Diet

Research suggests that sticking tocertain dietsor eating patterns may nourish your brain in a way that delays or stops PD from manifesting.

The Mediterranean Diet

TheMediterranean dietis rich in fruits, vegetables, olive oil, fish, and whole grains. It is associated with both a decreased risk of PDand a delayed onset ofParkinson’s disease symptoms.

While it’s not entirely clear how, experts suspect that the various antioxidant and anti-inflammatory-rich components of the Mediterranean diet alter the brain in such a way that the death of dopamine-producing nerve cells is slowed or stopped.

The Mediterranean diet also limits your intake of dairy products, which are associated with an increased risk of PD.

A distinctive and hallmark feature of the Mediterranean diet is that it embraces the concepts of sustainability and balance, meaning it does not promote an overly restrictive way of eating.

Basic Concepts of the Mediterranean DietThe components of a Mediterranean diet include:Eat mainlyplant-based foods, such as a variety of fruits and vegetables, along with whole grains, nuts, and legumes, including lentils, chickpeas, beans, and peas.Consume a small amount of low-fat protein, either chicken or fatty fish, such as salmon, albacore tuna, or mackerel, a few times per week.Limit red meat to a few times a month.Avoid salt and instead flavor your meals with spices and herbs.Drink red wine in moderation (one glass of wine with meals).Replace butter with a healthier fat like extra virgin olive oil.Limit dairy, including cream, milk, and ice cream.

The components of a Mediterranean diet include:

The MIND Diet

The MIND diet combines elements from the Mediterranean diet and theDietary Approaches to Stop Hypertension (DASH) diet. It is also linked to a lower risk of and delayed onset of Parkinson’s disease.

Like the Mediterranean diet, the MIND diet focuses on eating vegetables, whole grains, beans, and nuts. Olive oil is the primary source of fat.

The MIND diet also similarly discourages the consumption of butter, cheeses, fried foods, red meat, and pastries/sweets. Eating fatty fish is encouraged in the MIND diet, although not as many servings as in the Mediterranean diet.

What is unique about the MIND diet is that it recommends eating berries (not just any fruit) and leafy green vegetables, like kale and spinach.

Berries, like blueberries, raspberries, and blackberries, are rich in organic compounds calledflavonoids. Leafy green vegetables are also rich in flavonoids, as well as folate,vitamin E, and carotenoids.

Slow Cognitive DeclineFlavonoids, folate, vitamin E, and carotenoids have all been found in scientific studies to slow cognitive decline.

There may be a dose-response relationship.This means that the more hours of moderate to vigorous physical activity a person performs a week, the lower their potential risk for developing PD.

Until more is known, it’s best to follow physical activity guidelines from professional organizations, like the Centers for Disease Control and Prevention (CDC) and the American Heart Association (AHA).
