Osteoporosis – Love Your Bones; Protect Your Future

Osteoporosis: Protect Your Bones – Three Key Nutrients You May Be Missing

October 20th is World Osteoporosis Day. This year, the theme of the campaign is Love Your Bones; Protect Your Future, encouraging all of us to take early action to protect bone health.

From the age of 50, one in every three women and one in five men will suffer a bone fracture as a result of poor bone health. “The progressive bone loss that occurs with osteoporosis may be invisible and painless, but this ‘silent’ disease results in fractures which cause pain, disability, and ultimately loss of independence or premature death,” states Prof. John Kanis, President of the International Osteoporosis Foundation.

Fortunately, taking care to adopt a healthy diet and undertake regular exercise is well-known to help protect bone health in later years. Vitamin and mineral supplements containing key nutrients for bone health – such as calcium, magnesium, vitamins D and K, and boron – can also be a sensible way of providing additional protection.

While many of us are aware of the role of nutrients such as calcium and vitamin D in bone health, it is important to note that healthy bones are dependent on a whole host of nutritional factors. Below are the top three commonly overlooked bone-boosters.

1. Protein

In the past, there has been concern over the link between protein intake and bone loss. It was believed that high protein intake might result in loss of bone mass by causing calcium to be leeched from bones.

However, more recent research has found that, provided calcium intake is sufficient, adults with the highest protein intakes have the lowest rates of bone loss (1). Protein makes up about 50% of bone, and so bone requires a constant intake of protein to maintain its mass.

Ensuring a good intake of foods high in both calcium and protein is essential, especially for older people whose protein intake tends to be lower. For those who drink protein shakes, try adding in some calcium-rich kale, Greek yoghurt or a spoon of tahini or almond butter. Aside from dairy, good sources of both calcium and protein are canned salmon (with bones), tofu, almonds, white beans and sesame seeds. The top choice however, is tinned sardines which are cheap, easily available and also provide another little-known bone builder, omega-3.

2. Omega-3

Osteoporosis has strong links with inflammation, because inflammatory compounds have a direct effect on the cells that form and break down bone.

It is widely understood that omega-3 fats have an anti-inflammatory effect. While larger studies are needed to confirm this benefit, research to date is promising. For example, combining exercise with omega-3 supplements has been shown to improve bone density better than exercise alone (2). In a second study, a test diet with a higher amount of omega-3 fats was found to reduce bone breakdown, when compared with a typical Western diet (3).

Taking care to include sources of omega-3 in the diet is recommended to fight chronic inflammation. Omega-3 fats are abundant in oily fish, and are also present in leafy greens, chia and flaxseed.

3. Antioxidants

Oxidative stress is damage that occurs when free radicals attack our body. This can include damage to bone, by reducing bone formation and increasing bone resorption.

Women with osteoporosis have been found to have lower levels of antioxidant nutrients in their blood than women with healthy bones (4). Fortunately, antioxidants in both whole foods and supplements have been found to protect bone health (5,6).

Including antioxidant-rich foods would therefore appear to be a sensible way to help keep bones healthy. While some might choose an antioxidant supplement, key antioxidants are also easy to include in our daily diet. For example, blueberries and green tea supply flavonoids, tomatoes are a rich source of lycopene and red grapes provide resveratrol.

Carotenoids: Protect Your Skin From The Inside

Hopefully you have all been having a great time in the beautiful sunshine these last few days – it’s a great opportunity to spend more time outdoors. Whether that be pottering in the garden or going for long walks, having picnics in the park or barbeques with friends or sunbathing and enjoying everything else these warmer climes have to offer.

It is also a time when people start to think about their body shape and appearance as they dig out their summer clothes and dare to bare more skin. This is generally a very positive time for most people as our “winter blues” are improved and we begin to get more vitamin D from the sun and feel more energised. However, it is also a time when individuals can suffer from the negative effects from the sun such as prickly heat, sun stroke and sun burn. Damage to the skin from excessive sun exposure may not be a priority for those in their youth, however skin damage at any age is extremely detrimental and over time the harmful and ageing effects of the sun can become more apparent.

The skin is our largest organ and it provides us with a barrier against damaging pathogens entering our bodies such as bacteria and free radicals from our environment. In order to prevent these factors from entering our bodies, we need a high level of protection as they not only impact on our immune systems but they can also significantly contribute to ageing.

Tomatoes contain lycopene
Tomatoes contain high level of the antioxidant lycopene which can help towards anti-ageing

A recent review (1.) published by the journal Molecules analysed research findings available in the area of skin health and the effects of powerful antioxidant carotenoids such as beta-carotene, lutein, zeaxanthin and lycopene. These free-radical scavengers are found in brightly coloured fruits and vegetables  such as carrots, tomatoes and sweet potato.

The authors reported that these antioxidants enhance the skins ability to protect itself from oxidative stress as they act to mop up and destroy the free radicals that attempt to attack our skin and cause signs of ageing. However, the levels of these carotenoids are significantly affected by detrimental lifestyle factors. These include smoking or stress, poor diet, illness and exposure to the sun (especially  sunburn) and were reported to significantly reduce the levels of concentrations of antioxidant carotenoids in human skin.

These factors can result in skin damage as they reduce our level of protection and speed up the ageing process which can result in sun spots, pigmentation, lines and wrinkles and sagging of the skin. The authors reported that increasing levels of carotenoids in dietary and supplemental forms was reportedly one of the best defensive approaches against ageing.

Therefore to help keep looking and feeling young, youthful and radiant, make sure you top up your levels of carotenoids and limit your exposure to the sun to keep your levels of these antioxidants high. Raw carrots dipped in hummus, tomato salads or roasted butternut squash are some ways of incorporating higher levels of these antioxidants into your diet. If you can’t stand vegetables or want to supplement your diet with an extra boost, then a high quality carotenoid supplement could be considered.

As well as protecting your skin from the inside, it is also important to protect your skin on the outside with good quality, high factor natural sun protection cream. You can find more blog posts about natural sunscreens here.

The antioxidant advantage – introducing a new standard in Rosehip Oil

Trilogy Rosehip Oil Antioxidant+ is here!

Our busy daily lives see us constantly exposed to free radicals – microscopic organic molecules responsible for ageing and tissue damage. Pollution, sun exposure, diet and stress are just some of the sources of free radicals we deal with every day. They attack skin cells, causing them to break down and so affecting the health and the appearance of our skin.

Trilogy Rosehip oil Antioxidant+
Trilogy Rosehip Oil Antioxidant+ is a red berry seed oil blend which provides intensive nourishment.

Antioxidants provide a counter attack, helping stop free radical damage and providing protection for the skin. This ensures the integrity of healthy cells and helps to maintain a youthful, radiant complexion.

While our main source of antioxidants is through diet, the body is so hungry for these useful molecules that most of them are absorbed into our systems before they reach the outer layer of the skin. Choosing skincare with high antioxidant content ensures that the skin receives its own supply.

Trilogy Rosehip Oil Antioxidant+ contains red berry super antioxidants, such as lycopene from tomato and phytosterol from acai berry, providing powerful protection from free radicals and helping to prevent visible signs of premature ageing. Combined with Certified Organic Rosehip Oil, which is high in Essential Fatty Acids and delivers intensive nourishment and hydration to replenish softness and elasticity, these ingredients create the perfect skincare product, one which helps to repair yesterday’s damage and protect from tomorrow’s for healthier younger looking skin.
