USANA BiomegaArticle from USANA Australia Product News Letter 2016

A healthy body needs a mix of nutrients including proteins, carbohydrates and fats – yes fats! Fats are a major macronutrient and they provide a concentrated source of energy plus, they help the body to absorb nutrients such as fat-soluble vitamins and some antioxidants. The trouble is that most of us consume too much fat in general. Also, the vast majority don’t get enough of one fat in particular – the omega-3s. Are you getting your fats right?

Fats are grouped according to their chemical makeup and each type of fat affects the body differently. Most of us need to cut down on our total fat intake and especially avoid foods that are high in saturates.

More about omega-6 fats

Omega-6 (and omega-3) fats play a crucial role in heart and brain function and in normal growth and development. Vegetable oils such as sunflower, safflower, and corn oil, meat, eggs and dairy are major contributors of omega-6s. Most of us get plenty of omega-6s but not enough omega-3s. Even so replacing saturated fats with polyunsaturated fatty acids (PUFAs) is a heart healthy move. One study showed that swapping saturates with PUFAs can cut heart disease risk by nearly a quarter!

More about omega-3 fats

Omega-3 fats contain two key ingredients; long chain fatty acids called eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Vital building blocks for the production of cell membranes, EPA and DHA are needed to produce hormones, to protect the immune system, for healthy cell growth and much more…

  1. Brain and nervous system health. Much of your brain tissue is made from omega-3 fats so for healthy brain development and function, long chain omega-3 fatty acids (specifically DHA) are a must throughout life.
  2. Anti-inflammatory action. Omega-3 fats have anti-inflammatory effects. And, because inflammation is behind many chronic (long-term) conditions such as heart disease and joint inflammation, raising your intake of omega-3s may help reduce the risk of these, plus conditions such as osteoarthritis and rheumatoid arthritis.
  3. Heart health. Getting enough omega-3s may help to lower a type of fat called triglycerides as well as total cholesterol (both can increase your risk of heart and blood vessel conditions). Omega-3s may also help to increase HDL-cholesterol levels (the healthy type of cholesterol because it helps to eliminate cholesterol from the body).
  4. Eye health. According to the Linus Pauling Institute, omega-3s may protect against age-related macular degeneration, the most common cause of blindness in older people.
  5. Pregnancy and breastfeeding. Long-chain omega-3s can have a positive effect on visual and cognitive (brain) development in the growing baby.
  6. Prostate health. A recent study has suggested a link between consumption of DHA and total marine fatty acid intakes with a lower risk of death from prostate conditions.
  7. Cell ageing. Other research suggests that omega-3s can help the cells resist ageing. Scientists measured blood levels of omega-3 oils from fish (DHA and EPA) and then isolated white blood cells to measure the markers that signal ageing. Their findings, say the researchers, ‘raise the possibility that omega-3 fatty acids may protect against cellular ageing’.

If fish is the best source of omega-3s, how did inland early man survive?

The first humans were hunter gatherers. Unlike most of us today, they didn’t just eat the muscle meats of a hunted animal – they also ate omega-3 rich organ meats like the brain and bone marrow. Today, game i.e. wild-caught animal meat still contains more omega-3s than grain-fed, farmed livestock. Studies also suggest that the high levels of omega-6 fats many of us consume may reduce the absorption of omega-3s, especially DHA.

Finding nature’s antifreeze

Omega-3 fats don’t solidify even in very cold temperatures. This is important for fish living in cold ocean waters – without this kind of natural anti-freeze, the fish would literally freeze! In your body, this property helps blood vessels to remain flexible.

The richest sources of polyunsaturated essential fats include cold water fish like salmon, mackerel, trout and fresh tuna.

Some white fish and shellfish contain long-chain omega-3s, but not as much as oily fish. The main shellfish sources of long-chain omega-3s are mussels, oysters, squid and crab.

Fish oil is another good source of essential omega-3 fats.

Could you be short on omega-3s?

Early humans were hunter-gatherers who ate a diet that contained roughly a 1:1 ratio of omega-6 to omega-3 fats. Today, the typical ratio is around 15:1 a vastly lowered intake and ratio of omega-3 fats. In Japan where fish is a staple food, the ratio is 4:1 and the population is considered to be one of the healthiest worldwide.

