But our consumption of vegetable oil has increased considerably since the 1960s, and the health effects of high intakes are a source of scientific debate.

What researchers agree on is that vegetable oils such as safflower, sunflower, corn, cottonseed and soybean oils, are rich in a type of fat known as linoleic acid. That acid can lower LDL or "bad" cholesterol when it replaces saturated fats in the diet (which primarily come from animal sources).

Global market research company Mintel monitors the way new food and drink products perform in the market while surveying consumers to understand their eating habits.

Justin Nell from the company's Australia and New Zealand arm is in Adelaide to speak at the Food South Australia Summit and says these are the biggest trends playing out in 2017.

"Salad cakes" -- a new craze in Japan -- offer exactly that experience.

Nagoya native Mitsuki Moriyasu, a cafe owner and food stylist, in 2015 invented what she calls the "Vegedeco Salad" (decorated vegetables) as a guilt-free alternative to traditional baked goods.

These sinless sweets substitute cream "frosting" for that made out of tofu, a "sponge" base for one of soy powder, eggs and vegetable oil, while the rainbow hues that decorate the "icing" come from natural vegetable colorings such as red beetroot juice.

The problem - called nocturia - which mainly affects the over-60s, leads to disrupted sleep and can significantly affect people's lives.

In a study of more than 300 volunteers, researchers found that reduced salt intake led people to urinate less.

Advice to follow a sensible diet could help improve symptoms, UK doctors said.

The researchers, from Nagasaki University, presented their findings at the European Society of Urology congress in London.

That's been the premise and promise of the organic movement since its origins in the 1920s: farming that's healthy, ecological, and socially just.

Many people -- from consumers and farmers to scientists and international organizations -- believe that organic agriculture can produce enough nutritious food to feed the world without destroying the environment, while being more resilient to climate change and improving the livelihoods of farmers.

Each season when the eel was spawning along the Parramatta River, they would gather with other Indigenous tribes to celebrate and share stories.

After 1788, those practices were slowly lost as colonial settlers moved into the area.

On Sunday the annual Eel Festival at Elizabeth Farm in Rosehill will give visitors a chance to understand the ways of the Dharug people and how significant eel was to the way they lived.

You're not alone. About 76% of adults may experience some type of hangover after a drinking session, according to a study published in the journal Addiction in 2008.

Hangover symptoms include fatigue, dehydration, a headache or muscle aches, dizziness, shakiness, rapid heartbeat -- you get the idea. It's the worst.

When he was growing up in the 1960s, vegetable oil was still a precious commodity and used sparingly.

Fast-forward to today and oil is now so abundant and cheaply available that most of us use it liberally in our cooking - chucking it in anything from salad dressings to deep fat frying.

It's not only in our home cooking, oil is also an ingredient in most of the items we buy from the supermarket.

It depends on the kind of rice you choose.

White rice is considered a nutritionally inferior "refined grain" because its bran and germ are removed during the milling process, which strips away B vitamins, iron and fiber. Though white rice is typically enriched with iron and B vitamins, fiber is not added back.

Brown rice is the same thing as white rice but is a "whole grain," because only its inedible outer husk is removed. Since brown rice retains its bran and germ, it's a better source of antioxidants, vitamin E and fiber.

Nuts are rich in heart-healthy polyunsaturated fats and monounsaturated fats, which lower LDL or "bad" cholesterol; plus, they are a good source of phytosterols, compounds that help lower blood cholesterol.

They are packed with fiber, protein, vitamins and minerals, including folate, vitamin E, potassium and magnesium.
