Leading science professors have answered the most frequently asked questions people have about their health and nutrition.

Dr. Karl Kruszelnicki, a graduate of medicine and biomedical engineering, and Claire Collins, a laureate professor of nutrition and dietetics at Newcastle University, teamed up to reveal whether milk really causes acne and whether fasting helps weight loss on the Triple J Science with Dr. Karl podcast.

They explained how you can help your skin glow by eating brightly colored vegetables, and why intermittent fasting is just one of the ways you can lose weight.

'Drinking milk leads to an increase in the levels of a chemical called insulin-like growth factor, and the levels of insulin in the blood, which are thought to be the trigger for acne worsening,' Claire said (stock image)

1. Does milk cause acne, and do sugar and dairy products really affect your skin and cause breakouts?

The first question put to Claire and Dr. Karl was asked a question of whether milk and dairy products cause pimples.

“Drinking milk increases the levels of a chemical called insulin-like growth factor, and insulin levels in the blood, which are believed to be the trigger for acne worsening,” Claire explained.

‘It is very surprising that they have found in studies that this does not occur when eating cheese.’

The nutrition and diet expert added that if you want to prevent acne breakouts, you should aim for foods with a lower glycemic index, such as sweet potato instead of potato and whole grain bread instead of white bread.

This will greatly help your complexion.

“Studies have shown that if you want to be the best looking person in the room, you really need to boost your fruit and vegetable intake,” added Claire.

‘We did an experiment with our students where we gave some of them a box of really brightly colored vegetables for the week, and another with really boring and low levels.

In just four weeks, they glowed so far that you could really notice it. This works for men and women. ‘

2. Does intermittent fasting really work?

Intermittent fasting is one of the most popular ways for men and women to lose weight.

Whether it’s the 5: 2 Diet or the 16: 8 Diet, thousands of men and women swear by eating more in some ramen and less in others for achieving their weight loss goals.

But Claire explained that while fasting diets can work, there are many effective ways to manage your weight:

“Whether you’re the tortoise and take it slow, or the hare and do it all super fast, studies show everyone gets the same results,” Claire said.

She said intermittent fasting won’t always work for everyone.

3. Is there any reason why I have “cheese dreams”?

Many struggle with extremely vivid dreams after eating cheese, especially blue cheese, but Dr. Karl and Claire agreed that not much scientific literature exists on it.

“Cheese contains the amino acid tryptophan, which can turn into serotonin and be converted into relaxation and drowsiness,” said Dr. Karl.

There’s a 2005 study showing how cheese can have an effect on our drams.

“In the study, people were asked to have 20 grams of cheese half an hour before going to bed, and then write down their dreams and write them down as soon as they woke up.”

Dr. Karl said the study found that 83 percent of people who had red Leicester cheese had pleasant dreams about their childhood, while those who ate cheddar cheese had dreams about celebrities.

“The study found that Cheshire cheese led to dreams no more than half the time,” he said.

“There is a lot of anecdotal evidence about cheese, but no hard science.”

4. Why do you get hungry during your period?

Finally, the duo were asked why we often get hungry during our periods.

“This could be related to a few things,” Claire said.

Pregnancy cravings are thought to refer to a change in hormonal status, and that can happen during your period as well.

“That’s also why everyone’s cravings are different.”

The nutritionist added that we often want to eat more right before our period, because it is our body that subtly tells us to stock up for menstruation.