One reason that we could be falling short of omega-3s is that the modern day diet doesn’t offer as many sources of these fats compared with times gone by. Because marine animals are the richest source of long chain omega-3s, you need to actively seek out fish and seafood and eat it regularly. Yet we have many more opportunities to consume saturates and omega-6 fats because we tend to eat more animal products and manufactured foods and more vegetable oils.

Also, because omega-6 fats and omega-3s are similar in makeup, when you eat more omega-6 fats, they compete against omega-3 fats for the same enzymes (substances that speed chemical reactions). So, the more omega-6 that you consume, the more enzymes will be used up leaving fewer enzymes to convert omega-3 fats into antiinflammatory chemicals needed to keep the inflammatory process in check. When the ratio is greatly out of balance, high levels of omega-6 replace and even reduce omega-3 fats.

Getting the balance right

Some experts say that consuming too much omega-6 and so little omega-3 fats can trigger inflammation which may then lead to heart disease and other conditions. Others suggest that omega-6 doesn’t have this effect. The majority agree, though, that in the average western diet, you’re likely to get so many omega-6s that reducing your intake may bring health benefits.

Cutting your intake of omega-6s and increasing your intake of omega-3s can help you to get the balance right.

The Heart Foundation (Aus) recommends an intake of 500mg/day EPA and DHA. Around 1000mg of omega-3 (marine source) daily is recommended if you have heart disease. Studies in the UK suggest that a massive nine out of ten British people fall short of this amount and the figure is likely to be similar here in Australia and New Zealand.

Ways to get the balance right

USANA-BiOmegaNewsletterEN

  • Eat more fish. Go for two fish dishes a week – a serve is around 170-200g (raw fish weight) or 110-140g of canned or cooked salmon. Good sources of omega-3s include salmon, herring, sardines, fresh tuna, snapper and scallops.
  • Eat more vegetarian sources of omega-3s. These include walnuts, flaxseeds (freshly ground), soybeans and tofu and leafy vegetables such as kale. These contain a precursor chemical, a short chain omega-3 called alpha-linolenic acid called (ALA) which the body can use to form the long-chain fatty acids EPA and DHA. But the conversion process isn’t very efficient. According to one review, between eight and 20 per cent of ALA is converted to EPA in humans and between 0.5 to nine per cent of ALA is converted to DHA. Levels of the enzyme needed to convert ALA to EPA and DHA decline with age.
  • Switch oil. Cook and stir-fry with just a little canola oil which contains ALA. Or replace butter, vegetable and sunflower oils with olive oil, macadamia or avocado which contain heart-healthy monounsaturates.
  • Sprinkle on seeds. Try chia seeds – these were an important staple of the ancient Aztecs and Mayans, chia seeds also contain bone building minerals including calcium, phosphorus and magnesium.
  • Try tofu. Add tofu to stir-fries or stir soya beans in to casseroles and curries.
  • Snack smart. Try delicious walnuts which also contain antioxidants including ellagic acid to support a healthy immune system.
  • Cut down on processed foods – manufacturers often use omega-6 rich vegetable oils.

What about fish oil supplements?

Fish oil (derived from the flesh of cold-water fish, such as salmon, mackerel, herring, sardines and anchovies) is a naturally powerful anti-inflammatory. Supplementing your diet is useful for general health and in the treatment of a range of conditions.

For example:

Heart health – fish oil supplements may help to improve blood flow thus helping to maintain healthy heart circulation and cardiovascular health.

Joint health – fish oil can help decrease joint inflammation associated with arthritis. One study showed that supplementation could reduce requirement for antiinflammatory medication in patients with rheumatoid arthritis

Behavioural problems – fish oil supplements and DHA in particular may help to improve behavioural problems in children. These include short attention span and restlessness. DHA is especially important in helping to regulate cognitive performance and may even help boost children’s school abilities by enhancing learning.

Healthy pregnancy and healthy baby – getting enough omega-3s is important for the healthy development of a baby’s brain, nervous system and sight. The human brain has a growth spurt during the last trimester of pregnancy and in the months after birth. This is when the DHA in the brain triples so getting enough is essential.

Not all fish oil supplements are created equal

Dr Alex Richardson from the UK charity Food and Behaviour Research is one of the world’s leading researchers into omega-3s. She has voiced her concerns about the poor quality of many fish oil supplements saying: ‘Not all kinds of omega-3s have the same health benefits.’

One of the main problems with some supplements she says is that products can contain little, if any of the important forms of omega-3s for human health, EPA and DHA. Look for a supplement that contains 1000mg omega-3s.
