamin K2 supports bone health by regulating osteocalcin, a protein involved in bone formation, allowing osteocalcin to bind with minerals in the bone and prevent calcium loss from the bone. You can supplement vitamin K2 through foods such as animal liver, eggs, and meat…
You can obtain enough vitamin D for strong bones by sun exposure and consuming sources of fatty fish, liver, and cheese. However, many people may need to supplement with up to 2,000 IU of vitamin D per day to maintain optimal levels.


7. Balanced Caloric Intake for Strong Bones
When you consume too few calories, apart from slowing down metabolism, inducing hunger, and causing muscle loss, this can also be detrimental to bone health.
Studies have shown that consuming less than 1,000 calories per day may lead to low bone density. In one study, obese women who consumed 925 calories per day for 4 months experienced a significant reduction in bone density in the upper hip and thigh regions, regardless of exercise.
To build and support strong bones, aim for a balanced diet providing at least 1,200 calories per day, including ample protein, vitamin-rich foods, and minerals that support bone health.


8. Protein for Strong Bones
Protein is crucial for maintaining strong bones, with about 50% of bones made up of protein. Researchers have reported that low protein intake reduces calcium absorption, which can affect bone formation and fracture rates. Older women appear to have better bone density with higher protein consumption.
In a six-year observational study involving over 144,000 postmenopausal women, higher protein intake was associated with significantly reduced risk of forearm fractures and higher bone density in the hips, spine, and overall body. Moreover, a diet containing a large proportion of calories from protein can help maintain bone mass during weight loss.


9. Calcium for Strong Bones
Calcium is the most important mineral for bone health. Old bone cells are constantly broken down and replaced by new cells, so you need to consume calcium daily to protect the structure and strength of your bones. Calcium-rich foods may include oats, tofu, almonds, various beans, shrimp, milk, and more.
The recommended calcium intake per day for healthy bones is typically 1,000mg for most people, around 1,300mg for adolescents, and about 1,200mg for older women.


10. Vegetables and Fruits for Strong Bones
Vegetables and fruits are among the good sources of vitamin C, which helps stimulate bone cell production. Additionally, some studies suggest the antioxidant effects of vitamin C may protect bone cells from damage. Fruits and vegetables also increase bone density, which is a measure of the amount of calcium and other minerals found in bones. Osteoporosis and osteopenia are characterized by low bone density.
Consuming a large quantity of green and yellow vegetables is associated with increasing the mineralization process, or bone mineralization, in early ages and maintaining bone mass in young individuals. A study in women over 50 found that those who consumed onions most frequently had a 20% lower risk of osteoporosis compared to those who consumed them less frequently.


11. Magnesium and Zinc for Strong Bones
Magnesium plays a crucial role in converting vitamin D into its active form to enhance calcium absorption. You can supplement magnesium through foods or use magnesium glycinate, citrate, or carbonate.
Zinc is an essential trace mineral that helps form the mineral component of bones, promoting bone cell formation, and preventing excessive bone breakdown. You can supplement zinc through foods such as beef, shrimp, spinach, flaxseeds, oysters, and pumpkin seeds.
